This paper explores the possibilities of using mobile technology in the teaching and learning of the English language. A sample of 50 Sandwich students/teachers of the English language was drawn through a multi-stage sampling technique. The instrument used to collect data for this study is a ten-item questionnaire on integrating mobile phones in the teaching and learning of English. This instrument was validated by two language experts in the Department of English and Literary Studies, University of Nigeria, Nsukka. Data collected for this study were analysed using the percentage system represented in line charts. The results showed that mobile phones are instrumental in teaching and learning of English in classrooms. The paper concludes that M-learning promotes cooperative and collaborative learning through the enhancement of learner's use of authentic English language that would make it possible for them to construct their own knowledge. Based on the results of this research, the researchers recommend that mobile phone can be integrated in teaching and learning of English as a Second Language
