The adoption patterns for new technology such as mobile services are essential to understand for developing them further. Hence, it is important to study how willing people are to try new mobile services and do "facilitating" conditions have an effect on the consumers? adoption readiness. This study analyses how the mobile devices and the initial trial time used effect the initial mobile service usage experience and how this experience affects the likelihood of continuous usage. We will argue that the duration of the trial does not effect consumers? perceptions about mobile services when first trying them out, but familiarization of the device used has an impact on experience. We will go through the theoretical aspects of adoption of new technologies and specific aspects of the mobile business and present results from the field trial conducted last summer. The theoretical and practical implications are presented at the end of this paper.
