No, their 5G is 5G - their "5Ge" is LTE.
They have 5G in parts of 19 cities– Atlanta, Austin, Charlotte, Dallas, Houston, Indianapolis, Jacksonville, Los Angeles , Louisville, Nashville, New Orleans, Oklahoma City, Orlando, Raleigh, San Antonio, San Diego, San Francisco, San Jose and Waco.
They have "5Ge" (LTE) everywhere else.
It was colossally dumb, misleading, and sleazy for them to have started with that "5Ge" crap. They deserve the skepticism and ridicule (like your comments) that they get now from pulling that stunt. I just wanted to clear up confusion for others.
