Verizon's 5G network is getting a big boost this month, promising faster speeds and wider coverage for the phones, tablets and other devices on its service. Verizon's 5G upgrade is happening on Jan. 19, after a two-week delay. The move will cover 100 million people this month and further help Verizon catch up to T-Mobile, which currently has the largest 5G network in the US, thanks to its merger with Sprint two years ago.

If you want to take immediate advantage of the faster Verizon 5G network, you'll need to have the right device. The good news? By the time the network turns on in two weeks, "upwards of 90%" of Verizon customers are expected to be able to tap into the new 5G connection, Kyle Malady, Verizon's chief technology officer, told CNET Tuesday.

"A lot of devices already have the right software in them," Malady said. "We've been testing the devices, and we've been working with the manufacturers for a long time now so all the software is ready to go."

What to know about Verizon's new 5G network

Verizon spent over $50 billion last year to purchase what is known as C-band spectrum. Verizon's current 5G network relies on a combination of 5G technologies known as millimeter-wave and low-band spectrum. Millimeter-wave has excellent performance but significantly limited coverage that often is only available on certain street corners or in select parts of stadiums, airports or arenas. Low-band offers strong coverage, but its performance is often equivalent to 4G LTE. 

With the addition of C-band, Verizon will be able to add a 5G network that operates in the middle, bringing much faster performance than low-band 5G while offering significantly better coverage than millimeter-wave. 

On Tuesday the carrier said that it will cover 100 million people with the new C-band network, which will operate alongside millimeter-wave under its "Ultra Wideband" branding, when it goes live on Jan. 19. 

A Verizon spokesperson says that other phones, such as Google's Pixel 6 line, will "receive software updates to enable C-band access in the coming weeks." The spokesperson adds that "going forward every 5G device Verizon sells to postpaid customers will be C-band compatible and we will have more than 20 C-band-compatible devices by the end of the year." 

While it is important to have the right device, Verizon also requires that those planning to use C-band or its millimeter-wave network subscribe to its higher-priced unlimited plans. This includes the Play More, Do More and Get More options available today as well as the older Above and Beyond unlimited plans it offered a few years ago. 

Those on other plans will not be able to use C-band, even if they have a device that supports it.
