This study investigated the performances of four operators of mobile telecommunications services in voice communications in Lagos and Oyo States in South Western Nigeria for the first five years of operation. Using the International Telecommunications Union (ITU) standard of measuring customer experience of voice telephony service through the voice quality scores known as the Mean Opinion Score (MOS), the study identified the quality of service in voice call between the year 2001 and 2006.
