Verizon will soon offer 5G in select cities for $10 extra

Verizon's move into new cities is an attempt to entice wireless customers with the ultrafast speeds and low latency connections that 5G promises. The technology has been touted as a major breakthrough that will allow for more seamless streaming of videos and lightning-fast response times from self-driving cars. But while innovations in 5G technology are happening in several places in the United States, there isn't an existing network that's widespread enough to benefit the majority of wireless customers right away. The transition from 4G to 5G networks in the United States won't be widespread until 2020, and will involve infrastructure upgrades that cost companies billions of dollars. It will also require lots of testing.
