This study is about the influence between usages of smartphone by studying the characteristics of killer-app on smartphone in a perspective of switching cost and lock-in and studied about influence between killer-app and continued usage of mobile telecommunication companies. As a result of the study, information characteristics and network externality has a positive effect on switching cost and lock-in. Switching cost has a positive influence on lock-in but not on intention of continued usage of killer-app. It has shown that lock-in has a positive influence on intention of continued usage of killer-app and plays a mediating role between switching cost and continued usage of killer-app. Finally, intention of continued usage of killer-app has a positive influence on intention of continued usage of mobile telecommunication companies.
