Purpose – The objective of this research is investigating how trust and performance expectations affect a decision to embrace a mobile commerce solution in Sri Lanka's burgeoning travel and tourist industry. Methodology - The research employed a quantitative and logical approach, assessing a theoretical model with assumptions, to identify the link between study variables. The samples were gathered in Sri Lanka. A self-administered questionnaire that was dispersed to a select number of people using Google Forms was employed in data gathering. On a five-point Likert scale, 468 respondents from the final sample shared their thoughts on the variables influencing the adoption and use of mobile commerce. For data analysis, structured equation modeling was used. Result – The results of this study showed that the two factors "Performance Expectancy" and "Trust" significantly influenced the researcher's adoption of M-commerce. Study Implications - Business owners, particularly those looking to build a company around mobile commerce applications, policymakers looking to encourage the growth of mobile commerce, marketeers, academic researchers interested in adoption science and business development, and generally any organization involved in the travel and tourism sector will all benefit by the research
