Important Notes

  • Manual Access Point Names (“vmobile.jp”) entry may be required. If not tech-savvy, choose our Japan eSIM with automatic APN
  • Scanning the QR code activates your plan and starts the first day

Troubleshooting Guide

eSIM not working? Don’t stress! Follow this guide to get you up and running.

  3. Confirm mobile data is sourced from our eSIM (i.e. the correct eSIM profile is selected)
  4. Turn data roaming on (Android: select all network)
  5. Wait up to 10 minutes for activation to occur
  6. APN: vmobile.jp | Username: [blank]  Password: [blank] (Android: select manually)
