Korean telecom service provider SK Telecom has announced that its revenues increased by 2.3% in 2012 in comparison to previous year due to LTE and growth of its enterprise business and subsidiaries. The operating income decreased by 23.3% YoY due to factors including increases in LTE marketing expenses driven by rapid growth of LTE subscribers and investment costs to upgrade networks to accommodate surging data traffic.
