- DRC Becomes Launchpad for Airtel-Starlink Direct-to-Cell Push Across Africa
Airtel Africa and Elon Musk’s SpaceX are moving satellite connectivity directly onto ordinary mobile phones in the Democratic Republic of Congo, marking a potentially important shift in how telecommunications operators tackle some of Africa’s most persistent mobile-coverage gaps.
The service uses Starlink’s Direct-to-Cell technology to allow compatible smartphones to connect directly with low-Earth-orbit satellites in locations where conventional terrestrial mobile networks are unavailable. It builds on an Airtel-SpaceX agreement covering all 14 of Airtel Africa’s markets and a customer base of about 174 million.
The technology is significant because it attempts to remove one of the traditional barriers to satellite connectivity: specialised consumer equipment.
Rather than requiring households to install a Starlink dish or carry a dedicated satellite phone, Direct-to-Cell is designed to allow compatible conventional smartphones to connect when terrestrial coverage disappears.
That could materially change the economics of extending connectivity into remote parts of Africa.
Mobile operators have traditionally expanded coverage by building towers connected through fibre, microwave links or other terrestrial infrastructure. That model works well in densely populated areas where thousands of customers can share the cost of a site.
It becomes considerably more difficult in sparsely populated communities, forests, mountainous regions and other areas where the capital required to build and maintain a tower may be difficult to justify commercially.
Satellite connectivity offers another option. Instead of attempting to place physical infrastructure within every difficult-to-reach community, low-Earth-orbit satellites can effectively extend the mobile network from space.
Airtel Africa has previously said Starlink’s technology complements its terrestrial infrastructure and is particularly useful in areas where conventional network deployment is challenging.
That makes the DRC an especially relevant market. Its vast geography and difficult terrain make universal terrestrial coverage expensive, creating precisely the sort of connectivity gaps that satellite-to-phone technology is designed to address.
But the initial service should not be confused with conventional high-speed mobile broadband. Airtel’s wider Direct-to-Cell rollout is beginning with text messaging and data for selected applications, rather than attempting immediately to replicate the full capacity of a terrestrial 4G or 5G network.
Earlier testing in Kenya demonstrated that ordinary 4G-compatible smartphones could connect to Starlink satellites in locations with no terrestrial signal and use lighter-data services including messaging, maps, WhatsApp calling and Airtel financial transactions.
That distinction matters. The immediate economic value of satellite-to-phone connectivity is less about allowing rural consumers to stream high-definition video and more about ensuring that basic digital services remain available where there was previously no network at all.
A text message, mobile-money transaction, navigation service or emergency communication can have disproportionately large value when the alternative is complete disconnection.
For African economies, that could have consequences beyond telecommunications.
Farmers operating in remote communities increasingly rely on mobile phones for market prices and payments. Small businesses need connectivity to transact through mobile money. Health workers require communication networks, while governments increasingly deliver information and services digitally.
Connecting previously uncovered locations therefore potentially brings households into financial and commercial networks as well as the telecommunications system.
The importance becomes clearer when considered against Africa’s mobile-first development model. For millions of people, the smartphone is not simply a communications device. It is a bank branch, payment terminal, marketplace, classroom and source of public information.
Extending network availability therefore expands the infrastructure through which other parts of the digital economy operate.
The commercial implications for Airtel are equally important. Satellite technology could allow the operator to expand the geographic footprint of its service without replicating the full cost structure of terrestrial coverage in every marginal location.
That does not mean satellites will replace towers. Dense urban centres and high-traffic areas will continue to require fibre-connected terrestrial networks capable of carrying enormous volumes of data at low latency.
The more plausible model is hybrid. Terrestrial networks would carry the majority of traffic, while satellite connectivity fills coverage gaps and provides an additional layer of resilience.
Research into direct-to-device satellite systems similarly describes the technology principally as an extension of existing mobile networks in underserved areas rather than an immediate replacement for conventional cellular infrastructure.
For Airtel, that potentially alters the economics of universal coverage. Historically, the last percentage points of population or geographic coverage can be the most expensive because remaining communities are often dispersed and difficult to reach. Satellite-to-phone systems could reduce the need to construct uneconomic sites solely to achieve basic coverage.
But they introduce different costs. Airtel and other operators will still need spectrum arrangements, regulatory approval, integration with terrestrial networks and commercial agreements with satellite providers. Customers must also use compatible devices.
Capacity represents another constraint. A satellite beam serves a large geographical area and cannot currently provide the same concentrated bandwidth as thousands of terrestrial radio sites operating across a populous city.
That is why the technology’s early African use case is focused on lighter applications.
SpaceX and Airtel have said future generations of Direct-to-Cell satellites are expected to provide substantially higher data capacity, potentially increasing speeds by as much as 20 times compared with the initial system.
If those improvements materialise, the competitive implications could become much larger. Satellite operators would move progressively closer to the core market of conventional mobile companies rather than simply serving the fringes of their networks.
For now, however, Airtel has chosen partnership rather than confrontation. That model may become increasingly common across Africa.
Mobile operators possess spectrum licences, millions of customers, billing systems, retail networks and local regulatory relationships. Satellite companies possess infrastructure capable of extending coverage across enormous territories.
Combining the two can be more commercially effective than attempting to build competing ecosystems. Airtel’s agreement with SpaceX aims eventually to introduce the technology across all 14 of its African markets, subject to individual national regulatory approvals.
That makes the DRC deployment potentially more important than a single-country launch. It could serve as an early commercial test of whether direct-to-cell satellite connectivity can work at scale in African conditions.
If successful, the model could spread across markets including Nigeria, Kenya, Zambia, Malawi, Rwanda, Niger, Chad and Madagascar, where Airtel already operates and Starlink has obtained relevant market access for its broader services.
The regulatory dimension will nevertheless be critical. Satellites transmitting directly to ordinary phones interact with spectrum historically assigned to terrestrial mobile operators. Governments must determine how those frequencies are used, how interference is prevented and what obligations apply to foreign satellite infrastructure providing domestic telecommunications services.
Data governance and national security considerations are likely to remain part of that debate. The emergence of satellite-to-phone connectivity also introduces another layer of competition into Africa’s telecom industry.
Tower companies, mobile operators and fibre providers have spent billions building terrestrial infrastructure across the continent. Low-Earth-orbit satellites do not eliminate the need for those investments, but they could alter where the next dollar of network capital is most efficiently deployed.
Rather than building an expensive tower to serve a relatively small remote population, an operator may increasingly decide that satellite coverage provides sufficient service while terrestrial investment is concentrated in higher-demand areas. That could make network expansion more capital-efficient.
The larger question is affordability. A technology capable of reaching remote communities will have limited developmental impact if the people living there cannot afford to use it.
The eventual pricing of Airtel’s satellite-enabled services will therefore be as important as the technology itself.
Africa’s connectivity challenge has never been solely about whether a signal exists. Device costs, data affordability, digital skills and household incomes all determine whether available networks are actually used.
Direct-to-Cell solves only one part of that equation. For decades, reaching the final pockets of Africa’s population with mobile infrastructure has required operators to push physical networks deeper into increasingly difficult and commercially marginal territory.
Starlink changes the geometry. The mobile tower can now, effectively, be hundreds of kilometres above the earth.
If the DRC rollout demonstrates that ordinary smartphones can switch successfully between terrestrial and satellite connectivity at commercially viable costs, the implications could extend across the continent.
Airtel’s next network expansion may therefore not be measured only by how many towers it builds. Increasingly, it could also be measured by how much of Africa it can cover without building a tower at all.
