We've noted for a while now how mobile carriers don't seem particularly aware that they're associating 5G in the minds of American consumers with hype and bullshit. AT&T's efforts to use bogus phone icons to pretend 4G is 5G; Verizon's tendency to dramatically overstate availability; scant handset support and annoying surcharges; overly ambitious marketing means that consumers' first contact with 5G is generally one of disappointment.

That's not to say that 5G won't be a solid improvement when it arrives at scale, just that carriers were abundantly eager to overstate what 5G can do and where it's available, and didn't stop to think that they were doing the technology a disservice.
