Hi i have someone who came to me some few minutes ago with same issue

We exchanged sim cards of the same carrier and it worked

Try inserting your simcard in another phone and also put other's sim cards in your phone and then put back yours, atleast restart your phone 1st,, it might sound crazy but it worked

Resetting network settings can fix configuration issues:
Settings > General Management > Reset > Reset Network Settings.
