Simon Petrus, a 19-year-old student from Namibia, has stunned the tech world by building a SIM-free phone capable of making calls without any mobile network. Using radio frequency communication, his homemade device bypasses the need for SIM cards, cell towers, or internet—making it a game-changer for remote areas lacking infrastructure. Built using scrap electronics and a radio transmitter, the device even includes a working television screen and a camera. Simon’s invention not only highlights the ingenuity emerging from underrepresented regions, but also paves the way for future innovations in offline communication technologies. #NamibiaInnovation #TechProdigy #RadioPhone #SIMFree #YoungInventors
