Nigeria’s telecommunications market is entering a new phase of competition where network capacity, rather than subscriber numbers, has become the determining factor for success. Airtel Nigeria, the country’s second-largest operator, has been building aggressively to challenge MTN Nigeria’s long-standing dominance, adding 1,561 sites over three years to bring its total to nearly 17,200 by December 2025. The operator has also committed $500 million to strengthen its network infrastructure, focusing on expanding in cities and corridors where networks are most strained.
Dinesh Balsingh, CEO of Airtel Nigeria, said in a statement that two years ago the operator was operating roughly a 15,000-site network, but has since crossed the 17,000-site count and will continue to invest in building more capacity. The shift comes as internet demand in the market surges, with consumption reaching 1.26 million terabytes in February 2026, pushing existing networks closer to their operational limits. For operators, the priority is no longer expansion for growth alone, but preventing congestion in a market where millions rely on mobile data for payments, work, and everyday communication.
Demand is rising faster than infrastructure can be deployed, leaving operators in a constant catch-up cycle. Data from the Nigerian Communications Commission shows 145,141 base stations as of December 2024, which against a population exceeding 240 million reveals a persistent infrastructure gap of roughly 60 base stations per 100,000 people. Airtel’s reported 46,918 base stations highlight its national footprint but also raise questions about how evenly capacity is distributed across regions and user segments, with rural and peri-urban areas continuing to experience coverage gaps.
MTN Nigeria remains the market leader, with greater scale and a head start on 5G deployment in major cities. However, its most consequential move may be off the network itself, as MTN finalises a $2.2 billion acquisition of IHS Towers, Africa’s largest tower company. Airtel’s expansion takes on a strategic dimension beyond capacity building, acting as a counterbalance in a market where infrastructure control is becoming increasingly concentrated. Competition is intensifying across the industry, with Globacom upgrading clusters in existing coverage areas and 9mobile focusing on high-traffic urban corridors.
The economics of network expansion remain increasingly strained. A standard 4G site costs between N160 million and N230 million, while 5G macro sites can exceed N500 million. These figures are further inflated by currency depreciation, import dependence, and unreliable grid power, which forces operators to rely on hybrid energy systems or diesel generation, adding a recurring operational burden. Rolling out thousands of sites can push investment into the trillion-naira range, even before factoring in right-of-way charges, land acquisition costs, and security expenditures linked to vandalism and theft.
A deeper structural shift is underway, with Nigeria’s telecom networks once optimised for voice now being reshaped by data-heavy applications such as streaming, cloud computing, and fintech. Capacity has replaced subscriber growth as the key competitive metric, exposing a harder reality: scale alone will not fix Nigeria’s network problem. Without structural changes including cheaper power, lower regulatory costs, and more efficient infrastructure sharing, operators risk pouring billions into a system that still struggles to keep up. In that environment, the real contest is no longer just between MTN Nigeria and its rivals, but between rising demand and the industry’s ability to build a network that can sustainably carry it.
