I'm getting the error "This code is no longer valid

This error usually means one of two things: the eSIM has already been installed, or there's a problem with the QR code or activation code itself.

First - check if your eSIM is already installed

  • iPhone: go to Settings → Mobile Service and look for your Gohub eSIM in the SIM list
  • Android: go to Settings → Connections → SIM Manager and check if it appears there

If it's already there, your eSIM is installed - you just need to adjust a few settings to get connected.

⚠️ If your eSIM was previously installed and then deleted, it cannot be reinstalled. Contact Gohub support immediately.

If this is your first time installing, try the following:

  1. Check your QR code or activation code - make sure it hasn't expired and is the correct one from your confirmation email or Gohub app
  2. If entering manually - double-check for typos, extra spaces, or incorrect capitalization
  3. Disable any VPN on your device
  4. Switch to a stable Wi-Fi network - avoid public or ship Wi-Fi
  5. Remove any eSIMs you no longer use to free up space
  6. Make sure your device software is up to date
  7. Try a different installation method - if QR scan didn't work, switch to manual entry, or vice versa

If the error persists, contact Gohub via WhatsApp - our team can verify your activation code and reissue a new one if needed.
