Namibian Genius Who Invented a Mobile Phone That Works Without a SIM Card or Airtime Still Struggles to Find a Job as His Invention Remains Unproduced
A young Namibian innovator who designed a mobile phone capable of making calls without a SIM card, airtime, or mobile data is still struggling to secure employment years after his breakthrough invention captured international attention.
Simon Petrus, from northern Namibia, developed the unconventional mobile device while he was still a student, using recycled electronic components and basic engineering principles.
Unlike conventional smartphones that rely on cellular networks, Petrus’ phone operates using radio frequencies, allowing it to make direct calls to other compatible devices without the need for telecom infrastructure.
The prototype was assembled from parts salvaged from an old landline telephone, a television set, and a two-way radio system. By integrating these components, Petrus created a handheld communication device that functions independently of mobile network operators. The phone requires no SIM card, no airtime, and no data plan, making it potentially useful in remote or underserved areas with little or no cellular coverage.
Beyond its core calling function, the device includes several additional features, such as a small built-in television, an LED light, a cooling fan, and USB charging ports. All components are powered through a self-assembled circuit connected to a simple radiator-based power system.
Petrus first drew national attention after presenting the invention at a school science fair, where he won first prize. Images of the teenager showcasing a SIM-free phone built from scrap materials quickly spread across local and international media platforms, earning him praise as a symbol of African ingenuity and grassroots innovation.
Despite the publicity, the breakthrough did not translate into sustained institutional support. After completing high school, Petrus struggled to gain admission to university and only later managed to enroll in higher education. He eventually earned a degree in electronics engineering in 2023. However, he remains unemployed, and his invention has not progressed beyond the prototype stage.
While the technology behind the device—radio-frequency communication—has long been used in two-way radios and military systems, Petrus’ approach lies in adapting it into a mobile-style handset designed for everyday use. Experts note that such a concept could offer a low-cost alternative for communication in rural communities and regions with limited network infrastructure.
So far, no major academic institution, technology firm, or government agency has taken up the project for further development, testing, or mass production. Petrus has said he is willing to refine and improve the design if he receives the necessary resources and technical backing.
His story underscores a broader challenge facing many young innovators across Africa: groundbreaking ideas often emerge from modest settings but stall due to limited access to funding, research facilities, and commercialization pathways. In Petrus’ case, his invention also challenges the dominant telecom business model, raising questions about whether disruptive ideas can gain institutional support.
As Ghana and other African countries push narratives of digital transformation and innovation-driven growth, the experience of Simon Petrus highlights the gap that still exists between raw ingenuity and real-world opportunity. ]
Whether his SIM-free phone becomes part of Africa’s technological future may depend less on the invention itself and more on whether systems are willing to invest in ideas that operate outside established norms.

Young Self-Taught Black Inventor Julian Brown Develops Revolutionary Plastic-to-Fuel Technology
Atlanta, USA – A young Black inventor from Atlanta, Julian Brown, has stunned the scientific community and gone viral worldwide after developing a backyard process that converts everyday plastic waste into usable diesel, gasoline, and jet fuel.
Born in Tennessee and raised in Atlanta, Brown — a self-taught welder with no formal degree or laboratory — created a system called “Plastoline.”
Using an upgraded form of pyrolysis (a thermal decomposition process), enhanced with microwaves and solar energy for cleaner conversion, he built a small reactor capable of turning discarded plastics back into high-quality fuel.
Independent tests reportedly confirmed that the diesel and gasoline produced are among the most refined seen, and he has successfully powered vehicles with the fuel in live demonstrations.
Brown launched a startup called Nature Jab and began sharing his experiments on Instagram and TikTok, where the videos quickly gained millions of views globally. Despite suffering second-degree burns in a reactor explosion, he refused to abandon the project.
He attempted to raise $1 million to scale the technology but secured only tens of thousands of dollars. In July 2025, he posted that he was under attack before temporarily vanishing from public view.
He has since re-emerged, with supporters calling for his protection and greater investment in his work.
The innovation has sparked particular excitement across Africa, where plastic waste accumulates in massive quantities in landfills and communities.
Experts say Brown’s technology could offer a practical solution for turning waste into energy, addressing both environmental pollution and fuel shortages on the continent.
Commentators have criticised the lack of substantial support from investors and the broader community, questioning why a breakthrough with such transformative potential, especially from a young Black inventor, has not received wider backing.

MTN Signals Major Data Center Investment Plans in Ghana
Accra, Ghana – MTN Group is exploring significant investments in data centers in Ghana as Part of its digital push.
The telecoms giant says the move is a natural extension of its broader digital infrastructure strategy in one of its most important African markets.
Group Chief Executive Officer Ralph Mupita made the announcement during a strategic visit to Ghana at the beginning of 2026. He said the company is keen to partner with both public and private stakeholders to develop large-scale data centers that would enhance cloud computing, data storage, and digital service capabilities across the country.
Mupita stated that such facilities are critical to supporting Ghana’s long-term digital transformation and economic growth.
He acknowledged, however, that establishing world-class data centers would require addressing key infrastructure challenges, particularly reliable power supply, suitable land, and advanced cooling systems. MTN is therefore considering collaborative models to ensure projects meet both commercial viability and sustainability standards.
During his engagements, Mupita held discussions with MTN Ghana’s leadership, regulators, and senior government officials, including the Bank of Ghana, the Ghana Investment Promotion Centre, and Minister for Communications, Digital Technology and Innovations, Sam George.
He described Ghana as a priority market that “feels like home” and reaffirmed the Group’s commitment to deepening investments in digital infrastructure and financial inclusion.
On the fintech front, Mupita highlighted plans to expand mobile money services while working closely with the central bank to strengthen fraud prevention through artificial intelligence.
The visit underscored MTN’s ambition to remain a key partner in Ghana’s digital economy, driving innovation, job creation, and inclusive growth.
MTN Ghana (Scancom PLC) is the dominant telecommunications market leader in Ghana and has been recognized as a top-performing operation within the MTN Group. The company is actively shifting from a traditional telco to a technology platform company, with a focus on fintech (Mobile Money) and digital inclusion.

New Cashew Processing Plant and Fertilizer Facility to be Set Up in Ghana
Accra, Ghana – Ghana’s Ministry of Food and Agriculture has signed three Memoranda of Understanding with Chinese firm SENTUO Group Limited to drive agro-industrial growth through major new investments in processing, fertiliser production, and farmer support services.
The agreements, signed in Accra on Tuesday, include the establishment of a cashew processing plant at Sampa in the Bono Region and a fertiliser manufacturing facility. SENTUO will also roll out 30 Farmer Service Centres nationwide to improve access to quality inputs, mechanisation services, and technical support for farmers.

The projects are expected to create significant employment opportunities, particularly for young people, while enhancing value addition and reducing Ghana’s reliance on raw commodity exports.
Minister for Food and Agriculture Eric Opoku described the partnership as a major step toward the government’s Agriculture for Economic Transformation Agenda.
“We are ready to industrialise Ghana’s agriculture,” he said, adding that the cashew plant will process both nuts and apples to maximise returns across the entire value chain.
He emphasised the need to move from exporting raw produce to building a vibrant, value-driven agro-industrial economy.
The Chairman of SENTUO Group Limited, Xu Mingjuan, said the company’s nearly 20 years of operation in Ghana and the current government’s 24-hour economy policy had encouraged further investment. He confirmed that engineers have already started preliminary work on the projects.
The deals signal growing Chinese interest in Ghana’s agricultural transformation and are expected to strengthen food security, boost exports, and create sustainable jobs across the value chain.
