4.18.1 Examples: Enabling / disabling PIN 1 authentication
Example 1
To lock or unlock the SIM card: The "SC" parameter enables or disables the
SIM PIN authentication (PIN 1) when you power up the GSM engine:
AT+CLCK="SC",1,9999
Activates SIM card lock.
OK
As a result, SIM PIN 1 must be entered to en-
able ME to register to the GSM network.
AT+CLCK="SC",0,9999
Unlocks SIM card.
OK
When powered up, ME registers to the GSM
network without requesting SIM PIN1.
Note: Depending on the services offered by the
provider, this feature is not supported by all
SIM card types. If so, the command returns
ERROR when you attempt to unlock the card.
Example 2
To query the status of the SIM card lock:
AT+CLCK="SC",2
+clck: 1
SIM card is locked. SIM PIN1 must be entered
to enable ME to register to the GSM network.
