Online migrants – as a symbiosis between homo mobilis and homo numericus – embody social transformations which are the result of unprecedented interconnectedness within mobile, cosmopolitanized social worlds. This chapter argues that information and communication technologies (ICTs) have transformed migrants’ experiences in contrasting ways. They facilitate the co-presence of mobile actors in multiple locations, enable new forms of intergenerational solidarity within transnational families, and foster new networked forms of mobilization and cohesion at a distance. In this way, ICTs enhance new mechanisms of digital agency in migration contexts.
