One of AT&T’s strongest features is that it offers a variety of plans with different prices, speeds, and connection types. Xfinity also has multiple plans, but they’re limited to cable and fiber internet; AT&T, meanwhile, offers fixed wireless, IPBB, and 5G home internet on top of its fiber service. Xfinity, however, generally offers better bundle deals than AT&T (more on that below). Both providers excel in nationwide coverage for their non-fiber plans. If affordability is your top priority, then you’ll be relieved that AT&T and Xfinity’s non-fiber plans are budget-friendly and more accessible than their fiber plans.

Xfinity Internet Offers the Best Bundles

AT&T offers the most affordable bundles, but its offerings only include internet and phone services. On the other hand, Xfinity offers bundles featuring internet, phone, home security, and TV service for prices starting at $45 per month. Overall, Xfinity is the better provider if you’re looking to bundle numerous home services.

AT&T Internet Features Lower Fees Than Xfinity

Both AT&T and Xfinity Offer Free Installation

AT&T offers self-installation, which lets you skip the $99 professional installation fee. Xfinity also offers free self-installation, as well as Self-Install Plus, which includes technician guidance for a one-time fee of $39.99. If you want a fully professional installation, Xfinity charges $100. Xfinity, like AT&T, commonly waives the installation fees for first-time subscribers.

AT&T Has More Generous Data Caps

AT&T has data caps only on its IPBB and fixed wireless plans, which means most of its internet plans come without limits. Xfinity, meanwhile, imposes a 1.2 TB data cap on most plans, but you can pay extra for unlimited data.

AT&T Surpasses Xfinity in Customer Satisfaction

Based on J.D. Power awards and the American Customer Satisfaction Index, AT&T has a better customer-service reputation than Xfinity.
