Which networks does the Thailand eSIM use?

It connects to DTAC and TrueMove H networks in Thailand, with 5G available.

How long does the Thailand eSIM last?

You can choose a plan lasting 7, 15 or 30 days.

How much data do I need for Thailand?

Available allowances range from 0.1GB to 20GB. Choose a smaller allowance for light messaging, maps and browsing, or more data for video, hotspot use and frequent uploads.

Can I top up the Thailand eSIM?

Yes. You can top up the eSIM if you need additional data during your trip.

Does the Thailand eSIM include calls and texts?

No. These plans provide mobile data only; calls and text messages are not included.

Thailand: is an eSIM better than a local SIM?

For most travellers, yes. A local SIM in Thailand means finding a shop once you have landed, usually with ID in hand, and it leaves you on a single carrier. An eSimHero eSIM installs before you travel, works the moment you arrive, and reaches 2 networks — DTAC, TrueMove H — so your phone can move to whichever one has signal. Your usual number stays active on the same phone throughout.

About eSIMs in Thailand

A Thailand eSIM gives you mobile data for your trip without needing a physical SIM. Plans are available for 7, 15 or 30 days, with data allowances ranging from 0.1GB to 20GB.

- DTAC5G
Coverage & networks
In Thailand, the eSIM connects to DTAC and TrueMove H networks, with 5G available. It provides data only, so calls and text messages are not included.
How much data you need
Choose from 0.1GB, 0.5GB, 1GB, 3GB, 5GB, 10GB or 20GB, depending on how much you expect to use. Light use such as messages, maps and occasional browsing may suit a smaller allowance, while video, hotspot use and frequent uploads will use more data. You can top up if you need additional data during your trip.
Setting it up
Select a plan for 7, 15 or 30 days and install the eSIM before using it in Thailand. Check that your device supports eSIM technology and is unlocked before travelling. If your allowance runs low, you can top up rather than buying a new plan.
