Very efficient procedure, works as designed
We rented the Diamond Wifi router and everything went very well: seamless delivery at the airport, very easy usage (switch it on, insert WPA key in your phone and done). We got network access everywhere we went and the return procedure as easy as the delivery: we just gave the return envelope at the Narita T1 post office and they took care of everything. Only small issue is that we weren't able to make a full day of usage without connecting the backup battery, generally near the end of the day, but otherwise perfect little device and great service.

The Best
It was my second time to Japan and like the first time, I never had a problem with my diamond plan WiFi unit. I was able to take it everywhere and it would work great! I highly recommend this plan if you’re planning to go all over Japan.

Fabulous
We were three people logged in for two and a half weeks and had constant service everywhere. It worked in the cities and the country, even on our hikes. We used the back up battery on days with heavy usage. It was waiting for us at the hotel when we arrived and we dropped it into a post office box at the airport before leaving. Could not have been easier, we highly recommend it!

  • 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.
