Kenya's 5G subscribers account for just 3% of the country's mobile data users, yet new regulator data shows they are consuming a strikingly outsized share of its internet traffic.

Industry figures from the Communications Authority of Kenya (CAK) show that 5G accounted for 2.10 million subscriptions out of 64.26 million total mobile data connections as of June 2026, or about 3.27% of all data users in the East African nation. 4G remains dominant with 48.31 million users, equivalent to roughly 75% of the market. The figures appear in the regulator's Sector Statistics Report.

The numbers come at a time when Kenya's 5G rollout trails that of most African countries. The gap has been attributed to coverage limitations, inadequate funding, vandalism, frequent network outages, and the cost of 5G-enabled devices. Although 5G devices are becoming more affordable, limited network availability and coverage continue to constrain the experience for users. With roughly three-quarters of data users still on 4G, the pace of coverage expansion and device affordability will shape how much of the country's rising data demand shifts onto 5G.

Kenya is not an outlier. Across Africa's leading markets by data consumption, network development, and economic strength, 5G's share of internet users remains small. In Nigeria, industry data shows that only 4.74% of the country's 195.1 million telecom subscribers were on the network as of July 2026, according to the Nigerian Communications Commission (NCC). Commercial rollout is expanding across several African markets, though deployment remains uneven — Ghana, for example, is still working through a competitive 5G spectrum licensing process.

At the same time, demand for high-speed connectivity keeps climbing. Individual subscribers, businesses, and enterprises are seeking faster data to power financial services, retail, manufacturing, and logistics, using 5G to handle data-intensive operations, cloud services, and digital payments. The pattern underscores how demand for internet speed has continued to outpace its supply.

Small base, heavy consumption

Despite representing only about 3.3% of Kenyan users, 5G generated 135.38 million gigabytes (GB) of traffic in the second quarter of 2026 alone, up from 43.86 million GB in the same quarter of 2025 — a 208% year-on-year increase, according to the CAK data.

Usage per subscriber tells a similar story. An average 5G subscriber consumes about 64.4 GB per month, compared with 15.8 GB on 4G and 8.3 GB on 3G. In other words, 5G users consume more than four times as much data as the average 4G user.

The drivers are familiar. Adoption is concentrated among heavy data users and enterprise customers, aided by the network's speed. The devices that connect to it — flagship smartphones, routers, and Fixed Wireless Access units — remain premium products, and their owners typically engage in high-bandwidth activities such as 4K and 8K video streaming, cloud gaming, and automated background downloads.

Higher bandwidth also changes app behavior: applications default to higher-resolution media, from HD video to uncompressed social media feeds. And because users can download files or stream content more quickly, overall consumption rises naturally within the same amount of session time.

For telecom operators, the trend is a revenue tailwind. High-volume consumption translates directly into larger data bundle purchases, making 5G subscribers the most profitable segment per line.

Nigeria's consumption surge

Nigeria offers a comparable picture. While the NCC does not publish statistics breaking down data consumption by network type, available figures show a significant rise in overall internet usage. Nigerians consumed 1.38 million terabytes of data in January 2026, up from 1 million terabytes in January 2025 — an increase attributed largely to 5G network expansion and the adoption of compatible devices. By July 2026, monthly data usage had reached a record 1.67 million terabytes, with consumption expected to cross 2 million terabytes before the end of 2026.

The growth comes as leading operators MTN and Airtel Nigeria actively expand their 5G infrastructure and mast deployments across the country's major urban centres. Both have announced plans to double their 5G sites in key cities, including deploying small-cell solutions and mini-antennas in high-traffic zones to support surging demand.

That build-out is costly. In the first half of 2026, MTN reportedly spent ₦620.5 billion on capital expenditure, while Airtel said it spent ₦287.6 billion ($211 million) on 4G/5G tower deployment and related investments. In both markets, upcoming regulator releases — the CAK's sector statistics and the NCC's industry data — will show whether 5G's subscriber share starts to catch up with the outsized consumption its users already generate.

Why 5G "burns" data faster

The popular perception that 5G consumes data faster is, in structural terms, accurate. Faster speeds remove the throttling bottleneck that once slowed transfers, allowing devices and applications to pull maximum data quality with little effort — and pushing per-user consumption steadily higher.
