But then, here we are. The sector’s contribution to the economy is so massive that ignoring it would be like pretending petrol isn’t essential to your car just because the tank is full.

It grew at a real rate of 5.78% in Q3 2025 and accounted for roughly 9.1% of GDP, proving that even in a country notorious for regulatory tangles and infrastructural challenges, telecoms are the backbone of modern Nigeria.

But don’t be deceived by these figures, there’s still a world of congestion, fibre cuts, high expenses, and millions of frustrated subscribers tapping the screen for just one uninterrupted call.

Subscriber Growth and Broadband Penetration: Two Extremes

Active mobile subscriptions hit ~169.3 million in January, growing steadily to 175 million by December, nudging teledensity past 80%, the highest since early 2024. 

We could call this progress since Nigerians are connecting, surfing, streaming, and transacting digitally more than ever. Broadband adoption, too, edged towards 50%, with nearly 49.9% penetration by December 2025, inching closer to the National Broadband Plan’s 70% target.

However, numbers can be deceiving. While urban dwellers bask in fibre-optic speeds and 4G coverage, rural users are fighting with patchy signals and pricey data, nudging us that half the population is still a click away from the digital economy.

Investment, Tariffs, and Infrastructure

Telecom operators collectively poured ~₦824.7 billion into network expansion in H1 2025 alone. Add $1 billion in projected infrastructure investment and the government’s approval of 7,000 new towers, and it looks like Nigeria’s networks are finally meeting up with demand.

Tariff reforms, including a 50 % headroom on pricing, spurred roughly $2 billion in equipment imports, showing serious investor assurance. 

Still, operators battled record operational costs of ~₦5.85 trillion, thanks to energy expenses, multiple taxes, and the notorious Right of Way fees. Growth may be visible on the surface, but the price of keeping the lights, and signals, on is still a big issue.

Technology Deployment: 4G Dominates, 5G Stutters

4G remained king, covering more ground and enabling surges in data consumption. 5G, on the other hand, limped along at ~3.4 % market share, limited by device affordability and limited rollout. 

It’s a classic story where infrastructure exists, purpose exists, but the average Nigerian smartphone wallet does not.

The pledge of next-gen connectivity is there, but the reality is uneven adoption. Even as data usage peaked at 1.15 million terabytes in August, a noteworthy portion of the population is left waiting for the high-speed revolution.

Operator Performance: Leaders, Survivors, and Stragglers

MTN Nigeria retained its crown with ~90.33 million subscribers (~52 % market share). Data revenue surged 69.2 %, while voice grew 40.3 %, enabling MTN to swing from an operating loss in 2024 to a profit in H1 2025. 

The operator also struck a national roaming and spectrum sharing agreement with 9mobile to ease coverage gaps.

Airtel Nigeria was the second-largest operator, hovering around ~58.47 million subscribers (~34 % market share). Its mobile money platform boosted digital revenue, while strategic tariff adjustments helped maintain steady growth.

Globacom recovered modestly to ~21.39 million subscribers (~12 %), but growth lags behind MTN and Airtel, reflecting lingering regulatory and competitive challenges.

9mobile, the smallest operator in terms of numbers, barely moved the needle at ~3.11 million subscribers (~1.8 %). Its mid-year infrastructure-sharing deal with MTN produced minimal subscriber growth, stressing the uphill battle against market authority and service quality issues.

The Dark Side of 2025: Costs, Complaints, and Inequalities

Despite subscriber growth, users complain of slow internet, frequent signal drops, and service congestion. 

Inflation and naira depreciation pushed tariffs higher, leaving low-income households increasingly excluded. Even with near-50% broadband penetration, rural areas lag badly, sustaining a stubborn digital divide.

Infrastructure vandalism and fibre cuts added to the challenge, while regulatory stress and multiple levies, up to 18-20 taxes per service, kept operators constantly on edge. 

Add delayed privatisation of NATCOM and stalled 5G expansion, and it’s apparent that 2025 was a high-wire balancing act, with massive growth shadowed by operational and structural challenges.

Data Usage and Digital Consumption

Data consumption drove Nigeria’s telecom sector growth in 2025. GSM internet subscribers reached 140.36 million, and monthly traffic peaked at 1.15 million terabytes. 

These trends show a high dependency of Nigeria’s population on mobile internet for work, entertainment, education, and finance. It’s a digital sector expanding speedily, even if unevenly.

Policy and Regulatory Space

The government removed a 5% telecom tax mid-year, though analysts warned it wouldn’t automatically lower prices for consumers. 

NCC’s robust monitoring and reporting framework ensured operators stayed accountable, but the environment remained heavy with compliance requirements. 

Regulatory complexity continues to shape strategic decisions, especially for operators outside the top two.

2025 in Summary: Progress with Strings Attached

• The Good: Subscriber numbers hit record highs, broadband approached 50%, GDP contribution remained strong, and 4G/5G coverage expanded steadily.
• The Bad: High operational expenses, affordability limitations, service quality issues, uneven rural coverage, and slow 5G adoption.
• Operator Reality: MTN tops, Airtel holds steady, Globacom recovers slowly, 9mobile struggles.

Nigeria’s telecom sector in 2025 is a study in contrasts, incredible growth and investment, paired with structural and operational challenges. 

If the past year teaches us anything, it’s that subscriber numbers and GDP contribution are not the entire measure of success. Can expansion be turned into reliable, affordable, and inclusive service? So that the mobile revolution benefits not just the urban elite, but the entire nation.

The latest figures from the Nigerian Communications Commission (NCC) show that data consumption reached 1.04 million terabytes in May 2025, the highest since official tracking began in January 2023. 

This is an increase from April’s 983,283 terabytes and even surpasses January 2025’s earlier peak of 1 million terabytes.

What’s driving this? It’s certainly not more users. Internet subscriptions actually dropped in May. Total connections across mobile, fixed, wired, ISPs, and VoIP networks fell from 141.9 million in April to 141.5 million. In plain terms, nearly 400,000 Nigerians went offline.

The reason is that the 50% price hike that telecom operators introduced in January 2025 is forcing many Nigerians to rethink their connectivity habits. 

The NCC-approved increase pushed call rates from ₦6.40 to ₦9.60 per minute, SMS from ₦4 to ₦6 per message, and 1GB of data from ₦287.50 to ₦431.25.

For countless subscribers, this has meant hard choices. Many now favour flexible or weekly plans over monthly bundles. Secondary SIMs are being abandoned to cut costs. 

Nonetheless, those who remain connected are using more data than ever. Average monthly data consumption per user soared to 9.86GB in May 2025, a 30.9% jump compared to the same month last year.

With smartphone penetration at 59% in cities and 26% in rural communities, data has evolved from a luxury to a necessity. Whether for video calls, streaming, online learning, or endless social media scrolling, Nigerians are now consuming heavier content.

However, not every operator is losing subscribers. MTN and 9mobile recorded notable declines. MTN, despite leading the market, lost 258,313 subscribers in May, while 9mobile shed 291,214 users. MTN’s base now stands at 90.2 million; 9mobile has declined to 2.6 million.

In contrast, Airtel added 342,597 subscribers, pushing its customer count to 58.9 million. Globacom remained flat, maintaining 20.6 million active lines. Nevertheless, MTN still controls over half the market, 52.33% to be exact, while Airtel holds 34.17%, Glo 11.96%, and 9mobile trails with just 1.55%.

These subscription declines also dragged down Nigeria’s overall teledensity to 79.65% in May from 79.78% in April. Teledensity, based on a population estimate of 216 million, indicates the ratio of active lines to people in the country.

Meanwhile, the country’s telecom sector is attracting record investment. In 2025 alone, Nigeria secured $1.15 billion in data centre and cloud infrastructure funding. 

This includes MTN’s $285 million Tier III Dabengwa Data Centre, Kasi Cloud’s $250 million hyperscale facility, and OADC’s $240 million AI-ready campus in Lagos. These facilities aim to localise data, reduce latency, and bolster Nigeria’s push for digital sovereignty.

Still, the price competition between mobile data and fixed broadband is changing internet access. Providers like FibreOne, Spectranet, and Starlink lost over 18,000 subscribers in the first quarter of 2025. 

Hardware costs, combined with tariff hikes, are pushing consumers towards cheaper mobile alternatives. As it stands, mobile operators now handle over 99% of Nigeria’s internet traffic.

Nigeria’s telecom sector is shrinking in subscriber bases but growing in data consumption. Mobile data revenue is projected to hit $13.4 billion by the end of 2025. The broader telecom market, valued at $9.52 billion this year, is expected to reach $11.97 billion by 2030.
