Every eSIM on this page roams onto Thailand's national mobile networks. Coverage is strongest in cities and along major routes; check the provider's coverage map for remote areas.
Install before you fly over Wi-Fi โ your data allowance only starts when you arrive and connect to a local network.
For a typical week of maps, messaging, social media and the occasional video, 5โ10 GB is plenty. Light users checking email and directions can get by on 1โ3 GB, while remote workers, heavy streamers or anyone tethering a laptop should look at 20 GB or an unlimited plan. Because plans are cheap, it is usually worth sizing up a tier rather than risk running out mid-trip.
If Thailand is your only stop, a single-country plan gives the best price per GB. Visiting neighbouring countries on the same trip? A regional plan covers many countries on one eSIM โ slightly pricier per GB, but you skip buying a second SIM at the border.
Carrier roaming is the most expensive option and often metered by the day. A physical tourist SIM means queueing at the airport and swapping out your home number. An eSIM keeps your regular number active for calls and texts while a second data line handles the internet โ installed in minutes, before you even leave home.
