Thailand travel data guide
A Thailand eSIM from RoamZivo is a prepaid data plan for Thailand that you install before you fly. Plans in Thailand run on TrueMove H, DTAC, AIS and True Move, with 5G where the operator offers it. The eSIM is data only, so your own SIM stays in for calls and texts.
There are 21 plans to choose from. Data sizes run from 1 GB to 50 GB, validity from 1 to 30 days, and prices start at $1.99. Unlimited plans are listed too, each with its own fair use line. Hotspot sharing is supported on every plan. Top ups are available on some of the fixed data plans and go onto the same eSIM.
Visiting more than one country? The Southeast Asia eSIM covers Thailand and 7 other countries on one plan, from $2.99. The Asia (14 countries) eSIM covers Thailand and 13 other countries on one plan, from $2.99. The Asia Pacific eSIM covers Thailand and 19 other countries on one plan, from $10.99. The Global eSIM covers Thailand and 126 other countries on one plan, from $18.99.
Your days start the first time the eSIM connects in Thailand, not when you buy, so you can install it at home days early. For a week of maps, messaging and social apps, most travellers are fine with 3 to 5 GB. Video calls or streaming need more, or an unlimited plan. Travel data in Thailand from RoamZivo arrives as a QR code by email, with a copy kept in your account.
Thailand FAQ
Does the eSIM work everywhere in Thailand?
It connects wherever TrueMove H, DTAC, AIS and True Move have signal, which is the same network local customers use. The eSIM is data only.
When do my days start?
On the first connection in Thailand, not at purchase. The plan selected above (2 GB) runs for 15 days from that moment. You can install the eSIM at home and the clock stays still until you connect.
Do I get a local phone number in Thailand?
No. The eSIM is data only. Your own SIM stays in for calls and texts, and WhatsApp keeps working over the eSIM data.
Can I share data with my laptop?
Yes. Hotspot sharing is supported on the plan selected above, so your laptop or tablet can use the eSIM data through your phone.
Is 50 GB for 10 days a good choice for Thailand?
Yes, if you use a lot of data on a trip of about ten days in Thailand. 50 GB over 10 days averages 5 GB a day, and as a fixed plan it has no daily slowdown. Check the plan details for hotspot if you want to share it.
Do I get a Thai phone number?
No, the Thailand eSIM is data only and does not include a Thai number. Calls and SMS stay on your own SIM. If a local service needs to send a text to a Thai number, this eSIM cannot receive it.
Should I buy a Thailand plan or the Southeast Asia plan?
Buy a Thailand plan if you are staying in Thailand, because it gives you 22 plans to choose from. The Southeast Asia plan is for trips that continue to places such as Vietnam or Cambodia. It covers 8 countries on one eSIM.
When do the days start on my Thailand eSIM?
The days on a Thailand eSIM start at its first connection to a Thai network. They do not start when you pay or when you scan the QR code. An 8 day plan first used on arrival still has its full 8 days.
Can I install the eSIM after I arrive in Thailand?
Yes, you can install it after you arrive in Thailand, as long as you have WiFi to download it. Doing it at home is less stressful, since you are not hunting for a connection at the airport. Either way the plan starts at the first connection.
Do all Thailand plans allow hotspot?
No, hotspot is allowed on some Thailand plans and not on others. Look at the plan details before you buy. If sharing is important and your trip covers several countries, the Southeast Asia plan allows hotspot on all of its plans.
Why is my unlimited data slow in Thailand?
The usual reason is that you have passed the daily full speed amount on your Thailand plan. That amount is 1 GB or 3 GB, depending on the plan, and after it the speed is up to 1 Mbps. Full speed returns the next day without you doing anything.
How do I top up if I run low?
The plan selected above does not offer top ups. Buy a new plan from this page instead and install it as a second eSIM.
