AT&T’s fiber-optic network is great for speed and reliability, but Xfinity has lower-priced plans that may appeal to some.

AT&T and Comcast Xfinity are two huge names in the telecommunications industry. Which one offers the best internet service?

AT&T Internet offers a higher quality network with great speeds, decent prices, and no data caps. But Xfinity Internet has more plan options and availability, making it appealing to those who want cheaper, lower-speed plans.

Let's get into the details of pricing, download speeds, and data caps to find the best home internet service for you.

AT&T vs. Xfinity: Prices

Winner: Comcast Xfinity Internet

Xfinity has more plans to choose from, but we do like the simplicity of AT&T’s no-contract plans.

We’ll skip the long-winded intro here and just jump right into the plans so that you can make up your own mind. Let’s begin with AT&T Internet.

As you can see, AT&T Internet’s plans have a big range of speeds, from 300 Mbps to 5,000 Mbps! 

We think AT&T’s lower-range plans, like the Internet 300 and 500, are the best options for most people. You get plenty of speed for streaming, browsing, gaming, and working from home, but you’re not paying through the nose for it.

One thing we really appreciate about AT&T’s plans is the simplicity: there are five options for fiber internet and two options for DSL internet. Also, the company doesn’t require annual contracts. This is not the case for Comcast’s Xfinity internet service.

Xfinity requires 1-2 year contracts, and it has three separate price ranges, depending on where you live. There’s a Northeast, Central, and West region. We’ll show you all of the prices in three charts below so that you know what’s available.

But, honestly, the easiest way to see Xfinity plans in your area is to use this zip code tool.

° For 36 months. No term contract. Includes $10/mo automatic payments and paperless billing discount. Taxes and equipment not included. Prices may vary by location.

You can see that Xfinity Internet has a much wider range of prices and speeds than AT&T. Its cheapest plan is far cheaper than its priciest option. It offers speeds from 200 Mbps all the way up to 1,200 Mbps!

One thing to remember is that not all of these plans will be available in every part of the Northeast.

And, to be honest, it’s not really clear where Xfinity’s different price regions begin and end (somehow Minneapolis, Minnesota is in the Western instead of the Central zone?).

Ok, let’s move on to the Central zone plans and prices.

Yes, that’s a 1,200 Mbps plan! While that’s probably more internet speed than you’ll ever need (at least until we all live full-time in the metaverse), it’s pretty cool to see.

In fact, we’re rather impressed overall with Xfinity’s Central zone offerings.

$55 a month for 400 Mbps? Not bad. $85 for 1,200 Mbps? That’s one of the reasons that Xfinity Internet gets the “Best Value” badge in our lineup of the best ISPs.

Finally, let’s turn to the Western zone.

These Western plans look similar to the Northeastern plans. There are a lot of options in terms of both price and speed, which means there’s something for every kind of family. 

All of these plans will get you access to millions of Xfinity Wi-Fi hotspots across the globe. So you don’t have to pay $10 an hour for an internet connection while you wait for your connection at the airport. Nice.

These Xfinity internet plans also share some downsides, like a 1.2 TB data cap (more on that below) and installation and early termination fees (boo!).

Xfinity does offer unlimited data and high download speeds with its Gigabit X2 plan, but sadly, this plan is only available in Seattle. 

Phew! That was a lot of internet plans to cover. Take a deep breath … ok, now let’s talk about availability because what good is all this info about plans if you live outside of the service area?

Xfinity vs. AT&T Fiber: Availability

Xfinity and AT&T have a similar coverage area. Both have a heavy presence in midwestern states, like Illinois, Michigan, Ohio, and Missouri. Both have a sizable presence in California and Southern states like Georgia and Louisiana.

Xfinity’s coverage eclipses AT&T’s certain parts of the West, like Utah, Colorado, New Mexico, Oregon, and Washington. It also covers much of the Northeast, where AT&T internet doesn’t really exist at all. Meanwhile, AT&T’s availability is stronger in much of the South and Great Plains region.

Xfinity vs. AT&T: Internet, TV, and phone bundles

Winner: Both

Both companies offer stellar deals on TV, phone, and internet bundles

You probably already know that AT&T isn’t just an internet provider—it's one of the largest mobile phone carriers in the country.

Xfinity also has the holy trifecta of services: internet, cable TV, and mobile

So, which company offers better deals? It depends on the download speeds and channels you want. We'll help by listing some of our favorite bundles from each of them, beginning with Xfinity.

Xfinity vs. AT&T: Internet speed and data caps

Winner: Both

AT&T’s network is more reliable and won’t cap your data usage, but Xfinity Internet offers higher download speeds in certain areas.

Xfinity and AT&T make it on our list of the fastest ISPs, but these two companies aren’t exactly fast in the same way.

Xfinity has some of the fastest download speeds available. In certain areas, it offers an unreal 3,000 Mbps plan! That’s basically warp speed.

But one thing that Xfinity lacks is a robust fiber optic network. Although it has a few locations where fiber internet is available, it can’t really compete with AT&T. That means AT&T customers will usually see much more reliable and significantly faster upload speeds

Faster upload speeds mean you’ll have less lag while gaming, smoother video when Zooming, and an overall easier time using the web.

In short, AT&T’s network will probably be better for most users, offering more reliable speeds and performance. 

AT&T vs. Xfinity: Data caps

One of the biggest downsides to Xfinity Internet is the 1.2 TB data cap that comes with every plan.

While the average monthly internet data usage for US households is about 433 GB a month, there are still plenty of gamers, remote workers, and large families that will exceed that amount and surpass Xfinity’s data cap.

Xfinity will charge you $10 for every 50 GB of data you use above 1.2 TB. You can avoid the overage fee by paying a clean $30 a month for unlimited data.

But why pay an extra $30 when you could just go with AT&T fiber, which has no data cap?

In other words, those who use the internet a lot might have more peace of mind with AT&T than Xfinity.

AT&T vs. Xfinity: Customer service

Winner: AT&T tops the charts, but Xfinity isn’t far behind

Picking an internet provider based on its customer service is kind of like choosing an airline based on the prices of its in-flight meals. You’re probably never going to be fully satisfied with what you get, and even if you are, it’s not the most important factor.

That said, there is something really nice about knowing that a real human will pick up the phone and help you when your modem isn’t working.

So, who’s more likely to make it easy on you, AT&T or Xfinity?

The most recent telecommunications report from the American Customer Satisfaction Index puts AT&T Fiber first among fiber internet providers. Xfinity sits in 5th place out of all non-fiber internet providers.

So AT&T customers will have a better experience with receiving help, and Xfinity customers might have to be a little more patient.

What’s the final verdict? We think that AT&T offers a better overall performance, but Xfinity may still be best for those who want a cheaper plan.

Here’s a quick recap of who won each section of this AT&T vs. Xfinity internet review.

  • Price: Xfinity. Xfinity offers a wider range of plans than AT&T, including great affordable options.
  • Internet speed: Both. AT&T’s mostly fiber network gives you more reliability and better upload speeds, even if it isn’t always as fast as Xfinity’s top-tier plans. But if fiber internet isn't available in your area, Xfinity is the best cable internet provider because of its high-speed internet.
  • Data caps: AT&T. Xfinity’s 1.2 TB data cap is a real bummer. AT&T doesn't have any data caps.
  • Customer service: AT&T. Both companies offer good customer service, but AT&T is at the top of the charts.

AT&T vs. Xfinity Review Methodology

To decide what was better between AT&T Internet and Xfinity Internet, we weighed the following categories:

Internet plans and pricing

  • We looked at the plan offerings from both AT&T and Xfinity to determine which offered better value. Our findings revealed that AT&T offered much more firepower in terms of download speeds, upload speeds, and data caps but was less available and more expensive than Xfinity internet plans. Xfinity plans, on the other hand, make more sense for folks looking for more affordable internet plans.

Availability

  • Looking at coverage maps and analyzing coverage data from third-party sources, it was clear that Xfinity had more availability than AT&T Internet.

Data caps

  • Through analyzing the different data plans offered by Xfinity and AT&T, we found that Xfinity does enforce data caps, and AT&T does not. This was a major point in favor of AT&T Internet.

Data speeds and performance

  • To get an accurate reading on speed tests, we gleaned information from company websites (advertised speeds), and compared data speeds with our proprietary data and information we could glean from third-party sources, including leveraging social media websites like Reddit.
