AT&T Lumia 640 on Cricket
So I've been thinking about buying a Lumia 640 as a gift for someone, they're currently on Cricket Wireless. I saw that Microsoft and Best Buy both had a deal on the Lumia 640. However, these are AT&T branded Lumia 640's. I know Cricket is owned by AT&T and uses AT&T towers, but is this phone still carrier locked to AT&T? Or will it work on Cricket if we put a Cricket SIM inside the phone?
