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.

According to the Nigerian Communications Commission (NCC), this escalation was driven by inflation, exchange rate volatility, growing costs of energy, and above all, inconsistent Right of Way (RoW) fees that continually chokes network expansion across states.

“Most Licensees complained of high Right of Way (RoW) fees, harsh microeconomic operating employment and rising inflation. However, the NCC has been able to secure zero Right of Way (RoW) fees in some States in Year 2024,” the Commission stated in its 2024 industry report.

Uneven Fees, Unequal Access

Despite the Governors Forum’s 2020 resolution setting RoW charges at ₦145 per linear metre, some states have ignored the guideline. Operators disclosed that Ogun State now demands ₦9,477 per metre, the highest nationwide, followed by Lagos (₦6,264) and Oyo (₦5,303).

Others, including Cross River (₦4,737), Rivers (₦4,047), Edo (₦3,491), and Ondo (₦3,075), have also imposed heavy levies. The disparity has slowed broadband rollout, forcing firms to revise deployment plans or suspend network projects entirely.

However, there’s progress. Eleven states have now eliminated RoW fees, according to Dr Aminu Maida, the NCC’s executive vice chairman. “One of the most significant barriers to broadband deployment in Nigeria has been the high RoW fees charged by state governments, despite a resolution by the Nigerian Governors Forum fixing the rate at N145 per linear metre,” he said.

The Commission confirmed that Adamawa, Bauchi, Enugu, Benue, Zamfara, Anambra, Katsina, Kebbi, Nasarawa, Osun, and Plateau have all adopted zero-cost policies to support broadband rollout.

Broadband Goals Falter

The government’s vision to achieve 70% broadband penetration by 2025 is now clearly out of reach. Data from the NCC shows that as of September 2025, penetration stood at 49.3%, well below target.

Experts say the shortfall is financial, not just technical. Each kilometre of fibre delayed by high state fees represents a lost opportunity to extend digital inclusion.

Gbenga Adebayo, chairman of the Association of Licensed Telecommunications Operators of Nigeria (ALTON), said unresolved structural issues are a drag on progress. He pointed to multiple taxation, hidden levies, and high RoW costs as contributing challenges.

He also noted that while some states have waived fees, they continue to impose “education taxes” and “highway levies” under different names, eroding the benefits of those waivers.

High Investment, Shrinking Margins

The NCC report revealed that capital expenditure by telecom operators surged 159% to ₦2.9 trillion in 2024, up from ₦1.12 trillion the previous year. The increase, the Commission said, reveals both aggressive investment in network upgrades and the inflationary impact of the naira’s sharp depreciation following the Central Bank’s exchange rate unification policy.

Telecom companies have spent heavily on 5G rollout, fibre expansion, and network modernisation. Yet, much of that spending has been absorbed by currency losses and rising import costs for equipment.

While revenues climbed 44.7% to ₦7.67 trillion, the profits have barely offset the inflationary and fiscal pressures facing operators, as Nigeria’s telecom costs continually surge.

Tariff Hike Brings Temporary Relief

To ease the burden, the NCC in January 2025 approved a 50% tariff increase for telecom services, a controversial but necessary step, according to industry analysts. The revision allowed major operators, including MTN and Airtel, to return to profitability after reporting significant losses in 2024.

However, the higher tariffs have also limited consumers, particularly low-income users, prompting warnings from advocacy groups about potential digital exclusion in rural and underserved communities.

Policy Flashpoint and the Road Ahead

With telecoms contributing 16.1% to Nigeria’s GDP in Q2 2025, the sector has become the second-largest non-oil contributor to the economy. But then, the persistence of uneven RoW charges has turned the issue into a national policy flashpoint.

Stakeholders are now urging federal intervention to harmonise fees nationwide, arguing that broadband rollout, essential for education, finance, and digital commerce, should not depend on a state’s internal revenue strategy.

For Nigeria’s competitive edge to remain, policymakers must choose between short-term state revenue and long-term national connectivity, ensuring telecom costs are reduced. The choice, as the numbers show, can no longer be delayed.
