Mobile phones may be common and convenient but conversations may not be as confidential as we think. The best intelligence one can get is often through unguarded telephone conversations when someone believes that they are not being listened to, they will say things that they wouldn't otherwise.

Around the world there are more mobile phones than old fashioned landlines. The mobile phones of today are ultra-thin and ultra-light. Currently Motorola's best mobile is a little more than half an inch thick when you fold it shut and it weighs just over three ounces. It also includes a digital camera. Mobile phone manufacturers continue to compete to provide the most features in the most fashionable phone. The technology that Martin Cooper unveiled more than three decades ago has fundamentally changed lives around the world from grocery shoppers in Europe to farmers in Africa.

There are now over two billion mobile phones on the planet. There are more mobile phones in China than in any other single country in the world. China is the biggest mobile phone market in the world. There are more mobile phones in china than there are people in the United States.

Mobile phones had revolutionary impact on the way we communicate, mobile phones let people do what they have to do, when and where they want. This freedom relies on huge investments in high technology and the evolution of smaller and faster machines.

Each technology allows us to do a thousand times more. The mobile phone is helping people, goods and services to move and it is driving technology forward. Back in 1915 when the thermionic tube was invented, it powered the whole world war two and after that came the transistor. The transistor allowed us to do a thousand times more with less power and after that came the integrated circuit which was again thousand times smaller, requiring less and less power while providing more computing power. We are wearing more digital storage than was available on this planet, in the year we were born by a long way. This revolution is not going to stop any time soon.

We use mobile phones to talk through it, listen, we can send very minimal message. We don't need great technical knowledge in order to use it, We don't even need literacy to use it. It is almost universally accessible and this in itself is a very new thing for a piece of technology.

The technology starts off being very expensive. The first mobile phone was the size of a brick and cost a couple thousand pounds and phone calls were incredibly expensive. Now they come off priced at less than twenty bucks and the rate of phone calls have become lower.

A mobile phone nowadays is used as a text messenger, word processor, calendar, a clock, a diary, a dictionary, a compass, a scanner, a computer, an internet access, an email, a gaming console, a video camera, a television, a radio, a music sharing center, etc…

Ringtones were first invented via these devices itself. When mobile phone manufacturers first developed their devices, they had the opportunity to put music within them. That's how we got early tones coming from the manufacturer to start with which were a series of sound to let the owners know that their phone was ringing. Firstly there was the monophonic tune and then came the polyphonic tune. Nowadays we are in a position where we call it the true tone or real sound and that is in fact an actual clip of a real piece of music.


In India we now have more mobile phones than landlines. Even though landlines are cheaper and available, people still prefer mobile phones to landlines. Now in India, mobile phones are becoming accessible to the very poor. The sort of people who live in the eighty-six thousand villages all over the country that have no connectivity at all. Mobile phones can ease the lives of the poor. Let's take the case of a farming woman from a town in India. The woman is carrying a heavy load of vegetables which she actually harvested in her backyard. She does not know when the bus will come and if the bus comes and she gets into the bus with her heavy load of vegetables, she is not quite sure that the market at the next stop is still open. When she goes in the market if its open, she is not sure if that particular vegetable that day on that market is well priced enough to meet her ends. This is where communication plays a crucial role.

This woman could also go to the rural communication center also known as tele-centers. There she can find a man and a woman sitting there waiting to provide services. She goes into this place asks to know when the bus arrives and thanks to the telephone facility, this service provider person might call the nearest person to ask when the bus is coming and what is the rate of the particular vegetable in the market and is the market open or not?

We cannot go to every village raining tele-centers. Imposing a tele-center on a village does not always work. It only works if the demand comes from the villagers themselves and it meets their needs. A good way out would be not to have any tele-center but lots of cheap handsets distributed out to many more people.


The mobile phone has brought more telephony to the whole continent of Africa in the last 5 years than the landline telephone was able to bring since its inversion in the last hundred years. Mobile phones are highly appreciated in Africa, they are very important because it enables the people there, to reach everyone and everyone. It is saving money, life, transportation. The mobile phone in Africa is now as important as the bicycle once was. Everybody, from a shoe polisher to a guy in the market to the highest executive, depend on mobile phones rather than the landlines. The mobile phone can be considered to be a technology that gives people the power to make things better on their own. Africa is now part of the world where the subscriber count is growing the fastest. Mobile phones give us economic benefits. They save us the trouble of making wasted journeys, make it easier to find work; they allow you to call several markets if you are a farmer or a fisherman to find out the best price for your product. They also compensate for bad infrastructure i.e. places where we don't have good roads, postal services or fixed network. Mobile phones boost economic activities in a big way. The price of handsets has fallen greatly in the last eighteen months. We can now get mobile phones in less than thirty dollars. All of those things put in the hands of the poor, they can then benefit from these great things mobile phones can do.

The mobile phone is a force for good benefiting billions of people and changing the way we all behave. There is however a darker side to the mobile phone revolution. We don't know yet all the risks in health, in ecology, in security but it is known that mobile phones have been used to trigger bombs in Madrid, in London, in Israel, in Iraq and India. The mobile phone has become crucial to state security. Everyone's calls are now routinely scanned and monitored. While it can argued that the innocent have nothing to fear, this is not entirely true. Nowadays it is possible to track back a person if a call is being made. For example, let's say that there is an executive chief officer of a big company and he has commercial rivals who have got a new product, new service, new piece of software that is going to seriously do damage to the company's business. Then, arises the issue of whether it is possible for the company to listen to its commercial rivals' mobile phone calls. There is no legal way the company can do that but it is possible to do it, illegally.

Today more than two hundred million Americans have a mobile phone. For many of us mobile phones are essential and the younger we are the truer that is.

On the streets of London, new school ringtones and latest mobile phones are objects of desire.

Mobile phones have become agents of change and modifiers of behavior. They alter our notion of time and space. They blur the boundaries between private and public. Mobile phones expand the sense of self, making us seem grander and more important.

People like carrying their mobile phones around. They do not carry it in their pocket or hand bags but they are holding it in their hands and waving it around. We can see this in restaurants for example when people go to restaurants, even if their mobile phone is in their pocket, they take it out and place it on the table so that everyone can see it. Another example would be when there is a group of girls standing around and then there is a men flashing his mobile phone and talking continuously on the phone. The young girls think that he must be a busy man. The young girls were looking at him and suddenly his phone rang. People want to show off their phone so much that they are even pretend to be talk. Even if we do not need our mobile phone, we bring it out with us just to show off.

These days the mobile phone each person uses is considered to be an indicator of his/her status in society. It seems that to be part of the society especially among youths today, one has to be charged up, switched on and always connected. Nonetheless we have to be aware that non-stop networking can become addictive and intrusive. Most teenagers nowadays always have a mobile phone in there hand. It is like they are someone important and anybody can phone the him/her any moment. Some are in the middle of a text message while talking to someone else; giving an impression they have a really interesting life and so many friends. It is not uncommon in these modern days to meet young people who are talking to each other and texting at the same time. People even sleep with their mobile phones switched on.
