Satisfied customer
We ordered our Pocket wifi from WiFi Buddy online and received an email confirmation immediately. A representative contacted us to confirm our details and provided all the necessary information, including a map of the pick up location. We picked up our pocket wifi from Kansai airport without any fuss or problems. After we finished, we posted it back using the pre-filled Express-post envelope that was included in the package. Overall a very positive experience with great service and value. I would highly recommend.

Thankful for WifiBuddy!
Japan WifiBuddy was easy to set up and for the most part I had WiFi everywhere I went in Tokyo. It was great for my first trip to Japan. I appreciated that they also included an extra battery. I would definitely use this service again. Highly recommend.

Keep connected
Wifi buddy is definitely a great buddy and kept me connected while I was traveling overseas. It was also small enough to keep in my purse. I would recommend it to everyone.

Quick Setup Guide

  • 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.
