Before using this, I activated roaming on my phone from a network in Thailand, but when I arrived in China, I encountered problems that they couldn't resolve. However, after buying this eSIM, not only did it solve my internet problems, but it also allowed me to use the internet in China very quickly and cheaply. I think it's incredibly worthwhile, much better than roaming, and the internet is super fast.

When I first went to China, I bought a good internet package that lasted me 10 days, but then it started running out 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.

It work really well. I connect directly from the app no need to scan QR. Every time I travel, I’m only gonna buy eSIM on trip.com from now on. On some occasion it can be a little slow. But it’s nothing to make a fuss about.
