You can master reset it get the master reset code from service provider....

this is master code.. it has to be entered when your phone is started and asks for code..(security or master)..
if you type 5 times wrongly,the phone will get whole locked.. so,try 1 time and let me know about this..
if you fully typed 5 times wrongly ,you have to get a lead and software tools to unlock and that costs greater than the phone you got..
so,try 1 time and let me know..my email id:[email protected]
