Easy, fast and convenient
This was my first time using a pocket wifi system, and it was a BREEZE! Japan Wifi Buddy give you everything you need for a fast connevtion, and supported seven people very well on a two week trip.

Excellent!
Was in Japan for 3 weeks with a group of friends, and it worked great as a proxy for phone services. Would definitely use again if I take another large trip to JP.

Great Service
Overall the WifiBuddy had service everywhere I went and was exactly as promised, the only exception was the battery life. I used hotel WiFi in the morning and night, but around 13:00 the WifiBuddy would die every day. I had brought my own very large battery charging pack, so no worry. Plus, they included a small backup battery too.

Absolutely no problems, saved us
Absolutely no problems, saved us a bunch when the hotel’s WiFi had no signal

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.
