At my high school, you can use a phone during break, lunch, passing periods, before, and after school. If you get caught during class, most teachers will give you a warning, then take it away if you continue to use it. They usually give it back at the end of class or after school.
My parents rule was that we could get a phone when we start junior high school (7th grade). That applied for me and my older sister, but of course my younger sister got hers in 5th grade I think. :rant: :nuts: I mostly just use mine to call my dad, my mom never answers hers. EVER. I use it to call or text my friends to make plans too, I never really just text people just to talk.
