Japan WifiBuddy: An absolute must!
We recently returned from a 2-week holiday in Japan, and our Japan Wifi Buddy was a key element of the success of our holiday. It was delivered (as requested) to our first hotel, and we carried it with us all the time, and returned it at the end in the reply-paid envelope supplied. Great customer service and great wifi reception regardless of our location meant that we were connect to the Internet at all times, which was exactly what we were after. Many thanks! We recommend your service unreservedly and will use you again when we return to Japan.

The best money we spent while in Japan
So handy! The pocket wifi lasted for 10+ hours and was super easy to just pop into our bag and use all day. It was amazing to not have to worry about going over data limits. I would definitely recommend!

2x Diamond WifiBuddy
While the wifibuddy was good to bring around, the portable batteries that the pack came with seemed to not work forcing us to use our own portable batteries.

A great travel companion!
Being able to access maps and reviews and helpful tips online while traveling in Japan was the absolute best. I would not visit Japan again without this service!

Easy and worked well
Had a great experience with Japan WiFi Buddy. The ordering was simple, pickup at the post office in the airport went smoothly, and the data service was rock solid and worked everywhere we went.
