switching from Verizon to AT&T
I'm currently with Verizon. i owe a little over $300 left on my S 21 ultra phone. i wanted to switch services providers because Verizon is lawful. i have a couple questions
1- does at&t pay off whatever i owe to Verizon upon switching to at&t????
2- how much do i have to pay up front for the new S22 ultra phone i want to get at at&t or do they just bill it to my first bill.
3- it will be only one line if i something to at&,t
4- can i always keep my same phone number that i currently have upon switching to at&t??????
