More than 34-thousand subscribers to SK Telecom, the country’s largest mobile carrier, have reportedly switched to other carriers in the aftermath of a hacking incident that breached their privacy. 

According to telecom industry sources on Tuesday, 34-thousand-132 subscribers moved to other carriers the previous day, while SK Telecom gained 87-hundred-29 new customers, resulting in a net decrease of 25-thousand-403. 

About 60 percent of the departing customers switched to KT, the country’s second-largest carrier, with the rest moving to LG Uplus.

KT gained more than 21-thousand new subscribers, while nearly 15-thousand people signed on with LG Uplus. 

Earlier this month, SK Telecom detected signs of a massive leak of customers’ SIM card data due to a cyberattack, causing public anxiety about potential theft of personal information.
