eSIMs for Thailand
Pick how much high-speed data you want per day, then choose the duration that matches your trip.
About Thailand
Thai SIMs are cheap at the airport but the language barrier on AIS and TrueMove kiosks plus topup-machine quirks burn an easy hour. A roamgo eSIM lets you bypass all of it — install before you fly, activate when you land at BKK or Phuket International.
- Best for
- Bangkok layovers, beach hops between Phuket / Krabi / Koh Samui, food tours through Chiang Mai, and island connections to Phi Phi or Koh Lanta.
- Networks
- Roams onto AIS, TrueMove H, and DTAC. AIS has the strongest signal across the southern islands; TrueMove is often the fastest in central Bangkok.
- Travel tip
- Cellular coverage on ferry rides between mainland piers and the smaller islands (Koh Tao, Koh Yao) drops to nothing for 30-90 minutes — pre-download maps and messages.
