After a recent update some AT&T phones now have a 5G E icon. This icon replaces the one indicated the phone is running on a 4G network. But here’s the thing: The phone is still on a 4G network. AT&T has played these games before, too.

This nonsense is a marketing ploy by AT&T. The so-called 5G E (5G Evolution) network is just a beefed-up 4G network and not true 5G, which is still far from being ready for general consumption. AT&T used the same deceptive tactics before launching its LTE network.
