Cox provides a great customer experience and reliable speeds, but you’ll spend more for higher-speed plans, extra data, and add-ons.
T-Mobile provides an inexpensive 5G internet plan with no contract and decent speed, but not a lot of choices or professional installation.
Cox plans range from around $0.60/Mbps for low-speed plans to around $0.10/Mbps for the fastest plan, which is more expensive than other cable internet providers. The good news? Cox has more lower-speed plan options, so if your internet budget tops out at $50 a month, Cox might be your new best friend. At speeds of 200 Mbps and above, however, Cox loses the price war.
What you get for the money is pretty good. All plans have a 1.25 TB data cap (unless you pay an extra $50 per month for unlimited), but that’s more than most people need. And unlike providers where unlimited comes standard, Cox won’t throttle your speed if you get a little data-hungry. Just beware of overage charges (which can really add up) if you go over the limit.
T-Mobile 5G Home Internet comes in one download speed (100 Mbps), which is fast enough for a lot of people but slower than most cable plans (up to 1 Gbps) and fiber plans (up to 5 Gbps). The good news? T-Mobile’s plan includes unlimited data, but there may be slowdowns when the network is congested. It’ll cost you $50, which is $0.50 per Mbps, and about right for 5G plans. However, overall, 5G internet is super cheap compared to other kinds of broadband internet. The Federal Communications Commission (FCC) benchmarks similar broadband plans at $105.67/month, (1) which comes out to more than a dollar per Mbps!
Even better, if you’re already a T-Mobile customer with a qualifying Magenta plan, your rate is $25/month. If max download speeds of 100 Mbps works for you, T-Mobile 5G Home Internet is a pretty sweet deal, especially if you’re already a customer. But if you’re looking for more plan options, you won’t find them here.
Generally, Cox delivers the speeds it says it does, sometimes even a bit higher—though the speed you experience also depends on lots of factors, such as the equipment you’re using and your distance from the router.
Cox specializes in cable internet, which is faster than DSL and satellite, but slower and less reliable than fiber. It’s also typically cheaper and more reliable than wireless internet. The US Federal Communication Commission, in fact, says actual speeds from Cox are faster than advertised and nearly identical to competitor Optimum. Those speeds are stable, too. The report found slowdowns less than 5% of the time. (1) However, cable internet is known to be slower during peak usage times because you and your neighbors are all using the same street lines.
As with any fixed wireless internet provider, speeds fluctuate widely and can be affected by weather, terrain, peak hours, and more. That means you’ll rarely get a steady 100 Mbps. T-Mobile says you’ll likely see anywhere from 33 to 182 Mbps for download and 8 to 25 Mbps for upload. (2) But we think T-Mobile should toot its horn a little louder. Independent research shows speeds average out to around 119 Mbps for download and 16 Mbps for upload—both of which leave other wireless ISPs in the dust. (3)
Generally, 5G internet isn’t as fast as cable internet (up to 1,000 Mbps, or 1 Gbps) or fiber (up to 5 Gbps). But for most people, it’ll feel pretty zippy. Unfortunately, if you’re using your connection for gaming, the inconsistency could cause unpredictable, frustrating lags.
Cox’s Panoramic Wi-Fi Gateway ($13/month to rent) is a modem and router in one, and you can purchase (but not rent) additional Wi-Fi pods ($129.99 each) that plug into a regular power outlet to reduce dead spots in your home. Because these pods can be used only with Cox, they're only an ideal solution if you plan to be with Cox for several years. The good news is Cox is also compatible with tons of other modems and routers, so you could save a few bucks while using your own gear.
With Cox, a self-installation kit is free. But if getting set up on your own makes you sweat, a Cox professional can install it for $100... but that installation cost goes up if your home isn’t already wired up and ready to go. They’ll ensure cabling makes it from the street into your home, but you might need to hire a contractor or handyman to run wires to a specific room.
T-Mobile uses a 5G gateway (included at no additional cost) to turn cell signal into Wi-Fi for your home. It’s strong enough to send signal about 30 feet away, depending on how many walls are in the way. It’s compatible with most mesh network extenders. Plus, you can create up to four separate networks, so you can create one for Airbnb guests or your least favorite roommate.
According to T-Mobile, installation should take around 15 minutes—if you have an Android or iOS phone and can download the T-Mobile internet app. If that doesn’t work out, you can call T-Mobile customer service and someone will help you get set up. If you don’t get cell signal or a landline at home, though, you’re going to have a rough day.
Reviews for internet service providers are notoriously low in general, but Cox does pretty well according to our real customer reviews. The American Customer Satisfaction Index (ASCI) ranks Cox ninth in customer satisfaction among internet service providers—the same as Frontier. (2) That's lower than average, but not by much.
We think Cox’s 30-day, no hassle money-back guarantee is solid. And we like its service. If you opt for self-installation, you can still get plenty of help online or by phone if needed. But if you use your own gear or technology isn’t your thing, $10/month will get you extra help, day or night, for things like malware removal, software installation and reconfiguration, and general troubleshooting.
T-Mobile is fairly new to providing home internet, but it has a solid track record of providing great service to its mobile customers. Both contract and non-contract customers see the best service in the industry, according to J.D. Power. (4)
We don’t like T-Mobile’s short 15-day money-back guarantee, which doesn’t give you much time for a test drive. (We much prefer Starry’s 30-day guarantee.) Even worse, your countdown starts when T-Mobile ships your 5G Gateway, not when it arrives. If there are any shipping delays or it takes you a day or two to get set up, you’ll run out of testing time fast.
