To store the SIM CHV1 code for verification, use the gsm sim authenticate slot command in controller 
configuration mode.

gsm sim authenticate 0,7 pin slot 0–1

Controller configuration (config-controller)

This command works only when the SIM is locked. If you enter it incorrectly several times, the SIM is 
blocked. To avoid this, when CHV1 verification fails, you must re-enter the CHV1 code to initiate 
verification.

The following example shows how to authenticate using an unencrypted PIN:

router(config-controller)# gsm sim authenticate 0 1234 slot 0

Authentication type:

0—Specifies an unencrypted (cleartext) PIN that follows this parameter.

7—Specifies a hidden PIN that follows this parameter.

A 4 to 8 character code provided by your carrier to lock or unlock the SIM 
card.
