See also section 11.6 for the 9555/9522B extensions to this command.
Exec Command: +CLCK=<fac>,<mode>,<passwd>
Execute command is used to activate or deactivate the SIM card PIN Code, or to enable or disable the
Phone Lock feature in the ISU. The current SIM card PIN Code or Phone Unlock Code is required to
perform these actions.
Note: This command will not work unless the SIM PIN has been entered using the +CPIN command.
Note: Once this command has been issued to disable the PIN, neither it nor the +CPIN need to be issued again
unless the PIN function is reactivated.
The following parameter values are currently supported:
<fac>:
“CS” CNTRL Surface (Enable/Disable Phone Lock feature)
“SC” SIM (Activate/Deactivate SIM card PIN Code)
<mode>:
0 Disable (Deactivate)
1 Enable (Activate)
<passwd>: string type, enclosed by “ “; for example, “1234”.
Note: Factory default SIM card PIN Code is “1111”
Note: Factory default Phone Unlock Code is “1234”
Test Command: +CLCK=?
Test command returns the facility values supported by the phone. The response is in the form:
+CLCK: (list of supported <fac>s)
Note: Only “CS” will appear as a supported value if there is no SIM card in the device.
Note: +CLCK is closely related to +CPIN and +CPWD. See these commands for additional information.
