Multi-Tech Systems, Inc. GPRS AT Commands Reference Guide (Document Number S000293J)
Example:
Three failed PIN validations + one successful PUK validation
If the user tries to do something which 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”.
