Thailand is one of the easiest places in the world to stay connected — if you skip roaming. From the temples of Bangkok to the beaches of Phuket and Krabi, a Thailand travel eSIM gives you instant data for maps, Grab rides, translation and booking island ferries, without your carrier's $10–15/day roaming charges.
Why use an eSIM in Thailand?
A Wanderly eSIM starts at $1.99 and installs in about two minutes — no airport SIM queue, no passport registration, no swapping your physical SIM. You activate it the moment you land at Suvarnabhumi or Don Mueang and you're online.

Thailand is one of our best-value destinations: 14 plans from $1.99, with data as low as $0.26/GB and sizes up to 50GB. See live options on our Thailand eSIM page or compare on the pricing page.
Coverage in Bangkok, Chiang Mai, Phuket & the islands
Expect fast 4G/5G in Bangkok, Chiang Mai, Pattaya and Phuket, and solid coverage on Koh Samui, Koh Phangan and Krabi. Because Wanderly aggregates multiple carriers, you're matched to strong local networks island to island.
