Mobile phones are now used ubiquitously in everyday life around the world. However, using mobile devices for learning activities (i.e. m-learning) is not as popular as initially expected. This study explores the factors that affect m-learning apps acceptance among mobile phone users and investigates how personality, readiness, and motivation contribute to m-learning acceptance. The results of partial least squares analysis (PLS) with 297 valid samples indicate that conscientiousness and m-learning readiness are critical antecedents of intrinsic motivation and extrinsic motivation, with both motivations affecting intention to use m-learning app systems significantly and positively. Finally, theoretical and managerial implications are presented based on this study's interesting findings.
