Mobile commerce is becoming increasingly important in business. Wireless application protocol (WAP) is one of the most widespread technical standards for mobile commerce. Following continuous technical evolution, WAP has now included various new features. However, WAP services continue to struggle for market share. Hence, understanding the adoption of WAP services is increasingly important for enterprises interested in developing mobile commerce. This study aims to: (i) identify the critical factors of WAP services adoption; (ii) explore the relative importance of each factor between WAP adopters and non-adopters; and (iii) examine the causal relationships among variables on WAP services adoption behavior. This study reports empirical test of the adoption of WAP services in Taiwan, based on the theory of planned behavior and innovation diffusion theory. The results indicate that the critical factors influencing the adoption of WAP services include connection speed, service costs, user satisfaction, personal innovativeness, ease of use, peer influence, and facilitating conditions. Some suggestions for subsequent researchers and practitioners seeking to understand WAP services adoption behavior are also provided.
