We decided against mobile SIM card or e-sim, because this would've drained the battery too much when using it as hotspot the entire day. This solution was just perfect for us and we would do it again next time for sure.

The pickup and drop were seamless and the network coverage was efficient throughout the places I visited in Japan.

The modem was really good, and we were able to use till the end of the day, just a couple of time we ended to use the power bank. The speed of the WiFi was quite good (I didn't do any speed test).
I didn't give 5 stars, because we had some issue in the beginning (no internet connection, probably due to the provider and not related to the WiFi modem), and we lost some time in the airport.

Wifi worked well and was easy to use. We had great connection wherever we visited and appreciated that very much. Thank you for your great customer
relations!

Servizio eccellente, ritirati in albergo, facile da usare sempre connesso.

Very fast connection. The company very good customer service. Will definitely recommend

Used for 9 days in Tokyo, worked flawlessly.

Coverage was good. Staffs are responsible, friendly and fast to respond.

Very small device that worked as advertised. Strong connection and good service. The battery lasts less than a cell phone so if you are out all day, just be prepared for the battery to run out.

Worked perfectly. No connection problems wherever we went.
