Great customer service, even better product!
I used the Diamond WifiBuddy for 12 days in Japan and was very satisfied quth the service. The device always delivered LTE speed service all over Japan, and the team was always ready to help with any questions that came up. Pick up at a post office also worked very smoothly. I will be using it again when I come back to Japan!

Was a perfect addition to our trip!
We loved the WifiBuddy! It kept us online our entire trip, even in the subways! We travelled in Hiroshima, Osaka, Kyoto, and Tokyo, and had perfect reception everywhere! The battery life was pretty good, but the additional battery that was provided was a great way to keep it lasting the full day!

A great companion for the trip
I traveled with two other friends and we found the WifiBuddy to be incredibly convenient. The WifiBuddy allowed my friends and I to look up directions anywhere we were, including inside the subway since there are repeaters installed there. The WifiBuddy also worked on the Shinkansen (bullet train) which was a nice surprise and it allowed us to goof around on our phones while commuting to different cities. I would definitely use this again when I go back to Japan!
