A method at a user equipment to facilitate activation and splitting of data billing between at least two parties, the method including starting, at the user equipment, a virtual subscriber identity module platform (VSP) service on the user equipment; verifying VSP configuration information with a network server; upon verification, starting a data networking access point name (APN) based on the configuration information on the user equipment; and setting a status indicator on the user equipment to indicate the VSP service is enabled.

A system and method for generating Call Detail Records (CDR) to optimize network usage notifications to a mobile device subscriber. The system and method can include a billing system module that determines CDR generation parameters for the mobile device subscriber based on the mobile device subscriber's network usage, including increasing CDR generation when the mobile device subscriber's network usage relative to a predetermined quota is high and/or decreasing CDR generation when the mobile device subscriber's network usage relative to the predetermined quota is low. The CDR generation parameters can be applied to control CDR generation for the mobile device subscriber.

A IP telephony service allows customers to form user groups. Each user group can include multiple members, each of whom have their own telephony device. When a member of a user group sends an outgoing communication from one of the telephony devices associated with the user group, the service obtains communication handling instructions for the user group. The outgoing communication is then processed in accordance with the handling instructions. This could include sending copies of the outgoing communication to the telephony devices of other members of the user group. This could also include sending the outgoing communication with an origination identifier associated with the user group, rather than an origination identifier associated with the member's telephony device.
