Losing your SIM card in the Philippines disrupts far more than calls and texts. It can cut off access to OTPs for banking and government services, ride-hailing apps, GCash, work communications, and family contact. For many, the number itself holds years of registrations under the mandatory SIM Registration Act. Replacing it while keeping the same number almost always requires a notarized Affidavit of Loss. This document serves as your sworn proof of ownership and the circumstances of the loss.

This article explains what the affidavit is, its role under current Philippine law, exactly how to prepare and use one, practical differences across Globe, Smart, and DITO, real-world challenges for ordinary Filipinos and foreigners, costs, timelines, and answers to the questions people actually search.

What Is an Affidavit of Loss for a Lost SIM Card?

An Affidavit of Loss is a written statement you sign under oath before a notary public declaring that your SIM card has been lost and cannot be recovered despite reasonable efforts. It includes specific details about you as the registered subscriber, the exact mobile number, the telco, when and how the loss happened, and your request for a replacement SIM with the same number.

Telecom providers require it primarily for lost (as opposed to damaged or defective) SIMs because it creates a formal, verifiable record. This protects you from liability for any unauthorized use after the loss and helps the provider comply with identity verification rules before reissuing a SIM tied to your registered identity.

Legal Basis Under Philippine Law

The requirement flows from Republic Act No. 11934, the SIM Card Registration Act of 2022. This law mandates registration of all prepaid and postpaid SIMs and requires public telecommunications entities (Globe, Smart, DITO, and others) to verify subscriber identity for any replacement or SIM swap. The affidavit supports that verification process by providing sworn evidence of legitimate ownership and the fact of loss.

Notarization itself is governed by the Supreme Court’s 2004 Rules on Notarial Practice (A.M. No. 02-8-13-SC, as amended). These rules require your personal appearance, competent evidence of identity through a valid government-issued photo ID, an oath or affirmation, and your signature in the notary’s presence. The resulting notarized document carries formal evidentiary weight for administrative and quasi-judicial purposes.

Telcos operate under Republic Act No. 7925 (the Public Telecommunications Policy Act of 1995) and National Telecommunications Commission regulations. Requiring a notarized affidavit for lost SIM claims aligns with their duty to prevent fraud, including SIM swap scams, while maintaining accurate registration records under RA 11934.

Making a false statement in the affidavit can expose you to liability under the Revised Penal Code, particularly provisions on false testimony or falsification.

Why You Need It and When It Applies

You need the affidavit mainly when requesting a replacement SIM that retains your existing mobile number after loss. It is the standard supporting document for:

Prepaid and postpaid accounts across major networks
Cases where the physical SIM or packaging proof is unavailable
Situations involving any doubt about ownership or circumstances

If your SIM is merely damaged or you want to upgrade to 5G/eSIM, some providers allow simpler processes with just ID and verification. For outright loss, the sworn affidavit is the norm.

Immediate action also matters for postpaid lines: unauthorized usage after loss can generate bills you may have to dispute later. The affidavit, combined with prompt reporting, helps establish the timeline.

Step-by-Step Guide to Preparing and Using the Affidavit

Report the loss immediately to protect your line and linked accounts.
Call your telco’s hotline or use official channels (Globe 211 or Messenger lost-phone option, Smart *888 or store reporting, DITO app or hotline). Request temporary barring or suspension. This stops calls, texts, and data usage right away. At the same time, notify banks, GCash, e-wallets, and any services using your number for OTPs. Change passwords and switch to alternative verification methods where possible.
Collect accurate details.
Prepare your full registered name (exactly as it appears in the telco’s records), current address, the precise mobile number, telco name, and any known SIM serial/ICCID. Note the date, approximate time, location, and circumstances of loss (for example, “left inside a Grab car along Commonwealth Avenue on [specific date]” or “fell from pocket while commuting on the MRT”). Describe your efforts to recover it. These specifics make the affidavit credible and reduce the chance of rejection.
Prepare the affidavit.
Use a template from a notary public or law office near a telco store or municipal hall. Standard content covers your personal circumstances, numbered declarations of ownership and loss details, the purpose (replacement SIM request), and a statement that you will testify if needed. Provide the facts clearly and truthfully. Many notaries keep ready templates specifically worded for lost SIM cards.
Have it notarized.
Go in person to a commissioned notary public. Bring one or two original valid government-issued photo IDs with signatures (PhilID, passport, driver’s license, UMID, PRC ID, or voter’s ID work well). The notary will verify your identity, administer the oath, witness your signature, and complete the jurat with seal and commission details. Fees typically range from ₱150 in the provinces to ₱300–₱500 in Metro Manila. Request two or three original copies. The process usually takes 15–45 minutes once you reach the notary.
Visit your telco store with the documents.
Go to an authorized Globe Store/Business Center, Smart Store, or DITO Experience Store. Requirements vary slightly:
- Globe often explicitly lists the notarized Affidavit of Loss plus one or two valid IDs and may take a selfie for verification.
- Smart primarily requires one valid government-issued ID from the registered owner, though many customers successfully submit an affidavit for lost cases to support verification.
- DITO commonly requests a valid ID together with the Affidavit of Loss for lost or stolen SIMs.
For postpaid accounts, expect extra account verification and possible settlement of any outstanding balance. Authorized representatives face stricter rules and usually need a Special Power of Attorney or additional affidavits plus IDs of both parties. Personal appearance by the registered subscriber is strongly preferred.
Pay the replacement fee and activate.
Fees are modest: often ₱0–₱99 depending on the provider and whether the line is prepaid or postpaid (examples from recent provider information include around ₱50 for some Globe prepaid replacements and ₱99 for postpaid; Smart frequently offers low or no extra charge beyond possible credit; DITO around ₱39). The new SIM (physical or eSIM where your device supports it) is issued with your same number. Activation usually occurs the same day or within 24 hours.
Update everything afterward.
Re-register or update your number in GCash, banks, government portals, apps, and any two-factor authentication setups. Test calls, texts, and data. Keep your copies of the affidavit and receipts for records.

Common Pitfalls, Challenges, and Real-Life Scenarios

Vague or incorrect details in the affidavit (wrong date, incomplete circumstances, or name mismatches with telco records) often cause rejection and require starting over. Always double-check facts against your own memory or any available records before notarization.

Long queues at popular branches or notaries during peak hours can add time. Going early or choosing less busy locations helps. Name discrepancies (common after marriage or with nicknames) may require extra supporting documents like a marriage certificate.

For postpaid users, delaying the report can lead to unexpected charges. File the temporary bar first, even if you need a day or two to prepare the full affidavit.

If the loss happened abroad, bar the line via hotline or roaming first. Execute the affidavit upon return to the Philippines or before a Philippine consular officer. Documents executed overseas may need consular authentication or apostille (for Hague Convention countries) plus translation if necessary, but most people complete the process locally after returning because telcos prefer straightforward Philippine notarization.

Foreigners and dual citizens follow the same core process. Use your passport (and ACR I-Card if you are a resident alien) as ID. The registered name must match. There are no constitutional restrictions on foreigners using Philippine telecom services.

If you suspect theft, file a police blotter or report at the nearest PNP station. It is not always mandatory for simple replacement but strengthens your documentation, helps with phone insurance claims, and is appreciated by some branches for higher-value accounts.

Frequent replacements or discrepancies can trigger additional verification steps under anti-fraud measures tied to RA 11934. Corporate or company-issued SIMs usually require an authorization letter on company letterhead plus the affidavit.

If you later recover the old SIM, notify your telco immediately. It will have been deactivated upon successful activation of the replacement and should not be used.

Frequently Asked Questions

Do I really need an Affidavit of Loss to replace a lost SIM card?
It is the standard supporting document required or strongly preferred by major telcos for lost SIM replacements to satisfy subscriber verification under RA 11934. While Smart’s primary stated requirement is a valid ID from the registered owner, Globe’s official guidance for lost cases highlights the notarized affidavit, and DITO commonly requests it. Preparing one smooths the process across providers.

How much does it cost to get an affidavit of loss notarized?
Expect ₱150–₱500 depending on location and the notary. Provincial areas and some government-affiliated notaries tend to be cheaper. Confirm the exact fee before proceeding.

Can I make the affidavit online or have it notarized remotely?
No. The Rules on Notarial Practice require your personal appearance before the notary for the oath and signing. Remote options are not generally accepted for this purpose by telcos.

What details must I include in the affidavit?
Your complete registered name and address, the exact mobile number and telco, the date/time/place and specific circumstances of the loss, efforts to recover it, confirmation of ownership, and the purpose of requesting a replacement SIM. Specific, truthful facts prevent rejection.

Is a police report also required?
It is not mandatory for most simple replacements but is recommended if theft is suspected or for insurance purposes. Some branches appreciate the extra documentation. Filing a blotter is usually quick and low-cost.

How long does replacement take after I submit everything?
Most people receive and activate the new SIM the same day or within 24 hours when documents are complete and the branch is not unusually busy.

What if my line is postpaid or heavily used for GCash and banking?
Report and bar the line first to limit liability. After replacement, immediately update your number in all linked services. You may need to visit bank or GCash branches with the new SIM and supporting documents for full restoration.

Can foreigners replace a lost Philippine SIM using an affidavit?
Yes. The process is the same. Bring your passport and ACR I-Card (if applicable). If you are abroad at the time of loss, bar the line remotely first, then complete the affidavit and replacement after returning or through Philippine consular channels (which may involve extra authentication steps).

Does the affidavit expire?
It has no strict expiration under law, but telcos expect it to be recent (ideally within a few days of the loss or report) so the facts remain current. An older affidavit may prompt requests for an updated one or additional verification.

What happens if I find my old SIM after getting the replacement?
Notify your telco right away. The old SIM is deactivated and blocked upon activation of the new one to prevent misuse. Do not attempt to use it.
