Why pay two different companies for your internet service and phone plan if you don’t have to? Internet service providers (ISPs) are rapidly moving into the wireless industry, offering excellent cell phone and internet bundles that help customers save money and simplify their bills. Two of the biggest internet providers offering phone plans are Cox Mobile and Spectrum Mobile. To hook up with either of these carriers, you must first pick one of their internet plans, then you can get access to a low-cost phone plan.
So, who is the better carrier between Cox Mobile and Spectrum Mobile? Both offer fairly similar options and include service on Verizon’s 5G network. That said, Spectrum Mobile takes the win in some of the most important categories. These include lower pricing, larger high-speed data allotments, and offering mobile hotspot data. On the other hand, Cox Mobile has a massive public hotspot perk for customers who want to conserve data.
Read on to learn more about these carriers and which one offers the best plan to fit your needs.

Cox Mobile vs. Spectrum Mobile: Coverage
The coverage between Cox Mobile and Spectrum Mobile is exactly the same. Both carriers rely on Verizon’s 4G LTE and 5G networks. Verizon’s 4G LTE network is the largest in the nation. While its 5G network isn’t quite as large as the networks from AT&T and T-Mobile, Verizon does offer some of the fastest speeds. This is due to the carrier's use of 5G ultrawide band towers that offer lightning-fast connectivity and plenty of bandwidth.

Cox Mobile vs. Spectrum Mobile: Price
The price category is one of the most important and Spectrum Mobile easily snags the win here. All of Spectrum Mobile’s plans are cheaper than Cox Mobile’s offerings, including unlimited data plans and a by-the-gig plan.
Cox Mobile vs. Spectrum Mobile unlimited plans
Spectrum Mobile offers two unlimited plans while Cox Mobile only offers one. Spectrum Mobile’s lower-tier Unlimited Data Plan starts at $29.99/month. It includes 20GB of premium data and a 5GB mobile hotspot. Cox’s Gig Unlimited Plan starts at $45/month and also offers 20GB of premium data. However, despite the higher price, it doesn’t include any mobile hotspot data.
- $45/month
- 20GB premium data
- No mobile hotspot capability
- $29.99/month
- 20GB premium data
- 5GB mobile hotspot
What about Spectrum Mobile’s other unlimited plan? The Unlimited Plus Data option offers 40GB of premium data and a 5GB mobile hotspot for $39.99/month. As you can see, it’s still cheaper than Cox Mobile’s unlimited plan yet offers twice the premium data allotment.

Cox Mobile vs. Spectrum Mobile gig plans
Not everyone needs an unlimited plan, so both Cox Mobile and Spectrum Mobile offer by-the-gig plans that allow you to purchase data one gig at a time. These are also considered “shared data” plans, meaning a family can share a single data allotment on multiple lines for huge savings.
Gig plans are best for people who don’t use much data. While the initial cost is cheaper, these gig plans only include 1GB of data. If you need more, you’ll have to buy it one gig at a time. That can add up very fast.
Once again, Spectrum Mobile takes the win, albeit narrowly this time. Spectrum Mobile’s 1GB By the Gig plan starts at $14/month. It also lets you use your gig plan as a mobile hotspot, just remember this cuts into your data allotment. Cox Mobile’s Pay As You Gig plan offers 1GB of data and costs $15/month. It doesn’t include a mobile hotspot feature.
- $15/month
- 1GB premium data
- No mobile hotspot capability
- $14/month
- 1GB premium data
- Mobile hotspot capability
Winner: Spectrum Mobile
Cox Mobile vs. Spectrum Mobile: Perks
Cox Mobile and Spectrum Mobile are both smaller carriers, so neither offers much in the way of perks. In fact, the main offering from both is a series of public Wi-Fi hotspots located across the country. You’d think that means this category is a tie, but you should note Cox offers a few more hotspots than Spectrum.
Cox Mobile offers four million public Wi-Fi hotspots across the country. Spectrum Mobile is limited to around 500,000 public Wi-Fi hotspots. If you need consistent access to a public hotspot to save data, like if you purchased a gig plan, Cox Mobile is the better option.
Winner: Cox Mobile
Cox Mobile vs. Spectrum Mobile: High-speed data
Spectrum Mobile wins this category by offering the largest high-speed data allotment. That’s the 40GB of premium data included with the Unlimited Plus Data Plan. Cox Mobile’s Gig Unlimited Plan only offers 20GB of high-speed premium data.
- $45/month
- 20GB premium data
- No mobile hotspot capability
- $99.99/month
- 40GB premium data
- 5GB mobile hotspot
Winner: Spectrum Mobile
Cox Mobile vs. Spectrum Mobile: Mobile hotspot
This is not a complicated category, since only Spectrum Mobile offers mobile hotspot allotments with its plans. None of Cox Mobile’s options include mobile hotspot capability.
Both of Spectrum Mobile’s unlimited plans offer a 5GB mobile hotspot. If you use up that allotment, it won’t shut off, but your speeds are limited to 3G. Spectrum’s 1GB By the Gig plan also includes hotspot capability, but your usage comes out of the plan’s overall data allotment.
Winner: Spectrum Mobile
Cox Mobile vs. Spectrum Mobile: Family plans
Both carriers offer family plans, but we need to dive a little deeper to understand which is truly better.
Cox Mobile’s Gig Unlimited Plan offers multi-line discounts with family plans. Cox makes each line cheaper for the first four lines and caps family plans at five lines in total. You can see how that pricing works below:
Gig Unlimited family plan pricing per line
| Lines | Price |
|---|---|
| 1 | $45/line |
| 2 | $40/line |
| 3 | $35/line |
| 4 | $30/line |
Spectrum Mobile also offers family plans, but no multi-line discount. You’ll simply pay the full cost of each line. You can also mix and match plan types to customize your family plan, so you can save money by picking a line that perfectly fits each member of your family.
Both carriers by-the-gig plans are also eligible for family plans with everyone sharing the single data allotment.
This was a difficult category, but we’re narrowly awarding Spectrum Mobile the win here. Spectrum offers mobile hotspot data with all its plans and its gig plan is slightly cheaper than Cox Mobile’s. The ability to mix and match plans is also a great feature not available with Cox. Overall, you’ll get more bang for your buck with Spectrum Mobile. Cox Mobile does offer the family plan discount, but you need four lines to get the price down to the same cost as Spectrum’s lower-tier Unlimited Data Plan. Still, if you want a Cox Mobile plan, you should absolutely join a family option to get the best possible prices.
Winner: Spectrum Mobile
Cox Mobile vs. Spectrum Mobile: Customer service
Neither Cox Mobile nor Spectrum Mobile are beloved for their customer service. This is true across the internet and wireless industries.
The good news is both carriers offer brick-and-mortar stores in the regions they cover, so you can probably find in-person help if you need it. Plus, there are customer service lines you can call and online help too.
TrustPilot gives both Cox and Spectrum a current rating of 1.2 out of 5. The Better Business Bureau isn’t much kinder with Cox receiving a 1.12 out of 5 and Spectrum Mobile getting a 1.26 rating. That said, all of these reviews are difficult to parse out. Most of them actually focus on problems with internet service, not their mobile plans. Most of the positive reviews focus on being helped by a specific individual on the phone or in a store. Your experience will most likely depend on the knowledge and temperament of whatever technician you happen to contact when needing help.
Winner: Tie
Cox Mobile vs. Spectrum Mobile: Recap
In the battle for carrier supremacy, Spectrum Mobile won many of the most important categories. It generally offers cheaper prices, has the largest high-speed data allotment overall, allows customizable family plans, and includes a mobile hotspot. Cox Mobile’s plans are a bit more expensive, but it also offers millions of public Wi-Fi hotspots as a perk and includes a multi-line discount with its unlimited family plan.
If you’re simply interested in saving money or need mobile hotspot, Spectrum Mobile is probably your best option. If you want a cheap gig plan with access to millions of public hotspots that help you conserve data, Cox Mobile is a better choice.
In truth, you’ll probably have a good experience with either of these carriers. Just remember that these mobile plans only come with an internet bundle from their respective providers. So, which internet service is available to you is also very important. If you can only get internet service with one provider, that’s the carrier you’ll have to pick.
Cox Mobile or Spectrum Mobile: Which is best for me?
If you’re looking for the cheapest carrier overall, Spectrum Mobile is the best option since it offers cheaper unlimited plans and gig options. That said, if perks like public hotspots or getting a multi-line discount on a family plan are important features to you, Cox Mobile might be the better choice.
