if its a 4S, it will work without any SIM in there. this is really a strange situation. I will have to ask you to check that your phone is really from sprint, cuz if you did a DFU restore then all settings are default. It could be a Verizon one.

Don't even put a SIM sprint in there. They're only needed for ROAMING outside the USA, and you need a nano SIM for iPhone 5/5C/5S for LTE service. After wiping without the SIM inside, go to settings, general, about and make sure the menu says, "Sprint 16.1," or, "Sprint," for the carrier.

If that sim is a sprint card and the phone does into activation then %100 it's not a sprint phone.
