Great service.
Very friendly email contact, and very efficient service. The device was waiting for us at our hotel. It was easy to set up and worked perfectly. Thank you!

Made my trip better
I recently completed a train tour of Honshu and Kyushu. Having regular access to WiFi was a big help as the free public services can be slow and unreliable. In only a few instances was I unable to connect at a decent speed. Recommended if you need to stay connected.

Good wi-fi for my 21 days
I think it's great that you offer an extra battery for the pocket wifi because I definitely drained it quite a bit when I was there. Although I did have some difficulty charging it during my last week. When I plugged it in overnight, it didn't charge at all... but otherwise great service! I had no problems with the pocket wifi and the speed was pretty good throughout my trip ^^ So thank you! (I probably should have contacted you about my extra battery but I had an Airbnb host who had an extra pocket wifi so I ended up using both.)
