Initial activation was easy to use and worked well. Connection was great throughout our trip! However the request renewal function did not work and my data stopped working despite adding on additional data.

Straightforward- just install before departure and activate when landed. No hassle, no complicated processes, no issues-no dead spots, stable connections.

Excellent connection, internet tethering is possible. Everything opened smoothly. With other eSIMs, some apps take a long time to load, but this one didn't have that issue.

I used this in KL, Bangkok and Shanghai. Overall the signal was ok. Sometimes we do get a drop out but it’s not often. We managed to use all social media platforms with this eSIM at Shanghai. Only thing is if you want to hail a ride you’ll need a number for it in china.

It's very convenient to use, communication is smooth, connections are always stable, and you can even share the network. It offers generous data allowances at an affordable price—highly recommended.
