Sources: 3. Developments: 2. SK Telecom has focused on enhancing customer trust and satisfaction through new metrics and service improvements. During its ‘2026 Insight Day’, the company announced plans to develop metrics for measuring corporate trust by analyzing actual customer behavior rather than relying solely on direct surveys. The company aims to use behavioral data—such as a reduced need for customers to manually verify information—as a proxy for trust, focusing on areas like pricing transparency, security management, and service stability. Following these strategic shifts, SK Telecom reclaimed the top position in the mobile telephony sector of the Korea Customer Satisfaction Index (KCSI). This achievement completed a ‘grand slam’ for the company, having also secured first place in the National Customer Satisfaction Index (NCSI) and the Korea Service Quality Index (KS-SQI). The company attributed this recovery to a ‘customer-centric’ business model, which included field-based experience activities and the integration of artificial intelligence to analyze feedback and preemptively address customer inconveniences. ## Timeline ### 2026-09-29: SK Telecom reclaims top spot in Korea Customer Satisfaction Index SK Telecom has reclaimed its top ranking in the Korea Customer Satisfaction Index (KCSI), completing a sweep of South Korea’s three major customer satisfaction surveys. 2 sources. https://clstr.news/cluster/sk-telecom-reclaims-top-spot-in-korea-customer-satisfaction-index ### 2026-09-21: SK Telecom develops customer behavior metrics to measure corporate trust SK Telecom is developing new corporate trust metrics based on customer behavior, aiming to use data such as reduced manual inquiries as indicators of service reliability and transparency. 3 sources. https://clstr.news/cluster/sk-telecom-develops-customer-behavior-metrics-to-measure-corporate-trust --- Cite as: SK Telecom customer satisfaction and trust initiatives.
