(Telecompaper) T-Mobile US said it lit up the country's first nationwide 5G network, covering more than 200 million people and more than 5,000 cities and towns all across the country. The 5G network covers more than 1 million square miles, much of that in rural America. If the merger with Sprint closes, the new T-Mobile will be able to build on this foundation to deliver "transformational broad and deep 5G for all", the company said.
