Mobile phones are revolutionising communications across the globe, more so in developing countries where landline infrastructure is lacking in many rural (and some urban) areas. Mobile phones represent the only means of communication for hundreds of millions of people.

At the same time, mobiles have opened up huge economic opportunities for their owners. They can now be more easily contacted when work is available, they can use them to advertise their services, receive market prices, job information, and so on. Others now make a living ‘sharing’ their phones and charging non-owners to make calls. Some make a living charging phone batteries, selling top-up vouchers, or covers and chargers.
