Home internet data usage

Explore our plans, learn how to check your usage, and more.

Data usage includes all data sent and received when you use your home internet. This data is measured in gigabytes.

Our internet plans

All plans come with a data allowance for each bill period. You’ll get an email alert when you use 65%, 90%, and 100% of your monthly data allowance. We’ll also email you the first time you go over your data limit.

Charges apply the third time you go over your data limit. There’s a $10 charge for each additional 50GB of data. The maximum overage charge for:

  • AT&T Internet® is $100 a month
  • DSL and Fixed Wireless Internet is $200 a month

See the Customer Service Agreement for more details

 

Unlimited data usage

Have AT&T Internet®? You can upgrade to unlimited data if you have:

  • Internet 100 or higher
  • The unlimited usage allowance option for $30 month

Manage your data use

Protect your connection

Secure your network. This is one of the easiest ways to prevent others from using your data.

Defend your devices

Don’t let others target your connected devices. Stay protected with AT&T Internet Security Suite powered by McAfee.

Control family use

Use Smart Home Manager with AT&T Internet and some Wi-Fi gateways. Create profiles, set time limits, or pause internet.

Know your data use

Your online activity determines how much data you use. Activities like gaming and streaming use a lot of data.
