Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

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.

The network card provided by this adapter in Osaka demonstrated a very stable and fast signal, and was easy to install. It is also very reasonably priced.

The network is still working great after I recharged it. I haven't run into any issues at all. I've tested it, and this esim can be used long-term. It's totally fine!
