SK Telecom Co.,South Korea’s top mobile operator reported a two-fold growth in its Q4 profit in 2012. They claimed that this was due to a decrease in marketing costs – meaning what? The results come as the country’s three mobile operators ― SK Telecom, KT Corp. and LG Uplus Corp. ― have been slowing down their marketing drive recently amid the communications watchdog’s move to cool market competition. In December last year, the Korea Communications Commission (KCC) fined the three firms a combined 11.9 billion won and imposed business suspensions for giving out excessive subsidies to lure LTE subscribers.
