So easy and reliable

Diamond device was perfect. Speeds were pretty good. Pick up and drop off at the airport were very easy.

I used the diamond wifibuddy

I used the diamond wifibuddy for 1 year straight and had very few problems at all. Anytime I did have a problem it was not at the company’s fault and JapanWifiBuddy was always fast to help resolve the issue and take care of me as a customer. Truly 10/10

Trip saver

Cannot imagine our trip without it. Convenient, fast, reliable, fair pricing. Only wish is that the battery could truly last a full day. We usually started our day early and were running low on battery by late afternoon. The backup battery bailed us out in those cases.

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.
