Thailand's networks are AIS, True (which merged with DTAC) and NT. Coverage across Bangkok, the islands and main tourist routes is good.
Fixed-data travel eSIMs for Thailand start at a few dollars in our data, and unlimited plans cost more. Tourist SIMs sold at the airport are an alternative if you don't mind the queue and passport registration.

Travel eSIM or airport tourist SIM?
Tourist SIMs at Bangkok's airports are popular, but you'll queue on arrival and need your passport. A travel eSIM works the moment you land and keeps your physical SIM slot free.

Not always. Airport tourist SIMs can be competitive; the eSIM's advantage is that it works on landing with no queue.
