Mobile phone is increasingly widespread among University students, while different factors can affect students' behavior towards the use and acceptance of mobile technology. One of the methods to measure these factors is the Unified Theory of Acceptance and Use of Technology (UTAUT). The purpose of this study was to evaluate the Behavioral Intention of University students for acceptance and use of mobile phone in their studies. The study employed the extended UTAUT2 model (Venkatesh et al. 2012) which was adapted to the Greek context. The participants were 540 students of different Universities across Greece, who completed an online questionnaire. The most important predictors for students' Behavioral Intention to use mobile phones in their studies were Habit (the strongest one), Performance Expectancy and Hedonic Motivation. The most important predictor for actual mobile phone use was Behavioral Intention. Gender, age and experience did not have any moderating effect. The findings of this study enhance the evidence on mobile phone acceptance among University students, and have implications for students' training.
