Thailand eSIM FAQ
Do I need an eSIM for Thailand?
You don't need one, but it saves significant money. Thai carriers charge 10–20 THB per MB for international roaming. A travel eSIM costs around $8 for 10–15GB — roughly 100× cheaper.
Which eSIM provider works best in Thailand?
Airalo offers dedicated Thailand plans using AIS and DTAC/True Move networks — both have strong coverage across Bangkok, Phuket, Chiang Mai, and the islands. Yesim also has reliable Thailand coverage.
Does eSIM work in Phuket, Koh Samui, or the islands?
Yes. AIS and DTAC have coverage across all major Thai islands. You'll get 4G LTE on most islands, with possible slowdowns in very remote coastal areas.
Can I use my eSIM from Bangkok to Bali on the same trip?
Yes — Airalo and Yesim offer regional Asia plans that cover both Thailand and Indonesia, ideal for multi-stop trips. No need to buy separate plans.
