The report noted that while the consensus remains that a widespread 5G rollout is more of a long-term prospect in Sub-Saharan Africa, there is a strong case to utilise the technology in some scenarios to serve certain connectivity requirements for individuals and enterprises.
Although 3G will remain the dominant connectivity technology in Sub-Saharan Africa, accounting for over half of total connections by 2025, this year marks a turning point as 3G adoption begins to decline for the first time.
According to the report, this reflects the growing shift towards 4G as operators take steps to migrate customers from legacy networks (2G and 3G).

“By 2025, 4G will account for a third of mobile connections in the region, compared to under a fifth of connections in 2021,” the report noted.

Mobile subscriptions grow
The GSMA report also revealed that mobile subscriptions have continued to grow.
According to the report, 515 million people had subscribed to mobile services in Sub-saharan Africa by the end of 2021, representing 46 per cent of the population. This was an increase of almost 20 million from 2020.

Further, the report noted that there will be nearly 100 million new subscribers by 2025, taking the total number of subscribers to 613 million (50% of the region’s population).
The two most populated countries – Nigeria and Ethiopia — will account for almost a third of new subscribers in the period to 2025.
“Sub-Saharan Africa’s demography, with a sizeable proportion of the population under the age of 18, means that subscriber growth will remain strong for the foreseeable future as young consumers move into adulthood and are able to subscribe to mobile services,” GSMA added.
Further, the report noted that young subscribers are more likely to be tech-savvy and keen on adopting mobile internet services, particularly more advanced 4G and, where available, 5G services.
“This is one trend to watch, given the implications for high-speed connectivity and the creation and distribution of digital services in the region.”
In a related story, the Exchange Africa recently revealed that by the end of 2021, 5.3 billion people had subscribed to mobile services, representing 67 per cent of the global population.
The report indicated that there will be an additional 400 million new mobile subscribers by 2025, most of whom will be from frontier markets in the Asia Pacific and Sub-Saharan Africa.
This will take the total number of subscribers to 5.7 billion representing 70 per cent of the world’s population.
According to GSMA’s Mobile Economy Report Series, mobile technologies and services generated $4.5 trillion of economic value in 2021.
Further, the report revealed the countries with the highest number of mobile subscribers. Below are the top four:
