Both the connection and the call quality are excellent. The tariff renewal was smooth and unnoticeable. We are very satisfied.

I buy all my eSIMs here before traveling abroad. Installation is very convenient, and you don't have to worry about installing the wrong one because you can reinstall them. The network speed is also quite fast. I install it on the day I arrive, and I can connect to the internet directly as soon as I start my flight. Except for a few countries where the local network is poor and affects the speed, the speed is generally quite fast.

Upon arrival at Bangkok airport, we connected to Wi-Fi, clicked INSTALL in the trip.com app, and voila. Everything worked.

It worked perfectly without any complaints and I used it without any issues. Could there be a better review than this??? Haha. The hotspot worked well too. It connected well from the airport to Ao Nang Beach and 4landsd, so I used it without any problems!! Just so you know!!
