iPhone 12 mini SIM cards disconnecting from Verizon network

Both my wife and I have IPhone 12 mini's. At the same time last night both our SIM cards disconnected from the phones. I re-seated both our cards several times and they both came back. This morning my SIM card disconnected twice. I re-seated the SIM card again and also blew out the SIM card slot with compressed air. So far it seems to be holding, but I'm not confident it will stay connected.

Seems awfully suspicious that both our SIM cards disconnected at the same time.

No updates came through last night. Both our OS are at 18.3.1 and have been updated for awhile. We are on the Verizon network.

Anyone else having this issue?

Thanks for the quick reply.

I checked for carrier updates and there are none.

So far the SIM cards have not disconnected again. Crossing my fingers
