SK Broadband Speed Test FAQ
What is the relationship between SK Broadband and SK Telecom?
SK Broadband is a wholly owned subsidiary of SK Telecom, South Korea's largest mobile carrier. SK Telecom handles mobile (5G and 4G) services, while SK Broadband manages fixed-line fiber internet and IPTV. This relationship enables strong bundle discounts when you subscribe to both SK Telecom mobile and SK Broadband internet. The two companies share infrastructure and customer service resources. SK Broadband's B tv IPTV service also integrates with SK Telecom's content offerings.
How much can I save by bundling SK Broadband with SK Telecom?
Bundling SK Broadband fiber internet with SK Telecom mobile saves KRW 5,000 to 15,000 per month depending on your mobile plan tier. Adding B tv IPTV increases savings further. A typical household bundle of 1 Gbps internet, B tv with Netflix, and two SK Telecom 5G lines can save KRW 20,000-30,000 per month compared to separate subscriptions. The best discounts require a 3-year contract. SK Broadband also offers 1-year Direct plans with smaller discounts for more flexibility.
Is SK Broadband available in my apartment building?
SK Broadband fiber availability depends on your apartment building's installed infrastructure. Most newer apartments in Seoul and major cities have SK Broadband fiber pre-installed. You can check availability by entering your address on SK Broadband's website at skbroadband.com or by calling 106. If SK Broadband is not installed in your building, you can request installation, but this requires building management approval and may take several weeks. Older buildings without fiber infrastructure may need KT, which has the widest building-level coverage.
