The service provider will in most cases unlock the phone for you. contact them first.

Okay, well i do not know much about these phones but i will give you a few options that work for verizon.
You can try the standard "0000" also there is the possibility of it being the last four digits of your cell phone number. and if that doesnt work you can call your service provider and they can reset the code.
