Multi-Tech Systems CDMA Wireless Modem Enter PIN2 +CPIN2, PIN Remaining Attempt Number +CPINC

Chapter 7 - SIM Card Operational Commands

Enter PIN2 +CPIN2

Description: This command is used to validate the PIN2 code (CHV2), or to validate the PUK2 code (UNBLOCK CHV2) and to define a new PIN2 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. The PUK2 length must be 8 digits.

Syntax: Command syntax: AT+CPIN2=<pin2>

Command	Possible Responses
AT+CPIN2=1234	OK
	Note: PIN2 code is correct

After 3 unsuccessful attempts, PUK2 will then be required. PUK2 validation forces the user to enter a new PIN2 code as a second parameter and this will be the new PIN2 code if PUK1 validation succeeds. The application therefore uses this command:

Command syntax: AT+CPIN2=<puk2>,<NewPin2>

Command	Possible Responses
AT+CPIN2=00000000,1234	+CME ERROR: 16
Note: Enter PUK2 and new PIN2	Note: Incorrect PUK2
AT+CPIN2=12345678,1234	OK
Note: Enter PUK2 and new PIN2, 2nd attempt	Note: PUK2 correct, new PIN2 stored

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

The possible responses are:

+CPIN: READY	ME is not pending for any password
+CPIN: UIM PIN2	CHV2 is required
+CPIN: UIM PUK2	PUK2 is required
+CME ERROR: <err>	SIM failure (13) absent (10) etc.

The product requires that the PIN2 code be successfully entered in order to write a entry into the Fix Dialing Phonebook (FDN).

Command	Possible Responses
AT+CPBS=”FD”		OK
Note: Select Phonebook FDN
AT+CPBW=5,”12345678”,145”test1”		+CME ERROR: 17
Note: Write entry 5 in the FDN		Note: PIN2 not yet entered
AT+CPIN2=1234		OK
Note: Enter PIN2		Note: PIN2 successfully entered
AT+CPBW=5,”12345678”,145”test1”		OK
Note: Write entry 5 in the FDN		Note: Command now successful

PIN Remaining Attempt Number +CPINC

Description: This command is used to get the number of valid attempts for PIN1 (CHV1), PIN2 (CHV2), PUK1 (UNBLOCK CHV1) and PUK2 (UNBLOCK CHV2) identifiers.

Values:	<n1>, <n2> are the attempts left for PIN1, PIN2 (0 = blocked, 3 max)
	<k1>, <k2> are the attempts left for PUK1, PUK2 (0 = blocked, 10 max)
	For this to work, the card should be present at the time of initialization. Otherwise, an error
	will be sent (+CME ERROR: 10).
Syntax:	Command syntax: AT+CPINC
	Response syntax: +CPINC: <n1>,<n2>,<k1>,<k2>
	Command	Possible Responses
	AT+CPINC	+CPINC: 2,3,10,10
	Note: Get the number of attempts left	OK
		Note: First CHV1 attempt was a failure
	AT+CPINC?	+CPINC: 2,3,10,10
	Note: Get the number of attempts left	OK
		Note: First CHV1 attempt was a failure
