SIM Registration Law in the Philippines: RA 11934 Explained
A plain-language guide to who must register, what carriers may collect, the current activation rule, confidentiality, transfers and the penalties people often misstate.
Republic Act No. 11934 requires every end-user of a Philippine SIM to register with the serving public telecommunications entity before activation. It covers prepaid and postpaid service, physical SIMs, eSIMs, local and foreign users, individuals and organizations. New SIMs are sold deactivated, and the carrier must provide registration at no cost.
RA 11934 at a glance
| Question | What the law says |
|---|---|
| Who registers? | The end-user: an individual or juridical entity that buys or uses the SIM, including a local or foreign national. |
| What is covered? | Physical SIMs, eSIMs and electronic equivalents used in phones, computers, modems and other electronic devices. |
| Where is registration done? | With the serving carrier through its official electronic platform or authorized assisted channel. There is no single all-network government portal. |
| When is a new SIM activated? | Only after the end-user completes registration and the carrier accepts the required submission. |
| What does it cost? | The required registration process must be provided at no cost to the end-user. |
| Who keeps the record? | Each carrier maintains its own SIM Register and must secure it. |
| Can a registered SIM be transferred? | Only after complying with the registration requirements and the serving carrier’s authorized ownership process. |
For the practical registration route, use the all-network SIM registration guide. This article focuses on the law behind that process.
Who and what the Act covers
The Act defines an end-user broadly. It is not limited to the person holding a prepaid phone. Coverage includes:
- Filipino and foreign individual subscribers.
- Companies, partnerships, government offices and other juridical entities.
- Prepaid and postpaid subscriptions.
- Physical SIM cards, eSIMs and other electronic variations.
- SIMs used in mobile phones, tablets, computers, pocket WiFi and fixed wireless modems.
The final NTC implementing rules also address data-only, fixed wireless broadband, machine-to-machine and Internet of Things uses. A SIM is not outside the framework simply because it is installed in a modem rather than a phone.
Information and documents required by law
| Registrant | Core legal requirements |
|---|---|
| Filipino adult | Full name, date of birth, sex, address, assigned mobile number and SIM serial information, a declaration of accuracy, and valid government-issued photo identification or a similar qualifying document. |
| Minor | The parent or guardian registers the SIM under that adult’s name, gives consent and provides the required identity evidence. |
| Foreign tourist | Full name, nationality, passport number, Philippine address, passport, proof of Philippine address and a return or onward ticket. Tourist registration is temporarily valid for 30 days. |
| Other foreign national | Passport and Philippine address evidence plus the applicable ACR I-Card, Alien Employment Permit, school registration/ID or other pertinent document. |
| Corporation | Certificate of registration and a duly adopted resolution naming the authorized representative. |
| Other juridical entity | Certificate of registration and a Special Power of Attorney for the authorized representative, as applicable. |
Carriers may use identity-verification measures such as an ID image, OCR or selfie, subject to privacy law. Their current form decides which supported document format can be processed. See all registration requirements and the accepted-ID guide.
What carriers must do
- Maintain their own SIM Register. The statutory database is held by each public telecommunications entity, not by an independent guide site.
- Limit the register’s purpose. The law says the database is for processing, activating or deactivating a SIM or subscription, except where another provision of law permits processing or disclosure.
- Secure subscriber data. Carriers must protect the information at all times and meet DICT information-security standards consistent with relevant law and internationally accepted cybersecurity standards.
- Provide free registration. The required carrier registration cannot carry an end-user processing fee.
- Record reported changes. A carrier must clearly note an end-user information change in its database.
- Provide fraud-reporting mechanisms. Carriers must provide user-friendly ways for customers to report potentially fraudulent texts or calls and investigate the reported SIM.
What an end-user must do
Register with truthful information
Use the correct identity and genuine documents. Review OCR-filled fields before making the required declaration.
Protect the verification process
Submit the number, OTP, ID and selfie only through the verified carrier platform or authorized assisted channel.
Report a change promptly
Tell the carrier when registered information changes. Use its formal correction route rather than creating a second conflicting record.
Report loss, death or requested deactivation
The end-user should report loss; immediate family, relatives or a guardian may report a death. Preserve the carrier’s case or acknowledgment.
Use the ownership-transfer process
Do not hand over or sell an already registered SIM as if possession alone changed the named subscriber. Start with the SIM ownership-transfer guide.
Confidentiality, disclosure and retention
Section 9 treats information obtained during registration as confidential. The protection is strong, but it is not a promise that the data can never be lawfully disclosed.
- Full name and address may be disclosed when another law requires it consistently with the Data Privacy Act.
- Disclosure may occur under a court order or legal process based on probable cause.
- Section 10 requires carrier disclosure in response to a subpoena from a competent authority in the investigation described by that section.
- A subscriber may provide written consent, but waiver of confidentiality cannot be made a condition for approving the subscription.
The carrier must retain relevant registration data for ten years from deactivation of the mobile number. That statutory duty can limit a request for immediate erasure. Optional marketing consent is separate from the registration requirement. Read what happens to SIM registration data for the full privacy explanation.
Sale, transfer and stolen SIMs
Section 7 does not ban every legitimate ownership change. It prohibits selling or transferring a registered SIM without completing the required registration. Section 8 separately makes the sale of stolen SIMs an offense for covered sellers and entities.
| Situation | Legal distinction |
|---|---|
| Buying a new inactive SIM | Permitted through a legitimate seller; the end-user registers it with the carrier before activation. |
| Handing over a used registered SIM | Possession is not enough. The parties must follow the carrier’s identity and ownership-change process. |
| Buying a ready-to-use pre-registered SIM | High risk and potentially within the prohibited sale/transfer rule. See the pre-registered SIM warning. |
| Replacing a lost or damaged SIM | A carrier replacement for the verified subscriber is not an informal sale; use the official replacement channel. |
| Changing networks but keeping the number | Mobile Number Portability is a separate carrier process and may require registration with the receiving network. |
Penalties stated in RA 11934
| Offense described by the Act | Statutory penalty |
|---|---|
| Carrier failure or refusal to register without valid reason despite end-user compliance | Escalating carrier fines: ₱100,000-₱300,000 for a first offense; ₱300,000-₱500,000 for a second; ₱500,000-₱1,000,000 for each later offense. |
| Carrier/agent/employee breach of registration confidentiality, including through negligence | ₱500,000-₱4,000,000. |
| False or fictitious registration information or fraudulent identity documents | Six months to two years’ imprisonment, ₱100,000-₱300,000 fine, or both. |
| Spoofing as defined by the Act | At least six years’ imprisonment, a ₱200,000 fine, or both, subject to the statute’s law-enforcement and court-order exceptions. |
| Sale of a stolen SIM by a covered PTE, agent, reseller or entity | Six months to two years’ imprisonment, ₱100,000-₱300,000 fine, or both. |
| Sale or transfer of a registered SIM without required registration | Six months to six years’ imprisonment, ₱100,000-₱300,000 fine, or both. |
Current rule versus the 2023 transition
The Act originally gave subscribers with SIMs already in circulation a transition window, which DICT extended within the authority granted by law. That nationwide transition ended in 2023. The stable current rule is simpler: a newly issued SIM is deactivated until registration is completed.
- Do not publish the old transition deadline as a current annual deadline.
- Do not describe the former grace arrangements as a permanent reactivation right.
- Do not promise that a legacy number deactivated in 2023 can still be recovered.
- Registration does not prevent a prepaid SIM from later expiring under normal inactivity or account rules.
Common misconceptions
| Claim | Accurate explanation |
|---|---|
| “NTC has one registration website” | False. Each carrier operates its own registration platform. |
| “One person may register only a fixed number of SIMs” | RA 11934 states no numeric personal ownership limit; every SIM still needs an accurate record. |
| “eSIM is exempt” | False. The Act expressly includes eSIMs. |
| “A minor registers under the minor’s own name” | False under the Act’s registration rule; the parent or guardian registers under that adult’s name. |
| “Registration data can never be disclosed” | Confidentiality has narrow statutory exceptions, including specified legal process and subscriber consent. |
| “A buyer owns a registered SIM once money changes hands” | False. The required registration and carrier ownership process must be completed. |
Frequently asked questions
Is SIM registration still a law in 2026?
Yes. RA 11934 remains the governing statute reviewed for this article. New Philippine SIMs must be registered before activation.
Does the law cover eSIMs and WiFi SIMs?
Yes. The Act expressly includes eSIMs and electronic equivalents; the NTC rules also address broadband modem and data-only uses.
Does the government keep one central SIM database?
RA 11934 requires each public telecommunications entity to maintain its own SIM Register. It does not create one public all-network consumer registration portal.
How many SIMs can one person register?
The Act states no numeric limit. Each SIM must still be registered truthfully and remain subject to carrier account rules.
Can registration data be given to law enforcement?
Only through the circumstances and legal process specified by Sections 9 and 10 or another applicable law. Registration does not make the database publicly searchable.
How long is registration data retained?
The Act requires relevant information to be retained for ten years from deactivation of the mobile number.
Is selling a registered SIM always illegal?
A legitimate transfer may be possible, but the sale or transfer cannot bypass the required registration and carrier ownership process.
Where can I complain about a carrier registration problem?
Start with the carrier and retain its case reference. An unresolved telecommunications-service complaint can be submitted through NTC’s official route; use the NTC complaint guide.
