First this belongs in Q and A section. Second, Sprint doesnt even use Sim cards, I have Sprint Moto X and the only reason there is a sim card in there is for the phone to stop telling you "NO SIM" its basically a place holder. and the only way they will give you one if activate or buy a phone from them
