SIM & IMEI Blocking for Stolen Phones in the Philippines
(Updated as of 16 June 2025)
1. Why blocking matters
Stolen handsets are a gateway to identity theft, SMS-based fraud, mobile banking take-overs, and even “SIM-swap” attacks on one-time-password systems. Philippine regulators therefore require two distinct counter-measures the moment a phone goes missing:
| Measure | What it disables | Legal basis | Who initiates |
|---|---|---|---|
| SIM block / permanent de-activation | The subscriber identity and the mobile number (voice/SMS/data) | Republic Act No. 11934 (SIM Registration Act), §§ 6, 9 & IRR Rule 10 | The subscriber, via the mobile network operator (MNO) |
| IMEI block / blacklisting | The physical handset itself on all Philippine networks | NTC Memorandum Order 01-05-2004 (and 03-12-2012 amendments) | The subscriber or the MNO, filed with the National Telecommunications Commission |
Both processes are free of charge under current rules; penalties for non-compliance fall on the telcos and on anyone caught using a blocked device.
2. Governing statutes, regulations & circulars
| Instrument | Key provisions relevant to stolen devices |
|---|---|
| Republic Act 11934 (SIM Registration Act, 2022) and its 2023 Implementing Rules and Regulations (IRR) | • Mandatory SIM registration; • § 9: subscribers must report a lost or stolen SIM within 24 hours; • MNO must permanently deactivate the SIM and register that status in its database within 24 hours of report; • Free replacement SIM after identity verification. |
| NTC Memorandum Order 01-05-2004 (“Guidelines on Mobile Phone ‘Block-Off’”) | • MNOs must operate an Equipment Identity Register (EIR) and share daily updates; • IMEI must be blocked within 24 hours of receiving a verified request; • Blacklist is federated across all Philippine networks and uploaded to the GSMA Global Blacklist; • P 200 000 administrative fine per handset for failure to block. |
| Data Privacy Act of 2012 (RA 10173) | Governs handling of personal data (ID pictures, police reports) supplied in block requests. |
| Revised Penal Code, Arts. 308–311 | Theft/robbery charges for the taker. |
| Access Devices Regulation Act (RA 8484) | Criminalises fraudulent use of stolen SIMs in financial transactions. |
| Cybercrime Prevention Act (RA 10175) | Adds penalties if stolen SIM/IMEI is used for cyber-offences (e.g., phishing, online banking fraud). |
Pending bills. Congress has, since 2016, repeatedly revived versions of an “Anti-Mobile Device Theft Act” that would criminalise possession of a re-programmed IMEI. As of June 2025 none has passed the Senate.
3. Step-by-step blocking procedure
Tip: Before loss occurs, dial
*#06#and write down your 15-digit IMEI; keep a photo/scan of the sales receipt and a valid ID.
| Step | What to do | Typical proofs you’ll be asked for |
|---|---|---|
| 1. Call your carrier immediately (Smart, Globe, DITO, GOMO, TM, etc.) | • Hotline or in-app chat; • State you are invoking § 9 of RA 11934 for SIM blocking; • Request issuance of an incident reference number. |
• Full name & birthdate (must match SIM Registration); • Government ID; • Mobile number & last load amount/call made. |
| 2. Request IMEI block | Options: • (a) Via the same carrier—some telcos forward the request to NTC; • (b) File direct with NTC Consumer Welfare & Protection Division (Quezon City, regional offices, or online One-Stop Public Assistance Center). |
• Police blotter (or Barangay Incident Report) < 24 h old; • Proof of ownership (official receipt, delivery waybill, or sworn affidavit if lost); • The incident reference number from Step 1; • Accomplished NTC Form CWS-01. |
| 3. Track status | • Telco must confirm SIM de-activation within 24 h by SMS/email; • NTC issues a Certificate of IMEI Blacklisting (PDF or hard copy) within 2–3 working days. |
Keep this certificate—your bank, insurer, or e-wallet may ask for it. |
| 4. Replacement SIM & number retention | • Present the Certificate or reference number at any telco store; • The replacement SIM inherits your old number but not the old registration; you must sign a new SIM-Reg form on-site. |
– |
| 5. If your phone is recovered | • File a Petition to Remove from Blacklist (NTC Form CWS-02) attaching proof of recovery (e.g., PNP Property Acknowledgment Receipt); • Telco will re-activate after NTC lifts the block (up to 48 h). |

4. Timelines & penalties at a glance
| Action | Deadline | Responsible party | Penalty for delay/failure |
|---|---|---|---|
| Subscriber reports SIM loss | Within 24 h of discovery | Subscriber | Up to P 35 000 fine (SIM-Reg Act IRR) if failure facilitates a crime |
| Telco de-activates SIM | Within 24 h of report | MNO | P 100 000 – P 1 000 000 per incident (§ 10, RA 11934) |
| Telco/NTC blocks IMEI | Within 24 h of verified request | MNO + NTC | P 200 000 per handset (NTC MO 01-05-2004) |
| Person caught using blocked SIM/IMEI | – | Offender | 6 mos – 2 yrs prison + P 100 000 fine (§ 11, RA 11934); plus theft charges |
5. Frequently-asked legal questions
| Question | Short answer |
|---|---|
| Can I track the thief using the IMEI? | Only law-enforcement can request geo-location pings under a subpoena or court warrant (see § 8, Cybercrime Law); civilians must rely on Find-My-Device-type apps activated before the loss. |
| Is the block world-wide? | Philippine carriers upload blacklisted IMEIs to the GSMA global database. Compliance abroad varies: major networks in 60 + jurisdictions honor it, but gray-market unlocking in non-participating countries is still possible. |
| Will a dual-SIM phone be half-usable? | No. When the IMEI is blacklisted the entire baseband is disabled, so both SIM slots become unusable for cellular service. |
| Can I block a phone bought second-hand without papers? | Yes, but you’ll sign an Affidavit of Ownership & Loss; the NTC may require testimony that the seller has been notified and is not contesting the claim. |
| Does insurance require IMEI blocking? | Most local gadget-protect policies and some bank credit-card “purchase protection” riders insist on the NTC Certificate within 10–15 days of loss. |
6. Practical compliance checklist (print-this-out version)
- Before loss ☐ Record IMEI (§ 1). ☐ Keep purchase receipt & ID scan in cloud drive.
- Within 24 h after loss ☐ Call telco → get incident ref. no. ☐ File police blotter. ☐ Submit NTC Form CWS-01 (+ documents).
- Follow-up ☐ Confirm SIM blocked (SMS/email). ☐ Collect NTC Certificate. ☐ Process insurance/replacement SIM.
7. Final notes for practitioners
- Data privacy: Telcos are personal-information controllers; ensure consent language in SIM-Reg forms covers transmission to NTC and GSMA.
- Corporate-owned devices: Companies may block under a board resolution or secretary’s certificate; some MNO enterprise portals allow bulk blocking.
- Bring-Your-Own-Device (BYOD) fleets: HR policies should mirror the statutory 24-hour window; automatic MDM wipe does not satisfy legal reporting duties.
- Future changes: The DICT’s draft National Mobile Device Management Framework (2025) proposes an automated API so consumer apps can trigger a “kill-switch” that pushes straight into the NTC blacklist—watch for a new Memorandum Order by Q4 2025.
