Great service, very handy!
Pick up was easy, reception was great even underground, and battery life was never an issue thanks to the portable battery.

Good Quality Internet
The device seemed to work everywhere and had decent bandwidth. The battery life could be better but the provided backup helps with that. It restarted randomly a couple times which was annoying.

The wifi reception was great
The wifi reception was great from Tokyo to Hiroshima, battery lasted forever, and the backup battery was handy for recharging not only the device but phone as well. Thanks!

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.
