Deactivating a Lost DITO SIM Card in the Philippines
A comprehensive legal guide for subscribers, lawyers, and compliance officers
1. Why immediate deactivation matters
Losing a SIM card is no longer a mere inconvenience. Under Republic Act No. 11934 (2022), the SIM Registration Act, every SIM in the Philippines is tied to its owner’s verified identity. A lost SIM therefore exposes its registrant to:
| Risk | Typical scenario | Potential liability |
|---|---|---|
| Identity-based crimes | Scammer uses your number for phishing or extortion | Criminal investigation can initially point to you |
| Unauthorized financial transactions | One-time passwords (OTPs) for e-wallets/banks intercepted | Possible civil liability for negligence |
| Data-privacy breach | Personal messages, cloud log-ins, MFA codes exposed | Administrative fines under the Data Privacy Act (RA 10173) |
Timely deactivation is both a statutory duty and a practical shield against these risks.
2. Legal framework
SIM Registration Act (RA 11934)
- Sec. 6(b) – The subscriber “shall report any loss or theft immediately” to the Public Telecommunication Entity (PTE).
- Sec. 6(c) – The PTE must deactivate the SIM within 24 hours of receiving a valid loss report.
- Sec. 18(b) – Failure to report, if it leads to a crime, may be considered contributory negligence.
Implementing Rules and Regulations (IRR), Joint Memorandum Circular No. 001-2022
Rule 6.5 – The report may be made through a hotline, e-mail, walk-in, or the official app.
Rule 6.6 – The subscriber must present either:
- The SIM’s mobile number plus any one government-issued ID; or
- An Affidavit of Loss if personal ID cannot be validated remotely.
Rule 6.7 – Upon request, the PTE shall issue a replacement SIM retaining the same number, subject to standard fees.
National Telecommunications Commission (NTC) Memorandum Circular 03-03-2005 (still subsisting)
- Requires PTEs to honor blocking requests “without unreasonable delay” when the device itself (handset) is stolen.
Data Privacy Act (RA 10173) & NPC Advisory 2017-01
- A lost SIM containing personal data constitutes a security incident. Reporting to the National Privacy Commission is mandatory within 72 hours if there is a serious risk of harm.

4. Step-by-step guide for subscribers
Secure accounts first (within 15 minutes).
- Change passwords on online banking, e-wallets, social media.
- Disable SMS-based 2FA where possible.
Gather documentation (within 1 hour).
- A clear photo or scan of a valid government ID.
- Mobile number of the lost SIM.
- Optional but advisable: Police blotter or Affidavit of Loss.
Report to DITO (within 24 hours).
- Use the DITO app or hotline 185.
- Get the Ticket/Reference Number—this is your proof of compliance under RA 11934.
Check status.
- A deactivation SMS/e-mail confirmation will be sent to your alternate contact.
- If no confirmation after 24 hours, escalate to DITO Corporate Security corpsecurity@dito.ph or NTC Consumer Welfare Division (02-8924-4010).
Request replacement SIM (optional).
- Visit a DITO Experience Store with your ID and the reference number.
- The old SIM is permanently blocked; a new, pre-activated card is issued.
- Update banks and digital wallets with the new SIM immediately.
5. What if you recover the SIM after deactivation?
Reactivation is allowed only once per SIM under DITO policy (§ 8, SIM Replacement Guidelines 2024).
File a written request at a DITO Store with:
- Original SIM (physical card)
- Two valid IDs
- Affidavit of Recovery
Processing time: up to three (3) working days.
If 30 days have lapsed since deactivation, the number is quarantined and may be reassigned after 90 days.
6. Liabilities and penalties
| Omission | Statutory / regulatory penalty |
|---|---|
| Failure to report lost SIM | Fine up to ₱5,000 (RA 11934, Sec. 20) |
| False report (e.g., to avoid unpaid bills) | Fine up to ₱300,000 or imprisonment up to 6 months |
| Use of lost SIM in a crime | Separate prosecution; original owner may be held civilly liable if negligent |
| Disclosure of another person’s personal data via the lost SIM | Up to ₱5 million and imprisonment (RA 10173) |
7. Tips for preventive compliance
- eSIM as fallback. DITO has begun limited eSIM rollout; having an eSIM on a second device allows you to maintain service while resolving the loss.
- Disable SMS-only 2FA. Opt for authenticator apps.
- Label and secure physical SIM trays. Most thefts occur when phones are unattended in cafés and public transport.
- Use device-level locks. Face ID or fingerprint reduces immediate access to the Messages app.
- Maintain a record. Keep the SIM serial (ICCID) and purchase receipt in a secure cloud vault.
8. Frequently asked questions (FAQs)
| Question | Short answer |
|---|---|
| Can I report the loss through a representative? | Yes, with a Special Power of Attorney and both parties’ IDs. |
| Will I lose my load balance? | Your balance transfers to the replacement SIM if you request it within 15 days. |
| Is a police report mandatory? | Not under the SIM Act, but required by DITO if you request fee waiver or suspect criminal use. |
| How long before my number gets recycled? | Ninety (90) days after deactivation if no replacement request is filed. |
9. Key takeaways
- Report within 24 hours—this is both a legal obligation and your best defense against identity-based crimes.
- Keep a proof of report; it absolves you of liability for acts committed with the lost SIM after deactivation.
- Replacement is inexpensive and quick—do not delay if the number is linked to banking or work accounts.
- For companies issuing corporate DITO SIMs, integrate a Lost-SIM SOP aligned with RA 11934 and the Data Privacy Act in your information-security manual.
