Working as intended
Battery life was good and the extra battery provided came handy once. The reception was sadly quite bad the second you went inside buildings (Kansai area).

True Unlimited and ease of use
I rented the diamond service for a month in Japan and had no issues at all. There was service everywhere I went from Tokyo, Tohoku and Hokkaido. I would recommend this for serious photographers wanting to backup photos without having to carry a laptop around with them.

Effortless
Don’t bother getting an international cell phone plan! The WiFiBuddy had us connected to text messages, FaceTime audio and work email for our entire trip. Thee router was at the hotel when we checked in and the hotel concierge happily mailed it back at the end of our trip. No stress whatsoever!

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.
