Imessage Won't Work on Phone
I am trying to send an iMessage to my daughter and the iMessage says I'm signed out via an email I HAVEN'T USED IN 4 + YEARS and I tried to reset on iPhone with my iCloud User ID and PW and it it's saying it's not able to verify ****. I need my iPhone i Message to work because I expect to get boarding passes via A TEXT from my airline in 1 day and I am OUT OF TOWN. The level of my frustration far exceeds the caps I have used here.
iPhone 6s, iOS 10
