A Namibian secondary school student has invented a phone that allows people to call anywhere in the world without using airtime.
Simon Petrus, who studies at Abraham Iyambo Senior Secondary School in the country’s Ohagwena Region, created the phone using resources given to him by his unemployed parents.
He used spares from a phone and television set to create the device which gets its power from a radiator and uses radio frequency to make calls without a sim card. Whats more? Users can also watch a television channel on the handset.
The genius is however not a new inventor because last year he also created a two-in-one machine that works as both a seed drier and cooler. That invention won him a gold medal at national level.
But Petrus hopes the sim-less phone will break national boundaries and be successful at an international level.
It’s safe to say Africans are also wishing that the invention is promoted and improved.
They should also extend such wishes to another Namibian inventor Joshua Nghaamwa who has made a satellite using parts from radios, cellphones, and other electronics.
The satellite, believed to strengthen internet connectivity, is small enough to fit in a laptop bag and has a USB port that allows it to be connected to a modem, router or cellphone, increasing internet speed and allows for a better online experience.
Nghaamwa hopes his device will be adopted throughout Africa since he is sure that it can increase internet penetration across the continent.
