If the user tries to do something that requires PIN2 (CHV2), the product will refuse the action with
a “+ CME ERROR: 17” (SIM PIN2 required). The product then waits for SIM PIN2 to be given.
Of course, if SIM PIN2 is blocked, SIM PUK2 is required instead of SIM PIN2.
For example, the product needs PIN2 to write in the fixed dialing phonebook (FDN), so if SIM
PIN2 authentication has not been performed during the current session, SIM PIN2 is required.

Please note that the product only requests PIN2 or PUK2 once. Therefore, if they are not entered
properly, the next + CPIN? command will return “+CPIN: READY”.
Defined values:
<pin> Personal Identification Number. 4-digit number.
<puk> Personal Unblocking Key needed to change the PIN. 8-digit number.
Enter PIN2: +CPIN2
Description: This specific command is used to validate the PIN2 code (CHV2), or to validate the
PUK2 code (UNBLOCK CHV2) and to define a new PIN Code. Of course, the +CPIN command
allows PIN2 or PUK2 codes to be validated, but only when the last command executed resulted in
PIN2 authentication failure.
PIN2 length is between 4 and 8 digits, PUK2 length is 8 digits only.
Command syntax: AT+CPIN2=<pin2>
Command Possible responses
AT+CPIN2=1234
