After simultaneously launching commercial 5G services in early April, three South Korean carriers have collectively signed up 260,000 subscribers — a solid start for the next-generation cellular technology.

The key metric of 5G adoption was shared by South Korea’s Ministry of Science and ICT (via Yonhap), which scheduled and coordinated the carriers’ launches in an effort to make South Korea the world’s first 5G country.

South Korea’s haste to commercialize 5G services and devices has led to speed bumps for early adopters, who have complained about inconsistent service and issues with the country’s first 5G smartphone: Samsung’s Galaxy S10 5G.

But carriers have moved quickly to respond to those early concerns, if not fully resolve them, and have offered aggressive promotions to lure new customers to the high-speed wireless technology.

“Many of the initial complaints raised by consumers are being addressed,” said the Ministry of Science and ICT, “but with more people using the system, other problems are expected to come to light that will require fixing.”

Commencing 5G service is one thing, but having enough base stations and devices to satisfy a large population is another — the scalability challenge facing U.S. carriers with over 328 million residents to serve.
