Mobile error 1035 causes the phone not to work
I’m working on a friend’s iPhone 12 Pro. He’s not very helpful to me because of memory issues; however he switched his carrier from Verizon to consumer cellular a couple of weeks ago and the phone portion of the iPhone ceased to work (email and messaging both work).
the error code is 1035; voice mail needs to set up. I’ve tried that with no luck. What next?
