And of course that's not possible with lots of newer devices. Taking the SIM out may help.
Incidentally, I'm told that on some models the "find your phone" functions can track the phone when switched off, and in some cases turn it on and take a photo etc.
I know that some phones can be activated remotely by the corporate admins in order to install software updates or perform a security wipe and permanent deactivation. The fact that this is possible shows that even when "switched off" the phones are running, connecting, receiving data and executing commands, at least intermittently.
