The National Broadcasting and Telecommunications Commission (NBTC) has mandated that mobile phone users in Thailand must update their SIM card registration information by August 30, 2026.
According to Khaosod Thai, the telecom regulator has instructed all mobile service providers to complete this nationwide data update by the end of the month. The directive is part of a broader government crackdown on technology-related crimes, targeting unregistered SIM cards often used in scams.
What this means for you
If you live in Thailand and use a local SIM card, you need to ensure your identification details are accurately linked to your phone number before the August 30 deadline.
While the brief NBTC announcement does not explicitly detail the penalties for missing the deadline, previous SIM registration drives in Thailand have resulted in unverified numbers being suspended. Losing access to your Thai phone number can immediately lock you out of local banking apps and services that rely on SMS verification.
How to ensure your number remains active:
- Watch for SMS alerts: Mobile operators typically send text messages to users whose registration data is incomplete or outdated.
- Contact your provider: Check with your carrier (such as AIS, True, or Dtac) via their official app, USSD codes, or at a physical branch to confirm your registration status.
- Update expired documents: If you registered your SIM card with a passport that has since expired, you may need to present your current passport to your provider to update their records.
With the deadline approaching rapidly, expats should proactively confirm their SIM registration status rather than risking service disruption.
