Some Mobile Virtual Network Operators (MVNO) carriers. Like tracfone, boostmobile, consumer cellular, etc can push updates and reboot your phone whenever they want.
They run by piggybacking off the major networks but in their contract terms they essentially own your phone, even if you make use of their Bring Your Own Device (BYOD) options. So it's not AT&T doing it, its the MVNO which you signed a contract with to use their network.
Actually, they all probably do it even the major networks, regardless of whatever setting you have on your phone.
