Based on prior announcements, it looks like Sprint will be the last of the four major carriers to kick start 5G service in the United States. But at least it now can add on three more big cities it plans to cover within the first half of next year.

The SoftBank-owned network has announced New York City, Phoenix and its hometown of Kansas City will be joining the six regions currently on the list: Atlanta, Chicago, Dallas, Houston, Los Angeles and Washington, DC. The company has been heavily promoting its leverage of 2.5GHzspectrum, what’s considered mid-band coverage in the more powerful 5G standard.
