Guest User2025-09-08

The QR code was sent quickly, and when I opened it, it showed a message from Softbank. The Softbank native card should be working. I used to use the physical white card, and this is my first time using esim. I hope it works well.

Mount Aso is an absolute must-visit in Japan. Unbeatable value for the ticket price!

Guest User2025-09-24

Coming to Japan alone is comfortable. No need to worry about communication. The signal is good, no cuts. Plus, you can watch many series. Calling the hotel, the signal is good. It's very good. Normally, I use roaming, so the internet runs out very quickly.

I traveled through 5 countries in Asia over the course of 3 months, and the network has been very stable the whole time. It has never dropped the connection. So I definitely have to come and leave a good review. This eSIM is absolutely worth buying.
