In a blog post that was also published as a full-page ad in the Wall Street Journal, New York Times USA Today and Washington Post, Verizon's chief technology officer Kyle Malady did not name AT&T directly, but said that companies that mislabel services as 5G risk confusing consumers. He said "the potential to over-hype and under-deliver on the 5G promise is a temptation that the wireless industry must resist."

Meanwhile, T-Mobile's CEO John Legere took to Twitter accusing AT&T of "flat out" lying to consumers to deliberately trick them into thinking the AT&T service is something that it's not.
