If someone opened a loan under your name using an old SIM card, treat it as both a financial dispute and a possible identity theft or fraud incident. Your immediate goals are to stop collection pressure, preserve evidence, prove you did not apply for or benefit from the loan, secure the SIM or number involved, and prevent the false loan from damaging your credit record. In the Philippines, the lender cannot simply make you pay because your old mobile number was used; it must be able to prove that you validly applied for and consented to the loan.

What usually happens in this situation

This problem often starts in one of these ways:

You receive text messages, calls, or emails demanding payment for a loan you never applied for.
A lending app contacts your family, employer, or phone contacts about a supposed debt.
You discover a loan under your name when applying for another loan, credit card, telco plan, or background check.
Your old SIM card or mobile number, which you stopped using, was reissued, accessed, or used by someone else.
Someone used your old number together with your name, ID photo, selfie, address, or other personal data to pass an online loan verification process.

The lender may say, “The loan was verified by OTP,” meaning a one-time password was sent to the SIM number. But an OTP alone does not automatically prove that you borrowed the money. It may prove only that someone had access to the number at that time.

That distinction matters. Under Philippine law, a valid loan is still a contract. A contract requires consent, object, and cause under Article 1318 of the Civil Code. If you did not apply, sign, click, authorize, receive, or benefit from the loan, the lender has a serious evidentiary problem.

Are you liable for a loan opened using your old SIM card?

Usually, you should dispute liability if you did not authorize the loan.

A loan is not valid against you merely because it used:

your old mobile number;
your name;
a copy of your ID;
a selfie or edited image;
an OTP sent to a SIM you no longer controlled;
a digital signature you did not make; or
an online lending app account you did not create.

Under Article 1311 of the Civil Code, contracts generally take effect only between the parties, their assigns, and heirs. If you were impersonated, you were not truly a consenting borrower.

However, in real life, the issue is not always resolved instantly. The lender may continue collection while it investigates. Credit reports may show the account until corrected. Online lenders may use automated collection systems. That is why you need a written dispute and evidence trail as early as possible.

Legal basis in the Philippines

Several Philippine laws may apply, depending on how the loan was opened and how the lender or collector behaves.

Issue	Possible legal basis	Why it matters
Loan made without your consent	Civil Code, Articles 1318 and 1311	A valid contract requires consent, and contracts generally bind only the parties.
Use of your identity online	RA 10175, Cybercrime Prevention Act of 2012	Computer-related identity theft may apply when someone intentionally uses identifying information without right.
Use of false documents or fake application details	Revised Penal Code, including falsification and estafa provisions	Fake IDs, false signatures, or deceit to obtain money may create criminal liability.
Fraud involving account numbers, credit devices, codes, or other access devices	RA 8484, Access Devices Regulation Act of 1998, as amended by RA 11449	May apply where access devices, account numbers, cards, codes, or similar instruments are fraudulently used.
SIM registration and misuse	RA 11934, SIM Registration Act	Requires SIM registration and penalizes certain acts involving false registration, transfer, sale, or misuse.
Misuse of your personal data	RA 10173, Data Privacy Act of 2012	Gives data subjects rights to access, correction, objection, and complaint before the National Privacy Commission.
Lending company misconduct	RA 9474, Lending Company Regulation Act of 2007 and SEC rules	Lending companies and financing companies are regulated by the Securities and Exchange Commission.
Harassment, shaming, or abusive collection	SEC Memorandum Circular No. 18, Series of 2019	Prohibits unfair debt collection practices by financing and lending companies.
Failure to handle your financial complaint properly	RA 11765, Financial Products and Services Consumer Protection Act	Financial service providers must have consumer assistance mechanisms and fair complaint handling.
Wrong credit report entry	RA 9510, Credit Information System Act	Allows disputes of inaccurate, outdated, incomplete, or misleading credit information.

First 24 hours: what to do immediately

1. Do not admit the debt

When speaking to the lender or collector, avoid saying:

“I will pay later.”
“Can I get a discount?”
“Please restructure my loan.”
“I borrowed but I forgot.”

Instead, say clearly:

“I dispute this loan. I did not apply for it, authorize it, receive the proceeds, or benefit from it. Please mark the account as disputed and send me the complete loan application records, verification logs, disbursement details, and documents used.”

Keep the tone calm. You are building a record, not arguing with a collector.

2. Preserve all evidence

Take screenshots and save copies of:

text messages and call logs;
collection notices;
emails;
app notifications;
loan account number or reference number;
name of the lender, app, or collection agency;
payment instructions or QR codes;
threats, insults, or contact-list harassment;
proof that you no longer used or controlled the SIM;
proof of your current number and address;
ID loss reports, if any;
travel records or work records showing you could not have applied, if relevant.

Do not delete messages even if they are upsetting. If you later file with the SEC, NPC, PNP, NBI, prosecutor, or court, screenshots with dates, phone numbers, and sender details can be important.

3. Contact the lender in writing

Send a written dispute by email, app ticket, website form, or registered mail. Written proof is better than a phone call.

Ask for:

the date and time of loan application;
the IP address or device used, if available;
the mobile number and email used;
the ID submitted;
the selfie or liveness-check result;
the e-signature or digital acceptance record;
the bank, e-wallet, or account where proceeds were released;
the loan agreement and disclosure statement;
the full name of the collecting entity;
confirmation that collection and credit reporting will be placed on hold while under dispute.

If the lender refuses to provide basic proof and only repeats that an OTP was used, note that in your complaint.

4. Secure the mobile number

If the number is still under your control, contact your telco immediately and ask for assistance in securing, replacing, or deactivating the SIM.

If you no longer control it, ask the telco whether the number is still registered to you, has been reissued, or was the subject of SIM replacement. Telcos may not release everything informally because of privacy and security rules, but your inquiry creates a record.

For SIM-related concerns, you may also use the complaint channels of the National Telecommunications Commission, including telco complaints, text scam reports, and SIM-blocking assistance where available.

5. File a police blotter or cybercrime report

A barangay blotter or police blotter helps document that you promptly denied the loan. It is not the same as a criminal conviction, but it is useful evidence.

For online loan fraud, identity theft, fake accounts, or SIM-related cyber activity, report to:

your local police station;
the PNP Anti-Cybercrime Group;
the NBI Cybercrime Division; or
the Office of the City or Provincial Prosecutor if you are ready to file a criminal complaint.

Bring printed screenshots, valid ID, proof of your mobile number history, and the lender’s messages.

Step-by-step process to dispute the loan

Step 1: Identify the type of lender

The correct complaint office depends on who supposedly granted the loan.

Lender type	Usual regulator or office
Lending company or financing company, including many online lending apps	Securities and Exchange Commission
Bank, credit card issuer, e-wallet, electronic money issuer, or BSP-supervised financial institution	Bangko Sentral ng Pilipinas
Cooperative lender	Cooperative Development Authority
Informal individual lender	Police, prosecutor, barangay if applicable, or civil courts depending on facts
Unknown app or suspicious lender	SEC, NPC, PNP/NBI cybercrime, and app store reporting channels

Many online lending apps are tied to lending or financing companies regulated by the SEC. You can check SEC channels such as the SEC iMessage complaint system and SEC lists of registered entities or recorded online lending platforms when available.

Step 2: Send a formal dispute to the lender

Your written dispute should be simple but complete.

Include:

your full name;
the alleged loan account number;
the old SIM number involved;
a statement that you did not apply for or authorize the loan;
a request to suspend collection;
a request to stop credit reporting or mark the account as disputed;
a request for copies of all application and verification records;
copies of your evidence;
a deadline for written response, such as 7 to 15 calendar days.

Avoid emotional language. The strongest dispute letters are factual.

Sample wording you can adapt

I am formally disputing the alleged loan under my name and mobile number. I did not apply for this loan, authorize any person to apply for it, receive its proceeds, or benefit from it. Please immediately mark the account as disputed, suspend all collection activity, stop or correct any credit reporting, and provide copies of the loan application, verification records, submitted ID, selfie or liveness-check result, IP/device logs, disbursement account, loan agreement, and disclosure statement. I reserve all rights under the Civil Code, Data Privacy Act, Cybercrime Prevention Act, SIM Registration Act, Financial Products and Services Consumer Protection Act, and applicable SEC/BSP regulations.

Step 3: Ask where the proceeds went

This is often the key question.

If the lender released funds to a bank account, e-wallet, remittance center, or card that is not yours, that strongly supports your position. If the funds went to an account using your name but not controlled by you, that may show a wider identity theft problem.

Ask the lender to confirm:

account name;
masked account number;
financial institution or e-wallet used;
date and time of disbursement;
whether cash-out occurred;
whether the account passed KYC, or “know your customer,” verification.

The lender may redact some details, but it should still investigate.

Step 4: Escalate to the regulator

Escalate if the lender ignores you, keeps collecting, refuses to investigate, or reports the debt as yours.

Situation	Where to escalate
Lending app or financing company continues collection	SEC
Bank, e-wallet, credit card, or BSP-supervised entity is involved	BSP consumer assistance channels
Personal data was misused or exposed	National Privacy Commission
Credit report contains the false loan	Credit Information Corporation dispute process
Identity theft, fake documents, cyber fraud	PNP/NBI cybercrime or prosecutor
Harassment, threats, public shaming	SEC, NPC, police, and possibly prosecutor

Under RA 11765, financial service providers are expected to maintain a consumer assistance mechanism and handle complaints fairly. This means your complaint should not be brushed aside with a generic “OTP verified” response if you present a credible identity theft dispute.

Step 5: File with the National Privacy Commission if your data was misused

If the lender collected, processed, disclosed, or failed to protect your personal data, the Data Privacy Act may be relevant.

Examples include:

an online lending app used your contact list for collection;
collectors contacted your employer, relatives, or friends about a disputed debt;
the lender refuses to correct inaccurate personal information;
your ID, selfie, or personal data was used without authority;
the lender had a data breach that enabled identity fraud.

The National Privacy Commission provides information on filing complaints and complaint mechanics. NPC complaints generally require a verified or notarized complaint and supporting evidence. Prepare screenshots, IDs, correspondence, and witness statements if others were contacted.

Step 6: Dispute the credit record

A false loan can hurt future applications for credit cards, housing loans, car loans, postpaid plans, or business financing.

Check your credit report through the Credit Information Corporation or accredited credit bureaus. If the false loan appears, use the CIC’s Online Dispute Resolution Process.

The CIC dispute process may require:

a recent CIC credit report;
the 14-digit Transaction Reference Number, or TRN;
details of the disputed contract;
copies of your supporting documents;
liveness check or identity verification.

The CIC generally cannot just delete information on its own without going through the dispute process involving the submitting entity. That is why it is important to dispute both with the lender and with the credit reporting channel.

Documents to prepare

Document	Why it helps
Government ID or passport	Proves your identity when filing disputes and complaints.
Affidavit of denial or affidavit of identity theft	A sworn statement that you did not apply for, authorize, or benefit from the loan.
Police blotter or cybercrime report	Shows prompt reporting and supports fraud dispute.
Screenshots of collection messages	Proves collection activity, harassment, or disputed account details.
Old SIM proof	Shows your connection or loss of control over the number.
Telco correspondence	Supports claims about SIM loss, deactivation, replacement, or reassignment.
Lender correspondence	Shows whether the lender properly investigated.
Credit report	Required if disputing credit data.
Proof of non-receipt of proceeds	Bank/e-wallet statements may show you did not receive the loan.
ID loss report, if applicable	Useful if your ID was stolen or leaked.

Affidavit of denial: when it helps

An affidavit of denial is a sworn written statement where you state facts such as:

you did not apply for the loan;
you did not authorize anyone to apply for it;
you did not receive the proceeds;
the SIM number was old, lost, inactive, replaced, or no longer controlled by you;
you only learned of the loan on a specific date;
you immediately disputed it.

In the Philippines, affidavits are usually notarized. If you are abroad, you may execute documents before a Philippine Embassy or Consulate, or use notarization and apostille procedures depending on the country. If the country is part of the Apostille Convention, an apostille may be accepted for Philippine use. If not, consular authentication may be required.

For foreigners in the Philippines, a passport and ACR I-Card, if applicable, are commonly used for identity verification. Foreigners may file complaints in the Philippines when they are victims of fraud, data misuse, harassment, or unauthorized loans involving Philippine entities.

What if the lender says the OTP proves the loan is yours?

An OTP is evidence, but it is not always conclusive evidence.

A proper investigation should look at the entire transaction:

Who controlled the SIM at that time?
Was the SIM registered to you, transferred, replaced, or reissued?
What ID was uploaded?
Was the selfie genuine?
What device was used?
What IP address or location was recorded?
Where were the proceeds sent?
Did the borrower’s bank or e-wallet account match your verified account?
Were there prior suspicious attempts?
Did the lender follow proper KYC and fraud controls?

If the lender approved a loan based only on possession of a mobile number, despite obvious mismatch or weak verification, that may support your complaint.

What if collectors are harassing you or your contacts?

Collection is not unlimited. Even if a debt exists, collectors must use lawful and fair methods. If the debt is disputed because of identity theft, aggressive collection becomes even more problematic.

Document the following:

threats of arrest or imprisonment;
insults or defamatory messages;
threats to post your photo online;
messages to your relatives, employer, or contact list;
false statements that you are a criminal;
repeated calls at unreasonable hours;
collection despite written dispute;
refusal to identify the collection agency.

For SEC-regulated lending and financing companies, SEC Memorandum Circular No. 18, Series of 2019 prohibits unfair debt collection practices. Separately, the National Privacy Commission has warned against online lenders harvesting phone and social media contact lists for collection purposes.

Can you be arrested for not paying a loan you did not make?

No one should be arrested simply because a private lender claims you owe money. Non-payment of debt, by itself, is generally a civil matter. The Philippine Constitution prohibits imprisonment for debt.

However, fraud, falsification, cybercrime, or use of fake documents can be criminal. That is why you must be careful: your position should be clear that you are the victim of impersonation, not the person who committed the fraud.

If a collector says, “We will have you arrested today,” ask for the case number, court, prosecutor’s office, and copy of the complaint. Most abusive collectors cannot provide these because they are using fear to force payment.

Common mistakes to avoid

Paying “just to stop the harassment”

Paying can sometimes be interpreted as acknowledgment, especially if you do it without a written reservation. If you decide to pay for practical reasons, make sure your written communication says the account remains disputed and payment is not an admission. But in most identity theft cases, the better first move is to dispute, document, and escalate.

Only calling customer service

Phone calls are hard to prove. Always follow up by email or written ticket.

Ignoring the problem because “it is not mine”

Ignoring it can allow the false account to age into default, be sold to collectors, or appear in credit reports. Dispute early.

Giving more personal data to suspicious collectors

Before sending IDs, selfies, or signatures, verify that you are communicating with the actual lender or regulator. Scammers sometimes pretend to “help clear” fake loans to collect more data.

Posting everything publicly

Public posts may pressure companies, but they can also expose your personal data or complicate future complaints. Redact loan numbers, ID numbers, addresses, and private phone numbers.

Practical timelines

Step	Typical timing
Preserve evidence and send first dispute	Same day to 3 days
Lender internal review	Around 7 to 30 days, depending on company
Telco inquiry or SIM blocking/replacement	Same day to several days for basic assistance; longer for records
Police blotter	Usually same day
Cybercrime complaint preparation	Several days to weeks, depending on evidence
NPC complaint preparation	Often 1 to 3 weeks if affidavits and attachments are needed
CIC credit dispute	Depends on credit report access, TRN, and submitting entity response
Prosecutor complaint	Several weeks to months depending on docket, counter-affidavits, and evidence

These are practical estimates, not guaranteed deadlines. Bottlenecks usually happen when companies refuse to release verification records, when the app is not properly identified, or when the false loan was processed through multiple entities.

Frequently Asked Questions

Can a loan be valid if it was made using my old SIM card?

Not automatically. A valid loan still requires your consent. If someone else used an old SIM, OTP, ID, or fake account to impersonate you, you should formally dispute the loan and demand proof of application, verification, and disbursement.

What should I do first if I receive collection texts for a loan I never made?

Take screenshots, do not admit the debt, send a written dispute to the lender, ask for all loan records, contact your telco about the SIM, and file a blotter or cybercrime report if identity theft appears involved.

Is an OTP enough proof that I borrowed money?

An OTP may show access to a number, but it does not always prove that you personally borrowed. The lender should also verify identity, consent, application records, device information, and where the proceeds were sent.

Can I complain to the SEC about an online lending app?

Yes, if the lender is a lending company, financing company, or online lending platform under SEC supervision. Use SEC complaint channels and attach screenshots, your dispute letter, collection messages, and proof that the account is unauthorized.

Can I complain to the National Privacy Commission?

Yes, if your personal data was misused, processed without authority, disclosed to others, used for harassment, or not corrected despite your request. NPC complaints usually require a verified or notarized complaint and evidence.

What if the false loan appears on my credit report?

Dispute it with the lender and through the Credit Information Corporation’s Online Dispute Resolution Process. You will usually need a recent credit report and the TRN shown on it.

What if I am abroad and someone in the Philippines used my identity?

You can still dispute the account by email and file complaints with Philippine regulators where available. For sworn documents, use a Philippine Embassy or Consulate, or notarization and apostille procedures if applicable. You may also authorize someone in the Philippines through a Special Power of Attorney.

Can collectors contact my family or employer?

Collectors should not shame, threaten, or improperly disclose your personal data to third parties. If they contact relatives, employers, or your phone contacts about a disputed loan, document it and consider complaints with the SEC and NPC.

Should I change all my passwords and e-wallet PINs?

Yes. If an old SIM or number was involved, secure your email, banking apps, e-wallets, social media, and recovery numbers. Enable stronger authentication where possible and remove old mobile numbers from accounts.

Do I need a lawyer to dispute the loan?

Not always. Many disputes start with written complaints to the lender, SEC, BSP, NPC, CIC, telco, police, or NBI. But if the amount is large, your credit record is affected, collectors are harassing others, or a criminal complaint is being filed against you, legal assistance can be very helpful.

Key Takeaways

A loan opened under your name using an old SIM card is not automatically your legal obligation.
Under the Civil Code, a loan contract requires your consent.
An OTP sent to an old number is not always enough to prove that you borrowed.
Dispute the loan in writing, demand verification records, and ask the lender to suspend collection and credit reporting.
Preserve screenshots, call logs, emails, app notices, and proof about the SIM.
Report SIM, cybercrime, privacy, lending, and credit-report issues to the correct agencies.
Use the SEC for lending and financing companies, BSP for BSP-supervised financial institutions, NPC for data privacy violations, CIC for credit report disputes, and PNP/NBI for identity theft or cyber fraud.
Do not admit, restructure, or pay a disputed loan without carefully documenting that you deny liability.
The faster you create a paper trail, the easier it is to prove that you are a victim of impersonation, not the borrower.
