This paper investigates the quality of service of GSM networks in Nigeria using the call drop rate and the call handover success rate as the key performance indicators. In the analysis, we have utilized the Erlang B probability formula, which highlights the service quality at any given moment on the number of channels available at that time. The parameters of the four main GSM services in Nigeria were analyzed with the help of data obtained from the Nigerian Communications Commission. The results show that the operators are not performing well with regard to these metrics; therefore, ways to increase not just the performance of the metrics but also the performance of the whole network are suggested. The analysis shows that GSM services in Nigeria are currently unreliable. Cell splitting, sectoring, and efficient resource management are highlighted as the possible means of maximizing the networks' quality of service when implemented. This implementation would lead to soft handover in the network; thus, creating a more robust telecommunication system.
