Restore lost mode iphone 5c?

I bought an iphone 5c and they did not tell me it was in lost mode How do i restore it so i can use it? I think it is a lost or stolen iphone

You can't and it was probably stolen.

You can't you need your apple ID and password to reset the phone, ask the seller for it. If they don't give it to you then tell them to buy it back, or call the police because it's definitely stolen if they won't help you or say they don't know their login
