Best Cox Mobile Plans (2025)

Cox Mobile, available exclusively to Cox Internet customers, keeps things simple by offering just two plans—a pay-by-the-gig plan, and an unlimited data plan. Both run on Verizon’s reliable 4G LTE and 5G networks and include unlimited talk and text with no contracts.

In this article, we'll explain what type of users these two respective plans are ideally suited for, as well as provide some wider context about what you can expect as a Cox Mobile customer.

Who is Cox Mobile For?

Since Cox Mobile is only available to Cox Internet customers, the service is for, first and foremost, current Cox subscribers.

Beyond that, though, Cox Mobile is priced and designed for consumers who feel turned off by the complication and expense of major carrier cell phone service. Cox Mobile offers a straightforward selection of two plans, instead of the larger variety of somewhat confusing options offered by the likes of Verizon, AT&T, and T-Mobile. What's more, Cox Mobile's plans cost a fraction of the price of standard major carrier offerings.

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. Check out Cox Mobile's (via Verizon's) coverage map below, to ensure service in the places you spend time: 

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 Phones

While Cox Mobile is particularly well-suited to customers who bring their own phones to the network, the carrier does offer a tidy selection of devices sale as well. This includes the latest iPhone 17 series.

Prefer to bring your own device (BYOD) to Cox Mobile? It’s easy to check your compatibility online via the carrier’s online tool, and fast to activate service if you have eSIM functionality in your phone (as most recent models do).

Cox Mobile Customer Service Support

Cox Mobile benefits from the broader infrastructure of the Cox Communications brand, allowing it to offer more robust and accessible customer service options than many smaller MVNOs. Subscribers can get help not only through Cox Mobile’s dedicated phone support and online chat but also at Cox retail stores, where trained staff can assist with billing, plan changes, and technical issues in person. Customers can also manage their accounts or request assistance through the Cox website or mobile app, creating a seamless support experience that combines the reach of a national provider with the flexibility of a modern mobile service.

The Bottom Line

Cox Mobile is one of several upstart ISP mobile carriers on the market that offer cheap cell phone service that can bebundled with internet. Cox Mobile’s use of Verizon’s excellent network makes it an attractive option if you’re looking for great coverage at a cheap price.

Frequently Asked Questions

What mobile plans does Cox Mobile offer, and which is best for me?

Cox Mobile offers two plans: Pay As You Gig, which charges around $15 per GB of data used, and Gig Unlimited, a $45 monthly plan that includes 20 GB of premium data before speeds slow down. The best plan depends on your usage. Light users who use under a couple of gigabytes each month may save more with Pay As You Gig, while heavier users will likely find better value in the Unlimited plan despite speed reductions after 20 GB.

Do I need to have Cox Internet service to get Cox Mobile?

Yes. Cox Mobile is only available to customers who have Cox Internet service. If you don’t have an active Cox Internet subscription, you won’t be eligible to sign up for Cox Mobile.

What happens after I exceed Cox Mobile’s high-speed data limit on the Unlimited plan?

After you reach 20 GB of high-speed data in a billing cycle, Cox Mobile slows your speeds to roughly 1.5 Mbps down and 750 Kbps up for the rest of the month. There are no overage fees—just reduced speeds until your next billing cycle begins.
