SK Telecom begins 3G network wind-down
SK Telecom (SKM) stopped new 3G subscriptions and began winding down the network, planning a full shutdown by 2027. It offered transition programs for existing 3G users, including discounts and subsidies. As of June, SK Telecom had 134,413 3G lines, about 0.6% of its customers. The company cited declining subscribers and traffic, along with aging equipment, for the decision.
