Roaming vs eSIM in Thailand: cost comparison
Roaming your home carrier in Thailand costs significantly more than a local eSIM.
US carrier roaming in Thailand can cost $10–15/day. EU carriers often charge €0.02–0.10/MB outside the EU — a 1 GB video call can cost €20–100.
AIS tourist SIM cards at Suvarnabhumi Airport cost $8–15 for 15–30 GB. The trade-off is a 20-minute airport queue and passport registration. An LTE.app eSIM for Thailand on AIS or True Move is comparable in price with zero queuing and your home SIM stays active.
