Hey! With an iPhone 5S that was purchased over the phone with Verizon. Would everyone keep Verizon for their carrier or would someone switch over to AT&T? This applies to both the overall pricing for the plans and the network coverage. Also, if I wanted to switch from Verizon to AT&T even though I am not getting a new phone with AT&T, but they still do a credit check and mine came back that I have to pay $100, so basically I have to pay the $100 than they will send me out an AT&T SIM card. Not sure why?
