How did the World change because of Cell Phones?

There are more people having access to a cell phone than a toilet. So "bad" it is.  But with the cell phones, earning and spending money is available in real-time everywhere in the world for any single person, from the North Pole to the South Pole and everywhere between.

According to the UK government:

"Over a billion people own a mobile phone but do not have a bank account. DFID [Department for International Development] support for the Consultative Group to Assist Poor technology programme alongside the Bill & Melinda Gates Foundation aims to use mobile phones and other technology to help 30 million people get better financial services.


As cell phones have become commonplace in the developing world, the field of "mHealth" (mobile health) emerged. mHealth programs connect remote communities with healthcare services and expertise, all conducted using cell phones.

Health workers in rural areas of sub-Saharan Africa use cell phones to contact medical specialists, who can help address critical health issues. That helps field workers determine what's treatable in the field, and identify patients who may need to be taken to a hospital.


According to the World Bank, three quarters of people on Earth have access to a mobile phone. There are now at least 6 billion mobile phone subscriptions active, up from 1 billion in the year 2000 -- and 5 billion of those are in developing countries. So a key way cell phones change the world is what they were designed for: communication.

Internet, the biggest online community and knowledge base

The Internet is the biggest collections of knowledge and communications in the history of humankind and the world, With the cell phones, it's possible to connect with anything and anyone.

Cell Phones Help Farmers and Their Communities

Studies demonstrated that access to cellular technology can have a dramatic effect on economic development in deprived areas. For instance, one study in the Journal of Economic Perspectives reported:

"The reduction in communication costs [as a result of the use of mobile phones] can increase the speed of information flows within the network, thereby allowing them to respond better to shocks [such as natural disasters, military conflicts, and epidemics]. Mobile phones also allow households to obtain information about potential shocks, allowing them to use such information to make planting and harvesting decisions, which can have important effects on yields (Rosenzweig and Binswanger, 1993)."

Long story short, the availability of cell phones to farmers helps them make more informed decisions about what to plant, when to harvest, and how much to sell crops for. These are all key factors for economic success in rural communities.

New business

New Marketplaces

CellBazaar is a bit like Craigslist for the developing world. Deployed in Bangladesh, it's a way to place or respond to ads about all sorts of products and services. And, like Craigslist, it's free. Originally deployed using SMS in 2006, it recently switched to using a web interface (which is also commonly available on modern smartphones). For instance, here's a web view of the current Air Conditioning items for sale on CellBazaar in Bangladesh. According to the company's CEO, Arild Klokkerhaug:

"[CellBazaar] launched as an SMS service back in 2006 and from this year we stopped it. SMS had a mission back then as few people had access to Internet. However, 160 characters are very limiting and not suitable for the quality ads that we strive to get. In the end it was not much used, especially when most people now can access internet also through regular mobile phones."

Find jobs

According to the World Bank, cell phones have helped people in Palestine find work. In a press release, they reported:

"In Palestine, Souktel's JobMatch service is helping young people find jobs. College graduates using the service reported a reduction in the time spent looking for employment from an average of twelve weeks to one week or less, and an increase in wages of up to 50 percent."

The service ran since 2006, and has reportedly helped thousands find work; its success stories explain why it matters so much.

I'm not sure this is good, but if you look anywhere where people gather, the majority is busy with their cell phone in their hands and staring at the screens.
