Yes, I tried almost everything.

  1. Unregistered and registered iMessage (Several times)
  2. Restarting the phone (Several times)
  3. Resetting the network settings (Several times)
  4. Contacted the (Carrier) customer care (Several times)
  5. Contacted apple support (3 times by now)
  6. Reset the whole iPhone (extreme step)


NOTHING has worked so far. I still see that red exclamation mark and message not delivered error.


Also, I inserted the same SIM to another Android and iPhone through which I was able to send both iMessage and Text message.

If I insert some other SIM to my iPhone I was able to send both iMessage and Text message to another number.


Basically, I am super confused on whom should I contact now? Apple Support or Carrier service...
