What does [Err Temp: 0020] mean?

My iPhone 11 Pro Max showed an error screen with the text "Err Temp :0020" two times in the last month and, in the corners: Back, Accept, Cancel.

What kind of an error is this and how to get rid of it?

Thanks in advance.

iPhone 11 Pro Max, iOS 15

Greetings mr_rawa,

Welcome to Apple Support Communities. That message indicates an issue with your wireless service. You will need to contact your wireless carrier for further assistance. We hope this helps you.

Take care and be safe.
