Although both the providers offer the fastest internet plans, overall AT&T offers higher speeds with unlimited data. AT&T provides speeds ranging from 75 Mbps up to 5000 Mbps. You can get symmetrical download and upload speeds with AT&T fiber internet plans.

On the other hand, Xfinity offers higher download speeds in some areas. You can get speeds up to 3000 Mbps in certain areas. The unfortunate thing about AT&T is that it lacks a fiber-optic network and experiences slow speeds during rush hours.

Data Caps

Xfinity enforces data caps on all of its plans. However, the provider has delayed the data caps for another year in the Northeast region. This means that people in the Northeast can enjoy Xfinity’s plans with unlimited data. For regions with data caps, Xfinity charges an extra $10 for every 50 GB of data after you exceed your set data limit. You can avoid this fee by paying $30 for unlimited data for the rest of the month.

On the other hand, AT&T doesn’t enforce data caps on any of its fiber internet plans. But if you live in rural areas and are subscribed to AT&T fixed wireless internet, you have to pay attention to the data usage. AT&T enforces data caps on its fixed wireless internet plan.


AT&T is one of the no-contract internet providers. Hence, you can cancel its service at any given moment without worrying about an ETF.

Xfinity, on the other hand, gives you two options. You can either go for the contact option or the no-contract option. However, you need to pay an extra $10 for the latter choice. All the Xfinity plans come with a 1-year contract except for Gigabit and Gigabit Pro, which have a 2-year contract.

Customer Service

Looking at the statistics, we can safely assume that both providers have decent customer service.


Overall, AT&T is a much more reliable internet provider with a better performance. However, Xfinity is also an ideal option with its cheap internet plans. The choice depends on your requirements. AT&T is an ideal option for those who prefer fiber internet service, fast speeds, and uninterrupted connectivity. Xfinity is also an ideal high-speed internet option with wide coverage.
