A crowd is seen gathered near a SK Telecom roaming center in Terminal 1 of Incheon Airport on Wednesday, as travelers rush to swap their USIM cards before traveling abroad.
SK Telecom, a Korean mobile carrier with 25 million users, is offering free USIM card replacements as part of its response to a recent data hacking incident. The severity of the data breach is the worst in the history of the country's telecommunications industry, SK Telecom CEO Ryu Young-sang said Wednesday. (Photo by Yonhap)
