How we picked
We compared 10 GB for 30 days, plus unlimited options, the networks each eSIM uses, hotspot rules and refunds. Prices were read from each provider’s own Thailand page on October 19, 2026. Pelesim prices are shown before VAT; other prices are as each site displayed them, and local taxes may apply.
Coverage on the islands
Bangkok and the big resort towns have strong signal on every network. On smaller islands and ferries, coverage depends on which network the eSIM can use, so a plan that can switch between True, AIS and DTAC is the safer pick if you are island hopping.
Before you buy
Check that your phone supports eSIM and is carrier unlocked. Install the eSIM at home while you are online, then turn on the line and data roaming when you land. Keep your home SIM on for calls and SMS, since these plans are data only.
