I thought a sim card was a card you put in a non verizon phone. (my uncle had a AT&T phone that he had a sim card and he could take it out of his phone and put it in any phone and it automatically worked on his line.) I have been with verizon sence they started and I have never had a sim card. There are SD cards but they have nothing to do with activating your phone. So why are people talking about sim cards to use there verizon phone on verzons network. I always had to call or go on line to activate any phone I like on my line. when you get a new phone from verizon all you do is dial *228 and option 1.
