When we talk about mobile data growth, the rapid increase in the amount of data transmitted over cellular networks worldwide. Also known as cellular data expansion, it is reshaping how people connect, stream, and work on the go.
One of the biggest forces behind this surge is internet bandwidth, the capacity of networks to carry data. Mobile data growth drives higher bandwidth demand, while greater bandwidth enables smoother video calls, e‑learning, and mobile commerce. In other words, internet bandwidth and mobile data growth feed each other in a virtuous cycle.
The rollout of 5G networks, the fifth generation of cellular technology offering ultra‑fast speeds and low latency is a game‑changer. 5G not only multiplies the speed of data transfer but also lowers the cost per gigabyte, making massive data files feel like light breezes. This means that mobile data growth now requires expanding 5G coverage, and in turn, 5G thrives on the appetite for more data.
Alongside 5G, the legacy 4G LTE, fourth‑generation long‑term evolution technology that still powers most current mobile traffic remains a backbone in many African markets. While 5G opens new frontiers, 4G LTE keeps the data tide flowing, ensuring that mobile data growth does not stall in regions where 5G is still rolling out.
Data consumption patterns have evolved dramatically. Data consumption, the amount of data users download or upload daily now includes high‑definition video streaming, cloud gaming, and real‑time collaboration tools. A single hour of HD video can drain several gigabytes, pushing carriers to upgrade their core networks. Mobile data growth therefore requires better data management practices, such as dynamic throttling and tiered data plans.
What fuels that hunger? smartphone adoption, the rate at which people acquire and use smartphones across the continent. More affordable devices, bundled data offers, and localized apps make it easier for first‑time users to go online. As smartphone adoption climbs, each new user adds to the cumulative data load, reinforcing the mobile data growth loop.
Mobile network operators (MNOs) are responding with innovative pricing models, data‑only SIMs, and edge‑computing services. These strategies aim to balance the cost of expanding infrastructure with the revenue from higher data usage. Regulatory bodies also play a role, setting spectrum auction rules that determine how quickly 5G can be deployed and how much bandwidth is allocated for public use.
All these elements—bandwidth, 5G, 4G LTE, data consumption, smartphone adoption, and operator strategy—intersect to paint a vivid picture of mobile data growth in Africa today. Below you’ll find a curated list of articles that dig deeper into each of these topics, offering practical insights, real‑world case studies, and forecasts that can help you stay ahead of the curve.
Telkom SA SOC Limited posted a 1.1% rise in revenue to R10.8 billion for the quarter ended June 30, 2025, while EBITDA jumped 6.5% to R2.8 billion. Mobile data subscribers grew 27.5% and fibre‑connected homes increased 17.5%, pushing data revenue to almost 60% of total sales. The EBITDA margin expanded to 25.9% thanks to cost efficiencies. CEO Serame Taukobong credited the data‑led strategy as the core competitive edge. The firm projects continued profit growth through disciplined execution.
