Nigeria’s Data Boom comes with a growing infrastructure costs

Nigeria's surge in mobile internet usage has given rise to a critical infrastructure problem: the need for more network capacity and maintenance. The Nigerian Communications Commission (NCC) recorded a record 1.66 million terabytes (TB) of data consumption in July 2026, up from 1.53 million TB in June and 1.50 million TB in May. Between January and July 2026, Nigerians consumed about 10.18 million TB of data, compared to 5.9 million TB in the same period of 2025.

This data boom necessitates continuous expansion of network capacity, deployment of additional fiber, equipment upgrades, increased coverage, and maintenance of existing infrastructure. Who finances this expansion and how sustainable it becomes as Nigeria's digital economy grows is the key question.

MTN Nigeria, for instance, invested N1 trillion in network capacity in 2025, double the amount invested in 2024. This investment reflects the direct relationship between data consumption and capacity – as users engage in high-bandwidth services, operators must invest in networks capable of handling that traffic. The company has also expanded its fixed broadband business through fibre-to-the-home (FTTH) and fixed wireless access, with a new data centre in Lagos and a $240 million commitment for the data centre project, $120 million of which is already spent.

The NCC's latest data shows the expanding footprint of FTTH services, with 319,735 total FTTH subscriptions in Q2 2026, 176,468 of which are with MTN. However, maintaining these networks becomes costly when existing assets are damaged. The NCC noted over 5,000 fibre-optic cable cuts in the first half of 2026 due to road construction, excavation, and other civil works. These damages can lead to failed calls, blocked payments, interrupted services, and lost economic opportunities.

The impact goes beyond telecom companies, as the Nigeria Inter-Bank Settlement System (NIBSS) reported a 79.03% increase in Point of Sale (PoS) transactions to N18.78 trillion in Q1 2026, highlighting how crucial connectivity is to commercial activities. A network disruption can affect businesses and individuals alike, from merchants receiving payments to consumers browsing the internet.

Telecommunications infrastructure investment primarily comes from private-sector operators who reinvest revenues into network expansion and maintenance. However, this environment is heavily impacted by factors beyond data consumption, such as the cost of repairing damaged infrastructure or the need for additional capacity when demand rises sharply.

This continuous cycle of more users requiring more capacity, more capacity requiring more capital, and a larger infrastructure footprint necessitating more maintenance and protection creates an infrastructure economy of its own.
