Does dtac offer an eSIM for tourists?
Yes, dtac offers two tourist eSIM plans that provide visitors with mobile data, calls, and texts within Thailand. Unlike dtac’s regular prepaid and postpaid plans, which are meant for Thai locals, these plans are there to provide a reliable connection for tourists.
dtac eSIM plans and pricing for Thailand
The two dtac Thailand eSIM plans for tourists are nearly identical apart from their validity period and the high-speed data allowance included in the plan. Both offer unlimited data, 15 baht credit for calls to other networks, and unlimited calls to phone numbers within the dtac network.
| Validity | High-speed data | Price |
|---|---|---|
| 8 days | 15 GB | 299 baht (~US$9.30) |
| 15 days | 30 GB | 599 baht (~$18.60) |
Once you use up your high-speed data allowance, the connection is slowed down, but you’ll still have mobile internet in Thailand.
dtac mobile network coverage and speed
dtac has excellent coverage throughout Thailand, with 5G coverage available in most of the country. This means you should be able to use high-speed data and make and receive calls without interruptions as long as you’re not somewhere out in the mountains or the jungle, where connectivity can be poor or non-existent.
As far as speeds are concerned, dtac was the third-fastest mobile network in Thailand according to the 2025 Speedtest awards, just behind AIS eSIMs and True eSIMs.
Where to get a dtac eSIM in Thailand
Getting a dtac eSIM in Thailand is easy, since they’re available at the main international airports, dedicated stores, and online. Here’s how you can get yours:
- At the airport: You’ll find dtac counters upon arrival at Suvarnabhumi and Don Mueang airports, where you can buy a dtac eSIM or physical SIM card as soon as you land.
- Official stores: Left the airport without getting your eSIM or SIM for Thailand? You can do so at any official dtac store in the country, which are easy to find at any of the bigger cities.
- Online: Unlike traditional SIM cards, eSIMs are completely digital, so you can simply buy your dtac eSIM online through the dtac website and get connected without ever visiting a physical store.
