Of course if SIM PIN2 is blocked, SIM PUK2 is required instead of SIM PIN2.

For instance, the GSM module needs PIN2 to write in the fixed dialling phonebook

(FDN), so if SIM PIN2 authentification has not been done during the current cession the

SIM PIN2 is required:

Application to GSM AT+CPBS=”FD” Choose FDN

GSM to application OK

Application to GSM AT+CPBW=5,”01290917”,129,”Jacky” Write in FDN at

location 5

GSM to application +CME ERROR:17 SIM PIN2 is

required

Application to GSM AT+CPIN?

GSM to application SIM PIN2 SIM PIN2 is

required

Application to GSM AT+CPIN=5678 Enter SIM PIN2

GSM to application OK

Application to GSM AT+CPBW=5,”01290917”,129,”Jacky” Write in FDN at

location 5

GSM to application OK Now writing in

FDN is allowed

Please note that the GSM module ask only once PIN2 or PUK2, so if they aren’t entered

right, the next +CPIN? command will return ”+CPIN: READY”.

Remark

In the way Application to GSM, an ”h” character shall be added before the PIN value if

cyphering mode (with D.E.S algorithm) is on. See +EXPKEY command.

Same remark for +CLCK and +CPWD commands.
