Great
Was waiting for me at my hotel, with return postage and battery pack. Came in a nice little package. Worked great for everywhere we went; Osaka, Kyoto, and Tokyo. Highly recommend.

Diamond WifiBuddy Rental
Clear instruction on how to pickup from the airport. Great connectivity for my whole trip throughout Japan (Tokyo-Hakone-Kyoto-Osaka). Easy instructions and packaging on how to return via mail at Narita airport. 100% will use again and recommend to friends.

Best purchase for the trip!
The experience with WifiBuddy was seamless. Easy to order, cost-effective, and worked well. Arrived at my hotel and it was waiting for me along with a back-up battery and envelope to mail back (easy to use the post office at Narita Airport). The charge lasted most or all of the day depending on use and having the back-up battery on hand was helpful. We only had an issue one day where coverage was spotty and had to reboot and then it was fine.

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.
