Introduction: The African migrants that arrived in Sweden between 2005 and 2010 experienced a lack of regular contact with relatives and friends back home because of different factors due to the tools of communication during that period. Later, the migrants experienced a transition in tools of communication that allowed transnational communication with African countries, using ICTs tools of communication such as Whatsapp, Facebook, and others. Purpose:This thesis is focused on the digital transition in ICTs and aims to provide a better understanding of digital communication and it's impact on the African diaspora in Sweden. The research analyzes a specific timeline between the 2005-2010 period, which is split in three successive stages by the author ( Pre-transition, The transition and Post-transition). The ultimate goal is to provide a contribution to the existing theoretical knowledge with empirical evidence, thereby replenishing the Comdev academic field of studies. Methodology:To explore these questions, the empirical data was collected through semi-structured interviews with members of the African diaspora in Sweden Conclusion and contribution:The results show that the participants could not afford to buy on a regular basis the prepaid cards that were very expensive and ineffective. Emails were used by a few, also the internet was very expensive back home. The African's diaspora relationships with the homeland suffered negative consequences due to a feeling of abandonment felt by the relatives back home. The transition in communication occured after a few years, leading to a process defined as gradual, the learning of the new tools of ICTs and the cost of the smartphones played a role in the transition period. The following post-transition period allowed an interconnectedness on a global level and improved tremendously the relationships with relatives. Results also show that constant communication is becoming overwhelming on many levels and social aspects. The research revealed that ongoing processes during the transition process of digitalization are a broad field for investigation.
