In a smartcard having a subscriber identity module ("SIMI") that cooperates with a mobile station to effect communication with a telecommunications network, a system for, and method of, disabling the smartcard. The system includes: (1) data commnications circuitry that transmits a code uniquely identifying the smartcard from logic circuitry within the smartcard to the telecommunications network via the mobile station, the code employable by the telecommunications network to search a disable database associated therewith, the telecommunications network returning a disable command if the code is found in the disable database and (2) disabling circuitry that incapacitates the logic circuitry to prevent an operation thereof, the smartcard being incapacitated with respect to the telecommunications network and systems independent of the telecommunications network.
