Intra-African Roaming Costs: The Hidden Tax on Africa’s Digital Economy

Africa has spent two decades building infrastructure for a connected continent. Subsea cables land on its coasts, mobile towers dot its landscapes, and regional free trade agreements bind its economies in law. Yet the moment a professional crosses a border with a phone in their pocket, the cost of staying connected can multiply tenfold overnight. A gigabyte of data that costs $1 at home routinely costs $10 to $15 on international roaming. The networks are there. The policy framework to make them work affordably across borders is not, and the gap between those two realities is costing the continent more than most economic analyses have been willing to quantify.

Africa’s intra-regional roaming market is currently valued at $2.82 billion  and is on track to reach $3.81 billion by 2030. That figure is often read as a sign of commercial vitality. It is more accurately read as a measure of the premium being extracted from the continent’s most mobile and economically active people, in a market where affordable alternatives simply do not exist at scale.

In this TechTalk Thursday, we explore how intra-African roaming charges continue to quietly tax Africa’s digital economy despite growing connectivity across the continent.

A tax on productivity

Africa’s mobile sector contributed $220 billion to continental GDP in 2024 , equivalent to 7.7% of total economic output, with more than $120 billion of that coming directly from productivity effects. Mobile connectivity is not peripheral to Africa’s growth story. It is the mechanism through which much of that growth is being delivered, from mobile payments and supply chain coordination to cross-border commerce and digital services. The roaming constraint sits directly inside that mechanism.

The problem is sharpest for the users who matter most to economic output. Consider what the data shows about who is actually crossing borders with a phone:

• Enterprise roamers consume an average of 2.5GB of data per trip , compared to 0.8GB for leisure travelers.

• Business travelers and professionals moving between markets are the heaviest data consumers when they cross borders, and they face the steepest cost penalty for doing so.

• When connectivity at that level is priced at roaming rates, the result is a direct tax on cross-border economic activity, levied not by governments through formal policy but by a fragmented pricing system that no one has yet been required to fix.

The affordability context matters here. In 2024, a basic 2GB mobile data plan already cost the equivalent of 3.9% of average monthly income in Sub-Saharan Africa, the highest affordability burden anywhere in the world according to the ITU. That is the baseline. The moment a subscriber crosses a border, they are paying multiples of a baseline that is already the world’s least affordable.

“I think the biggest one is fiscal policy because that affects the affordability of both devices and data.”

-Angela Wamola, Head of Africa, GSMA

Despite mobile broadband coverage reaching the majority of the continent, 710 million Africans who live within signal range still do not use the internet. Roaming costs are not the only driver of that gap, but for the segment of the population that moves across borders regularly, they are one of the most direct ones.

Why the pricing structure persists

Africa’s roaming market is built on bilateral interoperator tariff agreements, negotiated individually between carriers across 54 different national regulatory environments. These agreements set the wholesale rates that operators charge each other for carrying cross-border traffic, and those costs flow downstream to consumers with markup applied at each stage. There is no continental reference rate, no enforceable ceiling, and no standardised transparency requirement.

National policy divergence compounds the problem at every level: In early 2025, Nigeria permitted domestic tariff increases of up to 50%, while neighbouring markets maintained entirely different regulatory structures. Operators running pan-African networks must maintain parallel billing architectures to remain compliant across jurisdictions, raising operational costs and eliminating most of the commercial incentive to simplify pricing at continental scale.

“All stakeholders, including the private sector, governments, investors, and UN agencies, must come together to create partnerships that can drive sustainable digital transformation with a multiplying effect across all sectors.”

– Dr. Emmanuel Manasseh, Regional Director for Africa,  International Telecommunication Union (ITU)

“One of the areas we highlight is that nation-states need to be very thoughtful about developing national digital strategies. From there, they must consider fiscal policies for the digital sector, including taxation, pricing frameworks, and related measures. There is still significant work to be done in this area.”

– Ralph Mupita, President and CEO, MTN Group

The technical barriers that remain, particularly around spectrum interoperability for lower-cost handsets, mean that in several markets the infrastructure itself routes roaming traffic through more expensive pathways, building cost into the system before pricing decisions are even made.

Domestic data prices have fallen steadily over the past five years across most African markets. Cross-border pricing has not followed. That divergence is not a market failure in the conventional sense. It is the predictable outcome of a regulatory environment that has never required it to change.

The AfCFTA contradiction

The legal dimension of this problem deserves more attention than it typically receives. Under Annex 7 of the AfCFTA Digital Trade Protocol, all 54 signatory states have committed to non-discriminatory treatment for cross-border digital services. A roaming pricing regime in which a visiting subscriber pays 10 to 15 times more per gigabyte than a local user on the same physical network is, on its face, discriminatory treatment of a cross-border digital service. The protocol is in force. The pricing practice it implicitly prohibits is also in force, across the same continent, simultaneously.

Africa’s e-commerce market is projected to reach $712 billion by 2050. The cross-border digital participation required to realise that projection depends on affordable, reliable connectivity for people and businesses moving between markets. Roaming costs in their current form are a structural barrier to that participation, operating at the exact intersection of trade, mobility, and digital commerce that AfCFTA was designed to liberalise.

“Harmonization across different countries is essential and will naturally happen through the implementation of binding protocols under the AfCFTA. This will ensure that every trader can thrive in this market, facilitating seamless trade for a market of 1.4 billion people.”

— Jean Pascal Mvondo, Regional Lead for Francophone Africa and the Middle East, UN Better Than Cash Alliance

The proof of concept already exists

The most instructive aspect of this debate is that the solution has already been demonstrated, repeatedly, at regional scale. Three cases make the argument clearly:

East African Community One Area Network: The framework reduced cross-border roaming costs between member states and produced measurable increases in data usage without triggering operator revenue collapse. Volume increased, and the commercial model adjusted.

SADC Roaming Mandate: The SADC mandated a 94% reduction in roaming costs across its member states. The major operators, including MTN, Vodacom, and Airtel, complied when it was required of them. The networks did not destabilise. The economics remained viable.

Ghana-Togo-Benin Free Roaming Corridor: Formally launched in October 2024 , cross-border traffic volumes on the corridor tripled within 18 months of implementation, even as wholesale revenue per unit declined. In September 2025,  ECOWAS adopted a bloc-wide wholesale roaming tariff cap of $0.015 per megabyte across all 15 member states, institutionalising that benchmark across West Africa’s entire regulatory framework.

The pattern across every market where reform has been implemented is consistent. Lower prices generate volume growth that offsets the per-unit revenue reduction, and the network economics remain viable. The gap between those markets and the rest of the continent is not explained by infrastructure readiness or technical complexity. It is explained by whether regulators have been required to act in the regional public interest rather than the narrower interests of domestic operator revenue protection.

What continental reform would look like

Africa has the institutional architecture for a continental solution. The AfCFTA Digital Trade Protocol provides the legal foundation. The EAC, SADC, and ECOWAS precedents provide an operational template stress-tested across different market structures and regulatory environments. Three specific interventions would move the dial:

A Roam Like Local framework for high-volume corridors. Built on the ECOWAS-tested benchmark of $0.015 per megabyte, this would immediately lower the cost of cross-border digital participation where trade flows are already most concentrated, delivering impact at the points of maximum economic leverage.

Standardised prepaid roaming bundles across all AfCFTA member states. Replacing the current system of opaque bilateral pricing with transparent, publicly comparable reference rates anchored to market realities rather than negotiating power asymmetries. This removes the structural opacity that currently allows high-margin corridors to persist unchallenged.

A reinvestment mechanism for non-compliant operators. Channelling a defined portion of revenues from operators outside the framework into a continental digital infrastructure fund, ensuring enforcement generates productive outcomes rather than simply functioning as a deterrent.

The modelled outcomes from those interventions, projected against results already observed in regional pilots, point to a 60% increase in cross-border data usage, 15 million new cross-border SME relationships, and a $1.2 billion annual gain in digital GDP. That is not a theoretical projection built on optimistic assumptions. It is an extrapolation from outcomes already observed in markets where the policy conditions were put in place.

The barrier that remains

Africa has completed the hardest stages of building a connected continent. The physical infrastructure is largely in place. The legal framework for integration has been signed. The regional proof of concept for affordable cross-border connectivity has been established in multiple corridors. What has not yet happened is the translation of those elements into a unified, enforceable continental standard that applies the same logic across all 54 markets simultaneously.

Roaming costs are no longer a technical problem. They are a governance problem, and the cost of leaving them unsolved, measured in lost productivity, suppressed digital trade, and a $1.2 billion annual drag on digital GDP, is a cost Africa is choosing to absorb while the infrastructure to eliminate it already exists. That is the hidden tax. And unlike most taxes, this one has a straightforward repeal mechanism, if the political will to use it can be found.
