answered question 3/23/2010 Is There A Samsung C3050 Phone Lock Default Password? On Security Settings The Top Option Says Phone Lock, Apparently I've Got A Password But I Know I Haven't, Only Found Out About It Today. If There's No Default Password Can Anyone Help Me Reset It? Most phones are set to either 6 zero's or 4 zero's for the phone unlock code , but if the phone was purchased from another individual they may have changed it ,,,,,try it and see
