This case study attempts to elucidate the effects of mobile phones as tools for teaching reading in fostering motivation in EFL students. Through qualitative research techniques, the researcher analyses the impact that the implementation of a set of activities in a reading techniques course has on second-year English language learners' motivation. Focus groups and questionnaires help gather the students' perceptions of their involvement, enjoyment, and investment; the atmosphere created during the implementation of the activities, and their overall experience. In conclusion, the ubiquity of cell phones provides advantages in the development of motivation towards learning English and in fostering independence.
