The most challenging part was finding the booth at Haneda Airport. After that, everything was fine. The unit worked well, we charged it every night. Didn’t need the provided back up battery. Return in the Japan Post box was easy.

This is the first time we tried Japan wireless and compared to another service we used for years, the connection was excellent and so much better. Japan wireless will be our go to service from now on!

Strong 4G connection everywhere I went with superb WiFi signal for 5 devices.

My eSIM worked flawlessly in Osaka, Kobe and in the Main Okinawa island. Fast enough to stream some videos and sustain FaceTime calls. Excellent back up to my regular carrier data plan (T-Mobile). Not the cheapest option dough but reliable.

Highly recommend, easy pickup from Narita airport, device held its charge throughout the entire day. Wifi was sometimes spotty throughout some areas however I think this was due to cellular coverage as a whole and not the device. Drop off was a breeze via the Japan mail postbox at Osaka airport before flying home.

We were really happy with the service, from ease of picking up the device at the airport to the reliable connect and the convenience of returning the devise. We will definitely Lise your company next time.

I had a great experience using J-Wireless mobile data. I stayed in Osaka for 11 days and made day trips to Kyoto, Kobe, and Nara. Reception was pretty much always available. Only time I had no signal was around super busy areas in the heart of Osaka. I used my Samsung Galaxy s23 ultra and my husband used his iPhone 12 pro. Excellent service overall. Will use again when I visit Japan next time!

Great product, easy to use, never had an issue. Will definitely use again!

Excellent service !

The portable hotspot was waiting for us at the hotel when we checked in, worked perfectly for the whole day without running out of charge, and was easily dropped back into a mailbox on our way through the airport when leaving. The most effortless part of our entire trip.
