AT&T vs. Xfinity: Which Is Better for Your Home Internet Needs?

Is AT&T or Xfinity internet better?

AT&T and Xfinity are two of the biggest internet providers in the country. But which one is a better fit for your home? AT&T Fiber has faster download and upload speeds, better service terms and higher customer satisfaction than Xfinity, but it also has slightly higher pricing for comparable speeds. However, fiber internet from AT&T isn't available everywhere. That said, Xfinity is the better option in terms of availability, cheap internet and discounted bundle packages, at least until the introductory pricing period (typically one to two years) ends and standard pricing goes into effect. Price increases after a year are pretty standard when it comes to cable ISPs. However, customers can opt for Xfinity's five-year price guarantee in exchange for a higher monthly rate. But even if you're paying a higher monthly bill, you get to save money since this five-year price guarantee comes with free equipment and unlimited data .

With a combined 69% nationwide coverage, according to the FCC , and overlap in significant portions of each other's networks -- the odds of you having to choose internet service between AT&T and Xfinity are fairly high.

Xfinity's pricing and available speeds vary by location, so the provider's savings over AT&T Fiber will depend on where you live. If you sign up without the five-year price lock, select Xfinity markets may also have contract requirements for some of its plans, a 1.25 terabyte data cap (with potential overage fees) and a fee for opting to rent equipment . AT&T Fiber, on the other hand, has straightforward service terms: equipment is free, and there are no data caps or contracts.

It's safe to say that whichever option you choose, both providers are among the  best ISPs nationwide , so you really can't go wrong. In the most recent surveys from the  American Customer Satisfaction Index  and  J.D. Power Survey, AT&T and Xfinity finished with above-average ratings among major internet providers.

Which ISP better suits your home networking needs -- AT&T or Xfinity? Let's examine how they compare. 

AT&T vs. Xfinity plans, pricing and speeds

Below is an overview of AT&T Fiber and Xfinity internet plans. Xfinity speeds, pricing and service terms may vary depending on your region and chosen plan. I included only plan details for AT&T Fiber because if your choice comes down to Xfinity and AT&T's fixed wireless services, you should go with Xfinity.

Xfinity Internet plans (West region)

Xfinity's speed tiers are fairly consistent throughout all service areas, but pricing may vary slightly from one market to the next. The plans and pricing above reflect the West region. For example, the standard speed for Xfinity Connect More is 400Mbps for $40 a month in the West region, but the starting price can vary per month based on where you live. Just recently, Xfinity has also begun offering new customers a five-year price lock guarantee for its cable plans. If you choose to sign up for the five-year price lock, you can expect your monthly bill to increase by $10 to $15.

For the standard one-year price lock, rates on all plans, excluding the $300-per-month 10 gigabit plan, are set to increase in the second or third year of service, depending on your location and the plan you choose. Note that the exact price increases may vary depending on your address. Service terms also vary by location and plan as a data cap, equipment fee (if you choose to rent) and contract may apply.

Meanwhile, AT&T Fiber plans, speeds, and terms are more simpler and straightforward regardless of where in the country you live. The provider's 300, 500, and 1,000Mbps plans are available in all service areas, and many will also have the choice of 2,000 and 5,000Mbps plans. There is no set price increase after 12 months and unlike Xfinity's confusing equipment fees, AT&T offers free equipment for all plans.

Fees, data caps and other potential sticking points

AT&T is much clearer about service terms and doesn't offer any hidden fees—but only for its fiber plans. Let's take a closer look.

AT&T vs. Xfinity added fees

Like most providers, AT&T and Xfinity will charge you a bit extra each month if you don't enroll in autopay or paperless billing, but those fees are easy enough to dodge if you just select autopay when you sign up.

The equipment fees are another story. With AT&T, you won't need to pay extra to use AT&T's Wi-Fi gateway. That's included in the regular monthly fee. With Comcast Xfinity, the cost to rent the xFi Gateway is typically $15 to $25 per month (or $20 per month for the fiber 10Gbps plan), but it may be included at no extra charge with your plan. You can also bypass the fee, if there is one, by using your own compatible equipment .

AT&T vs. Xfinity data caps

As for data caps, AT&T doesn't enforce them with any of its fiber plans or its new 5G home internet service, AT&T Internet Air . AT&T's basic fixed wireless plan does enforce a data cap, however, kicking in at 350GB. You'll still get charged $10 for each additional 50GB of data you use, but AT&T caps the charge at $200 instead of $100. Be mindful of falling asleep during a Netflix binge, AT&T Fixed Wireless customers.

Xfinity, meanwhile, has a monthly data cap of 1.25TB for certain plans, but some locations may have no data cap at all. If you have a cap, going over may cost you $10 for every 50GB of excess data used, capped at $100. You can avoid data caps and these fees altogether if you sign up for Xfinity's five-year price lock.

To be fair, 1.25TB is a lot of data, but it's not unreasonable to think that a busy household would occasionally need more. For example, on my network, where I work from home, stream plenty of movies in 4K and live with a roommate who's online just as much as I am, we go through about 320GB of data here in the first nine days of the month. That puts us on pace to use just over 1TB by the end of the month.

If you live with, say, two roommates -- or with a whole family of internet users -- then data caps like those might be something you'd want to steer clear of if you could.

AT&T vs. Xfinity contracts

AT&T internet service, from fiber to fixed wireless, does not require a contract. However, select markets for Xfinity may require customers to sign a one to two-year agreement for some plans. Canceling or changing your service before the term agreement is up may result in early termination fees and losing the lower introductory rate on service.

AT&T vs. Xfinity installation costs

AT&T charges $99 for professional, in-home installation, but self-installation kits are available for some addresses and AT&T typically waives the cost for installation for new customers.

With Xfinity, professional installation typically costs $100, but you don't have to "qualify" for the self-installation option like you do with AT&T. However, the self-installation option will incur a one-time charge of $40.

AT&T vs. Xfinity coverage compared

A product of the nation's largest cable provider, Xfinity Internet, is available in select regions across 39 states and Washington, DC , covering about one-third of the entire population of the US. Most of that coverage is cable internet, but Xfinity has a small fiber network.

Areas where Xfinity's fiber internet service is available primarily include parts Indiana , Illinois and Michigan , though parts of Florida , Georgia and Tennessee may be serviceable for fiber as well.

As for AT&T, the telecom company offers home internet plans in 22 states, covering much of the South, Midwest and West Coast. Both providers may be available at your address in some parts of the country, including Atlanta , Chicago , Detroit , Houston , Memphis , Miami and San Francisco .

AT&T pegs the number of households with access to fiber at approximately 21 million, spanning over 100 metro areas. The company plans to expand fiber access to millions more homes by the end of 2025, including the rollout of its multigigabit plans .

For the rest, there's AT&T Internet Air and AT&T Fixed Wireless, which use a portable modem or satellite mounted at your home to receive a wireless signal, and AT&T Internet, which uses DSL copper cable connections in combination with the company's fiber infrastructure to deliver service to people's homes, albeit it at much slower speeds.

AT&T and Xfinity perks and promos

AT&T typically has limited-time offers for new fiber customers. Currently, AT&T Fiber customers can receive a VISA gift if they sign up online. You may receive a reward of $50, $100 or $150, depending on your chosen tier. AT&T also recently introduced it's All-Fi Pro package , which features additional perks like the Wi-Fi 7 gateway router. Additionally, wherever you are in the country, you'll have access to AT&T's nationwide network of 30,000 hotspots.

Xfinity is no slouch, either. Besides the five-year price lock offer for new customers, there are also a number of enticing promos upon signing for service. For those who are eligible for an Xfinity mobile line, you can shave off $10 to $30 a month from your internet bill for the first two years. Similar to many cable ISPs, Xfinity also gives you several options to bundle your internet with TV package or a mobile line , saving you $10 or more per month. Even better, Xfinity introduced StreamSaver last year, a new streaming service bundle combining Netflix, Peacock and Apple TV Plus for just $15 monthly. If you sign up for the gigabit and faster plans, Peacock Premium is already included with your service. Like AT&T, Xfinity has over 20 million hotspots nationwide, allowing you to stay connected to the internet wherever you are.

AT&T vs. Xfinity customer satisfaction scores

Everyone loves to hate their internet provider , so it's no surprise that customer satisfaction scores for the ISP industry aren't anything impressive. Still, AT&T and Xfinity are relatively strong performers here. AT&T remained at the top year-over-year with an 80 out of 100 from the latest American Customer Satisfaction Index . Xfinity's non-fiber score dropped a bit from 68 to 67 (bringing it just below the industry average of 68), but its fiber rating improved from 73 to 75. Not great, but not bad, either.

Meanwhile, AT&T grabbed the top spot in the North-Central and West regions (while Xfinity scored second-highest in both) in the most recent  J.D. Power US Residential Internet Service Provider Satisfaction Study for 2024. Notably, Xfinity just narrowly beat AT&T in the South with a score of 565 to AT&T's 564.

AT&T vs. Xfinity recap

If your options are AT&T's fixed wireless service and Xfinity, the latter will be the best choice for speed, value, and reliability nearly every time. On the other hand, if your address is serviceable for AT&T Fiber and Xfinity, you're likely to get a better value with more favorable service terms from AT&T Fiber than Xfinity. Given the choice of the two, Xfinity stands out for its broad availability and low introductory pricing, but AT&T Fiber has the advantage in virtually every other category.

AT&T vs. Xfinity FAQs

Which is better: AT&T or Xfinity?
