Mobile phone services’ adoption and acceptance issues may have a significant impact on business and personal communication practices at the regional and global levels. An extended technology acceptance model (TAM)is tested in the U.S. and Turkey. Explored are key factors that influence usefulness, ease of use, and intentions to use, such as mobile Internet access, E-Mail, and payments. The results provide support for TAM from both samples and for the importance of variables such as efficacy and personal innovativeness. Differences between the two samples are observed and culture-based implications are made.
