If the SIM card is blocked, the PIN code (that is, the PIN) is requested when the
module is started. To enable the SIM card lock, the PIN is requested. A maximum of
three attempts to enter the PIN is allowed. The AT+CLCK="SC",<mode>,<PIN>
command can be used to block or unblock the SIM card. When <mode>=1, the SIM
card will be blocked. When <mode>=0, the SIM card will be unblocked. Before
enabling the SIM card lock, it is recommended that the AT+CPIN? command be used
to check the current state of the SIM card lock. If "+CPIN: SIM PUK" is returned, the
correct PUK must be entered to change the SIM card settings.
