This is a 16gb iPhone 6s Space Gray.I recently upgraded to the iPhone X and no longer need this phone. It works perfectly and is unlocked. It is a A1633 model that is both CDMA & GSM compatible. It doesn’t have a scratch on it. I had a glass screen protector on it (still on it)and in a case since day one. It includes the charger, all documentation and unused and unopened headphones. $160 shipped.
