Hello, I have an unlocked verizon iphone 7 purchased in-applestore at full price and I would like to know the differences between the model I have and the sim-free model (knowing that both are model a1660 CDMA and GSM): sim-free model does not hace a sim inserted (sim-free, obviously). sim-free model does have the SIM-eject tool. Can I return mine for the sim-free? (I am still in the 14 days return) Does it worth returning mine for the sim-free? What should I do? What you would do? Thanks, Regards.
