Great coverage, easy to use, great customer service
The wifi device worked perfectly, I had 3 devices connected at any one time and the speed was amazing. It came with a back up battery which is for the best because under heavy usage the battery on the device isn't great. 100% Would use again

Great WIFI service
Used Wifibuddy’s service for 17 days starting 9 May 18. Great 4G speed with no drop outs and always had 4G service throughout my travel in Tokyo and Osaka. Highly recommended!!

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.
