The aim of this research is to explain how various cell phone services, features and applications may increase individuals’ degree of cell phone dependence and even lead to cell phone addiction. So far there has been paucity of studies looking into cell phone dependence/addiction from the perspective of adoption and continuation of use of different cell phone services and applications. This study proposes an integrated model for cell phone dependence based on Technology Acceptance Model (TAM), Unified Theory of Acceptance and Use of Technology (UTAUT), Diffusion of Innovations theory (DOI), Mobile Phone Technology Adoption Model (MOPTAM) and theory of optimal flow
