After two decades, Nigeria’s 3G era is nearing its final call

Published 22 June 2026

MTN Group, the continent’s largest operator, plans to shut down some of its 3G networks before 2030 as telcos across Africa move customers to newer technologies such as 4G and 5G.

The move to shut down 3G networks is a significant development in the African telecoms sector, with implications for both telcos and their customers. On the one hand, it reflects the growing demand for faster and more reliable mobile internet services, which is driving investment in 4G and 5G infrastructure. On the other hand, it highlights the challenges of transitioning to newer technologies, particularly in rural areas where 3G coverage is often the only option available. As telcos navigate this transition, they will need to balance the need to upgrade their networks with the need to ensure that all users have access to reliable and affordable mobile internet services.

The economic implications of shutting down 3G networks are significant, with telcos facing costs associated with decommissioning their 3G infrastructure and transitioning customers to newer technologies. However, the benefits of upgrading to 4G and 5G are also substantial, with faster data speeds and greater capacity expected to drive growth in data revenues and support the development of new services such as:
* IoT (Internet of Things) applications
* Online gaming and video streaming
* Mobile payments and financial services
* E-commerce and online shopping

The transition to 4G and 5G is part of a broader trend towards greater digitalization and connectivity in Africa. As the continent's economies grow and become more integrated, the demand for faster and more reliable mobile internet services is expected to increase. This will drive investment in 4G and 5G infrastructure, as well as the development of new services and applications that take advantage of these technologies. As >
the Nigerian telecoms sector continues to evolve, it is likely that we will see significant innovations and investments in the digital space, with 4G and 5G technologies playing a critical role in driving growth and development.

As MTN Group and other telcos shut down their 3G networks, they will need to ensure that customers have access to alternative technologies, such as 4G or 5G. This will require significant investment in network infrastructure, as well as efforts to educate customers about the benefits of upgrading to newer technologies. As the transition to 4G and 5G accelerates, we can expect to see significant developments in the African telecoms sector, including the launch of new services and applications that take advantage of these technologies.

The shutdown of 3G networks in Nigeria marks a significant milestone in the country's transition to newer mobile technologies. As MTN Group and other telcos invest in 4G and 5G infrastructure, they will need to balance the need to upgrade their networks with the need to ensure that all users have access to reliable and affordable mobile internet services. As the African telecoms sector continues to evolve, it is likely that we will see significant innovations and investments in the digital space, with 4G and 5G technologies playing a critical role in driving growth and development. >
The future of mobile internet in Africa is likely to be shaped by the transition to 4G and 5G, and it will be important for telcos, policymakers, and other stakeholders to work together to ensure that all users have access to the benefits of these technologies.
