Great Wi-Fi service
My friend and i used Japan WifiBuddy for our 20 day trip. We had a no issues and was connected to the internet the whole time. We loved how it came with an extra power bank so we didn't need to drain ours. Pick up was also easy. I was sent very clear instructions via email a week before we landed and picked it up at the counter which was easy to find at CTS airport. Thank you Japan WiFiBuddy for always keeping us connected!

We are an Australian family of 5 who just spent 16 days in Japan travelling extensively. The wifi buddy was awesome. It allowed us to remain online the whole time. We really needed it for getting around using Google maps. In my opinion it's the best money we spent in Japan. Wifibuddy was cheap to rent, small, easy to carry, worked consistently and I would definitely recommend renting one if your travelling around Japan.

Second Rental
Very good overall. Still highly recommend. Our pocket wifi kept timing out and we'd have to push the power-button to re-initiate it once every 3-4 hours, but other than that overall was very good! Easy pick-up, easy return, and amazing customer support.

Perfect service
It was not my first time using a WifiBuddy and it's certainly not the last!

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.
