Motorola G24 ユーザーズマニュアル

This command locks the SIM card, and therefore is only relevant for phones that use SIM cards. 
It unlocks the SIM card when the proper SIM PIN is provided and unblocks the SIM card when 
the proper SIM PUK is provided.

The SIM card is unlocked only once the provided pin is verified as the SIM PIN. If the required 
PIN (determined by the error code returned from the requested operation or the Read command) 
is SIM PUK or SIM PUK2, the second pin is required. This second pin, <newpin>, is used to 
replace the old pin in the SIM card. When entering the pin, a <new pin> is not required.

For a list of commands that can be given when the G24 is awaiting the SIM PIN or SIM 
PUK, refer to

The SIM card lock is another level of security independent of the phone lock (See

 presents a diagram of what occurs when using the SIM card. Note that if an incorrect 

password is entered three times, the G24 requires that a master password be entered, If this also 
fails three times, the SIM will be blocked, and you will have to go to your provider to unblock it.

A SIM card related error is returned if an AT command operation is unsuccessful due to a SIM 
card problem. The following table shows the SIM card errors.
