Abstract: Systems and methods for cost-effective phone calls and dynamic provisioning of mobile profiles within a roaming environment are presented herein. A platform component stores multiple profiles for a mobile device and can dynamically reroute incoming phone calls to another profile using a database of stored profiles and a rerouting component. The phone call is rerouted from a first identity of a mobile device that is associated with a first network, to a second identity that corresponds to the second network that the mobile device is roaming in enables the mobile subscribers to bypass the high charges associated with roaming. Furthermore, a roaming platform component can perform location updates on a mobile device, thereby updating the identity of the mobile device's SIM card to ensure that the mobile device has an identity profile that corresponds to a visited network in which the mobile device is roaming.
