In this article, we explore the day-to-day importance of digital media, specifically the use of mobile phones in the lives of migrant minors—also known as unaccompanied foreign minors—in juvenile residential centres. For this study, we employed a general ethnographic methodology and, in particular, a workshop based on different artistic techniques that encouraged the young people involved to become active participants, committed from the start in the generation of the material to be used for the analysis of their daily practices. This approach emerged from the recognition of the importance for these young people to feel included and connected. Migrant adolescents take refuge in their mobile devices to participate in the youth microculture, both locally and globally. In addition, they are able to access different social networks that allow them to play out the personas they wish to adopt. Finally, we recognise the importance of digital media in allowing them to maintain close and affective relationships with their relatives, fellow citizens, and communities in their country of origin.
