    What carrier are you on? Where did you obtain the phone meaning is it unlocked and what kind of SIM is in it? You would more than likely need to contact the Carrier you are on to find out if you have a valid SIM and it can be used or you might need to purchase or be given a new SIM card to use in the phone. We need more info to help you but your carrier is your best start.
