The SIM Registration Act, officially Republic Act No. 11934, is a Philippine law that regulates the registration and use of Subscriber Identity Module (SIM) cards. President Ferdinand Marcos Jr. signed the law on October 10, 2022. RA 11934 requires SIM users to register their numbers with their telecommunications provider before activation. The law covers physical SIM cards, eSIMs, and SIMs used in mobile phones, broadband or Wi-Fi devices, and other electronic communication devices.
The law was created in response to the misuse of mobile communications for scams, fraudulent messages, phishing, and other unlawful activities. Its framework connects subscriber identity with a mobile number while setting rules for data confidentiality and lawful disclosure.
What Is the SIM Registration Act?
Republic Act No. 11934 is formally titled the Subscriber Identity Module (SIM) Registration Act.
Its central requirement is simple: a SIM must be registered with the relevant public telecommunications entity before activation.
For existing SIMs, the law also required registration within the period set by the Act. The original law provided 180 days from effectivity, with the Department of Information and Communications Technology (DICT) authorized to extend the period by up to 120 days. An existing SIM that remained unregistered after the applicable period was subject to automatic deactivation.
The law covers:
- Physical SIM cards
- Globe eSIMs
- Mobile phone SIMs
- Broadband and Wi-Fi SIMs
- Other SIM-based electronic communication devices
- Individual subscribers
- Foreign nationals
- Minors
- Corporate and other juridical end-users
The National Telecommunications Commission (NTC) issued the implementing rules through Memorandum Circular No. 001-12-2022.
Why Was RA 11934 Passed?
RA 11934 focuses on the misuse of mobile communication services.
Before SIM registration, a mobile number could be used without a registration framework connecting it to verified subscriber information. The law gives telecommunications and law-enforcement authorities a legal mechanism for identifying the subscriber connected with a number in certain investigations.
The law’s policy declaration links SIM regulation with efforts to address crimes involving electronic communications. The NTC also states that SIM registration aims to help authorities address mobile phishing, text spam, and similar crimes.
The law therefore has two major sides:
| Area | Purpose |
|---|---|
| Subscriber registration | Connect a SIM with verified subscriber information |
| Crime investigation | Provide a legal route for obtaining subscriber information |
| Fraud prevention | Reduce anonymous use of mobile numbers |
| Data protection | Restrict disclosure of registration information |
| SIM management | Establish rules for activation, deactivation, sale and transfer |
| Accountability | Create penalties for specified violations |
Who Is Covered by the SIM Registration Act?
The law applies to end-users of SIMs acquired in the Philippines.
The NTC states that coverage extends to:
- Filipino subscribers
- Foreign nationals
- Corporate users
- Business entities
- Juridical entities
- Mobile-device users
- Broadband or Wi-Fi device users
- Other users of electronic communication devices using SIMs
The law also expressly covers eSIMs.
This means SIM registration goes beyond ordinary mobile phone subscribers. A SIM used in a broadband device can also fall within the law.
What Does the Law Require From Telecommunications Companies?
Public telecommunications entities, or PTEs, have several duties under RA 11934.
A new SIM sold or issued by a PTE, agent, reseller, or other authorized entity must remain deactivated until the end-user completes registration.
The PTE must also maintain a SIM Register containing the information required by law. That database has a specific legal purpose: processing, activating, or deactivating SIMs and subscriptions.
The law also requires PTEs to provide reporting mechanisms for potentially fraudulent calls and messages. After proper investigation, the PTE may deactivate the SIM used for fraudulent communication.
What Is the SIM Register?
The SIM Register is the database maintained by each public telecommunications entity for registered subscriber information.
RA 11934 limits the use of this database. Its purpose centers on SIM and subscription administration rather than unrestricted use of subscriber data.
The law also requires PTEs to protect registration information and sets rules governing disclosure.
A successful submission and acceptance of the required Globe registration information serves as the subscriber’s certification of registration under the law.
How Does the Law Protect Subscriber Information?
Data privacy is a major part of the SIM Registration Act.
Registration information must be treated as confidential. A telecommunications provider cannot simply release subscriber information to any requester.
The law allows disclosure in specific circumstances, such as:
- A legal obligation under applicable law
- A court order or legal process based on probable cause
- A lawful request connected with an investigation covered by the Act
- Written consent from the subscriber
The Act also states that a waiver of confidentiality cannot be imposed as a condition for approving a subscription agreement.
Can Law Enforcement Obtain SIM Registration Information?
Yes, but RA 11934 establishes a legal process.
Under Section 10, a PTE must provide registration information upon the issuance of a subpoena by a competent authority in an investigation based on a sworn complaint involving a specific mobile number allegedly used for a crime or malicious, fraudulent, or unlawful act.
The complaint must also state that the identity of the alleged perpetrator cannot otherwise be established.
This means SIM registration does not create unrestricted access to subscriber records. The Act sets conditions for disclosure.
How Long Must SIM Registration Data Be Kept?
The law requires relevant registration data to remain with the telecommunications provider for 10 years after the subscriber’s mobile number is deactivated.
The IRR states that the retained information is for the purpose provided by the Act.
The retention requirement applies even after the SIM has been deactivated.
What Happens to a Lost or Stolen SIM?
RA 11934 addresses lost SIMs as part of subscriber obligations and SIM management.
The subscriber must report a lost or stolen SIM to the telecommunications provider. The IRR requires the report to provide information that can establish ownership of the number.
The Act also requires the concerned PTE to deactivate a reported lost or stolen SIM within 24 hours from the report, subject to the law’s provisions.
This rule reduces the period during which a lost number could remain active under the subscriber’s identity.
What Happens After a Subscriber Dies?
The law also addresses the death of an end-user.
The IRR directs immediate family members or relatives to report the death to the relevant telecommunications provider. The purpose is to allow the provider to take the appropriate action regarding the registered SIM.
Can a Registered SIM Be Sold or Transferred?
A registered SIM cannot simply be handed to another subscriber as an ordinary transfer.
Section 7 of RA 11934 requires the registration requirements to be followed for the subsequent sale or transfer of a registered SIM.
The IRR also places a direct obligation on end-users not to sell or transfer a registered SIM without complying with the required registration process.
This rule prevents a registered number from remaining tied to one identity while another person uses it.
Is Selling a Stolen SIM Illegal?
Yes.
RA 11934 makes the sale of stolen SIMs a criminal offense. The law also extends liability to PTEs, agents, resellers, or other entities that engage in the sale of stolen SIMs.
The penalty can reach:
- 6 months to 2 years imprisonment
- ₱100,000 to ₱300,000 fine
- Or both
For a corporation, partnership, or juridical entity, responsible officers may face liability under the conditions set by the law.
What Is SIM Spoofing Under RA 11934?
SIM spoofing refers to transmitting misleading or inaccurate information about the source of a phone call or text message with the intent to:
- Defraud
- Cause harm
- Wrongfully obtain something of value
The law treats spoofing as a separate offense. Authorized law-enforcement activities and caller-ID manipulation specifically allowed by a court order fall within the stated exceptions.
What Are the Penalties Under the SIM Registration Act?
RA 11934 establishes separate penalties for different violations.
| Violation | Penalty |
|---|---|
| False or fictitious registration information | 6 months–2 years imprisonment, or ₱100,000–₱300,000 fine, or both |
| Fraudulent identity or identification documents | 6 months–2 years imprisonment, or ₱100,000–₱300,000 fine, or both |
| SIM spoofing | At least 6 years imprisonment, or ₱200,000 fine, or both |
| Sale of a stolen SIM | 6 months–2 years imprisonment, or ₱100,000–₱300,000 fine, or both |
| Improper sale or transfer of a registered SIM | 6 months–6 years imprisonment, or ₱100,000–₱300,000 fine, or both |
| Intentional breach of subscriber confidentiality by a PTE or covered personnel | ₱500,000–₱4 million fine |
| Confidentiality breach caused by negligence | ₱500,000–₱4 million fine |
These penalties come from Section 11 of RA 11934 and the corresponding provisions of its implementing rules.
Penalties for False SIM Registration Information
Providing false or fictitious information during SIM registration carries criminal penalties.
The same provision covers the use of:
- A fictitious identity
- Fraudulent identification documents
- False registration information
The penalty is 6 months to 2 years imprisonment, a ₱100,000 to ₱300,000 fine, or both.
This provision makes truthful registration more than a telecom-company requirement; false information can create criminal liability.
Penalties for SIM Spoofing
SIM spoofing carries one of the strongest penalties listed in RA 11934.
A person who transmits misleading or inaccurate information about the source of a call or text with the prohibited intent may face:
- At least 6 years imprisonment
- A ₱200,000 fine
- Or both
The law provides exceptions for authorized law-enforcement activity and court-authorized caller-ID manipulation.
Penalties for Improper SIM Sale or Transfer
Selling or transferring a registered SIM without completing the required registration process is also punishable.
The penalty ranges from:
- 6 months to 6 years imprisonment
- ₱100,000 to ₱300,000 fine
- Or both
A person who assists or aids in an offense under the Act may also face liability as a co-principal.
Penalties for Telecommunications Companies
The law does not place all obligations on subscribers.
A PTE that refuses or fails to register a compliant SIM without a valid reason can face escalating fines:
| Offense | Fine |
|---|---|
| First offense | ₱100,000–₱300,000 |
| Second offense | ₱300,000–₱500,000 |
| Third and later offenses | ₱500,000–₱1,000,000 per offense |
The law also imposes fines of ₱500,000 to ₱4 million for certain confidentiality violations involving subscriber information.
What Role Does the NTC Have?
The National Telecommunications Commission (NTC) has a central regulatory role in the SIM Registration Act.
RA 11934 directs the NTC to establish guidelines for monitoring and proper implementation of the law in coordination with agencies such as DICT, the Department of Trade and Industry, the National Privacy Commission, telecommunications providers, and consumer groups.
The NTC subsequently issued Memorandum Circular No. 001-12-2022, the implementing rules and regulations for RA 11934.
What Role Does DICT Have?
The Department of Information and Communications Technology (DICT) has responsibilities tied to the implementation framework.
The original Act also gave DICT authority to extend the original registration period by up to 120 days.
The law further requires telecommunications providers to report a cyberattack against their SIM Register to DICT within 24 hours of detection.
What Are the Main Subscriber Obligations?
The implementing rules set several responsibilities for SIM users.
Subscribers must:
- Register their own SIMs.
- Provide truthful registration information.
- Report changes to registration information.
- Report a lost or stolen SIM.
- Report the death of an end-user through the appropriate family or relative.
- Request SIM activation or deactivation through the provider.
- Follow the legal process for transferring or selling a registered SIM.
These obligations appear in Rule III, Section 9 of the IRR.
Does the Law Apply to eSIMs?
Yes.
RA 11934 expressly states that its definition of SIM covers eSIMs and other variations. This gives the registration requirement a technology-neutral scope rather than limiting it to removable plastic SIM cards.
The same legal framework therefore applies to mobile numbers delivered through compatible eSIM technology.
What Does SIM Registration Mean for Existing Numbers?
The law created a registration requirement for existing SIM subscribers as well as new SIMs.
Existing subscribers had a registration period set by the Act. An existing SIM that remained unregistered after the applicable period was subject to automatic deactivation. The law also provided a route for reactivation after registration.
For new SIMs, activation depends on completion of registration.
Does SIM Registration Give the Government Automatic Access to Your Number?
No.
RA 11934 does not provide unrestricted access to subscriber information.
The law sets confidentiality protections and identifies specific circumstances for disclosure. For crime-related investigations covered by Section 10, disclosure requires a subpoena from a competent authority following the conditions stated in the law.
That distinction matters: registration creates a verified subscriber record, but access to that record remains subject to legal requirements.
How Does the SIM Registration Act Address Scam Messages?
The law gives PTEs reporting mechanisms for potentially fraudulent calls and messages.
After investigation, a telecommunications provider may deactivate a SIM used for fraudulent communication.
SIM registration also gives investigators a subscriber record that can assist a lawful investigation involving a mobile number.
The NTC has continued public education efforts against text scams and has linked SIM registration with broader anti-scam measures.
What Is the Difference Between SIM Registration and SIM Activation?
These terms describe two related but separate actions.
SIM registration records the subscriber’s identity and required information with the telecommunications provider.
SIM activation enables the SIM to receive telecommunications service.
RA 11934 makes registration a prerequisite for activation of a new SIM.
This structure means buying a SIM does not automatically give the buyer an active mobile service.

Final Takeaway
The SIM Registration Act is primarily a telecommunications regulation and public-safety law, not simply a procedure for uploading an ID and activating a phone number.
RA 11934 creates a legal identity framework for SIM users, establishes responsibilities for telecommunications providers, restricts access to registration data, sets rules for lost and transferred SIMs, and creates criminal penalties for fraudulent registration, spoofing, stolen SIM sales, and improper transfers.
For subscribers, the main legal duties are straightforward: register with accurate information, protect the registered number, report loss or changes, and follow the proper process for any transfer. For telecommunications providers, the Act adds duties involving registration, database security, confidentiality, reporting mechanisms, and lawful disclosure.
That gives the law a much broader purpose than the registration process alone: it establishes rules for who can use a SIM, how subscriber information is handled, how mobile numbers can be transferred, and what conduct can lead to criminal or financial penalties.
