This is due to an eSIM issue with your model on AT&T's servers.

While there is an AT&T issue, I signed up for a 30 day trial of T-Mobile and there have been more than a few times while in known good cell service areas I am seeing SOS for both eSIMS on my 18 PM. 🤷♂️
The Apple Store ran diagnostics on my device and all tests came back healthy.

This is an AT&T issue and you'll need to wait for them to resolve it. It's not an Apple issue. And oddly enough, it doesn't affect everyone on AT&T. But it is an AT&T issue.
