A broad trend in the information and communication technology (ICT) industry is the customers’ expectation that services will continue to improve in terms of service/technology qualities (i.e., faster, easier to use, and more advanced service features). To meet these challenging demands, many ICT companies seek to provide new service/technology to customers based on innovations developed through research and development. Unfortunately, the customers’ willingness to adopt new technologies is not always a given, even if new technologies offer high quality improvements. Given the investments that carriers have had to make to roll out new generation mobile services and technologies, it is prudent to consider how experiences with initial mobile Internet service/technology relate to adoption/retention intentions as well as other factors that affect a consumer’s new technology adoption decision. Therefore, the purposes of this study are i) to develop a theoretical model for the mobile Internet technology adoption decision, ii) to test the proposed model empirically, and finally iii) to provide some insights for the mobile Internet service/technology provider community from a mobile user’s perspective.
