Africa’s Data Use Is Surging - What That Means for Networks, Prices and Consumers

Africans are using more mobile data for video, social media, payments, work and increasingly AI-powered services. That growth is good news for the digital economy—but it also puts pressure on networks, infrastructure investment and household budgets.

Africa is not simply adding more internet users. People who are already connected are also using considerably more data. Ericsson’s latest Mobility Report regional figures estimate that mobile data traffic in Sub-Saharan Africa reached about 2.8 exabytes per month in 2025 and could rise to 9.7 exabytes per month by 2031.

Average traffic per active smartphone is projected to increase from 5.3GB to 12GB per month over the same period. That growth creates an opportunity for operators—but it also means African networks have to carry much more traffic without allowing slower speeds, congestion or higher costs to undermine the experience.

Nigeria shows how quickly usage can change

Nigeria provides a particularly clear example. The Nigerian Communications Commission’s industry statistics show internet data usage rising from about 1.04 million terabytes in May 2025 to 1.50 million terabytes in May 2026. That is an increase of roughly 44% in one year.

At the same time, Nigeria’s network mix continues to move towards faster technology. NCC figures for May 2026 show 4G accounting for about 54.3% of mobile subscriptions by technology generation, while 5G had risen to approximately 4.5%.

Faster networks do not inherently consume data for no reason. But when connections improve, people can comfortably do things that were frustrating on slower networks: stream higher-quality video, make video calls, download large applications, back up photographs and use cloud-based services. That changes consumption behaviour.

Video is turning smartphones into heavy data devices

One major driver is obvious every time someone opens TikTok, YouTube, Instagram or another video heavy platform. The internet has become increasingly visual. Social feeds automatically load clips. Streaming platforms offer higher resolutions. Messaging apps exchange videos and large media files. Operating systems and applications regularly download updates in the background. Even everyday behaviour can therefore consume several gigabytes without users consciously downloading a large file.

The NCC’s consumer guidance on data usage notes that consumption varies according to factors including network technology, device specifications, websites and services used, and background software activity. This is why two people with similar phones and the same data bundle can have very different experiences.

Networks now have to grow faster than the traffic

Higher consumption is useful to telecom operators only if their networks can handle it. A base station serving thousands of users has finite radio and backhaul capacity. If demand grows much faster than capacity, customers may experience slower speeds particularly during busy periods, and traffic is not evenly distributed.

Ericsson warns in its mobile traffic outlook that regional averages cannot simply predict congestion in individual locations. Traffic demand in dense urban areas can be dramatically higher than in rural ones. Operators therefore need more than headline 5G launches.

They need additional fibre, spectrum, upgraded radio equipment, better backhaul, reliable power and more sites in areas where demand is concentrated. The GSMA estimates African mobile operators will invest more than $76 billion in network infrastructure between 2024 and 2030, according to its Mobile Economy Africa 2026 findings. Consumers should ultimately expect that investment to translate into better capacity and service not merely faster speed-test numbers.

Does using more data mean prices should fall?

Not necessarily. There is an intuitive argument that selling more data should allow operators to offer cheaper bundles. Greater usage can certainly improve the economics of networks. But data pricing also reflects electricity, spectrum, fibre, equipment, taxes, currency movements, maintenance and the cost of continually expanding network capacity.

Nigeria demonstrated this tension in 2025 when the NCC approved operator tariff adjustments of up to 50%, after noting that telecom tariffs had remained largely unchanged for years while operators faced rising costs. The regulator said the increases should also be accompanied by tangible improvements in service quality. So rising consumption does not automatically translate into lower consumer prices.

The more important question is whether the cost of useful connectivity becomes more affordable relative to incomes, that remains a serious issue. The GSMA’s 2026 Africa report identifies affordability as the largest single barrier preventing many people who already live within mobile-broadband coverage from actually using mobile internet.

5G will accelerate the pressure

Sub-Saharan Africa is still relatively early in its 5G transition. Ericsson forecasts that regional 5G subscriptions could rise from around 30 million in 2025 to 370 million by 2031. More 5G does not automatically mean everyone will suddenly consume huge amounts of data. Device prices, coverage and bundle affordability still matter.

But 5G makes heavier applications more practical, including fixed wireless broadband, high-resolution streaming, cloud services and emerging AI applications. That means the network conversation is shifting. The challenge is no longer only “Can people get a signal?” It is increasingly “Can the network deliver enough capacity at a price people can afford?”

What consumers should watch

For users, headline data volumes tell only part of the story. A genuinely improving market should bring better speeds during busy periods, fewer unexplained outages, clearer bundle pricing and stronger coverage—not simply larger bundles that disappear quickly because applications are becoming more data-intensive.

Consumers should also continue checking which apps use the most background data, limiting automatic video quality where necessary and controlling large software or cloud-backup downloads. Those steps will not solve affordability problems, but they can stop unnecessary background consumption from making an expensive connection even more expensive.

Our Recommendation

Africa’s rising data consumption is a sign of a digital economy becoming more active. People are streaming, communicating, banking, learning, working and running businesses through their phones at a scale that networks built around lighter usage increasingly have to accommodate.

That should encourage investment. But success should not be measured only by how many exabytes Africans consume or how many 5G towers operators activate. The real test is whether networks can carry that growing demand while keeping connectivity reliable and affordable for the people paying for it.

If data use keeps accelerating while network investment and affordability fall behind, consumers will simply experience more congestion and higher bills. If infrastructure keeps pace, Africa’s data surge could instead become one of the foundations of its wider digital economy.
