Abstract: A method of registering a telematics unit for telematics services is disclosed. The method comprises a mobile communication device of a subscriber contacting a mobile network operator (MNO) to register a telematics unit (TU) of a vehicle for telematics services, wherein the mobile communication device provides a vehicle identification number (VIN) of the vehicle that the TU is associated with. The MNO looks up a phone number of the TU based on the VIN. A mobile communication network sends an electronic message to remove incoming voice call blocking of the phone number. The MNO then places a voice call to the unpublished phone number of the TU. The MNO then validates the subscriber. The MNO then engages in a voice dialog with the subscriber associated with the vehicle via the TU. The mobile communication network then sends an electronic message to reestablish voice call blocking of the TU.
