A couple of days ago my iPhone 7 started to show 'No Service' error in the upper left corner of the screen. Tried several ways to fix this but nothing helps. While trying to reset it I got the error message:

title: iPhone Requires Service

body: You will not be able to set up this iPhone after erasing. A cellular update is required before it can be activated again.

What does this mean? Is it safe to proceed?
