A method for checking a temporarily disabled subscriber identity module (SIM) card disposed in mobile equipment (ME), comprising: (a) storing a code verification state of the SIM card in the ME, the code verification state being selectively a “verification of PIN/PUK code required” state or a “verification of PIN/PUK code not required” state; (b) executing a SIM card start-up procedure when the SIM card is temporarily disabled; and (c) determining whether verification of PIN/PUK code is required for the ME, evaluating the stored code verification state, determining whether verification is required, determining the SIM card has been removed or damaged, when verification of PIN/PUK code is not required and the stored code verification state is “verification of PIN/PUK code required” or when verification of PIN/PUK code is required and the stored code verification state is “verification of PIN/PUK code not required.”
