MTN Nigeria’s 100 million active-subscriber base is opening a bigger market for data, fintech and other digital services, giving the operator greater room to grow revenue as Nigerians increasingly shift from voice calls to mobile internet and digital transactions.
MTN ended July with 100.86 million active subscriptions, up from 98.64 million in June, according to the latest data from the Nigerian Communications Commission (NCC). It is the first Nigerian telecom operator to cross the 100 million mark, giving MTN 51.76 percent of the country’s 195.11 million active mobile subscriptions.
The milestone comes as Nigeria’s mobile market approaches 200 million active lines and consumers increasingly depend on networks for data, digital payments, streaming, business and other online services.
The operator added about 2.22 million subscribers in July, its strongest monthly growth so far this year and its biggest increase since November 2024. From about 94.25 million subscribers in January, MTN added more than 6.6 million lines in seven months, representing growth of about seven percent.
That translates to roughly 31,000 additional subscribers a day since the beginning of the year.
The wider market is also expanding rapidly. Active subscriptions increased from 182.23 million in January to 195.11 million in July, adding 12.88 million lines. Teledensity rose from 84.06 percent to 90 percent over the same period.
MTN is capturing a significant share of that growth, widening its lead over rivals. Airtel ended July with 66.76 million subscribers and a 34.26 percent market share, while Globacom had 23.63 million and T2 Mobile 3.61 million. MTN and Airtel now account for more than 86 percent of Nigeria’s active mobile subscriptions.
The scale of MTN’s growth means its network is carrying an increasingly large share of Nigeria’s mobile traffic. But the bigger question for MTN is whether its network infrastructure can keep pace with the growth.
The company spent N620.5 billion ($449.6 million) on capital expenditure in the first half of 2026, excluding lease additions, with investments directed towards spectrum, fibre backhaul and other network infrastructure.
The spending reflects the increasing capital intensity of running Nigeria’s largest mobile network. More subscribers require more sites, spectrum capacity, fibre backhaul and other infrastructure, particularly as customers consume significantly more data than they did when voice services dominated telecom revenues.
MTN’s own financial performance shows where the commercial opportunity lies. The company generated about N1.7 trillion in data revenue in the first half of 2026, making data an increasingly important driver of its business.
Its 100-million-plus customer base gives MTN a huge market from which to grow data consumption while expanding into fintech and other digital services. The more customers use smartphones, mobile broadband, digital payments and financial services, the greater the revenue opportunity attached to each subscriber.
But that opportunity depends on network quality.
The NCC has recently acknowledged growing complaints over dropped calls, slow internet speeds, congestion and unstable services, saying operators are undergoing one of the sector’s biggest network expansion and modernisation cycles following years of under-investment.
Aminu Maida, NCC executive vice chairman, has repeatedly stressed the need for operators to increase network investment and improve quality of service. The regulator said operators committed to upgrading 12,000 network sites in 2026, compared with just over 3,000 upgrades in 2025.
The upgrades include adding capacity to existing 4G sites and converting older 2G and 3G infrastructure to 4G and 5G.
The NCC has also pointed to measurable improvements, with national median download speeds rising from 16.5Mbps in January 2024 to about 20Mbps, while 4G penetration has increased from 45 percent to 54 percent. More than 730 additional 5G sites have also been deployed across 27 states in 2026.
Yet network complaints remain widespread, highlighting a central problem for the industry: investment is increasing, but demand is rising at the same time.
The pressure is not only coming from subscriber numbers. Data consumption is increasing as Nigerians use mobile networks for video, social media, cloud services, digital payments and increasingly sophisticated applications.
For MTN, this means adding subscribers is only one part of the growth equation. The company must also increase the amount of capacity available to each customer if it wants to convert its 100 million subscribers into sustainable data and digital revenue.
Infrastructure damage is another constraint. Fibre cuts caused by road construction, excavation and vandalism continue to disrupt telecom services. Even where operators have invested in additional network sites, damaged fibre infrastructure can affect the backhaul connecting those sites to the wider network.
This makes MTN’s capital spending critical, but also highlights why network investment alone may not immediately eliminate poor service.
The company now faces the challenge of staying ahead of two curves: subscriber growth and data consumption. Its July milestone shows that demand for MTN’s network remains strong, but it also means that any capacity shortfall could affect a much larger number of Nigerians.
The commercial stakes are equally high. With more than 100 million active subscriptions, MTN has an unprecedented customer base to monetise through data, fintech, home broadband and other digital services.
The challenge is ensuring that the network supporting those services grows faster than demand.
MTN’s 100-million milestone therefore represents both a major commercial opportunity and a warning on infrastructure capacity. As Nigeria moves towards 200 million active mobile subscriptions, the next phase of competition may be determined less by who can attract the most SIMs and more by who can provide enough reliable capacity to keep increasingly data-hungry customers connected.
