We had earlier reported that a Namibian grade 12 learner recently invented a phone 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 photo of what Petrus' invention looks like has been released.
