eSIM for Thailand. eSIM for Thailand: AIS and TrueMove H coverage, what a local SIM really costs, and how to keep your own number live in Bangkok. No roaming bill.
Thailand is served by AIS, TrueMove H, dtac. 5G across Bangkok, Chiang Mai, Pattaya and Phuket town. Solid LTE on the mainland including the northern loop, with thinner coverage on the smaller islands and in the national parks.
Airport kiosks at Suvarnabhumi and Phuket sell tourist SIMs in minutes with a passport scan. The catch is the shape of the trip: most visitors move between the mainland, the Andaman islands and the Gulf islands, and a cheap plan bought for one region often throttles hard once you leave the city.
Bangkok and Chiang Mai are genuinely excellent. The Gulf islands are not the same network experience. Koh Tao, Koh Phangan and the smaller Andaman islands drop to congested LTE in high season, and ferry crossings lose service in the middle.
Thailand sits in the expensive tier for most European carriers. UK and EU plans that roam free inside the EU almost never include Thailand, and out-of-bundle rates of several pounds per megabyte are still common.
The alternative to both: Ringo is a global eSIM subscription that ports your existing phone number, so calls, SMS and two-factor codes keep working in Thailand and 180+ other countries on one flat monthly plan.
For a local SIM, yes. Thailand requires identity registration for every prepaid line, so airport and 7-Eleven purchases involve a passport scan. An eSIM you activate before you fly skips that step entirely.
Partially. You will hold service leaving Surat Thani and picking up again near the island, with a dead stretch in open water. Download anything you need before boarding.
Chiang Mai and Bangkok are among the best-connected cities in Southeast Asia for remote work, with fiber in most condos and coworking spaces. Our Thailand nomad guide covers the DTV visa and the real monthly cost.
