This paper aims to analyze the phenomenon of device divide in the Brazilian context in order to understand how different Internet access devices and sociodemographic factors influence the development of digital skills. The research uses the microdata of 2014 and 2016 editions of a Brazilian nationwide survey named ICT Households survey. The main findings show that mobile devices are widely used by Brazilian Internet users. However, while in upper classes this device plays the role of complementary access to other devices, allowing users to access the Internet using computer and mobile platforms, for lower-income groups mobile is the only means of Internet access, substituting the use of computer equipment. The results also demonstrate that Internet users who access the Internet using both computational and mobile devices exhibit the highest level of digital skills. In contrast, users connecting exclusively via mobile show lower levels of digital skills which might reduce their effectiveness in using the Internet. These outcomes show the relevance of understanding the conditions of Internet access as well as their implication for the development of digital skills and provision of Internet services.
