Awesome and convienient
best purchase ever. Tre was very helpful and you can pick it up at the airport so you have it the moment you get off the plane.

superb service
Fantastic service. The router worked perfectly and without any problems until I screwed it up. Once that happened I had non-stop, immediate and responsive help - in English! Fixed the issue right away. Thanks so much!

a necessity for anyone traveling in Japan!
Having internet access throughout a recent trip to Japan to visit my daughter was indespensible. From email access to searching for travel information, WiFIBuddy gave us the needed Internet access to really enjoy our trip. Signal strength was excellent and continuous, and the unit usually went an entire day on a single charge. Pick up and drop a breeze at the airport as we entired and left the country.

Excellent service from Tre and excellent wifi router! worked well throughout my recent 10days trip to Tokyo and Hokkaido. Spare battery also helped a lot too! I will definitely use this service again when visiting Japan in future. Thank you Tre :)

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.
