A BOY FROM NAMIBIAN INVENTED A PHONE WITHOUT SIM CARD & AIRTIME ....
Namibian teenager has captured attention with an extraordinary invention. According to Africa Global News, Simon Petrus built a mobile phone that can make calls without a SIM card, airtime, or traditional network coverage.
Using recycled electronics, including parts from an old landline handset, a television, and a two-way radio, he designed a device that communicates through radio frequency technology. This allows the phone to connect directly with other radios over shortwave frequencies, bypassing conventional cellular infrastructure entirely.

Namibia Today reports that Petrus’s creation is more than just a phone. It also functions as a television, FM radio, cooling fan, and device charger, showing his ability to integrate multiple technologies into one unit.
He began developing the prototype while still a student, motivated by the lack of reliable mobile coverage in rural areas. His invention offers a glimpse of how innovation can provide accessible communication in places where traditional networks are limited or nonexistent.
While it is not yet a commercial product, Petrus’s work has drawn national praise and sparked conversations about the future of communication technology in Africa. His achievement demonstrates how creativity and resourcefulness can bridge gaps and bring solutions to real-world challenging the world
