OnCell G2150I AT Command Set Security Commands

Enter PIN: +CPIN

Description: This command is used to enter the ME passwords (CHV1 / CHV2 / PUK1 / PUK2, etc.), that are required before any ME functionality can be used. CHV1/CHV2 is between 4 and 8 digits long, PUK1/PUK2 is only 8 digits long.

If the user application tries to make an outgoing call before the SIM PIN code (CHV1) has been confirmed, then the product will refuse the “ATD” command with a “+CME ERROR: 11” (SIM PIN required).

The application is responsible for checking the PIN after each reset or power on if the PIN was enabled.

Command syntax: AT+CPIN=<pin>

Command	Possible responses
AT+CPIN=1234	OK
Note: Enter PIN	Note: PIN code is correct
AT+CPIN=5678	+CME ERROR: 3
Note: Enter PIN	Note: Operation not allowed, PIN previously entered

After 3 unsuccessful attempts to enter the PIN (Personal Identification Number), the PUK (Personal Unblocking Key) will be required. PUK validation forces the user to enter a new PIN code as a second parameter and this will be the new PIN code if PUK validation succeeds. CHV1 is then enabled if PUK1 is correct. The application therefore uses this command:

AT+CPIN=<Puk>,<NewPin>

Command	Possible responses
AT+CPIN=00000000,1234	+CME ERROR: 16
Note: Enter PUK and new PIN	Note: Incorrect PUK
AT+CPIN=12345678,1234	OK
Note: Enter PUK and new PIN, 2nd attempt	Note: PUK correct, new PIN stored

To ascertain which code must be entered (or not), the following query command can be used: AT+CPIN?

The possible responses are:

+CPIN: READY	ME is not pending for any password
+CPIN: SIM PIN	CHV1 is required
+CPIN: SIM PUK	PUK1 is required
+CPIN: SIM PIN2	CHV2 is required
+CPIN: SIM PUK2	PUK2 is required
+CPIN: PH-SIM PIN	SIM lock (phone-to-SIM) is required
+CPIN: PH-NET PIN	Network personalization is required
+CME ERROR: <err>	SIM failure (13) absent (10) etc

Please note that in this case the mobile equipment does not end its response with the OK string. The response +CME ERROR: 13 (SIM failure) is returned after 10 unsuccessful PUK attempts. The SIM card is then out of order and must be replaced by a new one.

Example: 3 failed PIN validations + 1 successful PUK validation
