A device profile manager receives notification of a user operating a mobile communication device in a subscriber domain. In response to detecting authorized usage of the mobile communication device in the subscriber domain, the device profile manager initiates registering of the mobile communication device and/or corresponding non-head of household user for subsequent use of incremental subscription services assigned to the subscriber domain. Subsequent to auto-registration of the mobile communication device to use services associated with the subscriber domain, the non-head of household user operating the mobile communication device is able to use the incremental subscription services assigned to the subscriber domain based on the identifier value of the mobile communication device without submission of access credentials.
