I got a new iPhone 6S+ under a renewed 2-year contract with AT&T. I have not activated it yet (still sealed). Has anyone had luck with getting phones unlocked without activating them? I'm assuming that the phone is tied to AT&T even though it's unopened? I was wanting to give it to my husband (he has T-Mobile) and just keep my 6+, but I don't even know if that's feasible. I did try the unlock request a few times but keep getting "This device is not eligible for an unlock at this time." Any way around this? TIA.
