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.
