iPhone 13. It is on the AT&T network. We upgraded this phone to the iPhone 15. It has been wiped and is at the factory reset. It has both a physical slot for a SIM and an eSIM. This phone has been totally encased since day one. No scratches on the front or back. Everything works as it should. Camera and screen were protected with tempered glass protection since day 1 and are perfect. Battery health is around 75%
