A system and method store provisioning data supporting a plurality of service providers in a VSIM internal memory unit of a mobile device. A user may selectively enable provisioning data supporting one of the plurality of service providers stored in the VSIM internal memory unit to conduct a wireless communication. An embodiment permits backing up, retrieving and restoring personal data in the VSIM internal memory unit using a remote database. Another embodiment allows a mobile device to select an optimal service provider to conduct a wireless communication. The optimal service provider may be determined based upon mobile device location, communication usage request and/or time and date.
