You can unlock it by flashing your mobile if your mobile is a CDMA mobile...

It has an video explanation.

If your mobile is not an CDMA mobile , you can get the network unlock code(NUC) by just contacting the current network provider customer caredepartment.It is free of cost.

Therestrictioncodecan be got from your old service provider..This restriction code iskeptto prevent someone who stole themobile from using it withanotherprovider...

They will have a security check done with your date of birth etc..to verify whether you are the exact owner of the phone..
