How will AT&T help me to monitor my usage?  
AT&T will provide a website with two options to assist customers in managing their High Speed Internet usage.   
First, AT&T will provide a personal usage report at 
www.MyUsage.att.com  where customers can view how much actual data they have used in a given  month from the January 2011 bill cycle to the most recent billing  cycle.  To protect confidential customer information, this site is  password-protected.  The login process requires your Internet access  login and password.  The login is your AT&T primary account email  address (e.g., 
John_smith@att.net).  The password is the same password  used to access your att.net homepage and primary email account.
  
 AT&T initially will report usage data on a weekly basis.  When a  customer uses 70% of their monthly usage allowance, we will supplement  their personal usage report on a daily basis.  A customer's usage will  be posted on the website within 1 - 4 days after it is collected.
