In a groundbreaking trial, MTN South Africa and Lynk Global completed Africa’s first satellite-to-smartphone voice call on March 27 in Vryburg. This was achieved using a standard mobile device connected to a low-Earth orbit (LEO) satellite.
Approved by South Africa’s communications regulator, this historic connection represents a significant step toward addressing the rural digital divide, particularly in underserved areas where establishing mobile infrastructure is expensive. With 96% of South African households relying on cellphones and many rural users facing coverage gaps, the trial holds promise for future satellite-based connectivity. While satellite technology isn’t a complete solution, it could greatly enhance access for millions who are currently disconnected.
The trial signifies a major advancement for African telecom providers like MTN, showcasing the potential of LEO satellites to support existing terrestrial networks. It also aligns with MTN’s goal of expanding broadband coverage across South Africa, moving closer to its target of 99% coverage. The unique attributes of LEO constellations, such as their lower altitudes and rapid orbital cycles, facilitate faster and nearly real-time data communication with reduced latency, benefiting applications like video conferencing and online gaming. An important advantage of this technology is its compatibility with standard mobile devices, which is crucial in Africa, where mobile usage is widespread but access to advanced devices is limited due to cost.
Additionally, direct satellite-to-phone connectivity could enable the development of mass notification systems for critical alerts, including weather warnings and health advisories. The trial took place in Vryburg, an agricultural town in the North West Province, following the Independent Communication Authority of South Africa’s (ICASA) approval of radio frequencies on MTN-licensed IMT spectrum.

In 2023, Lynk Global also signed a contract with Telecel Group to provide satellite-based connectivity to Vodafone Ghana subscribers. That same year, Vodacom, South Africa’s largest operator, partnered with Amazon’s Project Kuiper to enhance its connectivity solutions using LEO satellites. Starlink, a major player in Africa’s satellite connectivity landscape, conducted its first Direct-to-Cell technology test in the U.S., allowing standard mobile phones to connect directly to satellites, though it has yet to announce availability in Africa. The potential entry of Starlink could intensify competition among telecom providers, driving improvements in connectivity across the continent.
