•Use the read commands "AT+CPIN?" and "AT+CPIN2?" to check which password is currently required.

If the responses to "AT+CPIN?" and "AT+CPIN2?" both read "READY", there is no currently required pass- word, and the referrer of the execute command "AT^SPIC" is explicitly undefined.

In these cases, the read command "AT^SPIC?" may be used to determine, which password the response of the execute command actually refers to. Also, the write command may be used in order to retrieve the counter for a specific password.

•For passwords associated to the phone lock (''PS'' lock set by client or factory) or other factory set locks, such as ''PF'', ''PN'', ''PU'', ''PP'', ''PC'' the number of attempts is subject to a timing algorithm explained in AT+CPIN. If these passwords are incorrectly entered the counter first returns 3, 2 and 1 remaining attempt(s), but then gives the total number of attempts which amounts to 63 (see example below).

•See also Chapters AT+CLCK, AT+CPIN, AT+CPIN2, AT+CPWD, AT^SLCK for further information on locks and passwords.

Examples

EXAMPLE 1

The client fails to provide a correct SIM PIN three times The counter decreases each time. After the counter reaches zero, the SIM PUK is required. After failure to enter a correct SIM PUK, the counter decreases.
