(Telecompaper) SK Telecom saw its first-quarter revenue reach KRW 4.229 trillion, which represents a decline of 0.3 percent year-on-year. The drop was mainly due to the elimination of sign-up fees and increased number of subscribers who choose contract-based mobile fee discounts, the company said. Despite reduced equity method gain from SK Hynix, the net income increased by 29.3 percent year-on-year, reaching KRW 572.3 billion at 31 March 2015, as SK Planet sold its controlling stake in Loen Entertainment in the first quarter of 2016.
