Some things to keep in mind as you estimate your data:
Downloading an HD movie is very data heavy, while sending a simple text email uses hardly any data at all.
Streaming video or music uses data that can add up quickly.
Going over your data plan may cause extra charges, so if you use a lot of data, you'll want to check it regularly.
You can also sign in to your account on myAT&T to:
Save your data by controlling your activity at home and by keeping the bad guys off your network.
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.
Don’t let hackers, spammers, or virus spreaders target your connected devices.
Stay protected with the free AT&T INTERNET Security Suite powered by McAfee®.
Don’t want to go over your data limit? If you have AT&T Internet, AT&T FIBER, or DSL, you can use the Parental Controls feature of the AT&T Internet Security Suite powered by McAfee. Not available for Fixed Wireless Internet.
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.
