In Kabul, Afghanistan, a young widow, Sukhirya Hassani, earns her living by renting out cell phones. For ten cents a minute, an Afghani customer can call a friend or relative living miles away. The widow is employed by Roshan, Afghanistan's mobile phone network, which has more than 1.2 million customers, who no longer have to walk to the next town to connect with friends, relatives, or business

Question

associates. In India, around 7 million people per month sign up for cell phone service. In 2010, the government calculated that India had approximate 500 million users with more to come. No wonder. For years, Indians in rural areas struggled to stay in touch with friends and family because land-line telephones were so hard to get. Often the wait for one was measured in years. Cell phones, however, have changed all that. Even those living in small villages can find a way to maintain contact with the people important to them. Cell phones have had a similar effect in Africa, bringing together people who once struggled to stay in touch because they had no land line, and the post office was miles away.
