South Korea's largest wireless telecommunications operator.
SK Telecom's 5G in Seoul is blisteringly fast, downloads finish before I can blink and streaming is instant. Coverage is excellent across the whole metro area. The only reason it's not five stars is that the plan I'm on is a touch expensive compared to some smaller carriers.

Day to day SK Telecom has been excellent, fast data, strong coverage, and reliable calls across Seoul and beyond. I'm a happy customer. The only thing that occasionally trips me up is the app freezing when I try to view detailed usage, but it's a small flaw in an otherwise great service.

SK Telecom has lived up to its name as Korea's leading carrier. The 5G speeds are phenomenal, the signal is flawless even deep in the subway, and the customer service handled my plan change quickly and in clear English. Worth every won for the reliability and performance.
Flawless signal and excellent support
There's no denying SK Telecom has top-tier coverage and speed across Korea, which I appreciate daily. At the same time, I keep noticing budget carriers offering similar data for less, which makes me question whether I'm paying a premium just for the brand. Solid service, uncertain value.

I've been with SK Telecom for a while and the membership perks and discounts at partner stores genuinely add up. The network is dependable for calls and data wherever I go in Korea. My one small gripe is that the app's English support could be more complete for foreign residents.
Reliable network and valuable perks
Limited English in the app
