Mobile Money in Africa: How Phones Became Banks for Half a Billion People
The M-Pesa Breakthrough
In 2007, Kenya's Safaricom launched M-Pesa, a service that allowed users to send money via text message. No bank account was needed. No smartphone. No internet connection. A customer handed cash to an agent — often a corner shop — who credited their mobile wallet. They could then send that balance to any other phone number in Kenya, where the recipient could withdraw cash from another agent. The system worked because it solved a real problem: millions of Kenyans had mobile phones but no access to banking.
The growth was explosive. Within five years, M-Pesa was moving over 30 percent of Kenya's GDP through its network. It expanded into savings, loans, bill payments, and merchant transactions. The model spread across Africa: MTN Mobile Money, Airtel Money, Orange Money, and dozens of local services now serve over 500 million registered accounts across the continent. Mobile money has done more to expand financial inclusion in Africa than any government program or traditional bank.
The Nigerian Market
Nigeria is Africa's largest economy and its most complex mobile money market. Unlike Kenya, where M-Pesa achieved near-monopoly status, Nigeria has multiple competing services: MTN's MoMo, Airtel's SmartCash, OPay, PalmPay, and traditional banks that have built their own digital offerings. The market is younger, more urban, and more competitive.
MTN Nigeria's fintech revenue declined 7 percent in mid-2026, partly due to new Central Bank of Nigeria regulations on digital lending. The regulations targeted predatory lending practices — apps that charged exorbitant interest rates, harassed borrowers' contacts, and operated without licenses — but they also constrained legitimate operators. The balance between protecting consumers and enabling innovation is delicate, and Nigeria's regulators are still calibrating it.
The Regulatory Frontier
Mobile money regulation in Africa is a patchwork. Kenya's approach has been permissive, allowing Safaricom to dominate while the central bank eventually imposed interoperability requirements. Ghana has been more prescriptive, mandating interoperability from the start. Tanzania introduced a mobile money levy in 2021 that reduced transaction volumes. Nigeria oscillates between promotion and restriction, reflecting the tension between financial inclusion goals and concerns about fraud, data privacy, and market concentration.
The next frontier is cross-border mobile money. The African Continental Free Trade Area envisions a single market for goods and services, but sending money from a Kenyan M-Pesa wallet to a Nigerian MTN MoMo wallet remains difficult and expensive. Regional payment systems like the Pan-African Payment and Settlement System are designed to solve this, but implementation is slow. The prize is enormous: intra-African remittances and trade, settled instantly via mobile phones, without the currency conversion costs and delays of the correspondent banking system.
