Great service!
Super easy to use and was ready at my hotel when I arrived in Japan. Speeds and wifi coverage were extremely reliable. Portable battery was really helpful as well!

Wasn’t the fastest wifi provider I’ve used in Japan
The wifi buddy was good but it wasn’t the fastest wifi provider I’ve used in my travels to Japan

5 stars!!!
I was impressed with the service and communication of JWB. The device was perfect for our days out in Japan. The device got a little hot in my bag on on the hot days so had to carry it sometimes. Other than that, no issues.

Rented the diamond
It was good for the most part, it had some random restart or speed drop, but most of the time it work perfectly.
