"We will become the number one operator of the next-generation intelligent platform,delivering the first and best 5G network services throughout South Korea."

The next-generation 5G technology is up to 20 times faster than the current LTE or 4G networks,offering extremely low latency and the ability to connect more devices at once. The South Korean government pledged this week to support the completion of the full-nationwide 5G network by 2022 and raise more than 30 trillion won to invest in the world's best 5G ecosystem.
