  • Remote SIM card replacement and activation process
    Patent number: 8095132
    Abstract: A data processing device including a microcontroller and configured to communicate with at least one remote system distributed on a network. The data processing device and the remote system are adapted to store a plurality of parameters identifying a user account belonging to a subscriber. The data processing device comprises a one-time parameter comprising the active account attached to the device designed for a one-time use, and a permanent parameter identifying an account attached to the data processing device, the permanent parameter being deactivated. The one-time and permanent parameter are stored in the at least one remote system, and the microcontroller is programmed to: use the one-time parameter to logon to the network when the data processing device is switched on; and exchanges the one-time parameter with the permanent parameter, upon successful logon to the network, the permanent parameter becoming the permanent active account.
