Why would ou think you are allowed to unlock an 5S, you have to be a paying customer using the handset for at least 6 months. Seeing as the 5S hasn't even been out 6 months your not going to get this unlocked through EE.
They have policies for reasons they won't bend them for you.
They won't even consider unlocking it.
