Abstract
The ODA database (4) contains SIM card (1) information related to the cards that shall be activated. When a SIM card (1) is inserted into a mobile equipment, such as a mobile telephone, and the mobile equipment is switched on, the ODA (2) is connected to the SIM card for updating the SIM card with a card definition file. The ODA (2) is arranged to be connected to a HLR/AUC (5) in order to transfer information stored on the updated SIM card, and the HLR/AUC is arranged to set up a subscription for the SIM card.
