This volume fills a major gap in publications on migration and digital media worlds by bringing information and communication technology (ICT) to the fore of our understanding of migrants’ experiences in, and practices of, connectivity and mobility. During recent decades, migration within and from East Asia has become paradigmatic of the changing substance and patterns of global mobility. Focusing on migration within and beyond East Asia, a region defined by its global migration and its leading role in ICT use and development, this volume explores the pervasive use of smartphones as an everyday reality for East Asian migrants, advocating the necessity of understanding how they live their lives both online and offline. In this respect, the originality of this volume lies in its interdisciplinary analysis of migrants’ activities at the crossroads between physical and digital spaces. Our theoretical innovation and empirical findings will open an avenue to investigate the novel shape and scales of contemporary connectivity and mobility.
