SK Telecom Responds to Cyberattack with Major Customer Appreciation Campaign

In April, SK Telecom suffered a serious cyber incident that disrupted services, exposed user vulnerabilities, and resulted in the loss of nearly 200,000 customers. To restore trust and show appreciation to those who stayed, SKT is launching a five-month Customer Appreciation Event starting in August, featuring over 50% discounts from top brands and generous data bonuses. As part of its recovery efforts, the company is also offering all 25 million subscribers a free SIM card replacement—either as a new physical SIM, an eSIM, or via a secure SIM reset option—available through T World stores or online.
