Qatar Telecom posted a 21% jump in full-year profit as it added new customers and expanded operations, Bloomberg has reported. Net income rose to 2.78 billion riyals ($764m) from 2.31 billion riyals a year earlier, the company said. Fourth-quarter profit dropped 7.9% to 431 million riyals as 'non-operational provisions' hurt earnings, it said, without giving further details.
