Reviews: Thailand AIS Native 5G eSIM | Supports TikTok & ChatGPT | Includes Local Calls & SMS | Total Package | 7–10 Days | Real-Name Registration Required | Calendar Day Billing | QR code
Guest User2026-04-14
I got one for myself and my wife before flying to Thailand. I had a minor issue with logging in. I couldn't get through on my phone; I got an error like "outdated browser version," which is weird. I updated it a couple of months ago. I logged in on my MacBook. My wife got it on her phone. As soon as we landed in Thailand, we had internet right away, right up until the last day. Even though we had unlimited data, I only used 20 GB in 10 days. I didn't even use the hotel WiFi; it was a bit slow. 5G was everywhere. The speed was impressive.

You will never run out of data with this. When you go to a mall or area with wifi, your phone will automatically use truemove wifi. And the speed is very fast too. Would definitely use it again.

Great SIM card, inexpensive, and a good 20-day plan. I bought two eSIMs at once, one for me and my husband. I accidentally activated both on my phone incorrectly—I was in a hurry—but tech support helped me quickly, sent me a different QR code, and everything works great. Thanks!

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.
