The togetherness of smartphones and social media has emerged two negative phenomena called Nomophobia and FoMO. Nomophobia, the fear of no mobile phone, and FoMO, the fear of missing out developments on social media, present a risk especially for university students. University students now have longer durations of social media and smartphone usage due to Nomophobia and FoMO. With this increase in usage, university students are more likely to be predisposed to Nomophobia and FoMO, and therefore, have problems leading to fear, anxiety and stress. This study aimed to identify pre-service teachers’ metaphorical perceptions of smartphone, Nomophobia and FoMO. In the literature, studies on Nomophobia and FoMO have been conducted as quantitative research. This study was designed with mixed method which includes at least one quantitative and one qualitative method. The findings of the study differed by smartphone usage duration of the pre-service teachers and their scores of the Nomophobia Questionnaire and the FoMO scale. According to the findings, the participants frequently used the metaphors of “friend, organ, eating, need, lover” for smartphone, “being lonely, nothingness” for Nomophobia and “failing to be up to date, necessity” for FoMO.
