*# codes sent with ATD cannot be used to enter the Master Phone Code.

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.

Example 1

Be sure that PIN 1 authentication is valid:
AT+CPIN?

+CPIN: SIM PIN

OK

AT+CPIN=9999

OK
