T-Mobile pokes fun at AT&T for labelling its 4G service as 5G

4G curiously becomes 5G overnight, with no change in the company’s infrastructure or customers' device hardware T-Mobile has cast aspersions at rival operator AT&T for changing the 4G icon on its users' devices to 5G-E, despite not offering a true 5G network as yet. In a tweet replying to a Verge article about the labelling, the operator posted a fun-poking video with someone essentially sticking a post-it note on a phone labelled '9G'. 4G runs on LTE technology while true 5G runs on mmWave technology, but AT&T's peculiar rebranding of its network to one bearing the 5G name happened over the weekend despite no physical upgrades from the customers to 5G-enabled devices, or any new infrastructure in place to deliver the new technology.
