Very smooth handling: pick-up at Haneda, drop-off at postbox, very reliable

Great service!
Awesome service. Email responses were super fast, instructions were incredibly clear, and the pocket wifi was a lifesaver when I was in Japan. Would recommend!!

Super Easy and Convenient
This was my first time using a portable wifi and it could not have been any easier. The ordering process is super simple and the instructions provided with the wifi buddy are very clear. Additionally, the price for a premium was very reasonable. I do not know how I would have survived without the portable wifi on my trip. I highly recommend.

Works great as usual
I travel to Japan about once a year. My portable WiFi from WifiBuddy is always waiting for me at my hotel during check-in. Works great as usual. Have no complaints. The prices have gone up a tad bit however, but its well worth the price and convenience.

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.
