Hi guys, I've never ported a number before, just have a few quick questions. The number I want to port is the primary number on a family plan with Verizon. I want the other numbers on the family plan to remain with Verizon; I just want to move mine to AT&T. Before porting, should I call Verizon and tell them to make another number the primary number--so as to prevent any confusion later on when AT&T is moving the primary number? Or does this not make a difference? Also, what am I supposed to do with my current phone that I have with Verizon? Once the number gets moved to AT&T, the phone will become useless right? Do I have to return the phone to Verizon? Thanks!
