iPhone can't call or receive phone calls or receive data
Updated my iPhone 6s on 09 13 2020 to iOS 13.7 when it was finished it had error message saying that I would not be able to make or receive phone calls or receive data. I've tried everything that I know to get it back to no avail. Anybody else have this issue when you updated your iPhone if so did you fix this problem?
iPhone 6s, iOS 13
