I changed from AT and T, to Spectrum mobile and purchased a new 12. Voice over and I thought the icloud were going ok. As of now, no signal, she assured me i have service, I can't even see my phone number in my facetime settings. I want to clean up the older phone because i'll sell it. I tried to download alex but it won't switch over even though I thought it was selected. Not goot at face ID or the home gesture but this is four hours old. Help please.
