Bangkok, Thailand – August 21st, 2025 – In a move to curb the escalating threat of online fraud, the Thai government has introduced stringent SIM card registration measures aimed at tackling SIM-swap scams that have increasingly targeted unsuspecting citizens. The announcement, made by Deputy Government Spokesman Anukool Pruksanusak, is part of the government’s commitment to enhancing digital security as cybercriminals exploit vulnerabilities in mobile networks to perpetrate financial crimes.
The National Broadcasting and Telecommunications Commission (NBTC) will enforce the new regulations, effective immediately as of August 18th, 2025. These measures mandate the use of advanced Liveness Detection technology for all new mobile subscribers, covering both prepaid and post-paid plans, as well as existing users replacing SIM cards while retaining their phone numbers. It does not affect current users not changing anything.
The technology, akin to facial recognition systems used in banking applications, verifies identities in real time to prevent fraudsters from using photos, videos, or 3D masks to impersonate legitimate users. This addresses a critical loophole that previously allowed scammers to fraudulently register SIM cards.
“Online fraud, particularly SIM-swap scams, has caused significant financial and personal harm to victims,” said Anukool. “By implementing Liveness Detection, we aim to ensure that SIM card registrations are secure and verifiable, making it harder for criminals to exploit the system.” Under the new rules, mobile users must register their SIM cards in person at service centers, authorized dealers, retail outlets, or through secure applications provided by mobile operators.
SIM-swap scams, a growing global concern, involve fraudsters impersonating victims to trick mobile carriers into transferring a victim’s phone number to a SIM card under the scammer’s control. Once successful, criminals can intercept text messages and calls, including one-time passwords (OTPs) used for two-factor authentication, granting them access to bank accounts, social media profiles, and other sensitive platforms. In Thailand, recent high-profile cases have highlighted the devastating impact of these scams, with victims losing substantial sums to fraudsters who exploit weaknesses in SMS-based authentication.
The NBTC’s initiative aligns with global efforts to combat SIM-swap fraud. For instance, the U.S. Federal Communications Commission (FCC) adopted rules in 2023 requiring wireless providers to implement secure authentication methods and notify customers of SIM change requests. Similarly, India’s Department of Telecommunications has employed AI-based systems to detect and deactivate millions of fraudulent SIMs linked to cybercrimes. Thailand’s adoption of Liveness Detection positions it at the forefront of these efforts, leveraging cutting-edge technology to protect consumers.
Telecom operators in Thailand have been directed to comply with the new regulations, ensuring that all registration processes incorporate the Liveness Detection system. Customers are also encouraged to remain vigilant, monitor their accounts for suspicious activity, and report any unauthorized SIM changes immediately. The NBTC has also said that these measures will not only deter fraudsters but also enhance public trust in digital transactions, which are increasingly central to Thailand’s economy.
As the government rolls out these regulations, experts urge consumers to adopt additional safeguards, such as using authentication apps like Google Authenticator instead of SMS-based two-factor authentication and setting up unique PINs with their mobile carriers to lock their SIMs. “While these new measures are a step forward, individuals must also take proactive steps to protect their digital identities,” said cybersecurity analyst Dr. Supachai Wong. “Awareness and security practices are critical in this evolving threat landscape.”
The Thai government’s crackdown on SIM-swap scams reflects a broader regional push to address cybercrime, with countries like the Philippines and India also tightening SIM registration protocols. As online fraud continues to evolve, Thailand’s adoption of advanced technology signals a proactive stance in safeguarding its citizens’ financial and personal security.
For those concerned about potential SIM-swap fraud, the NBTC advises contacting mobile providers immediately if unusual account activity is detected, such as loss of network connectivity or unexpected notifications about SIM changes. With these stricter measures in place, Thailand aims to stay one step ahead of cybercriminals, ensuring a safer digital future for all.
