I'm trying to activate a prepaid Apple SE phone purchased elsewhere, deactivate my current Motorola phone, re-use the Verizon phone number I currently use on my Motorola phone, and signup for a pre-paid plan I tried "switch devices" online and failed with an error message saying it couldn't be done online and to call a number. The phone call failed- no understanding of what I wanted done. Back online, I tried the Prepaid plan menus and got further but in checking out , it asked me whether I wanted to keep my number. I said yes, entered it, and got an error message saying that the number I entered is already active and indicates I am already a Verizon customer ( which it knew since I had checked that that AND was signed in) and to please verify or submit a new number? It basically stopped the process. Should I have tried ( if possible) to deactivate my current phone first? Or should I just go to a Verizon store?
