Or subsidized on contract? Order from Best Buy online ship to home. Best Buy is now selling "SIM-free" iPhones that follow the US Reseller Flex Policy. They are no longer selling the carrier models at least that is true of the iP7/7+. This explains why the SIM cards are not in the devices!! This has always been true of the iPhones purchased from Target and Walmart, btw. These are identical hardware-wise to the Verizon/Sprint models with the Qualcomm modem. But they will follow the unlocking policy of whichever carrier's SIM card is in the device during the initial activation. If you order your AT&T iP7/7+ from bestbuy.com, it comes with a SIM card that is not in the device. If instead of using that SIM that ships with the phone you use a Verizon postpaid SIM to initially activate the device, the device will follow Verizon's unlocking policy, which of course means it will be unlocked. You can then put your already active AT&T SIM in the device and it will work fine on AT&T and be unlocked. Your device will have the Qualcomm modem. For Sprint, you can do the initial activation with a Verizon postpaid SIM and then can use the Sprint SIM card that shipped with the devivce to activate the phone on your Sprint line. But if you did the initial activation with a Verizon postpaid SIM, the device should be unlocked nonetheless. I don't think you even need to use an active Verizon postpaid SIM for the initial activation; I think you can use an inactive one and activate over WiFi. Just don't use a Verizon prepaid SIM. And for Verizon customers, the same is true so make sure that you use a Verizon postpaid SIM to do the initial activation. If you do not do that, your device will follow the unlocking policy of whichever carrier's SIM card is in the device during the initial activation. There has already been a report of a very sad Verizon customer that used a TMobile SIM to initially activate his Verizon iP7 - the phone is now locked to TMobile!
