Systems and methods are provided for enhancing cellular network coverage. In order to enhance network coverage, churn data is correlated with the measured coverage data for the multiple locations in the cellular network. Based on the correlation, a network readiness status in the multiple locations is determined. Network resources are then deployed to any of the multiple locations determined to have a network readiness status of not ready.
