MTN Nigeria has marked 25 years of commercial operations in the country with 92.2 million subscribers, highlighting the dramatic expansion of telecommunications infrastructure since mobile services became commercially available in 2001.
The milestone comes as the company continues to invest heavily in network capacity, fibre infrastructure and newer technologies to meet rapidly growing demand for mobile data.
Nigeria had only about 22,500 cellular lines and 700,000 fixed lines when MTN began commercial operations in 2001, despite a population of roughly 120 million at the time. A quarter of a century later, mobile connectivity has become a critical part of everyday economic and social activity.
From 22,500 Lines to Mass Connectivity
MTN’s expansion mirrors the broader transformation of Nigeria’s telecommunications sector.
The company initially built its network around major cities including Lagos, Abuja and Port Harcourt before extending coverage across the country. As its subscriber base grew, the operator expanded its base stations, transmission systems, core network and supporting power infrastructure.
MTN crossed one million subscribers during its early years, reached 10 million in 2006 and surpassed 50 million subscribers by 2013.
The evolution of the network also followed changes in how Nigerians use telecommunications services. The early focus on voice and text messaging gradually gave way to mobile internet, digital payments, social media, streaming and other data-intensive services.
MTN was among the operators that deployed 3G/HSPA+ technology in Nigeria in 2008 before subsequently expanding into 4G. Its 5G rollout has continued, with the technology reaching approximately 13% population coverage in the company’s latest reported figures.
Data Usage Puts New Pressure on Infrastructure
The company’s network now serves far more than voice calls.
MTN had 55.7 million active data users at the end of June 2026, reflecting the rapid migration of Nigerians toward internet-based services.
The increase in video streaming, online learning, digital banking, social media and business communications has created significantly greater demand for network capacity.
More smartphones and heavier data consumption require operators to continuously upgrade radio equipment, expand transmission capacity and deploy additional fibre connecting base stations to the core network and the wider internet.
This also helps explain why network quality remains a challenge in some locations despite continuing investment. Congestion, fibre cuts, transmission constraints, equipment limitations and power interruptions can affect service quality even where geographic coverage is extensive.
Power Costs Remain a Major Challenge
The economics of maintaining Nigeria’s telecom infrastructure remain difficult.
Network sites require reliable electricity, but inconsistent grid supply means operators and infrastructure companies often depend on generators, batteries, solar systems and other backup solutions.
MTN Nigeria’s Chief Technical Officer, Yahaya Ibrahim, identified unreliable electricity, high diesel costs, vandalism, fibre cuts and difficult access to certain locations among the challenges confronting telecom operators.
The depreciation of the naira and elevated inflation have also increased the cost of imported network equipment, maintenance and expansion.
For a network serving more than 90 million people, keeping thousands of sites operational therefore requires substantial and continuous spending.
₦621bn Invested in First Half of 2026
MTN has responded to rising demand by increasing investment in network expansion and capacity.
The company invested approximately ₦621 billion in capital expenditure during the first six months of 2026, according to its latest results.
The spending has been directed toward network expansion, capacity upgrades, fibre infrastructure and newer technologies, including 4G and 5G.
The company’s strategy is increasingly focused not just on extending coverage to new locations but also on improving the resilience and capacity of existing infrastructure.
However, technology upgrades alone cannot resolve all network challenges. Reliable electricity, protection of fibre routes, access to infrastructure and policies that encourage continued investment remain critical to improving service quality.
Telecom Economics Have Become More Difficult
MTN’s expansion has taken place against a backdrop of rising operating costs.
The naira has weakened substantially since the company’s Nigerian operations began, while inflation, fuel prices and the cost of imported equipment have increased.
Telecom operators have also faced regulatory and compliance pressures.
One of the most significant episodes came in 2015, when the Nigerian Communications Commission imposed an initial $5.2 billion fine on MTN over improperly registered SIM cards. The penalty was eventually reduced to $3.9 billion.
The episode demonstrated the increasingly important role of telecommunications infrastructure in national policy, particularly around identity management, security, taxation and consumer protection.
Connectivity Becomes Economic Infrastructure
The significance of MTN’s network now extends beyond telecommunications.
Mobile connectivity enables businesses to receive digital payments, reach customers through social media and communicate with suppliers. Students can access online educational resources, freelancers can work with international clients, while creators can distribute their work to audiences beyond Nigeria.
Banks, retailers, logistics companies, media organisations and government institutions also increasingly depend on reliable digital connectivity.
This means the economic value of telecom infrastructure cannot be measured solely by the revenue generated by operators. Its wider importance lies in the businesses, services and economic activities that connectivity makes possible.
Rural Connectivity Remains Unfinished Business
Despite the dramatic expansion of mobile services, significant gaps remain.
Extending infrastructure to rural communities can be considerably more expensive because operators must build and power sites that may serve fewer customers than those located in densely populated cities.
As a result, the next phase of Nigeria’s connectivity journey is shifting from simply getting people online to ensuring that internet access is reliable, affordable and sufficiently capable to support meaningful participation in the digital economy.
MTN Nigeria CEO Karl Toriola acknowledged that the company’s work remains incomplete, noting that millions of Nigerians still require better access to digital services.
The Next 25 Years
MTN’s first quarter-century in Nigeria demonstrates how private investment, spectrum allocation, regulation and technological development can transform national communications infrastructure.
The company has moved from a market in which mobile phones were largely inaccessible to a network serving more than 92 million subscribers.
But sustaining that progress will require continued investment in fibre, spectrum, power, network capacity and newer technologies, alongside measures to make connectivity more resilient and affordable.
For MTN Nigeria, the next chapter will therefore not be defined solely by how many additional subscribers it can connect. The bigger test will be whether its infrastructure can support the country’s growing digital economy while remaining reliable and accessible to the millions of Nigerians who increasingly depend on it.
