English
An eSIM for Thailand is a digital data plan for the phone you already own. There is no physical SIM card, no airport lines, and no passport needed. Your plan is ready on your SIMAREA account before you even leave home.
It works safely alongside your normal SIM. You keep your own number for calls and important text messages. Your data goes through the SIMAREA plan. Just turn off data roaming on your home SIM to avoid high bills.
Coverage comes from DTAC, TrueMove H and True Move, depending on the plan. Your phone connects when you arrive and, on a plan with more than one network, moves to the stronger signal.
If you stay longer, some plans can be topped up with more data; a fixed one needs a new plan.
What it is not: a local phone number. If you need a number for verification codes, see virtual numbers.
Thailand eSIM: data on DTAC and TrueMove H
5GMobile data for Thailand on the phone you travel with. Nearly every plan joins DTAC or TrueMove H and waits for your first connection in Thailand before counting days, so you can set it up at home.
The unlimited plan is the day pass we feature for Thailand: after its daily full-speed allowance it keeps you connected at a lower speed, and it is billed per day for the days you choose. Fixed plans are one price for the term shown. Nothing on this page is an estimate.
How to get mobile data in Thailand
Install it at home before you go. Some plans here start counting at installation, so check the line under the price for the plan you pick.
Pick eSIM plan
Choose how long you are there. The day pass is billed per day, so the term is yours to set.
Pay, then scan
Charged from your balance, which you top up with crypto. Your QR code is in your dashboard once the order is paid.
Turn it on when you arrive
Turn on data roaming for your SIMAREA plan when you arrive, and it joins a partner network.
What to know about an eSIM for Thailand
The specifics that decide whether a travel eSIM is useful once you're actually there.
More than one network on some plans
Plans here use DTAC, TrueMove H and True Move. Some plans have more than one, and your phone switches to the stronger signal; the technical specs show the networks of the plan you select.
Set up before you go
No SIM card store, no passport check. Install it at home, then turn on data roaming for it when you arrive.
Hotspot sharing
Share your internet with a laptop or a friend, if your plan and phone allow it.
Keep your own number
The eSIM is just for internet. Your normal SIM still receives calls and important bank codes. You can use both at once.
Staying longer?
Some plans here can be topped up with more data on the same eSIM; others are fixed.
If it does not work
Not installed or connected yet? Ask for a refund within 30 days of buying it. Installed but not working on any of its networks? Support helps, and refunds you if it cannot be fixed.
eSIM Thailand: DTAC and TrueMove H, or a Thai IP
The Thailand plans on this page come in two kinds. What separates them is the network and the place your traffic leaves for the internet.
- DTAC and TrueMove H, with a Hong Kong exit. Every plan but one lists both networks. Each is listed with 5G, and the plans allow 5G too, so you're on 5G where the network has it and on 4G/LTE elsewhere. Your phone registers on whichever of the two it finds stronger. Traffic leaves through Hong Kong, so websites see a Hong Kong IP address.
- True Move, with a Thai exit. The 50 GB plan for 10 days is the only one with a Thai IP address. It lists a single network, True Move, on 4G/LTE. It can't be topped up, and its days start when you install it.
For maps, Grab, LINE and messaging, the Hong Kong exit changes nothing. A Thai banking app, a Thai streaming service, or a site that sets prices by country may treat a Hong Kong address as abroad. If a Thai IP is the reason you're buying, take the 10-day plan, or ask support before you pay; it answers 24/7.
AIS isn't on any plan this page sells. It shows up on some Asia plans and on the global plan, described in the last section.
Thai eSIM plans: fixed data and the day pass
A fixed plan is one amount of data for a set number of days. These are the Thailand sizes on sale on November 2, 2026:
- 7 days: 100 MB, 500 MB or 1 GB
- 10 days: 50 GB, the Thai-IP plan on True Move
- 15 days: 2 GB or 3 GB
- 30 days: 3, 5, 10, 20 or 50 GB
- 180 days: 50 GB
The day pass works by the day instead. You get 1 GB at full speed every day on DTAC or TrueMove H; once that's used, the connection carries on at 1 Mbps until the day resets. You choose how many days in the picker. Sellers often call this kind of plan unlimited, and it's true that the data doesn't stop, but only the first gigabyte of each day runs at full speed. At 1 Mbps, messages, maps and music keep working; video drops to low quality.
Bangkok, then the islands
A few days in the city and a ferry south is mostly maps, ride-hailing, ferry tickets and photos sent home. The 3 GB plan for 15 days covers a light version of that. If you'd rather not watch a counter while hopping between Krabi and Koh Lanta, the day pass gives you a fresh full-speed gigabyte each day.
A month of remote work in Chiang Mai
Video calls and a laptop on hotspot, if your plan and phone allow it, use far more data than sightseeing. The 30-day plans with 20 GB and 50 GB carry the most for a month. The Thai-IP plan holds 50 GB too, but it ends after 10 days and can't be extended.
A whole season
The 50 GB plan for 180 days is the one sized for months rather than weeks, for a winter on the Andaman coast or a long study stay. If its data runs out before its days do, add more on the same eSIM.
Thailand travel eSIM: install at home, count from arrival
Install the eSIM over Wi-Fi before you leave, days ahead if you like. Most Thailand plans don't count a single day until your phone first connects to DTAC or TrueMove H after you land in Bangkok, Phuket or Chiang Mai. Two plans start at installation instead: the 100 MB plan for 7 days and the 10-day Thai-IP plan. Leave those until the day you fly, or install them once you've landed and found Wi-Fi.
Short of data halfway through? Every plan on DTAC and TrueMove H, the day pass included, takes a top-up on the same eSIM, with no new QR code. The 10-day Thai-IP plan doesn't: when its data or days run out, you buy a new plan. On the page, the line under the price says when the selected plan's days start, and the Add more row under Plan details says whether it can be topped up.
Thailand with Laos, Cambodia, Malaysia or Vietnam
A Thailand plan works in Thailand and stops at the border. For a trip that crosses into a neighbor, every plan on the Asia eSIM page includes Thailand, but the country lists differ, and so do the Thai networks:
- With Cambodia, Malaysia or Vietnam: the Southeast Asia plans list seven countries: Thailand, Cambodia, Malaysia, Vietnam, Singapore, Indonesia and the Philippines. In Thailand they use DTAC and TrueMove H, like the Thailand plans, and they exit in Hong Kong. Two wider Asia lists, of 12 and 20 locations, add Japan, South Korea and mainland China and work the same way in Thailand.
- With Laos: only the Asia plans for 19 locations include Laos, and those leave out Cambodia. In Thailand they list AIS, TrueMove H and CAT, and their traffic exits in the UK or Norway. The Asia day pass is one of them, with 1 GB a day and then 384 Kbps, a slower fallback than the 1 Mbps of the Thailand pass.
No plan on the Asia page covers Thailand, Laos and Cambodia together. For that loop, keep a Thailand plan for the Thai part and add a Laos eSIM or a Cambodia eSIM for the days across the border. The Coverage row under Plan details lists every country of the plan you select, so check it before you pay.
Going further than Asia? The Global 130 eSIM covers Thailand on AIS, TrueMove H and CAT, together with Malaysia, Cambodia, Vietnam and most of Europe, with fixed plans from 7 to 365 days.
Thailand eSIM questions
Does a Thailand eSIM come with a Thai phone number?
No. The eSIM carries data only, so there's no +66 number on it, and your usual SIM keeps your own number for calls and texts. SIMAREA doesn't rent Thai numbers today; the virtual numbers page lists the countries it does.
Will it work on Koh Samui, Koh Phangan and Koh Tao?
Yes. A Thailand plan covers the whole country, the islands included, and there are no separate plans for the north or the south. You have data wherever DTAC or TrueMove H has a signal, or True Move on the 10-day plan.
Can I use Grab, Bolt and LINE on it?
Yes. They run on mobile data like any other app. LINE and WhatsApp calls also travel over data, so they count against your plan, or against the day pass's daily 1 GB at full speed. Codes that apps send by SMS go to your home number on your regular SIM, so you get them as long as your home line receives texts abroad.
Which plan suits a stay of three months or more?
The 50 GB plan for 180 days, the longest Thailand plan, and it can be topped up on the same eSIM. If the stay includes trips to neighboring countries, the Asia page has 20 GB for 90 days and 50 GB for 180 days on lists that include Thailand. The Global 130 eSIM runs as long as 365 days, but with only 1 GB for that whole term.
Can I get a Thai IP address?
Yes, on one plan: 50 GB for 10 days on True Move, which exits in Thailand. Every other plan on this page exits in Hong Kong. The Thai-IP plan starts counting at installation and can't be topped up, so install it on arrival day and plan a new purchase when it ends.
I forgot to install the eSIM before the flight. Can I do it at Suvarnabhumi?
Yes, as long as you can get online first: installing needs a connection, so join the terminal's Wi-Fi, open your SIMAREA account and scan the QR code from there. Plans that count from the first connection lose nothing by waiting. The two that count from installation start the moment you add them, which on arrival day is what you want anyway.
