Adoption behaviour differences for mobile data services: m-internet vs. m-portals

Abstract

This study attempts to investigate the potential differences among individual adoption patterns between mobile portal and mobile internet services usage. A theoretical model that reflects six unique predominant factors of IS usage is developed and is empirically tested using data collected from mobile data services MDSs users 116 mobile internet users and 178 mobile portal users. The results indicate that there are differences among the adoption behaviour of mobile portal users and mobile internet users. Specifically, mobile internet use is likely to be driven by utilitarian expectations and the perceived usefulness of accessing the web through this alternative medium. Conversely, mobile portals use is likely to be dependent on the users' personal innovativeness and is not significantly affected by the utility of the mobile service itself. Moreover, we find indirect effects of performance expectancy, facilitating conditions and social influence to the behavioural intention to use mobile internet.
