You can call your carrier and ask them to help you or go to google and search for how to hard reset your phone. This will set it back to factory default. This will reset everything and probably whatever is on the SIM card.

go to your service store and they will give you a default code

Did I just respond to this question??? Someone here just posted a very similar question on a Samsung device.

Normally I would expect the default value to be the last 4 digits of your telephone number. If you changed it, good luck.

Please try entering the last 4 digits.

If this doesn't work, if you changed the code, you will probably have to get help from the service provider or your manufacturer. http://www.samsung.com/us/consumer/mobile/mobile-phones/index.idx?pagetype=type
