Switching from iPhone SE to 7plus. says that that the ICCID you entered is already in use
Bought an iphone from my girlfriend, who uses verizon, after she got an upgrade. The phone is unlocked and should be compatable with virgin mobile. When I try to register it with virgin mobile however it says that the ICCID code I entered is already in use. As for the phone itself, when I put the sim card into it, it'll work for a couple minutes and then say the Sim is invalid. How do I get this phone to work under Virgin Mobiles service?
