Cox Mobile Coverage Map

Like its competitor Spectrum Mobile, Cox Mobile makes use of Verizon’s national system of network for coverage. Verizon’s coverage is excellent in both rural and urban areas, thanks to a combination of powerful 4G and 5G towers.

There’s one caveat to be aware of, however: Verizon tends to prioritize its own subscribers during times of network congestion; if it’s especially busy, Cox Mobile customers may experience slightly slower speeds than Verizon customers.

Cox Mobile 4G LTE Coverage

Cox Mobile makes use of Verizon’s nationwide 4G LTE network to deliver coverage to its customers. By the numbers, Verizon wields the second-best 4G network in the country, with great coverage in rural and metropolitan areas alike. 

One look at the map above shows just how widespread Verizon’s—and, by extension, Cox Mobile's—4G network is. Apart from some isolated dead zones in rural areas of the Western United States, that 4G network is present just about everywhere.

Cox Mobile 5G Coverage

Cox Mobile also uses Verizon to provide 5G coverage to its customers. Verizon’s 5G network is a bit more limited in its coverage area than its 4G network, trailing the likes of AT&T and T-Mobile. 

However, where a 5G signal is present, Cox Mobile customers are likely to experience some of the fastest speeds around, thanks to Verizon’s Ultra Wideband 5G network. This 5G UW spectrum offers faster speeds, lower latency, and better reliability than standard 5G.

Here’s a breakdown of Cox Mobile’s 5G network: 

• 5G Nationwide: Built on low-band spectrum, this covers the majority of the U.S. and offers a modest boost over 4G LTE speeds.‍
• 5G Ultra Wideband: This is Verizon’s high-performance 5G, using mid- and high-band frequencies to deliver super-fast speeds and ultra-low latency.

Cox Mobile vs. Other Small Carriers

Cox Mobile is one of several internet service providers that have expanded into mobile service—a group that includes Spectrum Mobile, Xfinity Mobile, and Optimum Mobile. All of these carriers make use of larger cell phone carrier networks for coverage purposes. 

Like Cox Mobile, Spectrum Mobile and Xfinity Mobile rely on Verizon’s network for service. Optimum Mobile, on the other hand, uses T-Mobile’s network. 

The chart below gives you a sense of how Verizon’s network stacks up against the other major U.S. networks.

Simply put, Verizon offers the second-best 4G coverage, and the third-best 5G coverage, in the country.

Cox Mobile Phone Plans

Cox Mobile, available exclusively to Cox Internet customers, keeps things simple with just two plan options—one for light users and one for those who want unlimited data. Both plans run on Verizon’s reliable 4G LTE and 5G networks and include unlimited talk and text with no contracts.

• Pay As You Gig: $15/GB per month, pay for what you use. For users who mostly rely on Wi-Fi and only need mobile data occasionally.
• Gig Unlimited: unlimited data for $45/month. Best for moderate to heavy data users or families who want a flat monthly rate.

Both plans include access to Cox’s nationwide network of over 4 million Wi-Fi hotspots, helping customers stay connected while conserving mobile data.
