Easy, affordable and reliable
This was such an easy wayt to have internet access throughout our trip. It worked everywhere we were. The only challenge was keeping it charged and the extra charger included helped with that.

Platinum wifi
We used the Platinum WiFi Buddy system during our travels in Japan from Tokyo to Kyoto to Hiroshima. The system worked well throughout the journey even on the Shinkasen. But we learned it has a few limitations..first make sure only one person is using it at time as the battery is the limiting factor on how long the system will work. My wife was the primary user but if I wanted to get internet access I would let her know and immediately turn off my wifi access when I was done. I was told that you had to completely shut down the Wifi buddy when recharging at night, but we had access to the hotel internet so that wasn't a big deal. The company sends a spare battery for day use...so when we could not access the internet we checked the battery level which was usually low and we hooked up the spare battery to the system...The WiFi buddy was indispensable during our travels and I highly recommend it to anyone traveling in Japan. I would use this company again if I traveled back in Japan.

Great Wifi access for Japan
We enjoyed our WifiBuddy during our trip to Tokyo, Kyoto and Osaka! It was reliable wifi access with a low cost! It was easy to receive and return the device through airport post box. Thanks for providing this service and making it easy to use for travelers.

Great experience
We are glad we chose this company. Starting from they following up with me to confirm the name spelling to avoid troubling from picking up at the airport. The signal was strong with this Diamond Plan. Easy to use, return envelope was included to trouble free when returning the package. Will choose this wifi service again with my next Japan trip. :)
