5G & LTE Quality and Speed

* Q1. What is the average 5G speed in South Korea?
-A. As of June 2026, the nationwide average speed across the top three carriers is around 1 Gbps. It provides a highly stable connection, so you can enjoy seamless web surfing and social media shorts, as well as high-definition video streaming and large file downloads without any lag.

* Q2. What is the average LTE speed in South Korea?
– A. The nationwide average speed for the top three carriers is around 100 Mbps. While it is about one-tenth of the 5G speed, it is still fast and reliable enough for everyday activities like watching YouTube videos and browsing the web.

* Q3. How fast is the 5Mbps speed limit provided by KT?
A. The 5 Mbps speed limit, which kicks in after you exhaust your basic data (e.g., 3GB), is a very practical speed. While it might not support ultra-high-definition (4K) streaming, it is perfectly fine for daily use. You can comfortably watch videos on YouTube or Netflix, browse the web, use messaging apps like KakaoTalk, and even connect your laptop or tablet via mobile hotspot (tethering).
