Abstract
A system provides a service to mobile devices that permits the mobile devices to substantially avoid roaming charges while roaming in visited networks. A temporary subscriber identity (TSI) server receives a TSI request message from a TSI client operating on a roaming mobile device. If available, a temporary service identity is returned to the TSI client, which registers the mobile communications device with a specified service provider as a home subscriber using the temporary service identity.
