Before you go
Plans here run on TrueMove H (5G), DTAC (5G), AIS (5G) and True Move (4G); each plan names its operator and its best generation. 5G is included where the operator has it and your phone supports the local bands; elsewhere you get 4G.
Maps, messaging, ride apps and a few photos use about 300 to 500 MB a day, so 1 GB covers a short stay and 3 to 5 GB a week of normal use. The smallest plan is 500 MB · 7 days for $1.10; a longer trip is cheaper per gigabyte on a bigger plan. For video calls, streaming or a hotspot for a laptop, unlimited daily data starts at $1.38 a day. Most plans top up from your order page if you run low.
Most of our customers land in Bangkok and Phuket and travel on to Chiang Mai, Pattaya and Krabi. Coverage follows the operator’s network, so a city centre, an airport and a main road are covered everywhere; remote coast and mountains depend on the plan’s operator.
Tourist SIM cards are sold at Suvarnabhumi and Don Mueang arrivals and in every 7-Eleven, but each one is registered to your passport at the counter and you queue after a long flight. An eSIM skips the counter and works as the plane doors open.

These multi-country eSIMs include Thailand and keep working when you cross a border.
Why an eSIM
Landing in Thailand with data already working means maps, translation and your ride from the airport are ready before you reach the exit. No kiosk, no passport photocopy, no hunting for Wi-Fi.
Your home SIM stays in the phone for calls and texts. The eSIM handles data on local networks, so you avoid roaming bills without losing your number.
Install on Wi-Fi at home and keep the line switched off until you land. Validity starts the first time it connects abroad, not when you buy.
How our Thailand prices compare with Airalo, Holafly, Saily and Nomad →Good to know
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.
On nearly every plan, the first time the eSIM connects to a network abroad, not when you buy or install it. A few plans start on installation; each plan says which. Install within 180 days of purchase.
Turn the travel line on, enable data roaming for that line only, and set it as your mobile data line. Keep data roaming off on your home line. Most phones set the APN automatically. If you are connected but have no data, enter the APN shown on your order page or eSIM page (none shown means the phone sets it itself), or reply to your order email and we will help.
Each Thailand plan lists its operators and whether they run 3G, 4G or 5G; each plan card shows its best generation. Daily unlimited plans slow to the fair-use speed shown on the plan once the day's full-speed data is used.
Most plans can be topped up from your order page, with more data for the same area or more days. Plans marked non-reloadable cannot; buy a new one and it installs the same way.
Yes, personal hotspot works on every plan.
AIS has the widest coverage on Koh Samui, Koh Phangan, Koh Tao and the Andaman islands, with TrueMove H close behind. Both are 5G in Bangkok, Phuket and Chiang Mai. On a boat between islands expect 4G or less.
No. Registration applies to physical SIM cards bought in Thailand. A travel eSIM is issued abroad and needs no local paperwork, which is why it works the moment you land.
