An Essential Addition to the Trip
The device was a godsend. Without an international data plan we had no way to navigate the complex cities of Japan. Having access to high speed internet at all times of the day was exactly what we needed to keep in touch with family and friends while offering us directions and restaurant reviews on the fly.

Quick Setup Guide

Specifications
  • 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.
