Bangkok eSIM plans
Suvarnabhumi handles most long-haul arrivals, Don Mueang the low-cost flights, and both have the Airport Rail Link or a Grab into town. With the eSIM on before immigration, Grab is booked by the time you have your bag. Bangkok has full 5G on AIS and TrueMove H across the city.
The cheapest Bangkok eSIM is $1.10 for 500 MB · 7 days; unlimited data costs $1.38 a day (the first 500 MB each day at high speed, then 512 Kbps under the fair use policy). Plans run on TrueMove H, DTAC, AIS and more, with 5G. Prices checked 9 November 2026.

Where you will use it
Around Bangkok
Full coverage in Sukhumvit, Silom, Khao San Road, Riverside, Chatuchak on every plan.
- Grab is cheaper and clearer than haggling with a taxi; it needs data for the pick-up point at the airport.
- The BTS and MRT are the fast way across town; the ViaBus app and Google Maps show live arrivals.
- For a trip that goes on to the islands, pick an AIS plan: it reaches furthest on Koh Samui and the Andaman coast.

Bangkok eSIM questions
How much does an eSIM for Bangkok cost?
Plans start at $1.10 for 500 MB · 7 days. Unlimited daily data costs $1.38 a day (the first 500 MB each day at high speed, then 512 Kbps under the fair use policy). Prices are in US dollars and include everything: no roaming fees, no subscription.
Does the eSIM work at both Bangkok airports?
Yes. Suvarnabhumi and Don Mueang are both covered on every Thai operator, including the arrivals halls and the Airport Rail Link, so the plan connects as soon as you switch the line on.
Will it work on the way to Chiang Mai and the islands?
A Thailand plan covers the whole country, including the overnight train north and the ferries near shore. Expect a weaker signal at sea between islands and in the hills of the north.
