<p>A mobile data communications system comprises a mobile device having a reconfigurable user identification module (eg Reconfigurable SIM â described as a â RIMâ ) operable to store a mobile identity, the mobile device being operable so as to provide mobile data communication via a mobile network selected from a set of available mobile networks, subject to the mobile identity being registered with the selected mobile network; and an account control server comprising: a memory to store identification and payment details for a user of the mobile device and a mobile identity provider to provide a mobile identity to the mobile device and to an authorisation server of a mobile network; the account control server being arranged so that, in response to a request by a user of the mobile device to obtain data access by a particular mobile network, the account control server provides a mobile identity to the mobile device for storage by the user identification module, provides the same mobile identity to the authorisation server of that mobile network, and provides the identification and payment details relating to that user to that mobile network. Particularly applicable to devices with machine to machine communications (M2M), eg satellite navigation devices or microwave ovens.</p> |
