Mobile plans in Seoul ranked among the most expensive across six major global cities, with SK Telecom’s 4G fees highest for 20GB and 50GB monthly data. The plans cost 6,916 Japanese yen, or 60,846 Korean won, making Seoul’s price 2.3 times Tokyo’s and 2.8 times Paris’s. Seoul also ranked second for 4G 100GB and third for unlimited plans. For 5G, Seoul ranked second for 20GB at 4,902 yen, third for 50GB at 5,603 yen and third for unlimited service at 8,754 yen, or 77,017 won. The comparison examined the cheapest plans available to new subscribers from leading carriers in Seoul, Tokyo, New York, London, Paris and Düsseldorf. A separate comparison found LG Uplus ranked second for 20GB, 50GB and 100GB plans across 4G and 5G, while its unlimited plans were the most expensive. The Korea Telecommunications Operators Association said the methodology may have overstated South Korean fees because LTE and 5G plans are integrated domestically. A Consumers Union of Korea survey found median monthly data use at 28GB, with 40.4% of users on unlimited plans. International network-performance data placed Korea fourth to sixth globally for mobile download speeds, excluding some West Asian countries.
