It's Sprint's turn to commit to a 5G network launch. The carrier has confirmed that full-fledged 5G service will debut in May in Atlanta, Chicago, Dallas and Kansas City. Houston, Los Angeles, New York City, Phoenix and Washington, DC will follow before the first half of 2019 is over. It's not certain which devices will be available on launch day, although Sprint has already committed to offering the LG V50 ThinQ and HTC 5G Hub in the spring. The Galaxy S10 5G is due in the summer.
