Excellent & Necessary
You will find lots of free WiFi in Japan. However, when you are off the beaten trail or simply moving from place to place, having mobile WiFi is really, really useful. Especially: maps! Japan WiFiBuddy worked perfectly for us. Picked it up at hotel, good instructions in documentation, postage & packaging included for sending back at the end of trip. We did not run out of data. Only rarely was the WiFiBuddy's signal a bit poor. I highly recommend Japan WifiBuddy.

Good product
Very good and handy product, but it becomes much slower after the 4th day of usage between two phones.

Great reliable device, a necessity if you are on the go in Japan
Hi, I rented the Diamond, had it waiting at the hotel when we arrived. In 10 days we used the device for navigating trains and maps and even watched some netflix during a heatwave. Great connections and speeds, and simple setup and return.

Quick Setup Guide

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.
