Nigeria shatters data consumption record as 4bn gigabytes devoured in Q1 2026

Nigerians consumed more than four billion gigabytes of internet data in the first three months of 2026, marking a new quarterly record that highlights the country’s rapid shift towards a digital economy.

Data from the Nigerian Communications Commission (NCC) showed total consumption reached 4.06 million terabytes in the January-to-March period.

One terabyte equals roughly 1,000 gigabytes, pushing the three-month total well above four billion gigabytes. This surpassed the previous high of 3.86 million terabytes set in the final quarter of 2025.

March proved the busiest month on record, with 1.42 million terabytes consumed, a sharp rise from 1.26 million terabytes in February. Average daily usage in March climbed to about 45,896 terabytes, compared with 45,002 terabytes per day the previous month.

The surge comes as more Nigerians go online for social media, video streaming, mobile payments, and other digital services.

Internet subscribers rose by over 650,000 to reach 153.82 million in March, driven largely by mobile connections. Total telecom users in the country now stand at 185.7 million.

Infrastructure strain and investment

Moving such large volumes of data requires significant network capacity. Nigeria’s telecom operators have responded with heavy spending. MTN Nigeria, the market leader, invested about N1 trillion (roughly $727 million) in network upgrades last year.

Airtel committed hundreds of millions of dollars, while Globacom expanded its fibre footprint.These investments support a vast infrastructure of undersea cables, nationwide fibre optic lines, and more than 20,000 telecom towers operating at high capacity.

Aminu Maida, the executive vice chairman of the NCC, revealed that over $1 billion will be invested on telecom infrastructure this year, surpassing total industry spending in the previous year.

Older 2G and 3G networks continued to lose ground in the first quarter, declining to 36.75 percent and 5.30 percent of connections respectively.

In contrast, 4G now accounts for 53.79 percent of all connections, up slightly from February. 5G, still in early stages, holds a 4.2 percent share but carries a growing share of heavy data traffic in cities like Lagos and Abuja.

On 5G, Maida acknowledged that deployment remains slow compared to 4G, but described this as a natural progression. Like previous technologies, 5G adoption is constrained by factors such as device availability, cost, and infrastructure readiness.

Globally, he noted, 5G has yet to match the scale and maturity of 4G, and Nigeria is no exception. However, he expressed confidence that adoption will accelerate over time as enabling conditions improve.

Maida explained that the sector is only beginning to recover from a prolonged period of underinvestment, which created the congestion and service gaps Nigerians currently experience. According to him, the scale of ongoing infrastructure expansion signals a turning point.

While operators deployed just over 300 new or upgraded sites last year, the industry has committed to about 12,000 site upgrades in 2026 alone. Already, about 2,800 upgrades have been completed, including new sites, capacity expansion, and the transition from older 2G and 3G infrastructure to more efficient 4G and emerging 5G networks. This, he noted, places the industry significantly ahead of last year’s pace and demonstrates renewed investor confidence.

He added that improvements in quality of service are already being observed in key metrics such as data speeds, although challenges like latency persist. The Commission’s continuous monitoring, supported by quarterly performance reports, shows that while the trend is positive, the user experience is still uneven and requires sustained effort.

A major driver of recent improvements, the NCC boss explained, is the strategic expansion and redistribution of spectrum resources. Through spectrum trading and reallocation, about 100 MHz of previously underutilised spectrum has been made available to operators. This has effectively widened the “digital highways” that carry telecom traffic, improving both coverage and speed.

He noted that different spectrum bands serve different purposes—lower frequencies support rural coverage, while higher bands enhance capacity in densely populated urban areas. The recent spectrum assignments have enabled operators to upgrade networks more efficiently, contributing to noticeable gains in data performance, particularly in the first quarter of the year.

The EVC emphasized that these investments must be additional to already planned capital expenditure for 2026, not a reallocation of existing budgets.

To ensure compliance, independent auditors will verify all claimed investments, preventing operators from diverting funds or misrepresenting expenditures. He stressed that this approach reflects the Commission’s broader philosophy of redirecting value back to consumers and strengthening network capacity rather than imposing purely financial penalties.

Fixed internet subscriptions also rose 10.02 percent in March. MTN dominated this segment with 80.7 percent of subscriptions, reflecting a push by operators into home broadband and fixed wireless services.

The numbers reflect a deeper structural change. Monthly data usage has more than doubled since early 2023, when it stood at around 517,000 terabytes. Nigerians are consuming far more data per user, even as subscriber growth slows.

Streaming services, cloud applications, online learning, and social platforms now drive most traffic.

However, quantity does not always mean quality. Many users still complain about slow speeds and network congestion, especially during peak hours.

Mobile networks handle the vast majority of connections, while fixed broadband and ISP subscriptions remain relatively small.

Affordability continues to limit deeper adoption. High smartphone prices remain a barrier for low-income earners and people in rural areas.

Despite ongoing upgrades, Maida pointed out that user experience improvements are often quickly eroded by rising data consumption. As network performance improves, users consume more data, especially through high-bandwidth platforms like video streaming and social media, leading to renewed congestion.

This creates a cycle where network upgrades temporarily ease congestion but are rapidly overtaken by increased demand. He stressed that achieving lasting improvement will require building excess capacity, not just meeting current demand.

The NCC leadership expressed cautious satisfaction with current investment levels, highlighting that one major operator alone is investing over $1 billion this year, surpassing total industry spending in the previous year.
