Thailand's internet is cheap and reliable. Whether you're a casual user or a heavy internet addict, there's a plan that suits you. Activation takes only 30 seconds while you're waiting at your destination, and once you arrive in Thailand, you can connect directly by activating roaming! Highly recommended!!!

Guest User2026-03-08
450 rubles for 10 days and 30GB, but then I found out there was a special offer and this plan was being increased to a maximum of 15 days and 50GB. I was in Phuket for 7 days and had no problems! Everything is very easy to set up; if your phone supports an e-SIM, the app offers to automatically install it on your device! I was surprised by the quality and price!

Reviews: Thailand AIS 5G eSIM | Unlimited Data | Local Phone Number | ldentity Verification Required | QR code
Guest User2026-03-08
One of the most convenient connectivity options for travelers visiting Thailand, especially for those who want to avoid the hassle of buying a physical SIM card at the airport. The eSIM comes with a QR code for installation, which makes the setup process simple and quick. Once the QR code is scanned, the eSIM profile installs automatically on compatible phones. The process usually takes only a few minutes. However, real-name authentication is required. This means you must submit your passport or identification details before the eSIM can be fully activated. While this extra step may take a little time, it complies with Thai telecommunications regulations and helps ensure legitimate usage.  The AIS 5G eSIM is a reliable and practical option for travelers to Thailand who want fast mobile data and a local number without dealing with physical SIM cards. The real-name verification step adds a bit of friction, but the strong network performance and generous data allowance make it worth

Guest User2026-03-07
It's very easy to activate, takes no more than one minute on an iPhone, and the 1GB plan is always enough for a day of using maps and messaging apps. I've purchased this plan several times, thank you!
