No Network after update.

[NationalTrust]

S22+ on Verizon (Locked). I’ve had the phone since launch with no major issues. I received the March update on Friday the 18th. Since then, I have lost my network at least once every day. I get the message “Your phone’s not registered on a network so you can only make emergency calls.” Restarting or toggling Airplane mode on and off will correct it temporarily. I’ve gone into Settings>General Management>Reset, and reset the network settings, but that hasn’t corrected the problem. Anyone else with this issue? What else can I try?

that is something you'll need to straighten out with the carrier.
It could be that Verizon made some mistake excluding details regarding your device to their server while updating or whatever else the reason.
