Japan Wifi Buddy was a lifesaver!
I loved how easy it was from start to end using our Wifi Buddy. I purchased the diamond package which was so reasonably priced & worth every cent. An envelope containing the wifi buddy, chargers, instructions & additional battery were at our hotel upon arrival in Tokyo. We were never lost and carried the charger with us, stopping at a cafe if we needed to recharge. I also turned it off when not in use to conserve battery power. We never would have seen nearly as many attractions without wifi Buddy. On our final day, I packed everything back into the pouch and the reply paid envelope & posted it in the hotel post box. Super easy! Thanks so much Japan wifi Buddy!.

Fast and reliable internet, convenient pickup/drop off
Picking up the WiFi dongle from the airport was convenient and stress free, internet speed was lightning fast and made getting around Japan magnitudes easier. Dropping off the WiFi at the post office took only a few seconds. Couldn't be happier with this service.

Customer service
The customer service waa amazing, they stay in contact with you to make sure everything is set up perfectly before your arrival. The device is small but can get a little hot in your pocket, better to leave it in a handbag. The internet speed was good and the reception as well.

Highly recommend
Super fast, unlimited wifi and worked everywhere we went! We saw so much more of Japan because of this device. We were able find all the tourist attractions nearby while we were out and about. Well worth the price, highly recommended!!
