Thailand has solid 4G coverage in cities and most tourist areas — AIS and DTAC are the main local networks. An eSIM on either gets you reliable data from Bangkok to Chiang Mai to Koh Samui without hunting for a SIM counter at the airport.

Coverage notes
All four providers use local Thai networks. Island coverage (Koh Samui, Koh Phangan, Koh Tao) is generally fine on AIS but can drop on the southern islands. If you're spending most of your time in Bangkok or Chiang Mai, any provider works. Remote northern trekking areas may have gaps regardless of provider.
