Networks in Thailand
Thailand's market consolidated to two large operators, AIS and True, after the True–dtac merger. Both run 4G LTE nationwide with 5G in Bangkok, Phuket, Chiang Mai and other tourist centres, and legacy 2G/3G services are being retired. Local prepaid SIMs require passport registration at the point of sale; a roaming eSIM does not.
Activation on arrival
Install over Wi-Fi before you fly; Suvarnabhumi, Don Mueang, Phuket and Chiang Mai airports all have free Wi-Fi if you install on arrival. There is no need to queue at an airport SIM counter or hand over your passport. The profile activates automatically when the phone registers on a Thai network.
Where coverage is strong
Coverage is strong in Bangkok, Chiang Mai, Phuket, Krabi, Pattaya, Koh Samui and along the main highways. Boat crossings between islands, jungle areas in the north and parts of the smaller islands can drop to slower speeds or no signal — that applies to every eSIM and to Thai prepaid SIMs equally.
Frequently asked questions
Does FastAlo offer an unlimited Thailand eSIM?
Yes. FastAlo unlimited Thailand bundles include a full-speed allowance each day — from 500 MB up to 10 GB depending on the plan — then continue at reduced speed until the allowance resets. The 7-day 1 GB/day bundle is $7.99.
Do I need to register my passport for a Thai eSIM?
No. Passport registration applies to local prepaid SIM cards bought in Thailand. A FastAlo travel eSIM roams on Thai partner networks and needs no registration or store visit.
Which Thai network does a FastAlo eSIM use?
FastAlo Thailand eSIMs roam on Thai partner networks — AIS or True depending on the plan. Both are national 4G LTE networks with 5G in the main cities and resort areas.
Will the eSIM work on the islands?
Yes on the populated islands such as Phuket, Koh Samui, Koh Phangan and Koh Chang. Expect gaps on boat crossings and on remote beaches, as with any Thai SIM.
How much data do I need for two weeks in Thailand?
Maps, Grab, messaging and photo uploads typically use around 0.5–1 GB a day, so 10 GB covers a two-week trip for most travellers.
