What it is

Cell broadcast is designed to deliver messages to multiple users in an area.

This is notably used by ISPs to send Emergency/Government alerts.

Runs at boot time and is also triggered after exiting airplane mode.

Commands

adb shell pm uninstall --user 0 com.android.cellbroadcastreceiver

To put it back:

adb shell cmd package install-existing com.android.cellbroadcastreceiver

Every removal listed here is per-user only: the system image is untouched, and the restore command puts the app back from the copy already on the device. Nothing is downloaded.

This is not the directory. Here we say what a package is in general; what happens on your particular television is on your model's entry, and that one wins. The same package can be dead weight on one set and hold the home screen up on another.
