Korea's 5G Speed 2nd Fastest in World

The world's fastest 5G network is Saudi Arabia's rather than Korea's, which comes second although Korea was the first country to roll it out.

For availability Korea ranks a poor fifth with 22.2 percent coverage. Saudi Arabia leads with 37 percent, followed by Kuwait with just under 28 percent.
