I honestly don‘t know what we would have done without the Wifi Buddy. The device is very reliable wether you are at Shinjuku Station or on the fifth stage of Mt Fuji.

Worked very well, however, was very very slow at some points even when just trying to open a webpage. Other than that it was a great pocket Wi-Fi.

Easy, cost effictive wifi
18 days in Japan and the wifi buddy was an invaluable asset to the holiday. Wifi Buddy delivered to our hotel when we arrived in Japan and we used it constantly. Easy to use and the additional battery was extremely useful. Packaging to return wifi Buddy was included and we posted the wifi buddy at the airport as we left Japan. I would highly recommend Japan Wifi Buddy.

Quick Setup Guide

  • 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.
