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.

T-Mobile has one stellar internet plan while Cox packs in a ton of variety. Which is best for you comes down to whether or not T-Mobile’s bandwidth meets your needs.

Cox certainly has more choices than T-Mobile and faster speeds. 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 intenret 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.

  • $50.00/mo. with any Voice plan*
  • 72–245MbpsView Plan

    T-Mobile only has one internet plan, but it’s a good one; mainly because the plan covers everything for one 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 245Mbps, 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.

    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

    OverallReliabilityCustomer service RatingSpeedPrice
    Cox3.7 /

    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.

    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.

    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 CapView on provider site
    Cox1,280GBView Plans
    T-MobileUnlimitedView 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

    Cox1-year, month-to-month option for $10/month extra, or prepaid (new)View Plans
    T-Mobilemonth-to-monthView 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.
