Remote sim card replacement and activation process

A subscriber identifying module including a microcontroller in a mobile telecommunication network which is configured to communicate with at least one remote system in the network, said subscriber identifying module and said remote system being adapted to store at least one parameter identifying a user in the network, said subscriber identifying module comprising:

• a one-time account identifier designed for a one-time logon to the network,
• a permanent account identifier, said permanent account identifier being deactivated, characterised in that said one-time and permanent account identifier are prestored in said at least one remote system, and said microcontroller is programmed to:
• a) use the one-time account identifier to logon to the network when said subscriber identifying module is switched on;
• b) exchange the one-time account identifier with the permanent account identifier in the subscriber identifying module upon successful logon to the network as the active account identifier in the data processing device,
• c) upon successful logon to the network, send an activation request for deactivating in the remote system an account identifier attached to a second subscriber identifying module and activating the permanent account identifier attached to the first data processing device.

A remote telecommunication system in a mobile telecommunication network, said network system being able to communicate with a subscriber identifying module said network system storing:

• a one-time account identifier for a one-time logon of a subscriber identifying module to the network
• a permanent account identifier attached to an original data processing device,
• the network system storing a set of instructions for accepting logon of a replacement subscriber identifying module in the network and treating an activation request from the replacement subscriber identifying module by the following operations:
• deactivating the account identifier attached to the original subscriber identifying module and,
• activating the account identifier attached to the replacement data processing device.

A data processing device including a microcontroller and configured to communicate with at least one remote system distributed on a network, said data processing device and said remote system adapted to store a plurality of parameters identifying a user account belonging to a subscriber, said data processing device comprising:

• a one-time parameter comprising the active account attached to said device designed for a one-time use,
• a permanent parameter identifying an account attached to said data processing device, said permanent parameter being deactivated,
• wherein said one-time and permanent parameter are stored in said at least one remote system, and said microcontroller is programmed to:
• d) using the one-time parameter to logon to the network when said data processing device is switched on;
• e) exchanging the one-time parameter with the permanent parameter, upon successful logon to the network, said permanent parameter becoming the permanent active account,
• wherein said first device and said at least one remote system store a parameter identifying a current active account attached to a second data processing device to replace, and upon successful logon to the network, a program automatically stored in said first device sends an activation request for exchanging the plurality of parameters from the old for the new one in said at least one remote system, with the current active account being deactivated.
