At my middle school, we also banned smartphones throughout the whole building. You were meant to either leave yours at home or put it in your locker when you got there. It’s a lot easier to chat with people during the breaks when they’re not face-down in their phone screen.
They were always collected when not in use. We don’t get personal devices, we either go to the computer room, where every screen can be seen by the teacher at once a la panopticon, or we get a trolley full of laptops that we hand in at the end of the lesson. You can also BYOD that isn’t a smartphone, so long as you don’t use it during lesson time when the teacher doesn’t permit it.
