how the cellphone affects our community.
the cellphone affects our communities in a good and bad way. the cellphone makes it easier to talk to people from far distances in the quickest way possible. It's bad because people are always on their cellphones and they don't really pay attention to what they are doing.
how laws affect cell phones
laws affect the use of cell phones in a major way. you can't text and drive! it is illegal to talk on the phone while driving through a school or highway construction zone.
how money is involved with cellphones
money is involved with cellphones because there's a monthly fee you have to pay the carrier to be able to call and send text messages. there's also fees for some apps that you have to pay.
how cellphones affect our families
the cellphone affects my family because we can reach other family members easier and faster. for some of us that have family in another country, its a great way to stay in touch.
