The growth has contributed to the economic-social growth and development of the country. In fact, Nigerian telecoms industry is presently referred to as the fastest growing industry in Africa. However, the growth does not come without the difficulties of inadequate quality of service and customer dissatisfaction with the mobile network services. These challenges has caused an increase in customer churn and attrition rate. Therefore, this study conducted a Critical review on previous studies to highlights the challenges facing the Nigerian telecoms industry. This study observed the main challenges facing the Nigerian telecoms industry are weak infrastructure, improper management of customer expectations, damages of network infrastructures and inadequate power supply. Based on the stated challenges, this study proposed the use of big data analytics that can be used by the MNOs to ensure adequate management of mobile network performance. The study envisaged that the use of big data analytics in Nigerian telecoms industry will enable the mobile network operators to understand the deterioration in the network traffic, kind of resources utilised, where the future traffic problems may occur and plan on how to efficiently reallocate infrastructural mobile network resources.enCustomer Satisfaction,Big data analytics,Telecoms industry,Quality of Service,mobile network operators,Mobile networkArticle
