At least in the US, AT&T made the incredibly cynical move to rebrand their 4G service in areas where 5G was expected one day to be available as '5Ge' aka '5G Evolution'. That was so they could 'imply' in ads you were getting a 5G connection before, you know, there was a 5G network to connect to. Even changed the little icon on your phone from 4G to 5Ge. Sprint sued for the blatant false advertising and AT&T unsurprisingly settled.
