Follow the steps in this support document. If you can’t turn on or sign in to iMessage or FaceTime on your iPhone - Apple Support

If that does not help, you need to contact Apple Support. Use the link at the top or bottom of the page here.

Same here!


I updated my iPhone 16 Pro last week and all was good. I then updated my wife's iPhone SE and Message app broke as described above. Phone number refuses to activate and have had the spinning icon going for over 5 days now.


None of the suggestions in the article referenced by Chris helped. Reached out to Apple Support but have yet to get a reply. Very disappointing.
