My phone number won’t connect to Apple ID — iMessage, FaceTime, and SMS not working

Hi everyone,

My phone number won’t connect to my Apple ID — iMessage, FaceTime, and even regular SMS messages don’t work. I’ve tried using other Apple ID and even replaced my SIM card, but nothing helps. I’ve also tried turning iMessage and FaceTime off and on, checked my number in and I have a working mobile plan but nothing works.

Would deleting my current Apple ID and creating a completely new one possibly fix this issue?

Any help would be much appreciated!
