A good option for the money, the internet doesn't use up quickly (as it happens with other operators and countries).

★

Guest User2026-01-21

It's convenient that you can extend the SIM card's validity without reinstalling it. The signal, of course, can be a bit weak. But as I noticed in Vietnam, even Wi-Fi can't always download data quickly.

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.

I bought two eSIM cards for Android and iOS. I installed them in less than a minute by scanning the QR code from the confirmation email. I used Wi-Fi to activate the SIM card.

That was really easy to install and use it. I was even able to use it on the island. Highly recommend 🔥

I ordered two eSIM cards. One for me and one for my wife. For some reason, the connection didn't work in China, which was disappointing at first. Then it turned out I needed to enable roaming in the SIM card settings (iPhone 17). And I got a connection in the Philippines. The reception is pretty good, you can even make video calls.
