iOS 12 messed up my carrier settings. How do I fix it?
This article makes no mention of how to actually help fix the issue. I have restarted my phone. Taken out the SIM card and put it back in and while restarting my phone. I reset the network settings and nothing works. Please tell me what's wrong and how to fix it? And quickly because I need my phone for both work and school. Thank you.
iPhone 7, iOS 12.0.1, I'm mad.
