Affidavit of Loss for a Lost SIM Card in the Philippines

I. Overview

An Affidavit of Loss for a lost SIM card is a sworn written statement executed by the owner or registered user of a mobile number declaring that the SIM card was lost, misplaced, stolen, destroyed, or otherwise can no longer be found despite diligent search. In the Philippines, this affidavit is commonly required when a person wants to request a SIM replacement, protect themselves from unauthorized use, support a report to the mobile network provider, or document the loss for legal, banking, e-wallet, employment, or identity-verification purposes.

A SIM card is not merely a small telecommunications accessory. In modern Philippine practice, a mobile number is often connected to bank accounts, e-wallets, one-time passwords, government accounts, online shopping accounts, social media accounts, work communication platforms, delivery apps, and digital identity verification. Losing a SIM card can therefore create risks of fraud, unauthorized transactions, identity misuse, account takeover, phishing, or privacy breach.

The Affidavit of Loss helps create a formal record that the SIM card was lost and that the affiant is notifying relevant parties that any unauthorized use after the loss should not be attributed to the affiant, subject to proof and applicable law.


II. Meaning of an Affidavit of Loss

An affidavit is a written statement of facts voluntarily made under oath before a notary public or other officer authorized to administer oaths. An Affidavit of Loss specifically states the circumstances surrounding the loss of a document, item, card, certificate, or property.

For a lost SIM card, the affidavit usually states:

The affiant’s name, citizenship, age, civil status, address, and identification details.

The mobile number connected to the lost SIM card.

The telecommunications provider.

The approximate date, time, and place of loss.

The circumstances of loss.

The efforts made to locate the SIM.

A declaration that the SIM remains missing.

A request or purpose, such as SIM replacement or blocking.

A statement that the affidavit is executed to attest to the truth of the loss.

A statement that the affiant will notify the provider if the SIM is found.

The affidavit must be signed by the affiant and notarized.


III. Why an Affidavit of Loss Is Needed for a Lost SIM Card

An Affidavit of Loss may be required or useful for several reasons.

1. SIM Replacement

Mobile network providers commonly require proof that the registered owner is requesting replacement of a lost SIM. The affidavit helps show why the original SIM cannot be presented.

2. Number Retention

If the subscriber wants to keep the same mobile number, the provider may require identity verification and documents proving loss. The affidavit supports the request to issue a replacement SIM with the same number.

3. Blocking or Deactivation

If the SIM may have been stolen or may be used by another person, the subscriber may request temporary blocking, suspension, or deactivation. The affidavit may support that request.

4. Protection Against Unauthorized Use

The affidavit creates a sworn record that the SIM was lost as of a certain date. This may be useful if the number is later used for suspicious transactions, messages, calls, or account access.

5. Bank, E-Wallet, and Online Account Recovery

Many accounts use mobile numbers for one-time passwords. A bank, e-wallet provider, online platform, or employer may ask for an affidavit if the user needs to change the registered number or prove loss of SIM.

6. Police, Employer, or Administrative Records

If the SIM was lost with a phone, bag, wallet, company-issued device, or work account, an affidavit may be needed for records, investigation, insurance, or clearance.


IV. Legal Nature of a SIM Card

A SIM card is a subscriber identity module used to identify a mobile subscriber on a network. In practice, it is tied to a mobile number, subscriber account, registration data, and access to telecommunications services.

The physical SIM card may be replaceable, but the mobile number and account associated with it may have significant legal and practical value. It may be linked to:

Personal identity verification.

Banking authentication.

Electronic wallets.

Government portals.

Social media accounts.

Email recovery.

Messaging applications.

Business transactions.

Employment communication.

Two-factor authentication.

Online contracts and notices.

Because of this, losing a SIM card should be treated seriously.


V. Difference Between Losing a SIM Card and Losing a Mobile Phone

A person may lose only the SIM card, or may lose the entire phone containing the SIM.

The affidavit should be accurate.

If only the SIM card was lost, the affidavit should say so.

If the phone containing the SIM was lost, the affidavit may describe both the phone and the SIM.

If the phone was stolen, the affidavit should state the facts carefully and may be accompanied by a police report.

If the SIM was destroyed, damaged, or accidentally discarded, the affidavit should say that it was lost, destroyed, or could no longer be recovered.

Accuracy is important because false statements in an affidavit may have legal consequences.


VI. When to Execute an Affidavit of Loss

A person should execute an Affidavit of Loss as soon as reasonably possible after discovering that the SIM card is missing, especially when the SIM is linked to sensitive accounts.

Immediate action is recommended because a lost SIM may be used to:

Receive one-time passwords.

Reset passwords.

Access banking or e-wallet accounts.

Impersonate the owner.

Send fraudulent messages.

Commit scams.

Access personal contacts.

By executing the affidavit promptly and reporting the loss to the provider, the subscriber can reduce the risk of unauthorized use.


VII. Immediate Steps After Losing a SIM Card

Before or alongside preparing an affidavit, the owner should consider doing the following:

Contact the mobile network provider immediately.

Request temporary blocking or suspension of the lost SIM.

Ask about SIM replacement requirements.

Change passwords of accounts linked to the number.

Remove the number as recovery method where necessary.

Notify banks and e-wallet providers if the number is linked to financial accounts.

Monitor suspicious transactions.

Report theft to police if the SIM or phone was stolen.

Inform contacts if the number may be used for scams.

Secure email accounts and messaging applications.

The affidavit is important, but it should not be the only step.


VIII. Contents of an Affidavit of Loss for a Lost SIM Card

A proper affidavit should contain the essential facts clearly and truthfully.

1. Personal Details of the Affiant

The affidavit should identify the person making the sworn statement.

Common details include:

Full name.

Age.

Citizenship.

Civil status.

Residence address.

Government-issued ID details.

Contact details, if applicable.

If the affiant is acting for a company, minor, deceased person, or another person, authority must be stated and supported.

2. Identification of the SIM Card

The affidavit should identify the lost SIM as specifically as possible.

It may include:

Mobile number.

Network provider.

Whether prepaid or postpaid.

Account name, if applicable.

SIM serial number, if known.

Date of purchase or registration, if known.

Purpose of use, if relevant.

If the SIM serial number is unknown, the mobile number and provider are usually the most important details.

3. Circumstances of Loss

The affidavit should describe when and how the SIM was lost.

Examples:

The SIM card was inside a mobile phone that was lost while commuting.

The SIM card was misplaced during transfer to another device.

The SIM tray was lost.

The phone containing the SIM was stolen.

The SIM was accidentally discarded.

The SIM was damaged and later misplaced.

The SIM could no longer be found after moving residence.

The description should be factual and not exaggerated.

4. Diligent Search

The affidavit should state that the affiant made a diligent search but could not locate the SIM.

This may include checking:

Home.

Office.

Bag.

Wallet.

Vehicle.

Phone case.

SIM tray.

Storage box.

Lost-and-found office.

Transport terminal.

The statement of diligent search helps show that the loss is genuine.

5. Declaration of Non-Recovery

The affidavit should state that despite efforts, the SIM card remains lost and unrecovered.

6. Purpose of the Affidavit

The affidavit should state why it is being executed.

Examples:

For SIM replacement.

For blocking or deactivation.

For submission to the mobile network provider.

For submission to a bank or e-wallet provider.

For account recovery.

For record purposes.

For whatever legal purpose it may serve.

7. Undertaking

The affiant may state that if the lost SIM is later found, the affiant will not use it or will report it to the provider, especially if a replacement has already been issued.


IX. Who May Execute the Affidavit

1. Registered SIM Owner

The registered owner or subscriber is the proper person to execute the affidavit.

2. Authorized Representative

A representative may process the replacement, but the provider may still require the registered owner’s affidavit, authorization letter, Special Power of Attorney, and valid IDs.

3. Parent or Guardian of a Minor

If the SIM belongs to or is used by a minor, the parent or legal guardian may need to execute the affidavit, depending on the provider’s rules and registration details.

4. Corporate or Business Subscriber

If the SIM is company-issued, the affidavit may be executed by an authorized corporate officer or employee, supported by corporate authorization or company certification.

5. Representative of Deceased Subscriber

If the subscriber is deceased and the SIM is needed for estate, business, or account recovery purposes, the heirs or authorized representative may need additional documents. A simple affidavit of loss may not be enough.


X. Notarization Requirement

An Affidavit of Loss should be notarized. Notarization converts the private document into a public document and allows it to be accepted by institutions that require sworn statements.

To notarize, the affiant generally needs:

Personal appearance before the notary public.

Original valid government-issued ID.

The prepared affidavit.

Payment of notarial fee.

The notary verifies the identity of the affiant and administers the oath. The affiant signs the affidavit and declares under oath that its contents are true.

A person should not sign an affidavit without reading and understanding it.


XI. Valid IDs Commonly Accepted

The notary public and the mobile network provider may require valid identification.

Common government-issued IDs include:

Philippine passport.

Driver’s license.

UMID.

SSS ID.

GSIS ID.

PhilHealth ID, where accepted.

TIN ID, where accepted.

Postal ID.

Voter’s ID or voter certification.

PRC ID.

Senior citizen ID.

National ID or PhilSys-related identification, where accepted.

OWWA ID.

OFW ID.

Seaman’s book.

The exact accepted IDs may vary depending on the notary, provider, and institution.


XII. Affidavit of Loss and SIM Registration

SIM registration has made identity verification more important. A replacement SIM is usually issued only after the provider verifies that the person requesting replacement is the registered owner or authorized user.

The affidavit does not by itself prove ownership of the number. It is only one document. The provider may still require identity verification, account details, biometrics, proof of SIM registration, proof of ownership, recent load transaction, postpaid account documents, or other validation.

For prepaid numbers, providers may ask questions to verify use of the number, such as:

Last load amount.

Last reload date.

Frequently contacted numbers.

Date of activation.

Registration details.

Proof of ownership.

Linked account information.

For postpaid numbers, they may require account holder identification and account verification.


XIII. Affidavit of Loss for Prepaid SIM

For a prepaid SIM, the subscriber may need to prove that they are the registered user. The affidavit should state the mobile number and network provider, and may include how long the number has been used.

Additional documents may include:

Valid ID.

Proof of SIM registration.

Screenshots of account profile, if available.

SIM bed or card holder, if available.

Proof of recent load or transaction.

Provider-specific replacement form.

The provider may refuse replacement if identity cannot be verified.


XIV. Affidavit of Loss for Postpaid SIM

For a postpaid SIM, the registered account holder generally has a clearer account record with the provider.

Common requirements may include:

Affidavit of Loss.

Valid ID of account holder.

Account number.

Latest bill, if available.

Authorization letter or SPA if representative applies.

Company authorization for corporate accounts.

The provider may temporarily suspend the lost SIM and issue a replacement under the same account.


XV. Affidavit of Loss for Company-Issued SIM

A company-issued SIM may be registered under the employer or business entity. The employee using the SIM may not be the legal subscriber.

In such cases, the company may require the employee to submit an incident report or affidavit, while the provider may require company authorization.

The affidavit should clarify:

That the SIM was company-issued, if true.

The employee’s custody or use of the SIM.

The circumstances of loss.

Whether the phone or device was also lost.

Whether the loss was reported to the company.

That the affidavit is executed for company records and SIM replacement.

The company may have separate policies on replacement costs, disciplinary action, data security, or device accountability.


XVI. Affidavit of Loss When the SIM Was Stolen

If the SIM was stolen, especially with a mobile phone, wallet, or bag, the affidavit should state the facts of the theft. A police report may also be advisable or required.

The affidavit should avoid making accusations unless the affiant personally knows the facts. If the thief is unknown, it should state that the item was stolen by an unidentified person.

Example wording:

“On or about [date], while I was at [place], I discovered that my mobile phone containing my SIM card with mobile number [number] was missing. I believe it was stolen, and despite diligent efforts, I could no longer recover the same.”

If there was actual robbery, snatching, burglary, or theft, a police blotter or report may strengthen the record.


XVII. Affidavit of Loss When the SIM Was Misplaced

If the SIM was simply misplaced, the affidavit should not say it was stolen. It should state that it was lost or misplaced.

Example:

“While transferring my SIM card from one mobile phone to another, I inadvertently misplaced the SIM card. I searched my personal belongings and the surrounding area but could no longer find it.”

Truthful description matters.


XVIII. Affidavit of Loss When the SIM Was Damaged or Destroyed

Sometimes the SIM is not lost but damaged. If the physical SIM is still available, an Affidavit of Loss may not be appropriate. The provider may require a damaged SIM replacement instead.

However, if the SIM was damaged and later discarded or lost, the affidavit may state that it was destroyed or could no longer be produced.

Example:

“My SIM card was damaged and became unusable. Afterward, it was inadvertently misplaced and can no longer be located despite diligent search.”


XIX. Affidavit of Loss When the SIM Is Linked to a Bank or E-Wallet

If the lost SIM is linked to financial accounts, the owner should act quickly.

Recommended steps include:

Report the SIM loss to the mobile provider.

Request SIM blocking or replacement.

Notify the bank or e-wallet provider.

Change passwords.

Disable transactions if suspicious activity occurs.

Check account activity.

Report unauthorized transactions immediately.

The affidavit may be submitted to the bank or e-wallet provider to support number change, account recovery, or fraud investigation.

The affidavit should mention the mobile number, but it does not need to disclose account balances, passwords, PINs, or sensitive financial information.


XX. Affidavit of Loss and Unauthorized Transactions

If unauthorized transactions occurred after the SIM was lost, a simple affidavit of loss may not be enough. The person may need:

Police report.

Bank or e-wallet dispute form.

Telecom report.

Screenshots of unauthorized transactions.

Proof of date and time of loss.

Proof of account ownership.

Complaint affidavit.

Cybercrime or fraud report, depending on the case.

An Affidavit of Loss records the loss. It does not automatically prove that the owner is not liable for later transactions. Liability depends on the facts, timing, negligence, platform rules, security measures, and applicable law.


XXI. Affidavit of Loss and Identity Theft

A lost SIM may enable identity theft if another person gains access to verification codes. The owner should secure identity-linked accounts immediately.

Accounts to check may include:

Email.

Banking apps.

E-wallets.

Government portals.

Social media.

Messaging apps.

Cloud storage.

Work accounts.

Online shopping apps.

Delivery apps.

Crypto or investment platforms.

The affidavit may help show when the number became compromised, but preventive action is more important.


XXII. Affidavit of Loss and Data Privacy

A lost SIM may involve personal information. Text messages, contacts, authentication codes, and account links may be exposed if the SIM is used in another device or if the phone was lost with it.

The subscriber should consider:

Changing account passwords.

Revoking logged-in devices.

Contacting providers.

Enabling app-based authentication instead of SMS where possible.

Avoiding disclosure of OTPs.

Warning contacts about possible impersonation.

The affidavit should not include passwords, OTPs, security answers, or unnecessary sensitive personal data.


XXIII. Where to Get an Affidavit of Loss

An Affidavit of Loss may be prepared by:

A lawyer.

A notary public.

A legal documentation service.

The affiant using a template, subject to notarization.

Some mobile network provider stores may have their own preferred form or sample wording.

The document must be notarized to be accepted as an affidavit.


XXIV. Cost of an Affidavit of Loss

The cost depends on the notary public, location, length of document, and whether the affidavit is drafted from scratch.

Typical expenses may include:

Drafting fee, if prepared by a lawyer or document preparer.

Notarial fee.

Photocopying.

Transportation.

The notarial fee may vary by city and law office. The affiant should avoid fake notarization or documents notarized without personal appearance.


XXV. Risks of Fake or Improperly Notarized Affidavits

An affidavit notarized without personal appearance, valid ID, or proper notarial procedure may be questioned. A fake notarization can create legal problems.

Risks include:

Rejection by the provider or institution.

Administrative issues for the notary.

Possible criminal or civil liability.

Problems proving the affidavit’s authenticity.

The affiant should personally appear before the notary and use truthful information.


XXVI. False Statements in an Affidavit

An affidavit is made under oath. False statements may expose the affiant to liability, including perjury or falsification-related issues depending on the facts.

A person should not execute an Affidavit of Loss if:

The SIM was not actually lost.

The SIM is being used by another authorized person.

The SIM is being withheld due to a dispute.

The affiant is not the owner or authorized user.

The affidavit is being used to fraudulently take over another person’s number.

The date, place, or circumstances are knowingly false.

Truthfulness is essential.


XXVII. Can an Affidavit of Loss Alone Replace a SIM?

No. The affidavit is only one requirement. The mobile network provider controls the replacement process and must verify the subscriber’s identity.

The provider may still require:

Valid ID.

Personal appearance.

SIM registration verification.

Account verification.

Proof of ownership.

Payment of replacement fee.

Authorization document.

Company documents, for corporate accounts.

Police report, for theft cases.

Additional security checks.

The affidavit supports the request, but it does not guarantee approval.


XXVIII. Can Someone Else Use the Affidavit to Replace the SIM?

A representative may be allowed depending on provider rules, but the provider will usually require clear authority.

Possible documents include:

Notarized authorization letter.

Special Power of Attorney.

Valid ID of subscriber.

Valid ID of representative.

Affidavit of Loss signed by subscriber.

Corporate secretary’s certificate for company accounts.

Board resolution or company authorization, if applicable.

Because SIM replacement can allow access to sensitive accounts, providers may require strict personal verification.


XXIX. SIM Replacement and Number Recovery

If the provider approves replacement, a new physical SIM may be issued with the same mobile number. The old SIM may be deactivated or rendered unusable.

The subscriber should ask:

Will the old SIM be blocked permanently?

When will the replacement SIM activate?

Will SMS and calls immediately work?

Will mobile data work immediately?

Are there service fees?

Are e-wallet or banking OTPs affected?

Should linked accounts be reverified?

Will postpaid billing continue?

After replacement, the subscriber should test calls, SMS, mobile data, and OTP reception.


XXX. What If the Lost SIM Is Later Found?

If the lost SIM is later found after a replacement has been issued, the subscriber should not assume both SIMs can be used. The old SIM may already be deactivated.

The subscriber should:

Inform the provider if necessary.

Destroy the old SIM if instructed.

Avoid using a deactivated or compromised SIM.

Keep records of the replacement.

Update account security settings.

If the SIM was reported stolen, any later recovery should also be documented.


XXXI. Affidavit of Loss for Dual SIM Phones

If a phone had two SIM cards and both were lost, the affidavit should identify each SIM separately.

It should state:

Mobile number for each SIM.

Network provider for each SIM.

Whether both were inside the same device.

Whether both were prepaid or postpaid.

Whether both are being replaced.

Separate affidavits may be required depending on provider or purpose. If the SIMs are from different networks, each provider may require its own affidavit or certified copy.


XXXII. Affidavit of Loss for eSIM

An eSIM is not a physical SIM card in the traditional sense, but access credentials or a QR code profile may be lost, deleted, or compromised.

For eSIM-related loss, the affidavit should be worded accurately. Instead of saying the physical SIM was lost, it may state that the device containing the eSIM profile was lost, or that the eSIM profile became inaccessible.

The provider may have different requirements for eSIM reissuance.


XXXIII. Affidavit of Loss for SIM Card and Phone

If both the SIM and phone were lost, the affidavit may include details of the phone.

Useful phone details include:

Brand.

Model.

Color.

IMEI number, if known.

Serial number, if known.

Mobile number in the SIM.

Network provider.

Date and place of loss.

This can support phone blocking, police reporting, insurance, employer records, or device recovery.


XXXIV. Affidavit of Loss for SIM Used in Business

A business may use a SIM for customer service, delivery coordination, online sales, SMS alerts, or official communication. Loss of such SIM may affect operations and customer trust.

The affidavit may include:

Business name.

Registered owner of the SIM.

Business use of the number.

Authority of the affiant.

Circumstances of loss.

Request for replacement.

Declaration that unauthorized use after loss is not authorized by the business.

The business should notify customers or partners if there is risk of impersonation.


XXXV. Affidavit of Loss for SIM Used in Online Selling

Online sellers often use mobile numbers for marketplace accounts, delivery riders, e-wallets, customer inquiries, and OTPs.

If the SIM is lost, the seller should:

Secure marketplace accounts.

Change login credentials.

Contact platform support.

Notify e-wallet providers.

Replace or block the SIM.

Warn customers if scam risk exists.

The affidavit may support account recovery or change of registered number.


XXXVI. Affidavit of Loss for SIM Used by OFWs or Persons Abroad

If the subscriber is abroad, executing an affidavit may involve the Philippine embassy or consulate, a foreign notary with apostille, or other authentication procedure depending on where the document will be used.

A representative in the Philippines may need:

Consularized or apostilled affidavit.

Special Power of Attorney.

Copy of subscriber’s valid ID.

Representative’s valid ID.

Provider-specific authorization.

The requirements may vary. Some providers may require personal appearance or alternative verification.


XXXVII. Affidavit of Loss for Minor’s SIM

If the lost SIM is registered under a parent or guardian for a minor’s use, the parent or guardian should usually execute the affidavit.

The affidavit may state:

That the affiant is the parent or guardian.

That the SIM was used by the minor.

The mobile number and provider.

The circumstances of loss.

The request for replacement or blocking.

If the SIM is registered under the minor’s own details where allowed, additional verification may be required.


XXXVIII. Affidavit of Loss for Deceased Person’s SIM

If a SIM registered to a deceased person is lost and the heirs need access to the number for estate or account matters, the situation becomes more complicated.

The provider may require:

Death certificate.

Proof of relationship.

Estate or heirship documents.

Authorization from heirs.

Affidavit of loss, if applicable.

Court or settlement documents, in some cases.

A replacement may not be automatically granted because mobile accounts involve privacy and security concerns.


XXXIX. Should the Affidavit Include the SIM PIN or Account Password?

No. The affidavit should not include passwords, PINs, OTPs, recovery codes, security answers, or other confidential credentials.

It should identify the SIM and describe the loss, but it should not expose sensitive information.


XL. Should the Affidavit Include the IMEI Number?

If the phone was also lost, including the IMEI number may be useful. If only the SIM was lost, the IMEI may not be necessary.

The IMEI can help identify the lost device, but it does not identify the SIM itself. The SIM is better identified by mobile number, network provider, and SIM serial number if available.


XLI. Does an Affidavit of Loss Expire?

An affidavit generally does not have a formal expiration date, but institutions may require a recently executed affidavit for processing. A provider may reject an old affidavit if it wants current confirmation of loss.

For practical purposes, execute the affidavit close to the date of replacement or submission.


XLII. Can the Same Affidavit Be Used for Multiple Institutions?

Yes, if the affidavit is broadly worded and contains sufficient details. It may state that it is executed for submission to the telecommunications provider, banks, e-wallet providers, government agencies, and other concerned entities.

However, some institutions may require an original notarized copy or a document addressed to them specifically. The affiant may need several notarized copies.


XLIII. Original Versus Photocopy

Mobile providers and institutions may require the original notarized affidavit. Others may accept a certified true copy, scanned copy, or photocopy.

The affiant should prepare multiple original copies if the affidavit will be submitted to several institutions.


XLIV. Language of the Affidavit

An affidavit may be in English or Filipino. In practice, many affidavits in the Philippines are written in English. What matters is that the affiant understands the contents.

If the affiant does not understand English well, the affidavit should be translated or explained before signing. The jurat or notarial portion should properly reflect the oath.


XLV. Basic Format of an Affidavit of Loss

The usual structure is:

Title: Affidavit of Loss.

Venue: Republic of the Philippines, city or municipality.

Introductory statement identifying the affiant.

Numbered factual statements.

Statement of diligent search and non-recovery.

Statement of purpose.

Signature of affiant.

Jurat by notary public.

Notarial details.

The affidavit should be clean, consistent, and free from unexplained blanks.

XLIX. Common Mistakes in Affidavits of Loss for SIM Cards

Common mistakes include:

Failing to state the mobile number.

Failing to identify the network provider.

Using a wrong or outdated address.

Claiming theft when the SIM was merely misplaced.

Failing to mention that the SIM was inside a lost phone.

Including passwords or confidential information.

Using vague statements like “I lost my SIM” without circumstances.

Having the affidavit notarized without personal appearance.

Signing without reading.

Submitting photocopies when originals are required.

Failing to report the SIM loss to the provider promptly.

Failing to secure bank or e-wallet accounts linked to the number.


L. Can a Lost SIM Be Used for Fraud?

Yes. A lost SIM may be misused if another person can access it. The risk is higher if the SIM is not protected by a SIM PIN or if it is inside an unlocked phone.

Possible misuse includes:

Receiving OTPs.

Resetting passwords.

Sending scam messages.

Impersonating the owner.

Accessing e-wallets.

Accessing social media.

Receiving calls intended for the owner.

Using the number for fraudulent transactions.

This is why blocking and replacement should be requested promptly.


LI. SIM PIN and Preventive Measures

To reduce future risk, users may enable a SIM PIN. A SIM PIN requires a code when the SIM is inserted into a device or when the device restarts.

Other preventive measures include:

Use strong phone lock.

Enable device tracking.

Use app-based authentication where possible.

Avoid using SMS as the only account recovery method.

Do not share OTPs.

Keep SIM bed or proof of number ownership.

Keep records of network account details.

Update recovery numbers and emails.

Do not leave SIM cards loose in bags or wallets.


LII. Affidavit of Loss and Police Report

A police report is not always required for a lost SIM, especially if it was merely misplaced. However, it may be advisable or required if:

The SIM was stolen.

A phone was stolen.

A bag or wallet was stolen.

Unauthorized transactions occurred.

Identity theft is suspected.

The provider requests it.

The employer requires it.

Insurance is involved.

A police report and affidavit serve different purposes. The police report records the incident with law enforcement. The affidavit is the owner’s sworn statement.


LIII. Affidavit of Loss and Cybercrime Complaints

If the lost SIM was used for online fraud, account takeover, extortion, phishing, or unauthorized financial transactions, the matter may go beyond ordinary SIM replacement.

The victim may need to preserve evidence such as:

Screenshots.

Transaction receipts.

Messages.

Call logs.

Email alerts.

Bank notices.

E-wallet notices.

Provider reports.

Police report.

The affidavit of loss may be one supporting document, but a cybercrime or fraud complaint may require a more detailed complaint-affidavit.


LIV. Does the Affidavit Prevent Liability for Unauthorized Use?

Not automatically. An affidavit is evidence that the affiant claims the SIM was lost. It may help show date and circumstances, but liability for unauthorized transactions depends on many factors.

Relevant factors may include:

When the SIM was lost.

When the provider was notified.

Whether the user protected the phone or SIM.

Whether the user shared OTPs or passwords.

Whether the transaction occurred before or after reporting.

Whether the account provider followed security procedures.

Whether fraud was proven.

Whether negligence contributed to the loss.

The affidavit is useful, but it is not absolute immunity.


LV. Legal Effect of Notifying the Telecom Provider

Prompt notice to the telecom provider is important. Once notified, the provider may block or suspend the lost SIM, reducing risk of unauthorized use.

The subscriber should keep proof of report, such as:

Reference number.

Email confirmation.

Chat transcript.

Store acknowledgment.

SMS or app ticket.

Incident report number.

Date and time of call.

Name or ID of representative, if available.

This proof may be more important than the affidavit if a dispute arises over when the loss was reported.


LVI. Replacement Fees and Charges

Mobile providers may charge a replacement fee for lost SIM cards. Postpaid accounts may have charges reflected in billing. Prepaid replacement may require payment at the store or service center.

If the SIM was lost due to theft, the fee may still apply unless waived by the provider.

The affidavit itself does not exempt the subscriber from provider fees.


LVII. Can a SIM Be Replaced Without an Affidavit?

Sometimes a provider may replace a SIM based on identity verification alone, especially if the SIM is damaged and physically presented. However, for a lost SIM, an affidavit is commonly required because the old SIM cannot be surrendered.

The requirement depends on provider policy, account type, risk level, and circumstances.


LVIII. Affidavit of Loss for Lost SIM Bed or SIM Card Holder

If the SIM itself is not lost but the SIM bed, card holder, or original packaging is lost, an Affidavit of Loss may be needed only if the provider requires it for proof of ownership.

The affidavit should not say the SIM card was lost if only the SIM bed was lost. It should state exactly what was lost.


LIX. Affidavit of Loss for Lost SIM Registration Proof

If the subscriber loses proof of SIM registration but still has the SIM, the affidavit should state that the proof or document was lost, not the SIM card.

The provider may have other ways to verify registration.


LX. Use of Affidavit for Changing Registered Mobile Number

Banks, e-wallets, schools, employers, and government platforms may require an affidavit if the user cannot receive OTPs because the registered SIM was lost.

The affidavit may support a request to change the registered mobile number.

The institution may still require:

Valid ID.

Personal appearance.

Account verification.

Email verification.

Biometrics.

Security questions.

Police report, if fraud-related.

The affidavit alone does not compel the institution to change the number.


LXI. Use of Affidavit for GCash, Maya, Banking, and OTP Issues

When the lost SIM is linked to financial apps, the user may need to coordinate with both the telecom provider and the financial platform.

Possible scenarios include:

Replacing the SIM to regain access to OTPs.

Changing the mobile number registered to the wallet.

Freezing the account due to suspected compromise.

Disputing unauthorized transactions.

Updating KYC information.

The affidavit may be submitted as part of the platform’s verification process.


LXII. Use of Affidavit for Social Media and Email Recovery

If the number is linked to social media or email recovery, the affidavit may help if the platform asks for proof of loss or identity. However, many global platforms do not rely heavily on notarized Philippine affidavits and may use their own recovery systems.

The user should update recovery emails, backup codes, authentication apps, and trusted devices.


LXIII. Affidavit for Lost SIM Used in Two-Factor Authentication

A lost SIM can lock a user out of accounts that depend on SMS-based authentication. After replacement or recovery, users should consider using:

Authenticator apps.

Hardware security keys.

Backup codes.

Recovery email.

Trusted devices.

SMS OTP is convenient but vulnerable to SIM loss and SIM swap risks.


LXIV. SIM Swap Risk

SIM replacement can itself be abused by scammers who impersonate subscribers. Because of this, providers may strictly verify requests for replacement of lost SIM cards.

The affidavit should not be treated as a mere formality. It is part of a security process intended to prevent unauthorized SIM swaps.

Subscribers should never give their IDs, selfies, OTPs, or affidavit copies to suspicious persons claiming to help with replacement.


LXV. Can a Lost SIM Be Recovered by Another Person?

If another person finds the SIM, they should not use it. They may surrender it to the owner, provider, police, or appropriate lost-and-found office.

Unauthorized use of another person’s SIM may create civil, criminal, privacy, or fraud-related liability depending on the acts committed.


LXVI. Affidavit of Loss and Ownership Disputes Over Number

Sometimes two people claim the same mobile number, such as in cases involving family plans, company accounts, former employees, or numbers registered under another person’s name.

An Affidavit of Loss does not resolve ownership disputes. The provider will generally rely on registration records, account documents, and verification rules.

If the number is registered under another person’s name, the actual user may have difficulty replacing it without the registered owner’s cooperation.


LXVII. Lost SIM Registered Under Another Person’s Name

If the SIM is registered under another person’s name, the user should not falsely claim to be the registered owner. The proper approach is to ask the registered owner to execute the affidavit or authorize the replacement, subject to provider rules.

If the registered owner is unavailable, additional legal steps may be needed, but a false affidavit should never be used.


LXVIII. Lost SIM Used by Family Members

A parent, spouse, sibling, or child may be using a SIM registered to another family member. For replacement, the registered owner usually needs to be involved.

The affidavit may state the relationship and actual use, but provider approval depends on registration records and authorization.


LXIX. Lost SIM Used by Former Employee

If a former employee loses or retains a company SIM, the company should act promptly to suspend, replace, or reassign the number.

The company may need:

Employee incident report.

Affidavit of loss from employee.

Company authorization.

Proof of corporate account.

Clearance documents.

Request to provider.

If the employee refuses to cooperate, the company may rely on account ownership documents and provider procedures.


LXX. Affidavit of Loss for SIM Lost During Travel

If the SIM was lost while traveling, the affidavit should state the travel location and circumstances as accurately as possible.

Example:

“On or about [date], while traveling from [place] to [place], I discovered that my SIM card/mobile phone containing the SIM was missing.”

If lost abroad, the subscriber may need local police report, consular affidavit, or other authentication depending on the provider’s requirements.


LXXI. Affidavit of Loss for Multiple Lost Items

If the SIM was lost together with other items, the affidavit may include all lost items in one document, such as:

Mobile phone.

SIM card.

Wallet.

IDs.

ATM card.

Company ID.

Driver’s license.

However, if different institutions require separate affidavits, multiple documents may be more practical.

The affidavit should clearly identify the SIM and mobile number.


LXXII. Affidavit of Loss and Insurance Claims

If the lost SIM was inside an insured phone or company device, the affidavit may support an insurance or accountability claim. Insurers may also require a police report, proof of ownership, purchase receipt, and incident report.

The affidavit should be consistent with the insurance claim.


LXXIII. Affidavit of Loss and Employer Accountability

If the SIM or phone was company-issued, the employee may be required to explain the loss. The affidavit may support:

Asset replacement.

Incident reporting.

IT security response.

Payroll or HR documentation.

Clearance.

Insurance.

Disciplinary review.

The employee should be accurate. If negligence caused the loss, the affidavit should not conceal material facts.


LXXIV. Affidavit of Loss and Corporate Authority

For corporate accounts, an affidavit may need to be accompanied by:

Secretary’s certificate.

Board resolution.

Authorization letter.

Company ID of representative.

Government ID of representative.

SEC registration documents.

Latest GIS, if required.

Account documents.

The provider must confirm that the person requesting replacement is authorized to act for the corporation.


LXXV. Affidavit of Loss and Special Power of Attorney

A Special Power of Attorney may be needed if the registered owner cannot personally process SIM replacement.

The SPA should authorize the representative to:

Report the loss.

Request blocking or suspension.

Apply for replacement SIM.

Receive the replacement SIM.

Sign provider forms.

Submit documents.

Represent the owner before the telecom provider.

Because SIM replacement is sensitive, some providers may still require personal appearance or additional verification.


LXXVI. Affidavit of Loss and Remote Processing

Some providers may allow partial online reporting, but SIM replacement commonly requires identity verification and may require store visit or delivery procedures. The affidavit may be uploaded or physically submitted depending on provider policy.

The subscriber should beware of fake customer service pages and phishing links.


LXXVII. Affidavit of Loss and Unauthorized Representative

A person should not allow an untrusted representative to process SIM replacement. The representative may gain control of the mobile number and related accounts.

If a representative is needed, the subscriber should use a trusted person and limit the authority in writing.


LXXVIII. The Role of the Notary Public

The notary public does not verify whether the SIM was truly lost. The notary verifies the identity of the affiant and administers the oath.

The truthfulness of the affidavit remains the responsibility of the affiant.


LXXIX. Jurat Versus Acknowledgment

An affidavit should have a jurat, not merely an acknowledgment. A jurat shows that the affiant swore to the contents before the notary.

The notarial wording usually begins with “Subscribed and sworn to before me.”

If the document only says “acknowledged before me,” an institution may question whether it is properly sworn.


LXXX. Competent Evidence of Identity

For notarization, the affiant must present competent evidence of identity. The notary records the ID details in the notarial portion.

The name in the affidavit should match the ID. If there are discrepancies, such as married name, maiden name, middle initial issues, or suffix errors, these should be clarified.


LXXXI. Personal Appearance Before Notary

The affiant should personally appear before the notary. Remote or fake notarization may not be accepted and may create legal problems.

The notary should not notarize a document for a person who is not physically present, subject to applicable notarization rules and recognized exceptions, if any.


LXXXII. How Specific Should the Circumstances Be?

The affidavit should be specific enough to be credible but not unnecessarily detailed.

Good:

“On 10 March 2026, while commuting from Quezon City to Makati, I discovered that my mobile phone containing my SIM card was missing.”

Too vague:

“I lost my SIM.”

Too speculative:

“My coworker stole my SIM,” if the affiant has no personal knowledge.

The affidavit should stick to facts personally known to the affiant.


LXXXIII. Should the Affidavit State That the SIM Was Not Used for Illegal Purposes?

It may state that the affiant did not authorize any person to use the SIM after the loss. However, it should not make broad claims beyond personal knowledge.

Acceptable wording:

“I have not authorized any person to use the said SIM card after its loss.”

Avoid unsupported wording:

“The SIM was never used for any illegal activity by anyone.”

The affiant cannot know what an unknown finder or thief did after the loss.


LXXXIV. Should the Affidavit State the Exact Time of Loss?

If known, yes. If not known, it may use “on or about” and state when the loss was discovered.

Example:

“On or about 5 May 2026, at around 7:00 p.m., I discovered that…”

If the exact time is unknown:

“On or about 5 May 2026, I discovered that…”

Accuracy is better than false precision.


LXXXV. Should the Affidavit Mention the Last Known Location?

Yes, if known. It helps establish circumstances and credibility.

Example:

“The SIM card was last in my possession at my residence in Cebu City.”

If the SIM was in a phone:

“The mobile phone containing the SIM card was last seen in my bag while I was at…”


LXXXVI. What If the Affiant Cannot Remember the Mobile Number?

If the affiant cannot remember the mobile number, replacement may be difficult. The affidavit may identify the SIM by provider, account name, SIM serial number, phone records, or other details if available.

For a useful affidavit, the mobile number should be included whenever possible.


LXXXVII. What If the SIM Number Belongs to a Deactivated Account?

If the SIM has been inactive or deactivated, replacement may not be available. The affidavit may still document loss, but the provider’s account rules will govern whether the number can be recovered.


LXXXVIII. Does a Notarized Affidavit Make the Facts Conclusive?

No. A notarized affidavit is evidence of the affiant’s sworn statement. It does not conclusively prove the facts against all persons. It may be challenged if false, inconsistent, or unsupported.

For SIM replacement, the provider still decides whether the documents are sufficient.


LXXXIX. Practical Checklist Before Going to the Provider

Before going to the provider, prepare:

Notarized Affidavit of Loss.

Original valid government ID.

Photocopy of ID.

Proof of SIM registration, if available.

SIM bed or packaging, if available.

Proof of account ownership.

Postpaid account number or bill, if applicable.

Police report, if stolen and required.

Authorization letter or SPA, if representative.

Company authorization, if corporate account.

Payment for replacement fee.

List of linked accounts to update after replacement.


XC. Practical Checklist for the Affidavit

Before signing, check:

Is the name correct?

Is the address correct?

Is the mobile number correct?

Is the provider correct?

Is the date of loss or discovery correct?

Are the circumstances truthful?

Does it say diligent search was made?

Does it state the purpose?

Does it avoid passwords and sensitive information?

Does it have a jurat?

Are ID details correct?

Are there no blank spaces?

Is each page signed or initialed if required?

XCIII. Important Clauses to Include

A strong affidavit should include these clauses:

Identification of the SIM and number.

Statement of ownership or registered use.

Date and place of loss or discovery.

Circumstances of loss.

Diligent search.

Non-recovery.

No voluntary transfer.

No authorization for others to use it.

Purpose of replacement or blocking.

Undertaking if found.

These clauses reduce ambiguity.


XCIV. Clauses to Avoid

Avoid clauses that are false, speculative, or unnecessary.

Examples:

“I am not liable for any transaction ever made using the number.”

“The finder is criminally liable,” without knowing facts.

“The provider is required to replace my SIM immediately,” if this depends on verification.

“I lost the SIM on an exact date and time,” if unknown.

“I am the owner,” if the SIM is registered to another person.

“I authorize anyone holding this affidavit to claim my SIM,” because that can be dangerous.


XCV. Affidavit of Loss and Consent to Process Personal Data

Some providers may have separate forms for data privacy consent. The affidavit itself does not need to include broad consent unless required.

When submitting documents, the subscriber should provide them only to official provider channels and trusted institutions.


XCVI. Keeping Copies

The affiant should keep copies of:

Signed affidavit.

Notarized affidavit.

Provider acknowledgment.

Replacement receipt.

Blocking request.

Police report, if any.

Bank or e-wallet reports.

IDs submitted.

These records may be needed if disputes arise.


XCVII. How Many Copies to Prepare

It is practical to prepare at least two or three notarized originals if the affidavit will be used for multiple purposes:

One for the telecom provider.

One for bank or e-wallet.

One for personal records.

Some institutions keep the original and do not return it.


XCVIII. If the Provider Rejects the Affidavit

A provider may reject an affidavit if:

It is not notarized.

The mobile number is missing or wrong.

The affiant is not the registered owner.

The ID does not match.

The affidavit is too old.

The circumstances are unclear.

The notarial details are defective.

The document appears altered.

Additional requirements are missing.

The provider suspects fraud or SIM swap risk.

The subscriber should ask for the exact deficiency and correct it.


XCIX. If the SIM Is Lost but Still Active

The subscriber should request immediate blocking or suspension. If the SIM remains active, unauthorized persons may receive calls, messages, and OTPs.

A replacement request should not be delayed if the number is important.


C. If the Lost SIM Is Used After Loss

If the owner receives reports that the lost SIM is being used, they should:

Notify the provider immediately.

Request blocking.

Document the reported use.

Preserve screenshots and messages.

Notify affected contacts.

Inform banks and e-wallet providers.

File police or cybercrime report if fraud occurs.

The affidavit may be supplemented by a complaint-affidavit if illegal activity occurred.


CI. If the SIM Is Found Before Replacement

If the SIM is found before replacement and no unauthorized use occurred, the owner may no longer need replacement. If an affidavit has already been executed but not submitted, it should not be used to claim the SIM is still lost.

If the affidavit was already submitted, the owner should inform the institution that the SIM was recovered.


CII. If the SIM Is Found After Replacement

If a replacement SIM has been issued, the old SIM is usually deactivated. The owner should destroy or surrender the old SIM as instructed and continue using the replacement.


CIII. Best Practices for Drafting

Best practices include:

Use plain and accurate language.

Do not exaggerate.

Identify the mobile number clearly.

Describe the loss briefly but sufficiently.

State diligent search.

State the purpose.

Avoid unnecessary sensitive data.

Use correct notarial form.

Review before signing.

Prepare multiple copies if needed.


CIV. Practical Example: Lost SIM While Commuting

A subscriber lost a phone while riding public transportation. The phone contained the SIM used for banking OTPs. The subscriber should immediately call the provider to block the number, notify banks or e-wallets, execute an affidavit stating the loss, obtain a police report if theft is suspected, and request replacement after identity verification.

The affidavit should state the approximate date, route, discovery of loss, mobile number, provider, and diligent search.


CV. Practical Example: SIM Misplaced During Phone Transfer

A subscriber removed a SIM from an old phone to transfer it to a new phone but misplaced it. The affidavit should state that the SIM was lost during transfer, not stolen. The subscriber should request replacement and verify ownership with the provider.


CVI. Practical Example: Company SIM Lost by Employee

An employee assigned a company SIM loses it during fieldwork. The employee may execute an affidavit for company records. The company, as account holder, may request blocking or replacement through an authorized officer. The employee may also need to submit an incident report.


CVII. Practical Example: SIM Linked to E-Wallet

A user loses a SIM linked to an e-wallet and cannot receive OTPs. The user should request SIM replacement from the telecom provider. If replacement is not possible, the user may submit the affidavit to the e-wallet provider to change the registered number, subject to account verification.


CVIII. Frequently Asked Questions

1. Is an Affidavit of Loss required for a lost SIM card?

It is commonly required for SIM replacement, especially when the original SIM cannot be surrendered. The exact requirement depends on the provider.

2. Can I make my own Affidavit of Loss?

Yes, but it must be truthful, properly drafted, signed, and notarized. The provider may have preferred wording or additional requirements.

3. Do I need a lawyer?

A lawyer is not always necessary, but legal assistance may help if the loss involves fraud, unauthorized transactions, company property, or disputed ownership of the number.

4. Do I need a police report?

Not always. A police report is advisable if the SIM or phone was stolen, if unauthorized transactions occurred, or if the provider or institution requires it.

5. Can I replace a SIM registered under another person’s name?

Usually, the registered owner must request replacement or authorize it. Do not execute a false affidavit claiming ownership.

6. Can I use the affidavit to recover my e-wallet?

It may support recovery, but the e-wallet provider will still require account verification.

7. Should I include my OTPs or passwords in the affidavit?

No. Never include OTPs, passwords, PINs, or security answers.

8. What if I later find the SIM?

Inform the provider if necessary. If a replacement has already been issued, the old SIM may no longer work and should not be used.

9. Can the affidavit protect me from scams made using the lost SIM?

It may help show that the SIM was lost, but it does not automatically eliminate liability. Prompt reporting and evidence are important.

10. Does notarization prove that the SIM was really lost?

No. Notarization proves that the affiant personally swore to the statement before the notary. The truth of the statement may still be verified or challenged.


CIX. Key Legal Principles

An Affidavit of Loss is a sworn statement of facts.

It must be truthful.

It should be notarized.

The registered SIM owner is usually the proper affiant.

The affidavit supports but does not guarantee SIM replacement.

The mobile provider may require additional verification.

A lost SIM should be reported immediately.

The owner should secure linked bank, e-wallet, and online accounts.

False statements in an affidavit may create legal liability.

A SIM linked to financial and identity accounts should be treated as sensitive.


CX. Conclusion

An Affidavit of Loss for a lost SIM card in the Philippines is an important legal and practical document. It formally records that the SIM card connected to a specific mobile number has been lost and cannot be recovered despite diligent search. It is commonly used to request SIM replacement, blocking, deactivation, account recovery, or institutional verification.

Because mobile numbers are now tied to banking, e-wallets, OTPs, work accounts, government services, and digital identity, a lost SIM card should be treated as a security incident, not a minor inconvenience. The owner should promptly notify the telecommunications provider, secure linked accounts, monitor suspicious activity, and execute a truthful notarized affidavit when required.

The affidavit should clearly identify the SIM, state the mobile number and provider, describe the circumstances of loss, confirm diligent search, state that the SIM was not voluntarily transferred, and specify the purpose of the affidavit. It should not contain passwords, PINs, OTPs, or unsupported accusations.

A well-prepared Affidavit of Loss helps the subscriber document the loss, comply with provider requirements, and protect against later disputes. However, it is only one part of the process. The subscriber must still pass provider verification, follow SIM replacement procedures, and take immediate steps to secure all accounts connected to the lost number.
