Really great service, coverage, and speeds!
Was really pleased with the service and especially the download speeds. Needed wifi to be able to watch streaming video as required by my job out here in Japan, and the videos played in great quality without issue!

Best pocket wifi!
Got the Diamond plan. Pocket wifi stayed on for the whole day before we needed to use the portable charger. Good connection especially when we went to crowded places such as Tokyo Disney and DisneySea. Will definitely use this again!

Recent Trip to Japan
The Diamond WiFi Buddy worked great for daily use as a traveler in need of uninterrupted internet access. Whether it was for Train, Subway, Bus, or simply just searching Google I had a great experience with no issues. The only drawback was the battery life but nevertheless the backup battery charger provided came in handy. Japan Wifi Buddy, you guys are doing it right! Arigatōgozaimashita. -Anthony
