This section details the commands that are available when a SIM card is present. These commands are 
available only in RUIM software versions.  
Note that the PIN codes used in this section are for example purposes only and do not reflect the actual PIN 
codes programmed into the modem. Contact your service provider to obtain the actual PIN codes used by 
your modem.  
Enter PIN  +CPIN  
Description:   This command is used to enter the ME (Mobile Equipment) passwords (CHV1 / CHV2 / 
PUK1 / PUK2, etc.), that are required before any ME functionality can be used. CHV1/CHV2 
must be 4 to 8 digits long, PUK1/PUK2 must be 8 digits long. The application is responsible 
for checking the PIN after each reset or power on if the PIN was enabled.  
 
Syntax:  
 
Command syntax: AT+CPIN=<pin>  
Command  
Possible Responses  
AT+CPIN=1234  
OK  
Note: PIN code is correct  
 
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:  
 
    Command 
syntax: 
AT+CPIN=<Puk>,<NewPin>  
Command  
Possible Responses  
AT+CPIN=00000000,1234  
Note: Enter PUK and new PIN  
+CME ERROR: 16  
Note: Incorrect PUK  
AT+CPIN=12345678,1234  
Note: Enter PUK and new PIN, 2nd attempt  
OK  
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: UIM PIN  
 
CHV1 is required  
+CPIN: UIM PUK    
PUK1 is required  
+CPIN: UIM PIN2    
CHV2 is required  
+CPIN: UIM PUK2    
PUK2 is required  
+CPIN: PH-UIM PIN  
UIM lock (phone-to-UIM) is required  
 
+CPIN: PH-NET PIN  
Network personalization is required  
 
+CME ERROR: <err> 
SIM failure (13) absent (10) etc.  
 
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.
