Data allowances and usage info
Data usage is all the data you receive (download) or send (upload). This applies no matter how you access the internet from your home network. It may be through a wired or Wi-Fi® connection. You can estimate future data usage with our internet data calculator.
Usage includes tasks like software updates, email use, and social media posts. Individual usage varies based on the apps you use and the content you access. For example, usage for email apps may be more than what the data calculator shows if your emails have large files attached.
FYI: If you have DSL, we may not be able to measure your data use because of system limitations. In that case, you won’t be able to use the data tracker to see how much data you’re using. Don’t worry though, if this happens, we won’t charge you for usage over your limit.

Data usage updates
We pull usage data from the network every four hours for most accounts. It is at 15-minute increments if you routinely use more data. You may not be able to view usage info for the first day of a new bill period until later on in the day. Usage display shows time in terms of GMT (Greenwich Mean Time) time zone, which is behind U.S. time zones.
Good to know: Trained and specialized AT&T lab engineers check the accuracy of our system on a regular basis.
Fifty thousand emails with no file attached is about 1GB. The same goes for watching an 80-minute movie in standard definition (SD). Watching 20 minutes of a movie in high definition (HD) also equals about 1GB.
FYI: The types of activities you do affect your usage more than the time you spend online. For example, data-rich activities like streaming video may use more data than sending emails.
