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.
