The role played by the use of technologies in improving business processes is vital. Taking SMEs, for example, mobile phone technology is used to perform multiple activities, especially in developing countries that are characterized by low ICT readiness. The effective uptake of any technology requires maximum acceptance amongst individuals. While various factors have been studied on how they relate and influence intentions and actual usage of mobile phones amongst employees of SMEs, there is a lack of research that focuses on the social influence in that context. This is a quantitative study performed using SEM involving 459 respondents. The study extends TAM with a subjective norm before testing a resulting theoretical model. The results show that subjective norm has a significant influence on both the perceived usefulness and behaviour intention. This paper also provides recommendations to the key stakeholders on the approaches to utilization of mobile phone technology in SMEs.
