Excellent WiFi
Reception and speed were excellent !! The pocket Japan WiFiBuddy worked better than the Hotel WiFi connections !! Battery lasted about 12 hours each day and the extra external battery was more than sufficient for us to complete our days with great connections !! Price & value were excellent!! Highly recommend

Incredible Service
I have used Japan Wifi Buddy for the past few years, and their service is stellar -- both customer service AND wifi service. Our most recent trip created challenges for us, and the customer service was incredibly helpful land flexible about getting a device to my wife when she arrived. Then, the diamond WifiBuddy was the most reliable device I've used in Japan. The only time we didn't get service was in the mountains of Toyama during a storm -- I don't think ANY service works there though, so I'm not surprised. Every other location we went we had reliable service for my whole family. I will gladly continue to use Japan WifiBuddy on our yearly trips to visit family in Japan.

Recommend WiFi buddy for great service
I visited Japan for two weeks and was very happy with my WiFi buddy service. The device was waiting for me when I arrived at the hotel. Instructions were clear and easy. My family arrive for week two and we had three devices connected most of the time. Return envelope was provided. Everything worked great. I highly recommend.
