Chiang Mai eSIM plans
Chiang Mai’s airport is ten minutes from the Old City, so most visitors are in a Grab within half an hour of landing, with the Thailand plan already connected at the gate. The city is the base for the northern hills, cooking classes, night markets and the Sunday walking street, and the same eSIM covers the drive to Pai or Chiang Rai.
The cheapest Chiang Mai 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 Chiang Mai
Full coverage in Old City, Nimmanhaemin, Night Bazaar, Doi Suthep, Mae Rim on every plan.
- Grab and Bolt are the easiest way around; red songthaews are cheaper but need a little Thai or a map to point at.
- AIS reaches furthest into the hills north of the city; a dtac plan is fine in town and on the Doi Suthep road.
- Book Doi Inthanon or elephant sanctuary trips a day ahead on the operator’s site; the popular ones fill up in high season.

Chiang Mai eSIM questions
How much does an eSIM for Chiang Mai 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.
Will the eSIM work on the road to Pai and in the mountains?
In the towns and along the main road, yes. Coverage drops in the valleys between Mae Hong Son and Pai; download the map for the route before you set off and it picks up again in each town.
Can I keep the same plan from Bangkok to Chiang Mai?
Yes. A Thailand plan covers the whole country, so the eSIM you used in Bangkok works on the overnight train, the flight and in Chiang Mai without any change.
