Product Info
From February 2025, Overseas Travelers Must Complete Real-Name Registration to Activate AIS eSIM (Detailed instructions for real-name registration)
[Preparation Before Registration]
- Prepare the ICCID on your order voucher (the last 13 digits of the card number) and the phone number.
- Valid identification (Thai ID card or passport from other countries).
- Complete real-name registration before departure (AIS real-name registration website)
- Installing eSIM
- Enable the eSIM upon arrival in Thailand
- It is recommended to complete the real-name registration and eSIM installation within 24 hours before departure.
- The eSIM can be installed ahead of time. Once real-name registration is complete, its validity period is 30 days. You must enter Thailand and finish using the data package within this 30-day window. If you activate it on the 29th day, you will only have 1 day of usage left. Expired packages automatically become invalid and cannot be refunded or exchanged. Please avoid registering too early to prevent premature expiration. Once real-name registration is complete and you arrive in Thailand, the data package will automatically activate as soon as the eSIM connects to the AIS network.
- After successful registration, AIS will send a confirmation SMS. Please keep your AIS eSIM turned on for at least 40 minutes to receive it. (Note: Some devices may not receive this SMS outside of Thailand; you will receive it immediately upon arrival.)
- You can choose to complete real-name registration before installing the eSIM, or install the eSIM before registering. Both sequences work perfectly and will not affect usage.
- One passport can only be used to register a maximum of 3 eSIMs. The passport used will remain tied to the registration until the eSIM's validity period ends. During this period, it cannot be used to register any other AIS SIM cards or eSIMs. Once the validity period ends, the passport will be released for future registrations.

FAQs
1. Which Thailand eSIM options are suitable for high-speed internet access?
For high-speed internet access in Thailand, eSIMs provided by major local telecommunications companies like AIS are excellent options. The AIS Thailand eSIM offers reliable 5G network services with packages like 7 days with 15GB or 10 days with 30GB of high-speed data, followed by unlimited usage at a reduced speed. These plans are designed for travelers needing fast and stable internet across the country.
2. Does the AIS eSIM offer reliable 5G coverage across major tourist destinations in Thailand?
Yes, the AIS eSIM provides extensive 5G network coverage across Thailand's major tourist destinations. As Thailand's number one telecommunications company, AIS ensures robust connectivity from bustling cities like Bangkok to popular holiday spots such as Chiang Mai, Pattaya, and Phuket. Travelers can expect stable and fast internet access throughout their journey.
3. How much data should I consider for a 7 to 10-day trip using an eSIM in Thailand?
For a 7 to 10-day trip to Thailand, an eSIM offering 15GB to 30GB of high-speed data is generally sufficient for most travelers. This amount of data supports activities like navigation, social media browsing, messaging, email, and occasional video streaming. After the high-speed allowance is used, many plans, including the AIS eSIM, offer unlimited data at a slower speed, ensuring continuous connectivity for basic needs.
4. Can tourists acquire an AIS eSIM for use during their visit to Thailand?
Yes, international tourists can acquire an AIS eSIM for their trip to Thailand. It can be conveniently ordered online and activated quickly, often within hours of purchase. However, it's important to note that from February 2025 onwards, overseas travelers will be required to complete a real-name registration process to activate their AIS eSIM, aligning with local regulations.
5. What is the process for purchasing and activating an AIS eSIM online for Thailand travel?
You can conveniently purchase an AIS eSIM online through KKday. The process involves placing an order, receiving a digital voucher, and then installing the eSIM directly onto your device. There's no need for physical collection or redemption. For iOS users, if you update to the latest KKday App version and iOS 17.4 or above, you can enjoy one-click installation directly from the app, making activation swift and hassle-free.
6. What are the key differences between using an AIS eSIM versus a traditional physical SIM card in Thailand?
The key differences between an AIS eSIM and a physical SIM card for Thailand travel lie in convenience and flexibility. An eSIM offers digital activation, eliminating the need to physically swap cards or visit a store for collection. It also allows you to store multiple mobile plans on a single device, easily switching between them. A physical SIM requires a dedicated slot and physical handling, which can be less convenient for travelers.
7. Does the Thailand eSIM support hotspot sharing for other devices?
Yes, the Thailand eSIM does support hotspot sharing. This feature allows you to connect other devices, such as laptops or tablets, to your phone's internet connection. It's a convenient way to ensure all your travel companions or devices stay connected using a single eSIM data plan.
8. Are there any specific requirements for AIS eSIM activation for international travelers from February 2025 onwards?
Yes, from February 2025, international travelers activating an AIS eSIM in Thailand will be required to complete a real-name registration process. This is a mandatory step for activation, implemented to comply with local telecommunication regulations. Travelers should be prepared to provide necessary identification for this registration to ensure their eSIM can be successfully activated and used.
