5．In the early 1980s to have a mobile phone was an impossible luxury to most people in the world．People did not usually assume that they had to reach someone via a mobile phone on a regular basis．It didn't matter if you didn't have a mobile phone．In the modern society owning a mobile phone has no longer been a privilege，but a necessity．Almost anyone needs a mobile phone to reach as well as be reached by others no matter where they are．The days are gone when phone ownership depended on a fixed address and a high salary．
It is amazing to see how fast and how far the mobile phone has spread．Teenagers have become the channel through which mobile phones have found their way into the wider society．The young were also the first to see the potential of text messaging．However，the mobile phone is by no means a mere technological innovation； it heightens a basic human quality-the ability to communicate-there are few aspects of life that it fails to touch．
The mobile phone is mobile only because the user is mobile．We are in a time of mobility．Never before have so many people been on the move，whether as commuters，workers，travelers，freelancers or migrants．Mobile phones encourage and respond to this mobility．They help those far away from their home to keep in touch with their families．They serve as a means of people fitting into a new social environment．
The mobile phone changes the way people organize their lives．Plans can be made or changed at any moment and while organizing in advance used to be extremely important to any social gathering，now only the vaguest plans are necessary．Mobile phones even change the experience of being alone as they provide countless way to pass the time．
It is ridiculous to compare a mobile to a body part，but carried on the person，often all the time，they are something to which people have grown attached．
