Xfinity offers plans in the Northeast, Central/Southern and Western regions of the country. AT&T is mainly available in the Central and Southern regions of the U.S.

Xfinity charges $14/mo. for its xFi Gateway device. You also have the option with Xfinity to buy your own equipment. There is a $40 professional installation free, but you also have the option of self-installation. 

Data caps

Xfinity internet plans come with a 1.2 TB/mo. data cap. Exceeding your limit will result in added fees similar to AT&T’s, or you can sign up for unlimited data for an extra $30/mo.

AT&T Fiber customers, on the other hand, can enjoy unlimited data with any plan.

Contracts

You won’t have to sign a contract with AT&T internet plans. Term agreements for Xfinity are less black and white. Some regions, such as the West and Northeast, may not require a contract to get the lowest pricing on select plans. The Central region may require a one or two-year contract to get the lowest monthly pricing. If you have a contract and cancel before it expires, you will be charged an early termination fee. The termination fee will be prorated based on the internet plan you choose.

Compared to AT&T, Xfinity internet has a lower starting price, but if you’re looking for top speeds, AT&T Fiber is likely to be the cheaper option as their higher-tiered plans are likely to come at a lower monthly price than similar Xfinity plans. Additionally, Xfinity increases its prices after the first 12 months, which means AT&T plans are often cheaper long-term, even if its starting price is higher than Xfinity’s.

AT&T and Xfinity both have bundle options if you’re looking to simply your monthly bill.

If you are trying to decide between AT&T or Xfinity services for your home, looking at their plans side by side is a good idea. AT&T Fiber is the best value overall; however, if AT&T isn’t available in your area, you will want to go with Xfinity instead.
