The phone "is the result of years of collaboration to deploy an end-to-end solution for commercial 5G services using Samsung network equipment and personal devices," the companies said in a press release. 

The phone is the latest trickle of news for 5G, which is expected to significantly boost the speed, coverage and responsiveness of wireless networks. It promises to make phones upload and download data 10 to 100 times faster than the typical 4G LTE network today. That could mean downloading movies in seconds, rather than minutes.
