Nigeria’s telecommunications sector has grown steadily over the past two decades, evolving from a voice-driven market into a data-focused ecosystem that supports digital services, financial inclusion, and content creation. Beneath this expansion, a significant shift is occurring, with two operators consolidating their dominance and capturing a growing share of the market.
Latest data from the Nigerian Communications Commission (NCC) shows that MTN Nigeria and Airtel Nigeria together control approximately 86 percent of Nigeria’s mobile subscriber base, underscoring a growing imbalance in an industry that was once more competitively distributed.
MTN Nigeria retains its position as the market leader, with 95.3 million subscribers, representing a 51.69 percent share. Airtel Nigeria follows with 63 million users and a 34.18 percent share. Combined, both operators account for the vast majority of active mobile lines in the country, effectively shaping the direction of the industry.
By contrast, Globacom holds 22.6 million subscribers, translating to a 12.26 percent market share, while 9mobile now operating under the T2 brand, has seen its footprint shrink reasonably to 3.4 million users, representing just 1.87 percent of the market.
This widening gap reflects more than just subscriber numbers. It indicates a structural transformation in Nigeria’s telecom landscape, where scale, sustained capital investment, and superior data infrastructure have become the primary determinants of market leadership.
The shift becomes even more pronounced when viewed through the lens of internet usage. As of February 2026, Nigeria recorded a total of 152.5 million active internet subscriptions on GSM networks. Within this segment, MTN and Airtel again dominate.
MTN leads with 82.2 million internet subscribers, while Airtel follows with 54.1 million, together accounting for the bulk of Nigeria’s data users. This reinforces their position not just as telecom operators, but as critical enablers of the country’s fast-growing digital economy.
The implications are far-reaching. Increasingly, Nigeria’s telecom competition is no longer defined by voice services but by the ability to deliver fast, reliable, and scalable data connectivity. From video streaming and remote work to fintech services and social media content creation, user behaviour is shifting rapidly toward high-bandwidth applications.
As a result, subscribers are gravitating toward networks perceived to offer stronger coverage, faster speeds, and more consistent performance factors that have largely favoured MTN and Airtel.
Revenue growth mirrors data dominance
Financial performance across both operators further highlights how data is reshaping the industry.
MTN Nigeria delivered one of its strongest results in recent years, posting ₦5.2 trillion in service revenue for the year ended December 31, 2025, representing a 55.1 percent year-on-year increase. The growth was largely driven by a 74.5 percent surge in data revenue, which rose to ₦2.78 trillion.
The company’s operational metrics tell a similar story. Active data users grew by 11.6 percent to 53.2 million, while total data traffic climbed 34 percent. Average monthly data consumption per user increased by 20 percent to 13.1GB, alongside a rise in smartphone penetration to 66.1 percent.
These figures point to a deeper trend, showing that not only are more Nigerians coming online, but they are also consuming significantly more data,reinforcing the importance of network capacity and quality.
Airtel’s performance in Nigeria follows a similar trajectory. According to its nine-month results for the period ended December 31, 2025, revenue grew by 50.4 percent in constant currency, driven largely by sustained demand for data services and supported by tariff adjustments.
The growth was underpinned by a 39.6 percent increase in average revenue per user (ARPU) and a 7.8 percent expansion in its customer base. In reported currency terms, revenue rose by 52.1 percent to $1.12 billion, with even stronger quarterly growth supported by currency movements.
Voice revenue, while still relevant, is increasingly secondary. Airtel reported a 35.8 percent growth in voice revenue in constant currency, driven by tariff adjustments and improved ARPU, but the broader momentum continues to come from data services.
Investment gap widens industry divide
At the core of this growing dominance lies a widening investment gap. MTN and Airtel have consistently channelled significant capital into expanding coverage particularly in 4G and 5G, upgrading tower infrastructure, and extending fibre networks across the country.
These investments are not merely incremental; they are shaping user experience in a way that reinforces subscriber loyalty and attracts new users. In a market where network quality directly influences daily digital activities, infrastructure has become a key competitive moat.
Independent performance data supports this trend. According to the nPerf Barometer of Mobile Internet Connections in Nigeria for 2025, MTN ranked highest overall, scoring 37,106 points, ahead of Airtel with 25,614 points and Globacom with 20,475 points.
MTN led across multiple performance indicators, including average download speeds of 18.65 Mbps, upload speeds of 8.70 Mbps, and latency of 96.46 milliseconds. The network also maintained strong consistency during peak usage periods, making it particularly suited for video streaming, remote work, and content creation.
Airtel ranked second, delivering competitive performance with average download speeds of 10.57 Mbps and upload speeds of 4.74 Mbps. The operator also demonstrated strong capabilities in video streaming, reinforcing its position as a viable alternative for data-intensive users.
Globacom, while trailing in overall performance, recorded the lowest latency among competitors at 121.81 milliseconds, indicating relative strength in delay-sensitive applications, even as broader network performance remains less competitive.
Notably, MTN accounted for 58 percent of all tests analysed in the report, suggesting both widespread usage and a higher level of user engagement with its network.
From balanced competition to market concentration
Over a decade ago, Nigeria’s telecom market presented a more balanced competitive landscape. Operators such as Globacom and what was then Etisalat (now T2) held stronger positions, offering viable alternatives to the market leaders.
However, a combination of financial strain, ownership transitions, and underinvestment has reshaped that dynamic. 9mobile, in particular, has experienced a significant erosion of its subscriber base over the years, despite recent rebranding efforts under the T2 identity aimed at repositioning the business.
Subscriber movement data further illustrates the challenge. NCC figures show that 9mobile recorded the highest number of outgoing porting activities as of February 2026, with 1,018 subscribers leaving the network for competitors. Globacom followed with 381 outgoing ports, while Airtel and MTN recorded significantly lower figures at 241 and 195 respectively.
The pattern reflects a continued migration of users toward networks perceived to offer better service quality, further reinforcing the dominance of the leading operators.
The trajectory of Nigeria’s telecom sector is increasingly defined by scale and technological capability. Rising demand for high-speed data suggests that operators with the financial capacity to sustain network investment are likely to maintain their market advantage.
Industry analysts suggest that smaller operators may require strategic repositioning, targeted investments, or a focus on niche markets to remain competitive in a landscape dominated by larger providers. Evolving user needs from content creators and entrepreneurs to remote workers and everyday consumers are driving market dynamics, making consistent, high-quality connectivity a baseline expectation for all networks.
In this context, MTN and Airtel’s current dominance reflects not just their size, but their alignment with the direction in which the market is moving. The real question is no longer who leads today, but whether the gap between the leaders and the rest of the market will continue to widen in the years ahead.
