Physical SIM Network Not Available
My settings indicate that my physical SIM network is not available, phone not allowed.
The SIM card is functional, tested it in other phones.
I have tried ALL the recommended fixes I could find online (airplane mode reboot, turn-off phone reboot, remove/reinsert reboot, etc.)
Phone was in network several days ago.
Carrier has pinged SIM card twice to reset network, still not functioning.
I am up-to-date with carrier account.
Appreciate any suggestions to resolve this specific issue.
