Africa’s economies increasingly run on digital rails. Mobile connectivity already contributes around 7% of Sub-Saharan Africa’s GDP, or about $140 billion in 2023, and the wider mobile ecosystem adds 5.8% to global GDP. Every incremental lift in broadband penetration has a measurable growth effect, with the World Bank estimating a 0.25% to 1.4% GDP boost for each 10-point increase in broadband access.
This dependence is deepening as mobile money becomes the everyday financial infrastructure. In 2024, the world processed roughly $1.68 trillion via mobile money, and Africa accounted for the majority of value and transactions. GSMA data shows Sub-Saharan Africa generated about two-thirds of merchant payments and added an estimated $190 billion to GDP through mobile money use in 2023. Disruption of telecoms therefore risks cascading shocks to payments, bills, remittances, and SME cash flow.
At the same time, availability is fragile. Subsea cables carry about 99% of intercontinental data traffic. When four cables failed off West Africa in March 2024, at least 10–13 countries suffered degraded or near-total outages. Similar disruptions hit East Africa in May 2024, and South Africa saw WACS issues in June 2025 that slowed national traffic. Regions with fewer alternate routes are particularly exposed.
Terrestrial networks face steady physical threats. South African operators still absorb heavy losses from base-station vandalism and battery theft. Industry reporting indicates combined costs for MTN and Vodacom of about R550 million in 2024, with Vodacom estimating around R100 million a year in some provinces and warning of direct impacts on emergency services and small businesses when sites go dark.
Cyber risk is rising fast. INTERPOL’s 2025 Africa Cyberthreat Assessment notes a sharp increase in cyber-related crime, with 10,490 cybercrime-related arrests reported by 19 countries in 2024. Large African operations in 2025 disrupted sextortion and online fraud rings across 14–19 countries, underscoring both scale and the need for coordinated response. South Africa’s digital-banking fraud losses surged to roughly R1.9 billion in 2024, with app-based attacks dominating.
Closing the resilience gap is urgent because the usage gap remains the world’s widest. In Sub-Saharan Africa, more than half of adults live within coverage but do not use mobile internet, often due to affordability and safety concerns. Building trust through robust security, anti-vandalism partnerships, SIM-swap prevention, and cable route redundancy is not a technical nicety. It is economic policy, social stability, and financial inclusion rolled into one.
Our call to action is to align operators, regulators, law enforcement, banks, and civil society on a common telecom-security blueprint that tackles physical sabotage, cybercrime, and infrastructure single points of failure, while sustaining inclusive access that drives growth.
