Does AIS offer an eSIM for tourists?
Yes, AIS offers four different eSIM plans for tourists, each differing only in validity period. The validity ranges from 5 to 30 days, with each plan offering unlimited data and unlimited calls within the AIS network. You also get a 100 baht credit for calls to other networks in Thailand and international calls.
AIS eSIM for Thailand: Plans and pricing
The pricing for AIS cellular plans for tourists is pretty straightforward. Since all plans offer the same benefits, you simply need to choose a validity period that matches the duration of your stay in Thailand.
| Validity | Price, US$ |
|---|---|
| 5 days | $12.14 |
| 8 days | $15.18 |
| 15 days | $21.26 |
| 30 days | $36.47 |
The value for money gets better as the validity period increases, so it’s almost always better to buy a plan that exceeds your stay instead of trying to exactly match your trip with multiple plans.
All AIS Thailand eSIM plans for tourists include unlimited mobile internet in Thailand, so you won’t have to worry about running out of bandwidth, buying more data, or tracking your data usage.
AIS network coverage and speed
Being one of the top network providers in Thailand, AIS offers solid coverage in the country. You can expect 4G or 5G coverage almost anywhere you go, unless you wander far off into the wilderness and away from the cities.
On top of that, AIS was named the fastest network in Thailand in the 2025 Speedtest awards. So not only do you get reliable internet access, you’ll be able to enjoy high-speed 5G data in Thailand’s major hubs.
Where to get an AIS eSIM in Thailand
You can buy an AIS eSIM in any AIS shop nationwide or online, which means you won’t have any issues getting one yourself. Here are some of the main options:
- At the airport: You can buy your AIS eSIM or physical SIM for Thailand at any international airport within the country, including the Don Mueang and Suvarnabhumi airports.
- Official stores: Left the airport without your eSIM? You can get one at any official AIS store in Thailand.
- Online: Since eSIMs are completely digital, you can buy your plan at the AIS online store and activate it by following the instructions in the email you’ll receive after purchase.
How to get an AIS Thailand eSIM for travelers
All you need to get an AIS eSIM is your passport and an eSIM-compatible device. When shopping online, you may be asked to upload your passport pictures before you can buy your plan. In physical stores, simply have the passport with you and provide it to the shop employee when asked to.
How to activate eSIM with AIS
The AIS eSIM activation process doesn’t take long. Upon purchase, you’ll receive a QR code in your email. Simply scan the code and follow the prompts to set up your eSIM.

Which eSIM-compatible devices work with the AIS Thailand eSIM?
AIS eSIMs work with most eSIM-compatible phones, including iPhones XR and later and Samsung S20 and later models. The eSIMs can also be installed on eSIM-compatible watches and tablets.
Make sure to check if your phone is unlocked before your trip to Thailand. You won’t be able to use your phone in Thailand if it’s carrier-locked, even if it’s eSIM-compatible.
