mobile phones are defantly a necessity, we need them to contact friend and family, arrange plans for work or school, and incase of emergancy. they are very important and we can now access movies, videos, music and the internet on mobile phones.whats dissapointing is that some schools try to ban their students from having mobiles, what if on the way home your child is in an accident, how can they phone home? or if another situation hapopens where they need to make a phone call and a pay phone isnt near by.we rely on mobile phones alot but some people do buy just to show off, in my opinion they are just for contact purposes.
