Settings app repeatedly freezes when trying to reset Network Settings on iPhone
I notice after upgrading my iPhone SE (original) to iOs 15.1 that I have no phone service. (It's possible I lost service before the 15.1 update, but that's when I first noticed it.)
Apple's suggested remedies are to try a restart, check coverage, check for a carrier settings update, take out and put back SIM card, and reset Network Settings. I've progressed to the stage for resetting Network Settings. Settings freezes after I put in my PIN and confirm that I want to reset. The only way out is to quit settings.
Any ideas?
