Malawi is one of the poorest nations in Africa. Unemployment rates are high. And those who have jobs have meager salaries.(5)Yet a recent report by the International Telecommunications Union, ITU, says on average, Malawians use more than twelve dollars a month on cell phones. This is more than half of what an ordinary Malawian earns. In neighboring Mozambique, consumers spend just over a quarter of their income on mobile phone usage. But in Kenya and South Africa, the figure is significantly lower amounting to less than five percent of average monthly earnings.
     (6)This lack of competition is why mobile tariffs are so high. The government might be forced to intervene to bring down the cost of using a mobile phone.
    But it is not just the cost of mobile services that is an issue in Malawi.(7)Many consumers also want the providers to give them value for their money by improving the quality of service they get. There are times that the network is very bad. Even the Internet is very slow.
