Fast and reliable
I used the Diamond WifiBuddy for the better part of a year, and found the service consistent and reliable. The team also do a great job at ensuring delivery if you can't collect at the airport (they'll pick your nearest post office and send you a detailed map). Will definitely use again.

Fine when it was working
When the wifi was working the signal was great, but it would often shut off- even if the battery was fine. We repeatedly had to restart it because it would disconnect from our phones.

Always has a great connection
This was my 3rd time renting a pocket wifi from this company, the speed is always great and I've never run into connection issues anywhere in japan. Would highly recommend!

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.
