Young Namibian Inventor Develops SIM-Free Phone Powered by Radio Waves

Young Namibian Inventor Develops SIM-Free Phone Powered by Radio Waves. A young Namibian innovator, Simon Petrus, has captured national attention with his groundbreaking invention: a SIM-free mobile phone that operates using radio frequency technology, eliminating the need for traditional cellular networks.

Built entirely from discarded television and cellphone components, the multipurpose device allows users to make calls without a SIM card or airtime. Beyond its communication function, the invention doubles as a television, FM radio, cooling fan, and device charger—showcasing Petrus’s ability to integrate multiple technologies into a single unit.

Petrus, who graduated in electronics engineering through self-study, rose to prominence after winning a national high school technology competition with his prototype. The project impressed judges with its ingenuity and practical application, especially in rural areas where access to mobile networks remains limited.

Despite his achievement, Petrus now faces the harsh reality of unemployment and limited resources. Without funding or mentorship, advancing his invention into a commercially viable product remains a challenge. He has called for support from the private sector, government, and innovation hubs to help him continue building sustainable, homegrown technologies.

Industry observers see Petrus’s innovation as a potential game-changer, particularly for communities in remote parts of Namibia and other African countries where network infrastructure is scarce or unreliable.
