Compare Cox and T-Mobile head to head
T-Mobile provides one of the most hassle-free and all-inclusive services we’ve seen yet. Fast speeds, great perks, and a breezy setup all come at a very good price.
Cox has more options and even faster speeds, but tends to be a little more pricey and complicated. For most customers, it comes down to whether or not you need Cox’s faster speeds and if those speeds are worth giving up T-Mobile’s low pricing and convenience.

Plans and pricing: Cox vs. T-Mobile
T-Mobile and Cox offer a variety of plan options. Which is best for you comes down to whether or not T-Mobile’s bandwidth meets your needs.
Cox plans and pricing
| Plan | Price | Download speed |
|---|---|---|
| Fast | $50.00/mo.* | Up to 300Mbps |
| Go Even Faster | $80.00/mo.* | Up to 500Mbps |
| Go Super Fast | $110.00/mo.* | Up to 1,000Mbps |
| Go Beyond Fast | $150.00/mo.* | Up to 2,000Mbps |
*Excludes taxes and fees. No annual contract. For 24 mos.
Cox certainly has faster speeds than T-Mobile. Cox’s cable internet is one of the main broadband workhorses in the U.S.; it’s fast, reliable, and readily available. But keep in mind, Cox’s advertised prices are not as worry-free as T-Mobile’s due to extra fees like modem rental and installation fees.
Installing cable internet is also more of an ordeal because of the need for coaxial cabling to and throughout your home. However, if you want ultrafast speeds, Cox has them.
T-Mobile plans and pricing
| Package | Price | Speed |
|---|---|---|
| Rely Home Internet | $50.00/mo.* w/ Auto Pay | 87–318Mbps |
| Amplified Home Internet | $60.00/mo.* w/ Auto Pay | 133–415Mbps |
| All-In Home Internet | $70.00/mo.* w/ Auto Pay | 133–415Mbps |
*with AutoPay, taxes and fees included.
T-Mobile has five internet plan options and they are all solid; mainly because they cover everything for a low price: there are no hidden monthly fees, rental costs, or price hikes. You get fast service, unlimited data, no annual contract, and a free rental gateway.
With speeds up to 415Mbps, T-Mobile’s fixed wireless is fast enough for the majority of households. In our home test of T-Mobile’s home internet, we almost always clocked speeds at or above the advertised speed range, but the quality of service will depend on how good your home’s 5G reception is.
In general, a 5G wireless signal, like that used for T-Mobile’s internet service, is going to be less stable than Cox’s cable internet. But, again, we didn’t experience any issues in our home test, and according to our annual customer satisfaction survey, reliability isn’t an issue for most T-Mobile Internet customers.

Extra fees: Cox vs. T-Mobile
| Equipment Fee | Installation Fee | Other Fees | |
|---|---|---|---|
| Cox | $13.00/mo | $100.00; free self-installation | $10.00/mo. (early termination), late fees based on state laws and regulations |
| T-Mobile | Free rental gateway | None | None |
T-Mobile has no extra fees: no install fee, no equipment rental fee, and no data charges. Cox, is the opposite, packing all the usual ISP charges, with the $100 installation fee being a particularly tough pill to swallow.
Customer ratings: T-Mobile vs. Cox
| Overall | Reliability | Customer service Rating | Speed | Price | |
|---|---|---|---|---|---|
| Cox | 3.7 / 5 | 3.7 | 3.8 | 3.9 | 3.4 |

T-Mobile received the highest scores in our annual customer satisfaction survey. T-Mobile customers reported being satisfied with every aspect of T-Mobile but were especially happy with their pricing; T-Mobile received the highest price satisfaction score in the history of our survey among national ISPs.
Cox also received high ratings, consistently scoring in the top half of every category. But, between the two, T-Mobile takes the cake when it comes to customer satisfaction.

*Prices include applicable monthly recurring service fees and applicable discounts. Excludes charges for existing Cox services. Additional one-time charges, activation fees and monthly equipment fees may apply. Prices do not include applicable taxes, usage-based charges, fees, and surcharges, which are subject to change. Prorated charges may appear on your bill if you change services before the bill cycle is complete.
TV and internet bundles are one area where T-Mobile can’t compete as it doesn’t offer TV service. Cox on the other hand has over 10 different TV and internet bundles to choose from, making it easy to find something that fits your needs. Cox’s bundle discounts are modest, but it is convenient having your internet and TV service grouped under the same bill.
Internet types: Cox vs. T-Mobile
| Internet type | View on provider site | |
|---|---|---|
| Cox | Cable | View Plans |
| T-Mobile | 5G Fixed-wireless | View Plans |
Cox’s cable internet has a leg up on T-Mobile’s fixed-wireless. Cable internet is faster, more reliable, and has better latency than fixed-wireless. This is why Cox is able to offer faster speeds. Internet tech has come a long way in the last decade, but you still can’t beat a solid wired connection. If you need uncompromising stability and ultra-fast gig speeds, Cox is the way to go.
That being said, our experience with T-Mobile’s fixed wireless was outstanding. We had it running side-by-side with a Cox cable internet connection and didn’t notice much difference. The T-Mobile connection was a little less stable, but it was barely noticeable. The low price and added convenience of T-Mobile’s service easily make up for this minor shortcoming.
Data caps: Cox vs. T-Mobile
| Data Cap | View on provider site | |
|---|---|---|
| Cox | 1,280GB | View Plans |
| T-Mobile | Unlimited | View Plans |
T-Mobile’s unlimited data means you don’t have to stress counting gigabytes or worry about data overage fees. Cox imposes a standard 1.28TB data cap, but that’s more than enough for most households. In the US, average internet monthly data use is around 600GB, about half of Cox’s 1.28TB data cap.
Contracts: Cox vs. T-Mobile
| Contract length | View on provider site | |
|---|---|---|
| Cox | 1-year, month-to-month option for $10/month extra, or prepaid (new) | View Plans |
| T-Mobile | month-to-month | View Plans |
T-Mobile continues the theme of simplicity and convenience with its month-to-month internet plan that you can cancel at any time with no penalty. Cox takes a more standard approach, with 12-month contracts on most plans. You can get a month-to-month plan with Cox, but it costs extra.
Installation: Cox vs. T-Mobile

Both T-Mobile and Cox offer a free self-installation. T-Mobile’s self-installation is a lot easier due to not requiring any networking cables. For a self-install to work with Cox, your residence needs to have an active connection to Cox’s cable internet network.

Final call: Cox vs. T-Mobile
If you have average internet needs and want a hassle-free internet service at a great price, T-Mobile is the way to go. It’s fast enough, the setup is super easy, and you don’t have to worry about any pesky fees or data limits. On the other hand, if you need a lot of bandwidth for a large household or intense internet use, Cox’s cable internet is technically superior. It delivers up to gig speeds and comes with the reliability of a wired network.
