Identity module with interchangeable unique identifiers

A telecommunications system comprising:

• a plurality of different wireless telecommunications networks;
• a smart card that (1) is registrable on each of the plurality of different wireless telecommunications networks and (2) includes multiple unique identifiers, each of the multiple unique identifiers being associated with a respective one of the plurality of different wireless telecommunications networks, wherein the multiple unique identifiers are included in a priority list that orders the multiple unique identifiers into a predetermined sequence that is based on determined priorities of the multiple unique identifiers;
• a service platform that communicates with the plurality of different wireless telecommunications networks;
• and
• a mobile device, operative in accordance with the smart card, to communicate with each of the plurality of different wireless telecommunications networks when the smart card is registered on that network,
• wherein the smart card comprises a common security key associated with at least two of the multiple unique identifiers such that the smart card is registrable with each one of the plurality of different wireless telecommunications networks when a corresponding unique identifier and the common security key are authenticated for a selected wireless telecommunications network that is selected for current registration,
• wherein the smart card is associated with an encryption algorithm that is used to generate the common security key which is associated with the at least two of the multiple unique identifiers such that the at least two of the multiple unique identifiers are linked to the encryption algorithm,
• wherein the smart card attempts to connect to one of the plurality of wireless telecommunications networks by interchangeably selecting for use one or more of the multiple unique identifiers in accordance with the predetermined sequence, the interchangeably selecting for use ending at least when a connection is established,
• wherein the service platform is operative to instruct the smart card to reorder the predetermined sequence of the multiple unique identifiers, wherein the smart card is operative to reorder the predetermined sequence of the multiple unique identifiers upon instruction,
• wherein the reordered sequence of the multiple unique identifiers is at least partially dependent on a predicted device functionality for the mobile device, the predicted device functionality being determined for each of the plurality of different wireless telecommunications networks,
• wherein the smart card is configured such that, when a particular unique identifier, which is included among the multiple unique identifiers, is deleted from the priority list, the particular unique identifier (i) is no longer interchangeably selectable for use to connect the smart card to any wireless telecommunications network included in the plurality of wireless telecommunications networks and (ii) remains stored on the smart card even after being deleted from the priority list, and
• wherein the particular unique identifier, after being deleted from the priority list, is subsequently either (i) purged from the smart card or (ii) placed back into the priority list such that the particular unique identifier again becomes interchangeably selectable for use to connect the smart card to at least one wireless telecommunications network included in the plurality of wireless telecommunications networks.
