Verizon made a major announcement this week, but it has more to do with Samsung than the nation's largest carrier.

The Galaxy S10, due out globally in early 2019, could be one of the first smartphones to work on Verizon's 5G network. Both sides are partnering to sell a 5G-ready mobile device that'll be released in the first half of 2019. Samsung's next flagship doesn't have anything set in stone at the moment, but multiple reports suggest 5G support will be among the groundbreaking features.

It's also possible that Samsung limits the feature to select markets and even models. The Galaxy S10 is expected to be offered in two sizes as usual, but the Wall Street Journal also revealed a cutting-edge third model will join them. Samsung's anniversary-inspired unit might be the only one to ship with 5G support.

Verizon started selling in-home 5G service earlier this year. It's available in Houston, Indianapolis, Los Angeles, and Sacramento.

The 5G network for wireless service will go live in early 2019. It won't have nationwide coverage from the start, but Verizon's pouring in resources for fast-growing expansion. Aside from that, Verizon also needs to wait until Samsung and other hardware manufacturers gets 5G-enabled modems into their mobile devices.
