EXAMPLE 3

This example shows that after successful SIM PIN1 authentication the counter of the AT^SPIC execute and read command refers to SIM PIN2, i.e. it does not reflect the status of SIM PIN1. This may be a problem if the user enters a wrong PIN1 and is not aware that the number of attempts left to enter SIM PIN1 is counted down.

+CREG: 0 at+cpin=1234

OK +CREG: 2

+CREG: 1	The mobile ist properly registered to the network.
at+cpin?
+CPIN: READY	The AT+CPIN? read command confirms that SIM
	PIN1 authentication was successful.
at^spic
^SPIC: 3	As SIM PIN1 authentication was successful, the
	counter relates to SIM PIN2 and correctly indicates
	that the user has 3 attempts to enter SIM PIN2.
OK
AT^SPIC?	Likewise, the read command notifies that the ME is
	waiting for SIM PIN2.
^SPIC: SIM PIN2
OK
at+clck="SC",0,456789	First attempt to enter a wrong SIM PIN1.
CME ERROR: incorrect password
at^spic
^SPIC: 3	SIM PIN1 authentication is still valid, and the counter
	relates to SIM PIN2.
at+clck="SC",0,456789	Second attempt to enter a wrong SIM PIN1.
CME ERROR: incorrect password
at^spic
^SPIC: 3	SIM PIN1 authentication is still valid, and the counter
	relates to SIM PIN2.
at+clck="SC",0,456789	Third attempt to enter a wrong SIM PIN1.
CME ERROR: incorrect password
+CREG: 0	SIM PIN1 authentication is no longer valid.
at^spic
^SPIC: 10	This time, after the SIM PIN1 code has been dis-
	abled, the counter indicates the status of SIM PIN1
	and notifies that 10 attempts are left to enter the SIM
	PUK.

To avoid conflicts we recommend to use the AT^SPIC read and write commands rather than the execute com- mand only. The read command clearly states the currently required password, and the write command may be used to get the counter for a specific <facility>, in this case for example "P2".
