Diamond WifiBuddy
Pro Tip: order a wifibuddy! If you've scoured the internet about pro tips, one of them is to order a portable wifi -- that's because not a lot of restaurants/public places with free wifi. From ordering, pick up, and drop off - the process was very easy and convenient. We picked up the wifibuddy @ the aiprort, the package came with a return envelope, extra portable charger, and wires. The downside is the battery life but if you bring an extra portable charger, you're good to go! The connection was great! We traveled to Kyoto, Hakone, and Tokyo. Didn't have an issue at all. Would highly recommend!

Great Rental Experience
The entire process of renting from JapanWifiBuddy was so convenient! Picking it up at the airport post office was easy and everything was packaged into a zip up pouch. Wifi speeds were fast too.

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.
