South Korea's 5G mobile communication service was first introduced in April 2019. The number of users increased to some 11.8 million in 2020 and 20.9 million in 2021. Since the latest generation mobile network service was launched, mobile carriers competitively gave away hefty rewards and subsidies for users who subscribe to the new 5G service.
According to a 2020 survey of 800 5G service users, conducted by the Korea Consumer Agency, 34 percent said that they registered to a 5G smartphone service because they wanted to use the latest 5G smartphones. 29.4 percent said that they switched to the ultra-fast mobile data service because mobile carriers provided larger amounts of subsidies than 4G services.
Data released by the science ministry showed that there were 28,059,343 users subscribed to 5G services as of December 2022. Meanwhile, LTE mobile data service is steadily losing subscribers to stand at 46,217,456, down 4.3 percent from 2021's 48,288,764.
Other than ordinary mobile data networks, LTE broadband is widely used in South Korea for public purposes including the management of vehicle-to-everything (V2X) networks, autonomous vehicle driving assistant infrastructure, and emergency notification services.
