Once the modem and terminal emulator are ready enter the

following command:

AT+CPIN? <Enter>

The command requests that the modem respond as to whether a

password is required. The expected modem response is:

+CPIN: SIM PIN

The response confirms that the SIM Card PIN1 code is required

to unlock the Card. If you get a different response, contact the

SIM Card provider to determine if a different code is required. If

you get a response of “+CPIN: SIM PIN2” this may mean that

the Card is already unlocked or requires a different code.

The next step is to enter the PIN code for the SIM Card.

AT+CPIN=”1111” <Enter>

The modem should response with an “OK” which means the

PIN code has been accepted. This explanation assumes that the

default code of “1111” is being used. If you get an “ERROR”

reply, be sure that the command was entered as shown. If you

continue to get an error response, contact the SIM Card provider

to determine if a different code is required.

The next step is to enter the command to deactivate the PIN

code requirement. If your PIN code is different from the “1111”

then use this in the command in its place.

AT+CLCK=”SC”,0,”1111” <Enter>

The modem should respond with an “OK” which means the

command has been accepted. If you get an “ERROR” reply, be

sure that the command was entered as shown. If you continue to

get an error response, contact the SIM Card provider for further

information.

The final step should be to test that the SIM Card is unlocked

and will remain unlocked. Start by powering down the modem

and then reapplying power. Allow the modem to warm up for

about 30 seconds. The test consists of attempting to dial the 12-

digit data number for the other SIM Card in the terminal

emulator.

ATDT00<12-DIGIT DATA #> <Enter>

If you are able to dial the number without getting a prompt for a

PIN code then the code requirement is deactivated. The modem

should respond with “NO ANSWER” after several seconds. This

assumes the other modem is not communicating.
