Abstract
An identification module (such as a SIM card) for securely providing a mobile identity to a mobile data network for use in identifying mobile equipment in which that identification module is installed comprises a mobile identity memory which securely stores data defining two or more different mobile identities; a selector for selecting a mobile identity from the two or more mobile identities; a network interface for generating data derived from the selected mobile identity for transmission to a mobile network during a network authorization procedure, and for receiving acknowledgement data back from the mobile network indicating whether authorization was successful based on that selected mobile identity; and a detector for detecting whether the acknowledgement data indicates an unsuccessful authorization with the mobile network and, if so, for initiating a further network authorization procedure in which the selector selects a different one of the two or more mobile identities.
