How to set up iMessage?

Process for iMessage Setup

1. Preliminary Checks

  • Make sure the MUCHO eSIM is activated and selected as the primary line for calls/SMS.
    • Réglages > Données cellulaires > Ligne par défaut = MUCHO (ou Principal ou le nom que vous avez donné à la SIM MUCHO)
  • Check that the MUCHO line can send SMS (required to activate iMessage).
  • Check that your Internet connection (Wi-Fi or 4G/5G) is working.

2. Disable and Re-enable iMessage

  1. Go to Settings > Messages.
  2. Deactivate iMessage.
  3. Restart the iPhone.
  4. Return to Settings > Messages and reactivate iMessage.
    ⚠️ The iPhone automatically sends an international SMS to Apple to activate iMessage. This is usually immediate, but can take up to 24 hours.

3. Check MUCHO number association

  1. In Settings > Messages > Send and receive.
  2. Check that your MUCHO number appears and is ticked.
  3. If only the Apple ID email is checked → wait a few minutes or repeat the deactivation / reactivation process.

4. Do the same for FaceTime

  • Settings > FaceTime > Deactivate / Reactivate.
  • Check that the MUCHO number is ticked in Reachable at.

5. Troubleshooting steps (if unsuccessful)

  • Vérifiez que la date/heure est réglée en automatique.
  • Make sure your iPhone is up to date(iOS).
  • Remove and reinsert the (e)SIM (or reboot after activation).
  • If still blocked: contact MUCHO to check that the line can send/receive SMS, or Apple Support if the problem persists on the Apple activation side.
