More than two decades after the Dot Com crash, the mobile industry in developed markets continues to suffer from structurally weak returns, despite rising data demand and ongoing investment. This paper examines how mobile telecoms has evolved from a high-growth, high-return sector into a capital-intensive utility that has consistently failed to earn its cost of capital.

Using long-term evidence from the UK and other mature markets, the analysis shows how flat revenues, declining real ARPUs, rising capital intensity and repeated spectrum investments have combined to depress returns on capital employed. While operators continue to deliver more capacity, higher speeds and wider coverage, much of the economic value created has accrued to consumers and digital service providers rather than network operators themselves.

The paper argues that current regulatory and competition frameworks are misaligned with the economic realities of a utility-like mobile sector. Without changes that allow operators to reduce capital intensity, earn higher returns, or access new revenue sources, the industry risks ongoing underinvestment and financial decline. It concludes that governments and regulators must fundamentally rethink their approach if the mobile industry is to remain sustainable and capable of supporting future digital growth.
