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 lets you install your own equipment for a $35 activation fee.
If you want professional installation, the fee is typically $99 - though it’s waived with qualifying Triple Play packages.
Unlike AT&T, Xfinity doesn’t charge an activation fee for DIY installation.
Their professional installation also costs less than AT&T’s, with prices ranging from $60-90 depending on your package and equipment.
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 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.
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.
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.

Absolutely fantastic! Tech came out to help install and, due to the wiring in our apt, it took a while to find the correct outlets. But he was so patient and helpful and kind, really going above and beyond to make sure things got set up so I could have the level of coverage needed to qualify for work from home. Truly amazing guy, I honestly can't speak highly enough of him. He kept trying long after I suspect most would have given up. Huge THANK YOU to AT&T for the coverage at the right price (literally half the price of the competitor in this area), and more importantly for having such an amazing guy on your team. Thank you.

The service was outstanding. I called on Sunday and they put me on a schedule for Wednesday. The technician came on time with all protective gear: mask, shoe cover. He was very professional, promptly explained everything that I did not have a question to ask. We have our hi-speed internet in 1 hour. This is great teamwork. Thank you and your customer service team.

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 customer service rep is the best customer rep that I’ve talked to. My first time getting an internet connection couldn’t have been better. I was nervous at first but their customer service rep made it so much easier for me to understand how and what I should do to get it done. Love the work, Xfinity.
