OKAY I had that exact same phone so this is what I know: 1)SIM card required, any plan prepaid or contract that uses a SIM card will do. 2)There is a MicroSD card slot on the left hand side. 3)This phone can really take a beating. I dropped that exact same model phone in water twice, and tomato soup once. I dropped it more times than I can count. It's broken now after it fell off my lap and hit the ground from about a foot. So, be CAREFUL about dropping it. My phone lasted about two years, and I'm sixteen.
