The main goal of this research is investigate and analyse the Quality of Service (QoS) of cellular mobile networks in Nigeria using some Network Key Performance Indicators (KPI). This study is limited to Visafone Mobile Network which is licensed to provide fixed wireless access telecommunications services on State by State basis in Nigeria under the license category classified as Private Network Links (PNL).Visafone mobile Network runs on Code Division Multiple Access (CDMA) technology. In this study the following KPIs: Call Setup Success Ratio (CSSR), Call Drop Ratio (CDR) and Traffic Channel (TCH) Congestion Ratio measurements were sampled and collated from the Network Operating Centres (NOCs) and their values were evaluated against the standard threshold values set by telecommunications regulatory body, the Nigerian Communications Commission (NCC) in Nigeria; the results obtained showed that busy hour TCH Congestion Ratio was 0.0062 which is lower than the NCC stipulated value of ≤ 2%. Also the busy hour CDR was 0.7129 and again below the NCC threshold of ≤ 2%. Finally the Busy hour CSSR was 98.7267 which is within the expected threshold set by NCC.
