Mobile learning suggests and supports the new concepts of learning such as ubiquitous-, augmented-, personalized-, online-, mixed reality-, context-sensitive-, informal-, and ambient learning and teaching. This paper aims to introduce Mobile Assisted Language Learning (MALL) and its potentials in language learning and teaching. MALL is a merging language teaching methodology which can effectively integrate listening, reading and speaking activities. It can also develop academic study, critical thinking and research skills. MALL is ideal for language learners who travel or commute very often and for those who want to have fun by learning English. Mobile phone is superior to a computer in portability – a very much valued feature by most young English language learners. Professionally developed materials can be delivered through mobile phones to improve English language learners’ vocabulary acquisition and critical thinking skills. Students can read the definitions of words, sentences, improve pronunciation skills, and develop their thinking skills through quizzes. Useful MALL software as well as references are readily available and updatable online. This review paper will explore the theoretical foundations and applications of mobile learning in the literature and discuss the feasibility of employing this ubiquitous technology in language learning in Iranian EFL context.
