Multi-Tech Systems, Inc. GPRS AT Commands Reference Guide (Document Number S000293J)
Description:
Values:
Syntax:
This command enters 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.
<pin> is the Personal Identification Number. A four-digit number.
<puk> is the Personal Unblocking Key needed to change the PIN. An eight-digit number.
AT+CPIN=<pin>
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>
To determine which code must be entered (or not), the following query command can be used:
AT+CPIN? The possible responses are:
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.
