Friend in NJ has a prepay with Verizon on her flip top (simple) cell phone. The contract allows unlimited texting (I believe, texting for sure) and per minute voice. She has been given an iPhone 6, don't know why, and I'd like to move her existing Verizon account over the the iPhone 6. Does the iPhone 6 work on Verizon CDMA? Is there any difference GSM and CDMA in 4th Generation interface anyway? Sorry if I'm mixing up, simple question is if the SIM fits can I simply move it over to the iPhone 6, if not, with the Verizon Store (brick and mortar) make move her account over to her iPhone 6? I understand older iPhones may need an "unlock".. not sure about the "6" model. Welcome input including advice if my question does not make sense. Yes, we plan to stop in a Verizon store, but it is nice to know what to expect.
