Telecommunications is becoming critical infrastructure for Nigeria’s economy as growing digital activity increases dependence on network connectivity for payments, commerce, financial services, remote work, enterprise operations and other economic activities.
The sector contributed 9.19 per cent to Nigeria’s real Gross Domestic Product (GDP) in the first quarter of 2026, according to data from the National Bureau of Statistics, reflecting its growing weight in an economy increasingly driven by digital transactions and connectivity.
But the economic value of telecommunications extends beyond its direct contribution to GDP.
Financial analyst and chartered accountant, Oluwatosin Olaseinde, said capital deployed into telecommunications infrastructure was creating productive capacity for businesses and individuals across the wider economy.
He said the infrastructure enables software developers and remote professionals to serve international clients, businesses to transact through digital platforms, and educators and service providers to reach customers beyond their immediate locations.
The scale of investment required to sustain the infrastructure is substantial.
Financial planner, Kalu Aja, said MTN Nigeria alone had committed more than N1.62 trillion in cumulative infrastructure investment across the country, covering network infrastructure, fibre deployment, spectrum and power requirements.
The investment comes as businesses increasingly depend on reliable connectivity to operate, transact with customers and access digital services.
Nigeria’s financial services ecosystem illustrates the growing dependence.
The expansion of digital banking, fintech platforms, electronic payments and agency banking has been supported by telecommunications networks connecting customers, merchants, financial institutions and payment platforms.
The country’s electronic payment ecosystem processes transactions worth hundreds of trillions of naira, with telecommunications infrastructure providing the connectivity required for data transmission between users, financial institutions and payment platforms.
The growth of Point-of-Sale transactions has similarly expanded the role of network connectivity in everyday commerce, creating income opportunities for agents and extending financial services into communities where conventional bank branches are limited.
Small businesses are also increasingly using social media, messaging platforms, digital payments and online marketplaces to reach customers and conduct transactions without the physical infrastructure previously required to operate at scale.
However, the growing dependence on telecom infrastructure is exposing the economy to the consequences of network disruptions.
The Nigerian Communications Commission recorded more than 5,000 fibre cuts in the first six months of 2026, incidents that can interrupt digital payments, business operations, public services and other connectivity-dependent activities.
Israel Ihaza, founder and chief executive officer of PropTech company Oikus, said the problem reflected gaps in coordination around underground infrastructure, particularly during road construction and excavation.
For businesses, a connectivity disruption can mean loss of access to customers and payment channels, while remote workers and digital service providers can experience interruptions to their operations.
The vulnerability of fibre infrastructure therefore extends beyond the telecommunications industry, particularly as more commercial and financial activities depend on digital connectivity.
At the same time, operators face rising costs of maintaining and expanding their networks.
The industry continues to contend with multiple taxes and levies, right-of-way costs, foreign-exchange pressures and the high cost of powering network infrastructure.
These pressures have become more significant as operators seek to expand capacity in response to rising demand for data.
Chief Executive Officer of MTN Nigeria, Karl Toriola, has warned that the economics of continued investment must support sustainable returns, while Chairman of the Association of Licensed Telecommunications Operators of Nigeria, Gbenga Adebayo, has similarly raised concerns about the impact of rising operating costs on network expansion and service quality.
The Federal Government’s designation of telecommunications infrastructure as part of Critical National Information Infrastructure provides a framework for greater protection of network assets.
Implementation, however, will depend on coordination between federal agencies, state governments, local authorities, road contractors and communities, particularly around construction activities and fibre routes.
As more businesses move transactions online and financial and commercial activity becomes increasingly dependent on digital platforms, the sustainability of telecom infrastructure is becoming a broader economic concern.
The issue is no longer simply how many Nigerians have access to telecommunications services, but whether the networks supporting the country’s growing digital economy can remain reliable, affordable and sufficiently investment-ready to sustain economic activity.
