Awesome!
Professional dealing, behavior and advice from beginning to the end. Easy pickup, easy delivery, good coverage, good speed, good battery life Great communication with the team Cannot recommend WiFi Buddy enough. Better internet speed than any mobile dongle in Canada, and plenty for a family of four with two teenagers...;-) You just won a customer and a champion for life (as long as you keep service level as it is) Arigato Gozaimasu!

Fast, reliable service, but battery life could be improved
Easy to use and the Wi-Fi signal was consistently strong (except in certain basement levels of certain buildings, but that’s to be expected). My only recommended area of improvement would be to upgrade devices to ones that have a longer battery life. Our’s would go from full charge to dead in half a day. The provided battery pack came in handy, but if the device could hold a longer charge, the overall experience would have been perfect. Otherwise a great company and service. Will definitely use if we go back to Japan.

Highly Recommend
I have just returned from 4 weeks in Japan. We used the mobile wifi buddy for the entire trip with multiple devices connected and it worked brilliantly. The service, delivery and follow up from Saeko was first class. If we travel to Japan again i will definitely be using this service again. Highly recommend. Thanks
