The advent of the technology called Global System of Mobile Communication (GSM) has brought in a paradigm shift from the conventional English Language Writing, to what researchers now call SMS system of communication. This has been observed in many places as well as Nigeria. English language being an official language in Nigeria and fast becoming a global language cannot diffuse into un-intelligibility through such influences like SMS language. The importance of language generally to man is such that any virus that portends catastrophe to it attracts special attention. Some research works have been carried out to trace the influence of the emerging trends on the users of this technology; this project is one of researchers aims at identifying the influence of SMS language on the writing performance of secondary school students, in Nsukka Urban Area of Enugu State, Nigeria. An extensive literature review has been carried out on the GSM technology, its special features especially the Short Message Services (SMS) that brought in this encoding of English language through text message, computer mediated communication, the importance and dynamics of language and other relevant aspects of the project topic. From the foregoing it is obvious that the SMS of GSM influences students ’ writing.
