Despite the growing importance of mobile social commerce (Ms-commerce), little research has been conducted on the effects of informational-related factors on Ms-commerce and the role of trust in user willingness to share their experiences. Drawing on the Information Adoption Model, we examine the effect of information usefulness, quality, credibility, and need on information adoption and the effect of information adoption on trust and willingness to share Ms-commerce experience. Using data from 280 UK Ms-commerce users, we applied Partial- Least-Squares Structural Equation Modelling (PLS-SEM) to test the model. The findings show that informational-related factors have a significant and positive impact on Ms-commerce information adoption. Moreover, the effect of information adoption on trust and willingness to share Ms-commerce experiences was found to be significant. More importantly, this study has also yielded support for the mediating role of trust on the relationship between information adoption and willingness to share Ms-commerce experiences.
