Method for deactivating and possibly reactivating SIM cards
First Claim
1. A method of deactivating i) a SIM card (i) and ii) a subscription of the SIM card using an on-demand-activation application (2 , comprising of steps of:
- using a computer (3) and an associated on-demand- activation (ODA) database (4), deactivating the subscription of the SIM card and the SIM card (i) by;
i) connecting the SIM card to the on-demand-activation (ODA) database (4);
ii) transferring an instruction to deactivate the SIM card and to cancel the subscription of the SIM card to the on-demand-activation application (2);
iii) transferring information in a memory of the SIM card, including card definition files comprising the International Mobile Subscriber Identity (IMSI) of the SIM card, to the on-demand-activation application (2);
iv) arranging the on-demand-activation application (2) to be connected to the network, the network including a Home Location Register/Authentication Center (HLR/AUC);
v) with the on-demand-activation application, retrieving the subscription information from the Home Location Register/Authentication Center;
vi) with the on-demand-activation application, replacing the International Mobile Subscriber Identity (IMSI) of the SIM card with a temporary International Mobile Subscriber Identity (IMSI-T);
vii) with the on-demand-activation application, a) storing said temporary International Mobile Subscriber Identity (IMSI-T) in the memory of the SIM card, and b) storing said temporary International Mobile Subscriber Identity (IMSI-T) in said on-demand-activation database (4); and
viii) with the on-demand-activation application, transferring to the network, including the Home Location Register/Authentication Center (HLR/AUC) (5), an instruction to cancel the subscription of the SIM card in the network including in Home Location Register/Authentication Center (HLR/AUC);
wherein the method provides that the SIM card (i) is reactivated using i) the retrieved subscription information and the temporary International Mobile Subscriber Identity (IMSI- T) stored in the on-demand-activation database (4), together with ii) the temporary International Mobile Subscriber Identity (IMSI- T) stored on the SIM card.

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.
