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SIM PIN1 authentication is no longer valid.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".
