South Korea's top mobile carrier SK Telecom, the only mobile carrier currently operating in the country, started selling Samsung Electronics Co.'s latest Galaxy lineup at home Thursday, without receiving prior consent from the tech giant. SK Telecom said the Galaxy S5, first shown at the Mobile World Congress in Barcelona, Spain last month, is now available for purchase, with the price slated at 866,800 won (US$806.1) but can be discounted to as low as 660,000 won for long-term subscribers.
