Halting the technological revolution  The tax creates disincentives when we consider the potential losses that will result in the technology sector. The technological revolution in Tanzania will be jeopardised. The growth of mobile phones across Tanzania indicates the emergence of a ‘network society [1] ’ but if the population stops buying mobile phones this will end. Taxing SIM cards may deter individuals from buying mobile devices, due to the additional cost. Further, alternatively if the manufacturers and providers attempt to take the burden of the tax to keep the price of a mobile down then supply will be affected. Currently individuals use multiple service providers to get cheaper phone call rates; however, this would no longer be a sensible option.  Taxing SIM cards will introduce costs to the entrepreneurship and service provision operating through mobiles. Technology holds great benefits within the twenty-first century; imposing taxation acts to exclude access and limit potential job opportunities. Mobiles have taken services to the people [2] - a vital resource for health services and information, aid distribution, banking, and commerce.  [1] See further readings: Castells, 2011.
