The price of ICT services constitutes a determining factor for ICT uptake and, as such, continues to be a focus of attention for regulators and policy-makers. Affordability remains the main barrier to Internet access at home in many developing countries. In Brazil, for instance, 44 per cent of all households with a computer did not have Internet in 2013 because they considered it too expensive or beyond their means (CETIC.BR, 2013). In developed countries, although not having Internet at home may be more attributable to other factors, such as lack of interest, cost still represents a barrier for many people. In the European Union, around one in five households without Internet cite cost as the reason, and seven out of ten of those who have Internet state that price is the most important factor when choosing the service (European Commission, 2013; European Commission, 2014). The importance of affordability also applies to other ICT services, and its impact goes beyond access, also influencing usage: over half of EU citizens limit their national mobile phone calls because of concerns about cost (European Commission, 2014).
