AT&T vs. Xfinity: Which Is the Best Internet Service Provider?

What can we say? We love fiber internet, so we think AT&T is the best option in this internet service provider (ISP) duel. AT&T’s fiber plans are fast and affordable, plus you get unlimited data. Xfinity still has some nice options, though, including lower-tier plans that won’t break the bank. Also, Xfinity is much more widely available than AT&T, so it’s a solid Plan B if you can’t get fiber in your area.

Plans and pricing: AT&T vs. Xfinity

AT&T plans and pricing

It’s not easy to find fiber internet below $50 per month, but AT&T gives you just that. AT&T’s three fiber-optic internet packages all come at an excellent price. Even better, you get upload speeds that are just as fast as download speeds, making these plans perfect for upload-heavy activities like Zoom and hosting livestreams on Twitch.

AT&T’s fixed wireless package is useful if you live in a rural area and want an alternative to satellite internet. It’s not as fast as the fiber plans, but it promises a minimum of 10 Mbps and gives you more data than you would get from expensive satellite plans.

Best AT&T deals and promotions

The best deal from AT&T is Fiber Internet 300. At just $35 per month, it’s a ridiculously cheap plan for what you get—an extremely reliable fiber-optic connection and robust speeds fit for relatively large households and high-demand internet users.

The best promotion from AT&T is the chance to get a Prepaid Visa Gift Card when you sign up online for a qualifying internet plan. AT&T regularly offers promotions and discounts like these so make sure to scope out our best internet deals page for the latest updates.

Xfinity plans and pricing

*For the first 12 months with a 1-year agreement.

**With a 2-year agreement.

Xfinity’s prices and plans vary slightly depending on the region you’re in. But wherever you are, you’ll get fast speeds and a range of price options. You won’t get the excellent upload speeds of AT&T’s fiber plans, but you can still get great performance and save some money by springing for one of the cheaper plans.

But if you want some serious speed, Xfinity might cost you more. Its gigabit plan costs more than AT&T’s similar plan, and generally you could end up paying more for faster speeds on Xfinity.

And yes, Xfinity gets bragging rights for having the 2,000 Mbps Gigabit Pro plan—tying with Google Fiber’s 2 Gig plan for the fastest home internet plan in America. But, well, it also costs nearly $300 a month, plus a massive activation and installation fee, and we’re not even sure where you can get it. Availability is highly limited.

Best Xfinity deals and promotions

The best deal from Xfinity is Performance Pro Plus. It costs $50 a month (or even less in some areas), which is a great price for 200 Mbps speeds—enough to support a household of four or five heavy internet users.

The best promotion from Xfinity right now is the chance for professional educators to get a $100 Visa prepaid card when they sign up for a qualifying Xfinity internet plan. You can get the deal as a new customer if you offer proof that you’re a teacher, college professor, school or university administrator or faculty staff. The offer expires January 31, 2022.

Extra fees: AT&T vs. Xfinity

Data as of 10/20/21. Offers and availability may vary by location and are subject to change.

Most internet providers tack extra fees onto your bill. You’ll get charged extra for exceeding your data cap or for canceling your contract early, but both AT&T and Xfinity give you options for waiving fees or reducing them. If you’re late on payments, each has a grace period where you can have extra time to cover your bill before your service is shut off.

Customer ratings: AT&T vs. Xfinity

In our annual customer satisfaction survey, AT&T pulls in ahead of Xfinity in all categories. While Xfinity mostly gets below-average scores, AT&T gets high rankings for speed, reliability, and overall performance.

AT&T ranks especially well for speed, with 84% of AT&T customers reporting in our survey that their internet speeds usually or always meet their household’s needs. The same percentage also reported sometimes experiencing slowdowns on their network connection, but that’s fairly common for many internet providers. Meanwhile just 35% of AT&T customers reported experiencing unexpected price hikes or hidden fees.

Xfinity doesn’t rank as high in the happy-customer department, but if you look closer at the data, Xfinity doesn’t look so bad. While it got a below-average speed rating, 87% of users said their speeds usually or always meet the needs of their house—which is actually better than AT&T. And though fewer AT&T customers dealt with price hikes and hidden fees, just 42% of Xfinity’s customers had the same issues, which is pretty much average for the providers we studied.

Best TV and internet bundles

†For the first 24 months with a 2-year agreement.

Since Xfinity is a cable provider, we’re not surprised that it has low prices and lots of options for bundle packages. We think the SELECT+ plan is pretty groovy because it starts at less than $100 per month, gives you an excellent internet speed, and comes with 20 hours of DVR storage.

Both of these providers also let you do triple-play bundles that include internet, TV, and landline phone service if you need it.

AT&T used to offer bundle packages with DIRECTV, but they are no longer available. DIRECTV still has lots of TV deals, but you’ll need to order them separately from AT&T internet plans.

Can you bundle a mobile phone plan with AT&T or Xfinity?

You can get deals from Xfinity by bundling an internet package with a cell phone plan through Xfinity’s wireless branch, Xfinity Mobile.

Xfinity Mobile is an MVNO (mobile virtual network operator) and Xfinity offers a lot of incentives for internet customers to sign up. Depending on what’s available at the time, you can get discounts on your monthly bill, VISA prepaid gift cards, or even discounts on new phones.

Take a look at our Best Internet Deals page for the latest Xfinity Mobile bargains.

AT&T is of course also known for its many wireless offerings, including nationwide 5G service. But you have to order a cell phone plan separately from an internet package, and each comes at their respective standard prices.

Internet connection types: AT&T vs. Xfinity

AT&T plans are mostly fiber. A fiber connection gives you excellent speeds for both uploads and downloads, making this internet type ideal for high-bandwidth users who spend a lot of time streaming, gaming, or attending Zoom meetings (or doing all of the above simultaneously). The one disadvantage of fiber is that it’s not as commonly available as other internet types.

AT&T also has a fixed wireless internet package. Fixed wireless internet is geared towards customers who live in places with limited internet infrastructure. It’s especially useful for rural areas where satellite internet is the only other option since you can get faster speeds and more data over a fixed wireless connection.

Aside from its 2,000 Mbps Gigabit Pro plan, Xfinity primarily delivers cable internet. Cable is fast and reliable, much like fiber, although it can’t hit the same top speeds for uploading that fiber can. Cable is also more widely available than fiber, making it the go-to option for most internet users who need high-speed service.

Data caps: AT&T vs. Xfinity

AT&T’s fiber internet plans all come with unlimited data, so you can enjoy smooth connections and fast speeds without worries of exceeding a monthly limit. Non-fiber plans with speeds below 75 Mbps have a 1 TB monthly cap, which is still plenty. For rural customers, AT&T’s fixed wireless internet plan does have a data cap of 350 GB. If you go over your data for the month, you’ll be billed $10 for every 50 GB of data you use.

Xfinity packages all come with 1.2 TB caps. That includes the Gigabit and Gigabit Pro plans, which is kind of a bummer since a lot of providers offer unlimited data with gigabit plans. You’ll need to pay $10 for every 50 GB that exceeds your cap. Or you can spring for unlimited data for an extra $30 per month.

Contracts: AT&T vs. Xfinity

AT&T doesn’t require an annual contract when you sign up—its service runs month to month, and you can cancel any time without paying a penalty fee.

On most of its plans, Xfinity lets you choose between signing up for an annual term agreement or opting for a no-contract option. If you decide to skip the contract, you’ll need to pay $10 more per month. The Gigabit and Gigabit Pro plans have two-year contracts, while most other plans have one-year contracts.

Installation: AT&T vs. Xfinity

AT&T and Xfinity both have affordable options for installation. AT&T’s professional installation officially costs $99, but the provider will waive the fee if you put in an order online. If you’re ordering over the phone, you can probably haggle with customer service to do away with the installation fee.

Xfinity will mail you a self-installation kit at no extra cost. But if you pay $29.99, you can have it sent to you in priority shipping, so it will arrive after 1–2 business days instead of 3–5. You can also pay $39.99 for the “Self Install Plus” option, in which a professional technician will come over with your self-installation kit to set it all up and make sure it’s working.

Availability: AT&T vs. Xfinity

AT&T and Xfinity are both major internet providers in the US, with huge footprints across the country. With a network that can cover as many as 148 million people, AT&T is available mostly in California, Texas, the South, and the Midwest. Xfinity has a big presence in the East Coast, South, and Midwest, reaching potentially around 130 million people.

Final call: AT&T vs. Xfinity

AT&T is a perfect choice for customers who want fast speeds, fair prices, and fabulous fiber-optic performance. Xfinity, a cable provider, is also excellent when it comes to speed—boasting a 2,000 Mbps plan. And it has a much wider coverage area and plenty of options for cheap internet, but you’ll generally pay more money for the faster plans than you would for AT&T.
