This essay examines the absence of mobile phone technology from the narrative of No Friend but the Mountains in order to reflect on the centrality of mobile digital technology for the intellectual work the book undertakes. Examining a key scene from No Friend but the Mountains where telecommunications technology is represented as a limited resource within Manus Prison, it draws on media theory and life writing theory to argue that the affordances of mobile digital technologies enabled the emergence of a new, collaborative form of life writing that both affirms the value of an individual life, while also making powerful claims regarding the collective suffering and dehumanization at the heart of Australia’s mandatory detention policy.
