AT&T Internet vs. Xfinity Performance Overview

AT&T Internet is a nationwide telecom provider. They offer DSL and fiber Internet, as well as TV and phone plans.

Xfinity is the largest Internet provider in the country, offering WiFi, digital phone services, and TV services.

AT&T offers two types of internet: fiber and DSL. What you can get depends on your location, since AT&T’s fiber service is currently only available in select large metro areas. AT&T also offers a wide range of bundle options with its U-verse TV or DIRECTV service, as well as landline and wireless phone service.

Xfinity from Comcast is the largest cable internet provider in the United States, with service available to over 111 million people across 39 states. Xfinity predominantly offers cable internet service, but the provider has a small fiber serviceable area that should continue to expand through 2020. Just like AT&T, Xfinity customers can also bundle their internet with TV and/or phone service.

AT&T Internet

The service has been reliably fast and smooth. My only complaint is that the internet isn't unlimited, unless you choose the package to have TV service which is not desired for myself.

AT&T Internet

This service is very reliable though I am disappointed that the max download speed averages 10.8 Mbps in my area. I would love to see the 25 Mbps they advertise for Baxley. No one I know has ever seen that. In rural America we have very limited choices, so I suppose I should be grateful that we have an advertised 12 Mbps plan from AT&T.

XFINITY from Comcast

First time Xfinity subscriber. Exceeded my expectations. I can honestly say I was very impressed with all aspects of Xfinity. I just purchased a home in Delray Beach FL. From the initial appointment call to complete installation, Xfinity exceeded my expectations. Very impressed with the Tech. The tech arrived early. He introduced himself and ask me about my expectations. He explained what he was going to do and would have me watching NFL football today. Walked me through the setup and all options of the remote. I ordered cable and internet. I will say the internet service is faster than others. Very impressed with Xfinity.

XFINITY from Comcast

I have Xfinity for about 6 years. So far, the service has been really reliable and the speed is really great. The only issue I have with it is the bill and how it's capped. I had to upgrade to have unlimited but so far it is really reliable and great.

AT&T Internet
Contracts, Equipment Fees & Fine Print

Most of AT&T’s plans require a minimum 1-year agreement.

They do have some prepaid plan options, but these plans don’t offer the same type of promotional savings available with a contract plan. If you end your contract early, be prepared to pay up to $15/month for each remaining month on your contract (up to $180). Equipment fees are included in AT&T packages.

Xfinity
Contracts, Equipment Fees & Fine Print

Xfinity gives you the option to go contract-free for around $10/month extra.

If you do opt for the contract savings, keep in mind their contracts can be as long as 24 months. Early termination fees vary, but you will need to pay for each remaining month in your contract - so this could add up. Xfinity’s equipment fees are not included in the cost of the package and currently start at $11/month for basic equipment.

AT&T Internet Data Caps

Most of AT&T’s plans come with a 1 TB data cap per month, with the exception of their Internet 1000 plan which comes with unlimited data. If you reach your monthly limit you can pay $10 for every 50GB of additional data.

Xfinity Data Caps

All of Xfinity’s plans come with a 1 TB data cap, including their Gigabit and Gigabit Pro plans. Just like AT&T, you can pay $10 for each additional 50 GB of data if you exceed your monthly limit. Xfinity also provides the option to pay $50/month for unlimited data with any plan.

  • Do AT&T and Xfinity have unlimited data?

    AT&T offers unlimited data with its Internet 1000 plan, but every other plan comes with a 1 terabyte (TB) limit per month.
