Enter Pin/Puk Code +Cpin - Wavecom WMO1-G900 User Manual

Wavecom GSM Modem

4.9. Enter PIN/PUK code +CPIN

This command is used to validate the PIN code, or to validate the PUK
code (and define a new PIN code).
If the user application try to establish an outgoing call before having
validated the SIM PIN code, then the GSM module will refuse the "ATD"
command with a "+CME ERROR: 11" (SIM PIN required).
It's up to the application to validate the PIN after each reset or power on.
The application shall therefore use the command :
Application to GSM
GSM to application
Application to GSM
GSM to application
After 3 unsuccessful codes, the PUK will then be required. The PUK
validation forces the user to enter as a second parameter a new PIN code
which will be the future PIN code if the PUK validation succeeds. The
application shall therefore use the command :
Application to GSM
GSM to application
Application to GSM
GSM to application
To know which code has to be entered (or not), the following
interrogation command will be implemented :
The possible responses are :
+CPIN: READY
+CPIN: SIM PIN
+CPIN: SIM PUK
+CME ERROR: <err>
Please note that in this case the mobile does not finish its response with
the OK string.
