Made our Japan holiday a breeze!
Wifi Buddy was so helpful! Ordering, collection, and drop off were easy and the wifi buddy team provided everything that was needed to ensure the process ran smoothly. Getting wifi started and using the wifi was so simple, again everything that was needed was provided with simple easy to follow instructions. Coverage and bandwidth were also great. Couldn’t ask for a better service or experience.

Fast and long lasting
A pocket WiFi is probably a necessity when traveling to Japan. We’ve used other pocket WiFi services before but they were never great. But the WiFi buddy was perfect. The internet was fast and it lasts the entire day. They also included an external battery pack, which we never used. We went to Kyoto, Nara, and Osaka and we have no issue with service.

Buddy in the Alps region
Buddy worked, just as I expected from prior experiences with Diamond, No worries about limits etc etc. Only hiccups this time is the Powerbank that comes with it did not work as smoothly. The USB cord connection is loose and did not connect well at times.
