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.
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".

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

SIM PIN1 authentication is still valid, and the counter
relates to SIM PIN2.

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.
