4G Remains Key Driver of Internet Adoption in Africa

Despite the growing rollout of 5G networks across the continent, data from Nigeria, South Africa, Kenya, Ghana, and Egypt reveals that 4G technology continues to be the primary driver of internet adoption. While 5G usage is expanding, particularly in urban areas, a significant portion of the population still relies on 4G for connectivity.

Key Findings Across Top African Markets:

Kenya: With 62 million internet users (79.1% of telecom subscribers), Kenya demonstrates high internet penetration fueled by both 4G and 5G networks. As of December 2025, 4G accounted for 63.1% of connections while 5G represented only 2.4%. However, 4G/5G jointly powered 93.4% of all data consumption.

Ghana: Currently in a transition phase, Ghana’s internet users are primarily split between 3G and 4G networks. The government launched 5G in March with the ambitious goal of achieving 70% population coverage by 2027 (the country’s 70th Independence Anniversary). As of 2025, 74.6% of Ghanaians had internet access.

Nigeria: 4G and 5G combined hold a 59% market share, surpassing legacy 2G/3G technologies. Since mid-2024, there’s been an inverse relationship between 2G and 4G usage, with 4G now accounting for 53.59% of connections (as of February 2026). While 5G adoption remains limited at 5.06%, initiatives like Project Bridge aim to boost coverage.

South Africa: Leading the continent in 5G availability, South Africa recorded 58% coverage in 2025 (up from 46.6% in 2024). The country consistently ranks high for both 5G speed and accessibility, with a smartphone penetration rate of 70.8%. Government plans to phase out 2G/3G networks will further accelerate the transition to newer technologies.

Implications for African IT Leaders:

The sustained dominance of 4G underscores the importance of investing in both existing infrastructure and emerging network technologies. For IT leaders, this means:

  • Prioritizing 4G upgrades and expansions to serve current user needs
  • Strategically deploying 5G where it offers clear advantages (e.g., fixed wireless access, industrial applications)
  • Developing hybrid solutions that leverage both 4G and 5G capabilities
  • Addressing the digital divide by ensuring affordable access across all regions
