The Cellular Manager (CellularMgr) controls the way a device's cellular data connection is used. This CSP is supported only on Zebra Android devices equipped with a Wireless Wide Area Network (WWAN) adapter and access to a cellular data network. Attempts to use the CellularMgr on unsupported devices returns an error in the Result XML document.

The CellularMgr provides the ability to control the State (active/inactive) and Usage (enabled/disabled) of features. An option's "State" can be thought of as an "On/Off" switch; the feature is available to the device user and apps to make active or inactive as desired. The term "Usage" would be like a cover over the switch, locking it in its current position. When Usage of an option has been Disabled, the cover is closed and the position of the switch cannot be changed by the user or apps. Enabling Usage lifts the cover, enabling Cellular features to be turned on and off at will.
