I'm trying to buy a Verizon iPhone 5 from some guy and he repeatedly tells me that he will remove the sim card before selling it to me. And that Verizon iPhone 5 uses only sim no CDMA. I assumed all he had to do was inactivate his iPhone 5 and then give it to me with the sim and I would just activate it on my account? Can someone clear this up for me. Should he be supplying me the sim? If he doesn't, can I obtain one from Verizon?
