Changemaking with Mobile Phones Group is aimed at anyone interested in the impact of mobile technology in the developing world, and how non-profit organizations can make best use of this technology in their social-change work. Mobile phones have revolutionized 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, they have opened up huge economic opportunities for their users. People can now be more easily contacted when work becomes available, use them to advertise their services, receive market prices, health reminders, 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. Join our group and see what other innovations are happening right now.
