Reviews: Japan 4G/5G eSIM 1-30 days High-speed data Daily package/Data package Optional days (calendar day) QR code

I used this sim in Okinawa, don't know if it's the same across all Japan but in some areas, i will lose the connection. Maybe Okinawa is just rural, but just a few minutes so it's still fine.★

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.★

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.
