Abstract
In a telecommunications system including a plurality of different networks, terminals and smart cards, each terminal is usable in a particular network in association with one of the smart cards when that smart card is registered with that network. Each smart card carries secret information specific to its registered home network and with which the network can authenticate the smart card and allow use of the terminal with which that smart card is associated. Each smart card may be registered with one of the networks as its home network, selectively de-registered from its home network, and re-registered with a different one of the networks as its home network by obtaining data including an International Mobile Subscriber Identifier for use with that network. The Identifier is transmitted to the smart card, and the secret information relating to a particular network activated when registering or re-registering the smart card with that network.
