iMessage and FaceTime stopped working after switching iPhones because your new iPhone has not completed activation.

Fix by:

  1. Signing out old device from iMessage/FaceTime
  2. Turning iMessage/FaceTime off → on
  3. Testing SMS
  4. Checking date/time
  5. Removing VPN
  6. Resetting activation tokens
  7. Resetting network settings if needed
  8. Asking carrier to refresh SMS profile if activation still fails
