Nigeria’s mobile telecom market is becoming increasingly concentrated around its two largest operators, MTN Nigeria and Airtel, as Globacom (Glo) loses subscribers and the latest figures for T2 Mobile remain unchanged because the operator did not submit updated data to the regulator.

The latest subscriber statistics published by the Nigerian Communications Commission (NCC) show just how dominant the two largest networks have become.

As of June 2026, MTN had 98.64 million active subscribers, representing about 51.4% of the market, while Airtel had 66.12 million, or approximately 34.4%.

Glo had 23.68 million subscribers, representing about 12.3%, while T2 Mobile accounted for approximately 3.54 million, or 1.8%.

Together, MTN and Airtel therefore accounted for roughly 85.8% of active mobile subscribers in the NCC's June figures.

That concentration matters because the number of credible alternatives available to consumers can influence everything from pricing and network investment to customer service and service quality.

But the latest data also comes with an important warning: not every number in the NCC's table necessarily represents a fresh subscriber count.

T2 Mobile’s unchanged numbers are not evidence of a flat subscriber base

T2 Mobile's figures remained unchanged across the latest reporting period because the company did not submit updated subscriber information to the NCC.

The regulator states that its industry statistics are compiled from the latest information submitted by operators by the reporting deadline.

That means an identical figure appearing across several months should not automatically be interpreted as proof that the operator gained or lost no customers.

The issue is particularly important because subscriber movement data suggests that T2's customer base was changing during the period.

According to the data cited in reports on the matter, 73 subscribers ported their numbers to T2 while 1,897 moved away from the network, representing a net loss of 1,824 subscribers through number portability alone.

The NCC reportedly attributed T2's inability to submit updated figures to technical challenges.

That leaves the operator's actual subscriber position during the period unclear.

And that is more than a statistical inconvenience.

Reliable market data is important for understanding whether smaller operators are genuinely gaining traction, losing customers or simply failing to report their latest performance.

Glo's decline is more visible

Unlike T2, Glo's subscriber movement is visible in the available data.

The company recorded growth between April and May but then suffered a significant decline in June.

Glo's subscriber base increased by approximately 7.8% between April and May, but then fell by about 7.3% in June, effectively wiping out the previous month's gain.

That left the operator with fewer subscribers than it had at the beginning of the period.

The decline raises questions about customer churn and the competitive pressure facing Nigeria's third-largest major mobile operator.

But subscriber losses should not automatically be interpreted as evidence that Glo is simply providing an inferior service.

Nigeria's telecom operators are dealing with infrastructure problems that can affect network performance regardless of how much money is invested in expansion.

Nigeria's fibre infrastructure is under growing pressure

One of the biggest challenges facing telecom operators is damage to the physical infrastructure supporting mobile and internet services.

The NCC said more than 5,000 fibre-optic cable cuts were recorded across Nigeria during the first six months of 2026, with road construction, excavation and other civil works contributing to the problem.

The regulator has warned that damage to fibre infrastructure can disrupt telecommunications services and affect banking, government services, education, healthcare, commerce and other parts of the economy.

That creates a difficult situation for network operators.

A customer experiencing slow data, dropped calls or intermittent connectivity may blame the telecom company and switch networks.

But the underlying cause could be a damaged fibre route, vandalised infrastructure or an operator being unable to access a location where repairs are required.

The result is the same from the customer's perspective: the service does not work.

That makes network reliability one of the most important factors in determining whether customers remain loyal.

MTN and Airtel continue to pull ahead

While Glo has been losing ground, MTN and Airtel have continued to expand their subscriber bases.

MTN's active mobile internet subscriber base increased by about 0.68% between April and June, while Airtel recorded stronger growth of approximately 2.81% over the same period.

Airtel's performance included an increase of roughly 1.47 million subscribers in June alone, according to the reported figures.

The result is a market in which the two biggest operators continue to strengthen their position while smaller competitors struggle to maintain momentum.

This does not necessarily mean competition has disappeared.

It does, however, mean the competitive weight of the market is increasingly concentrated in two companies.

Why market concentration matters to consumers

For the average Nigerian mobile user, market share may sound like a corporate statistic.

In practice, it can affect everyday experiences.

When several operators compete aggressively for customers, they have stronger incentives to offer better prices, improve network coverage, introduce new services and respond quickly to customer complaints.

When fewer companies control most of the market, that competitive pressure can weaken.

This becomes particularly important in Nigeria because mobile connectivity is no longer a luxury.

People rely on telecom networks for banking, work, education, social communication, entertainment, e-commerce and access to government services.

For many Nigerians, losing reliable connectivity can mean losing access to essential economic activities.

A concentrated telecom market therefore puts greater importance on regulation and service-quality enforcement.

The smaller operators face a difficult battle

The gap between the largest operators and smaller players illustrates the challenge of competing in Nigeria's telecom industry.

Building and maintaining a nationwide network requires enormous investment.

Operators have to spend on spectrum, base stations, fibre, power, backhaul, maintenance, security and other infrastructure.

They also have to deal with rising operating costs and the physical challenges of maintaining infrastructure across a large country.

The larger operators benefit from scale.

More subscribers can mean more revenue to fund network investment, marketing and expansion.

Smaller operators have to compete for customers while operating with a smaller revenue base.

That can make it harder to match the network investments of the market leaders.

T2's reporting issue exposes another problem

The T2 situation highlights a different challenge: transparency in market data.

A regulator's subscriber statistics are only as useful as the information available to it.

If an operator cannot provide updated figures, analysts, investors and consumers lose visibility into what is actually happening within that part of the market.

The NCC has made clear that its published figures are based on the latest operator submissions it has received.

This is why unchanged numbers should be treated carefully.

A flat line in a regulatory table does not necessarily mean a flat business.

In T2's case, the available number-porting data suggests that customers were moving both into and out of the network during the period.

Until updated subscriber data is submitted, the operator's precise position remains uncertain.

Nigeria's telecom market is entering a different phase

For years, the major story in Nigeria's telecommunications industry was subscriber growth.

The market was expanding rapidly as more Nigerians acquired mobile phones, smartphones and mobile internet connections.

The situation is now different.

Nigeria has a huge established mobile market, meaning operators increasingly have to compete for existing customers rather than simply relying on millions of new users entering the market.

That makes customer retention increasingly important.

Network quality, data pricing, call quality, customer service and reliability can all determine whether a customer stays with one operator or moves to another.

Number portability makes that switching process easier because customers can change networks without necessarily giving up their existing phone numbers.

That increases the pressure on operators to keep customers satisfied.

The infrastructure problem could reshape competition

There is another dimension to the story.

If fibre cuts, vandalism, power challenges and access problems continue to disrupt networks, operators with stronger infrastructure resilience could gain an advantage.

But infrastructure resilience requires investment.

The NCC's warning about more than 5,000 fibre cuts in six months demonstrates how much damage can occur outside an operator's direct control.

This means Nigeria's telecom competition cannot be viewed only through the lens of subscriber numbers.

The quality and resilience of the infrastructure behind those numbers matter just as much.

A network can have millions of subscribers and still struggle if its underlying infrastructure is repeatedly disrupted.

What this means for MTN and Airtel

For MTN and Airtel, the latest figures reinforce their position as Nigeria's dominant telecom operators.

But greater market share also brings greater responsibility.

With millions of Nigerians dependent on their networks, service disruptions can affect a significant portion of the country's digital economy.

The operators will need to continue investing in network capacity, fibre resilience, 4G and 5G infrastructure and customer support.

They will also face increasing expectations around affordability.

Having the largest subscriber base gives an operator scale, but it does not eliminate competition.

Customers can still switch when they find better prices or better service.

What Glo and T2 need to solve

For Glo, reversing subscriber losses will likely require more than aggressive promotions.

The operator needs to understand why customers are leaving and whether network quality, pricing, customer service, coverage or other factors are driving the churn.

For T2, restoring the flow of reliable market data is an immediate priority.

Without updated figures, it becomes difficult for the market to accurately assess the operator's performance.

For both companies, the challenge is the same at a higher level: how do smaller operators remain relevant when the two largest players control more than four-fifths of the market?

The bigger story for Nigeria's digital economy

The latest subscriber numbers reveal something larger than a battle between telecom companies.

Nigeria's digital economy increasingly depends on a small number of networks.

That creates both efficiency and risk.

Large operators have the scale to make major infrastructure investments, but concentration can also make disruptions more consequential and reduce the number of meaningful alternatives available to consumers.

The answer is not necessarily to prevent successful operators from growing.

Instead, regulators need to ensure that competition remains meaningful, smaller operators have a fair opportunity to compete, infrastructure providers can build resilient networks and consumers are protected when service quality falls below expectations.

The NCC's latest data shows a market moving further toward MTN and Airtel.

The question now is whether Nigeria can maintain enough competitive pressure to ensure that bigger does not become synonymous with less choice, higher prices or weaker service.

For consumers, that is the part of the telecom story that matters most.

Nigeria's telecom market is not simply becoming bigger—it is becoming more concentrated.

MTN and Airtel's combined share is now overwhelming, while Glo is losing ground and T2's latest figures cannot provide a clear picture because of a reporting problem.

That does not automatically mean consumers are worse off today.

But it does mean competition deserves closer attention.

The strongest telecom market is not necessarily one with the most operators. It is one where operators have enough competitive pressure to keep prices reasonable, networks reliable and customers properly served.

As Nigeria becomes more dependent on digital services, keeping that pressure alive will become increasingly important.
