That is super odd! I am not seeing anything about this internally. I know this might sound trivial, but have you tried removing the SIM card and putting it back in? Can you get me a link to where this was posted on Apple's forums?

Hey, @ironbear119 and @nperez2008​!

Can you try following the steps listed here: If you get an alert about the SIM card in your iPhone - Apple Support  to see if that helps? Please keep us posted!

The same issue I was faced when I trying to update 6S with iOS 12. And There was an error connecting to the apple id server and ID was log out automatically. It was not responding when I insert log in details.

Hmmm. Are you able to send me a screenshot of the error? Is there any way that you were able to work around the error or get it to go away?
