A Grade 12 learner in Namibia has invented a phone that doesn't need airtime to make calls. The schoolboy in the country’s Ohagwena Region came up with a sim-less mobile phone that does not require airtime to make calls to solve the country's problem.
The boy identified as Simon Petrus, a pupil at Abraham Iyambo Senior Secondary School created the phone using spares from a phone and television set, New Era reports.
The phone is complete with a light bulb, fan and charger socket, the handset functions off power supplied through a radiator and is able to make calls to anywhere through the use of radio frequencies.
