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
