Thailand requires foreign tourist SIM registration with passport identity verification, limits registration to three numbers per person per operator, and limits tourist SIM use to 60 days unless identity is verified again for continued service.
Use a legitimate seller
Identity checks reduce anonymous and fraudulently registered SIMs. Use an operator or authorised registration channel and obtain a receipt. (NBTC tourist SIM safeguards)
Show the original only through the required process. Do not send passport images to an unknown chat seller or reuse an unsecured link.
| Situation | What changes |
|---|---|
| Buying at an operator shop | Present the original valid passport |
| Buying an eSIM before travel | Confirm how the operator completes required identity verification |
| Already has three numbers with one operator | Do not expect another registration with that operator |
| Need service beyond 60 days | Contact the operator for fresh identity verification |
Count by operator
The published limit is three numbers per person per mobile operator. Keep a record of active physical SIMs and eSIM profiles. (NBTC SIM identity registration update)
A tourist SIM cannot simply be extended indefinitely by topping up. Ask the operator about re-verification if the stay or use continues.
Example: A traveller with two active numbers from the same operator has one remaining registration slot under the three-number limit. A 70-day stay needs operator guidance before day 60.
Test essential services
Activate data, local calls, roaming and account recovery before leaving the counter. Keep the operator support channel and SIM identifier securely.
Remove an unused eSIM profile only after preserving any account or refund evidence. Check whether the operator requires cancellation or identity updates.
