Your iPhone 15 voicemail stopped working after iOS 26.1 because your carrier’s conditional call forwarding got disabled/corrupted during the update. To fix it:

  1. Dial ##004# to reset voicemail settings
  2. Dial 004voicemail-number# to re-enable it
  3. Turn off call forwarding
  4. Reset network settings
  5. Update carrier settings
  6. If needed, reinstall eSIM
  7. Or ask your carrier to enable voicemail again

After these steps, voicemail will start working normally again.
