AT&T data plans

We're all using an increasing amount of data, or bandwidth. AT&T has experienced a dramatic increase in the amount of data that is sent and received over its wireline broadband networks. This dramatic increase is driven primarily by a small fraction of our customers. Most AT&T High Speed Internet users will not experience any change as a result of this updated policy, because our new data plans offer far more bandwidth than the average person ever uses. We’ll notify you by email or letter several times before you incur any charges for additional data.

What happens if you exceed your data plan?
You’ll receive a notice the first time your usage exceeds the data plan. We’ll 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, we'll charge you $10 for each additional 50GB of data provided to you that month. You'll be charged $10 for every incremental 50GB of usage beyond your plan.
Will spending a lot of time on the Internet cause me to exceed my data plan?
Time is not the determining factor; it’s the activity that matters. For example, you could spend several hours reading emails and use less than 1GB of data. On the other hand, you could spend 30 minutes downloading a movie and use 2GB of data. Keep in mind, it’s what you’re doing on the Internet, not how long you do it, that determines the amount of data you use.
