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

Note: Enter PUK2 and new PIN2

+CME ERROR: 16

Note: Incorrect PUK2

AT+CPIN2=12345678,1234

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”

Note: Select Phonebook FDN

AT+CPBW=5,”12345678”,145”test1”

Note: Write entry 5 in the FDN

+CME ERROR: 17

Note: PIN2 not yet entered

AT+CPIN2=1234

Note: Enter PIN2

Note: PIN2 successfully entered

AT+CPBW=5,”12345678”,145”test1”

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

Note: Get the number of attempts left

+CPINC: 2,3,10,10

Note: First CHV1 attempt was a failure

AT+CPINC?

Note: Get the number of attempts left

+CPINC: 2,3,10,10

Note: First CHV1 attempt was a failure
