Good WiFi router
Good WiFi router but do make sure you have an extra rapid charge battery as it runs out if juice

The pocket WiFi saved me,
The pocket WiFi saved me, and worked super well for the most part. It would be better if the battery life lasted a little longer. The portable battery that came with it also did not work very well after a week of consistently using it and charging it each night.

Great overall
Reserved online, was ready to pick up from the Post Office soon as I got into Narita, speed overall decent but sometimes very slow even for 3G, coverage good and most places we had signal. Overall fast, convenient and good value for what was paid and would recommend to others

Excellent service
I ordered a Diamond WifiBuddy for 13 days, on 2 mobiles and it never failed me at all throughout our travel. I will definitely recommend the website to those visiting Japan and won't hesitate to use them again when we go next time

Excellent
Worked everywhere I went and was very fast and reliable! I constantly had maps open with two devices connected at the same time, so the pocket wifi often drained quickly and gets hot. However, with the portable charger, the device easily lasts all day. Return and pick up was easy. Will definitely use again.

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.
