Worked brilliantly
Encountered no problems with our recent hire for a 3-week trip in Hokkaido. From downtown Sapporo to various (not too remote) mountain summits, the device didn't miss a beat. Picking up the unit at CTS was quick and simple, and set-up worked pretty much as explained on the enclosed instruction card. Only caveat would be that the unit didn't last a full day on some days, so had to recharge every night, but that wasn't a hardship. Would use again; completely satisfied.

Easy access to WIFI in Japan
This is my 3rd time using Japan WIFI buddy services and I absolutely loved it! The process is simple! They send it to you for your arrival and provide a mailing envelope for return. Will be using again next year!

Wifi Rental
Wifi Buddy was great to have for our 12 days in Japan. it was there at my hotel when I arrived and i just posted it at the airport when I left. Didnt have to worry about finding Wifi when we were out and about. Very convenient and easy to use.

Painless rental.
Picked up item at Narita and returned it there before departure. Device lasted about 7 hrs before requiring backup battery but worked flawlessly.

Specifications
  • Requires a SIM Unlocked device with esim capability. If your device is locked, please contact your carrier to unlock 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.
  • 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.
