There is limited research studying mobile phone adoption by actual consumers in the Arab countries, although the region had an incredible growth in mobile usage between the years 2000 and 2014. The main aim of this paper is to develop a conceptual framework that can explain mobile adoption by customers in the Arab countries. An extensive analysis of the existing literature related to technology adoption in general as well as mobile adoption in the Arab countries was conducted. Accordingly, this paper proposes a new conceptual model based on some modifications of the Unified Theory of Acceptance and Use of Technology (UTAUT2) and adding new variables which were also found related to the studied phenomenon. This research provides several important implications for researchers willing to study mobile adoption in the Arab countries as well as telecommunication companies operating or willing to operate in the region. Consequently, this model is set forward based on future empirical validation of it in Arab countries.
