Cellular issue detected. I cannot make phone calls or receive phone calls or use cellular data.
I contacted my service provider, they had me reset the net work settings. That did not help. So they sent me a new Sim card. For a day it worked, but then the problem reoccurred.
What should I do?
iPhone 7
Make sure you are running the latest iOS 15.7.3
Then see this: If you see No Service, Searching, or SOS on your iPhone or iPad - Apple Support
And finally try resetting your iPhone but don't forget to make a back up and remember your iCloud login details.

When I tried "Erase All Content and Settings", the following message comes up:
"iPhone Requires Service. You will not be able to set up this iPhone after erasing. A cellular update is required before it can be activated again."
So I am not sure how to get the Cellular update and I am afraid to continue erasing everything.
In that case, you should contact Apple
