Mobile coverage in Thailand
9 carriers support Roamgo eSIMs in Thailand. Tap any operator below to see their official coverage map.
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.
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.
