I bought an iphone 5 with sprint (which is reseted) and it says i need a SIM card

I'm going to sprint store today but not sure if i should, what if its stolen. I don't know what to do

Have to have SIM card to complete activation. Just go buy one from them. They're cheap. Couple of bucks. Do you have Sprint? They don't care if it is stolen. They don't do drama or third party issues or mediate that kind of stuff. They sell new phones and plans. If it is then it's shut off and you won't be able to activate it anyway. It'll be blacklisted. They will want to sell you service though. Check and see. Best luck.
