Thailand tightens SIM card rules to combat scam
Thailand is tightening regulations on bulk SIM card purchases to combat scams, following the seizure of 200,000 SIM cards linked to a Chinese call center gang.

Authorities in Thailand are taking steps to regulate bulk SIM card purchases to combat their misuse in scams targeting Thai citizens. The issue came to light following the police seizure of 200,000 prepaid SIM cards linked to a Chinese call center gang.
Currently, there are no restrictions on corporate bulk SIM purchases, aside from a rule requiring registration for users holding more than five numbers. The lack of oversight has enabled SIM cards to be used illegally, particularly near borders where foreign SIMs are common.
Many of these cards are intentionally registered without clear user identities or are misused in IoT devices, GPS trackers, or sold to tourists. To address these gaps, the Ministry of Digital Economy and Society has proposed legal reforms requiring mobile operators and banks to verify buyer identities and notify users of suspicious transactions.
Additionally, stricter regulations on SMS messages with embedded links are set to take effect next year. Inspired by policies in countries like Singapore and Australia, these reforms aim to enhance accountability and curb abuse.
The National Broadcasting and Telecommunications Commission (NBTC) emphasises a gradual approach to implementing these measures to minimise inconvenience for consumers and avoid disrupting legitimate business operations. While tackling the misuse of SIM cards, authorities aim to strike a balance between protecting the public and ensuring businesses can operate smoothly. This measured approach reflects the broader goal of preventing scams while maintaining economic and social stability.
