SEOUL, June 30 (Korea Bizwire) — South Korea’s Ministry of Science and ICT announced Monday it will reassign all 370 MHz of mobile communication spectrum, including bands used for 3G services, to existing telecom operators, ensuring the continuation of older networks for the time being.
The decision follows concerns over potential service disruptions for remaining 3G users, as SK Telecom and KT still operate 10 MHz each in 3G frequencies. The government cited service continuity and user protection as key reasons for the reallocation. LG Uplus, which transitioned directly to LTE, does not hold any 3G spectrum.
“No telecom provider has submitted a formal request to shut down their 3G services,” a ministry official said. “If such a request is made, we will evaluate it based on user protection plans and other factors.”
Though LTE (4G) services could technically continue without the reallocation of some spectrum, the ministry opted to reassign all 350 MHz to prevent potential degradation in network quality, particularly as a large portion of 5G users still rely on 4G networks for coverage support.
The ministry is also in discussions with telecom operators and industry experts about additional 5G spectrum allocation. A broader policy roadmap, including considerations for AI-driven services and future 6G commercialization, is expected by the end of the year.
