This Kyocera Gratina 4G KYF31 smartphone has never been used; it is in perfect condition. My service provider was not able to help me use it in my area of New Jersey, USA. It's a nice sized phone; it fits comfortably in the hand. It has a low SAR (USA) rating for the head (0.783 W/kg) and body (0.798 W/kg) for radiation exposure. Japanese manufacturer.
