The disclosed technology automatically terminates wireless service that a mobile communication network provided to a telematics unit, e.g. when the customer is no longer active for telematics service. The disclosed deactivation allows the network service provider to reuse any resources, such as mobile numbers, that were previously assigned to the particular telematics unit. In a disclosed example, a SMS deactivation message causes the telematics unit to delete its mobile provisioning data, such as its MDN and/or its MIN, and replace that data with a dummy number. The deactivation procedure may also provide a replacement destination number for emergency calls, typically a cleared number, such as 911. For example, the deactivated telematics unit would be able to call a PSAP, and the PSAP would recognize that the unit is inactive for wireless service (and cannot be called-back) from the dummy number used to identify the unit.

What is claimed is: 1. A method of deactivating a telematics unit with respect to communication service through a wireless communication network, comprising steps of:receiving a request to deactivate the communication service through a wireless communication network in a system of an operator of the wireless communication network from a telematics service provider, the request identifying the telematics unit;in response to the request, generating a deactivation command message for the telematics unit, the deactivation command message containing a dummy mobile number indicating that the telematics unit is not activated for communication service through the wireless communication network;transmitting the deactivation command message from the system of the operator of the wireless communication network, through the wireless communication network to the telematics unit;receiving the deactivation command message in the telematics unit from the wireless communication network;responsive to the received deactivation command message, deleting a mobile directory number (MDN) or a mobile identification number (MIN) number assigned to the telematics unit by the operator of the wireless communication network for authenticating the telematics unit for communication through the wireless communication network when the telematics unit is active for wireless service, from storage in memory of the telematics unit; andstoring the dummy mobile number from the received deactivation command message in the memory of the telematics unit in place of the deleted number for use in a future attempt of the telematics unit to communicate through the wireless communication network when the telematics unit is inactive with respect to communication service through the wireless communication network.
