When accessing the internet, smartphones allow users to access social media, search for information, and communicate with others while on the go. Smartphones no longer only provide a way to connect; this technology also allows people relate to others and maintain their relationships. This study explores (a) student smartphone use behaviors, (b) student perceptions of peer interactions, (c) student perceptions of faculty interactions, (d) how these factors relate to students' perceptions of social integration at a university, and (e) any differences related to gender and age. The correlational research in this study revealed statistically significant findings between smartphone use and student perceptions of social integration amongst peer groups. Results of t-tests identified differences between males and females, while the ANOVA identified differences across birth cohorts. Additionally, the qualitative interview data presented as the emerging themes of connection, convenience, and technology culture related to smartphone use and perceptions of social integration. The results of this explanatory mixed methods study support a direct link between technology use and interaction, regardless of gender or age. However, no such link can be found between technology use and integration. Instead, college students' technology use appears to flow through interaction, resulting in integration.
