1. Registration

   Thai SIM activation requires identity registration. Travellers should use their original passport and buy through an operator or authorised point of sale. Do not give a passport copy to an unverified reseller.

2. eSIM or physical SIM

   Confirm that the phone is unlocked and eSIM-compatible before purchase. Keep access to the operator account and activation instructions until the line works.

3. Longer stays

   Tourist packs are not automatically the best long-term option. Compare prepaid renewals and postpaid eligibility directly with the operator after confirming address and identity requirements.
