So easy to use
Everything went smoothly and we had a consistant and fast wifi connection throughout our trip. Pick up was very easy -- there is a desk at the airport and JapanWifiBuddy will send you a map to help you located it. Returning the device also went smoothly. You simply need to put everything back into the reinforced envelope that they send with the original package. You can drop of the package in one of the red post bins at the airport right before you go through security. Customer support was fast to answer any questions I had and to change my order details. All around great experience and it was hassle-free so it was worth the cost!

surprisingly stable and stressfree
We used the Diamond WiFi for our 17 day trip to Japan. We passed through Tokyo, Hakone, Nagoya, Kyoto, Nara and Osaka with some time in the wild nature. Only in Nagoya the WiFi experienced some restarts and disconnects, but afar from that the performance and connection was plain perfect. It carried us through our trip. Highly recommended. Price was also decent for that time range with 4 people.

  • We include thorough instructions, via email, through our website and with customer service.
  • These are data-only SIM Cards. Carrier-based voice calls and text messaging are NOT supported. However, data-based messaging and telephony solutions such as Skype, Facetime, Whatsapp, Line etc. are supported.
  • To avoid provider validation complications, in some cases when users order far ahead of their actual trip, we will send a confirmation email, with a separate QR code later on, closer to the departure date.
