Other relevant finding is that our results do not provide empirical support for sector knowledge as exerting a significant influence on customer retention. The reason may be that the vast majority of mobile users are familiar to some extent to the services provided by companies. Maybe the probable reason lies in that the cost of learning and getting informed about companies and services provided is low. Other possible reason may be that the services offered by mobile companies are quite similar; so learning and getting informed about sector characteristics does not lead to significantly better offers.
Additionally, our research conceptual model identifies customer satisfaction as a strong determinant of customer intention to switch mobile services’ provider. This finding implies that mobile providers should better in the long term increase customer satisfaction in an attempt to minimize customers’ defection, considering that customer satisfaction is one important goal for mobile service companies in achieving economic success (Deng et al., 2010). This finding is line with Eshghi et al. (2007) who confirmed that satisfied customers tend to be loyal.
