METHOD FOR DEACTIVATING AND POSSIBLY REACTIVATING SIM CARDS
First Claim
1. Method of deactivating and possibly reactivating a SIM card (1) and a subscription using an ODA (2) (On Demand Activation) application, comprising a computer (3) and an associated ODA database (4), for deactivating and reactivating the subscription and SIM card in a mobile network, characterised in that, when deactivating a subscription and SIM card (1) the SIM card is connected to the ODA database (4), in that an instruction to deactivate the SIM card and to cancel the subscription is transferred to the ODA (2), in that information in the memory of the SIM card, such as the card definition files comprising the IMSI (International Mobile Subscriber Identity) of the SIM card, are transferred to the ODA (2), in that the ODA (2) is arranged to be connected to the network, including a HLR/AUC (5), in that the ODA retrieves the subscription information, in that the ODA (2) replaces the IMSI of the SIM card with a temporary IMSI called IMSI-T, in that the ODA stores said information in the memory of the SIM card together with the IMSI-T in said database (4), in that the ODA (2) also stores said information together with the IMSI-T and in that the ODA transfers to the network, including the HLR/AUC (5), an instruction to cancel the subscription in the network including HLR/AUC (5) and in that the SIM card (1) may be reactivated using and the information stored in the ODA database (4) and on the SIM card including said IMSI-T.

Abstract
When deactivating a subscription and SIM card, the SIM card is connected to the ODA database, an instruction to deactivate the SIM card and cancel the subscription is transferred to the ODA, information in the memory of the SIM card including the IMSI (International Mobile Subscriber Identity) of the SIM card, is transferred to the ODA, which is arranged to be connected to the network, including a HLR/AUC. The ODA retrieves the subscription information, and replaces the IMSI of the SIM card with a temporary IMSI called IMSI-T. The ODA stores the information in the memory of the SIM card together with the IMSI-T in the database. The ODA also stores the information together with the IMSI-T and transfers to the network an instruction to cancel the subscription in the network. The SIM card may be reactivated using the information stored in the ODA database and on the SIM card including the IMSI-T.
