I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If it's not active with a carrier anymore it's doubtful they will give you the unlock code. Your best bet is to use a place online like the link below. You pay them X dollars, provide IMEI and they give you unlock code which as Tiras25 said, is unique to each device. Once you obtain the code, go to:

Options > advanced options > SIM card
type in MEPD
then type MEP2
enter unlock code
power off device then turn back on
