Worry free.  Our plans offer more data than most of our customers use.

Data usage basics

We measure data in gigabytes. That’s the amount of data you download
and upload from all the connected devices in your home each month.
Each of our plans comes with a monthly data allowance.

AT&T Internet Plans

You will receive an email notice the first time your usage exceeds the monthly data allowance. In subsequent months we will continue to send you alerts if your usage approaches or exceeds the amount of data included in your plan. If you exceed your monthly data plan a third time (bill cycle), and as our agreement provides, we’ll charge you $10 for each additional 50GB of data provided to you that month. The maximum overage charge is $100/month.

An unlimited allowance is also available for purchase as an optional bolt-on to your Internet service. If you purchase  DIRECTV or U-verse TV service bundled with your Internet service on a combined bill, you will receive an unlimited usage allowance with a $30 value at no additional charge as part of the bundle discount.

How much data do I need?

Some things to keep in mind as you estimate your data:

Downloading an HD movie is very data heavy, but sending a simple text email uses hardly any data at all.

Streaming video or music uses data that can add up quickly.

Monitor your use regularly if you use a lot of data.

Going over your data plan may cause extra charges, so if you use a lot of data, you'll want to check it regularly.

How we'll help

  • We'll send you email alerts when your usage reaches 65%, 90%, and 100% of your monthly data allowance. We'll also send you an email the first time your usage exceeds the data plan. (Charges apply the third time you exceed your plan threshold.)
  • We provide a data calculator to help you estimate your monthly data usage, so you can choose a plan that fits your needs.
  • We display your current usage in myAT&T, our online account management site, or in the myAT&T app on your mobile device.
  • We give tools and tips to secure your network, guard against viruses and intruders, and use parental controls.
  • We offer a variety of data plans to fit the needs of customers with high data usage. If you routinely exceed your data limit, you may want to consider a different data plan.


You can also log in to your account on myAT&T to:

  • Check your current usage within 24 hours.
  • See data usage levels for each day.
  • Data usage summarized by month.


Or check your usage on your mobile device with the myAT&T app.

Take steps to control your data usage

Save your data by controlling your activity at home and by keeping the bad guys off your network.

Secure your connection

One of the most important things you can do to manage your usage is to secure your network to keep others from using it without your permission.

Defend your devices

Don’t let your connected devices become zombies for hackers, spammers, and virus spreaders. Use our free AT&T Internet Security Suite powered by McAfee®.

Take control

Controlling online time and activities for each member of your household is a great way to help you avoid data overages. 

Understand Internet usage

Understanding how much data you use can help you avoid overages. Activities like online gaming, streaming movies and TV shows, and music downloads contribute to your data use. It’s not how long you’re on the Internet but what you do while you’re there that determines how much data you use.
