The document discusses the importance of risk management for cellular network providers and mobile virtual network operators (MVNOs). It notes that as the traditional cellular market becomes saturated, MVNOs allow network providers to segment their business and minimize idle capacity. However, the separation of network and service providers under the MVNO model requires more robust risk management plans for each business segment. Effective risk management practices, including integrated plans and risk reduction strategies, are critical for network providers to satisfy MVNO partners and survive in the evolving cellular industry.
