The eSIM worked perfectly. Signal was great throughout the whole trip and it was super cheap. We could also access two carriers which was handy. Will be using again!

I was beyond impressed by this eSIM. Purchasing an eSIM is always a gamble, with some so utterly useless that I've opted to travel without one at all. After this experience, I will definitely continue using this eSIM.

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.

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.

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.

I had a very good experience using this eSIM. The setup process was quick and simple, and it worked immediately after activation. The internet speed was reliable for browsing, maps, and social media. It’s very convenient, especially when traveling, because you don’t need to change your physical SIM. I would definitely use it again.
