Mobile phones are now a greater part of student’s life therefore, teachers must make the most of this tool to create opportunities for learning and developing skills. This research used mobile phones and listening and speaking skills in EFL students to help them produce paraphrased versions of lectures they heard fostering critical thinking abilities. This study was developed in B1 students enrolled at the 6th level of English at Linguistics Competence Department at Universidad Nacional de Chimborazo UNACH with a sample of 50 students. The project implementation took ten sessions and students learned the techniques to effectively paraphrase and the pitfalls they should avoid when applying this strategy. The analysis of T-student test yielded that the experimental group outperformed the control group. The main results showed that mobile phones help students boost not only their listening and speaking skills, but also their critical thinking ability.
