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.

It's very easy to use, no need to change SIM cards, which is hassle-free. The price is better than roaming too. We bought a 5G per day plan and we still had more than enough. We didn't run out in a full day. Typically, we use it for Line, sending photos, using Google Maps, and posting Instagram stories occasionally. We don't watch TikTok or YouTube. Even in rural areas, there's internet access.

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.

Guest User2026-01-11
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.

Easy to install, no need to pay for any extra roaming cost. The signal is better when you are in the city
