This paper presents a method to transfer voice message through SMS in GSM network with and without using compression technique and then their results are compared. Generally, SMS is not used to transfer voice because it doesn’t have high bandwidth data service like GPRS, EDGE, and HSDPA. In this paper two approaches are used to transfer voice through SMS. Firstly, voice message is transferred without using compression technique, Secondly; Prediction by Partial Matching (PPM) technique is used to compress payload text of SMS. Major functionality of the algorithm is to convert voice message in to characters, than apply compression method on those characters. Finally, set those compressed characters as a payload text of SMS, and transmit it over GSM Network. For testing the proposed method an application is developed using J2ME language. We test our application on Nokia N95 with different voice messages up to 360 times.
