Mobile phone theft has been one of the common crimes on the street. With this Symbian application, you are adding some security to your mobile phones. The security are as follows: Auto-Lock (the phone is locked after a period of time and you have to input a password to unlock the phone), Theft Alert (the application sends a SMS to a specified number when a different sim card is input into your mobile phone), Audio Alert(the application plays a loud sound when input an incorrect password), Enable incoming call (this feature allows the phone to receive a phone call after the phone is locked), Enable keylock (this feature allows the end user to use the keypad after the phone is locked)
