How Do I Use Key Guard Or Key Lock On My SGH-A257 (Magnet) Phone?
To lock the keypad press the Keypad Lock key (#12 below) then press the left soft key for Yes. To unlock press the left soft key for Unlock then press the OK key.
The handset also features four other lock features ( Auto Keypad Lock, Phone Lock, SIM Lock and Application Lock), all described below:
The Auto Keypad Lock automatically locks the keypad when it has been idle for a while.
In Phone Lock mode, you can answer calls, but the phone must be unlocked to place outgoing calls (except to emergency numbers). The phone locks automatically the next time it is powered on and stays locked until you enter the correct lock code.
Application Lock will restrict access to phone application menus, except the My Menu shorcuts. Once you have locked the applications, you must enter the correct lock code to access the associated menus.
Please contact your service provider for more information about any of these lock features. Service Provider Contact Information
