January Data Access 1,523,863 this appears to be the cause of the problem. See this number I have been warned that Im in the top 5% of all data usage consumers and will now be warned that my access speed will be down graded when I reach a level I guess that is unacceptable to AT&T !  Wow love how they can rewrite the playbook on us and say thanks for using the service but we are going have to cut back on the quality now. AMAZING ! 

Here was my lovely warning 

For the current billing cycle, your data usage indicates you could be affected by this change. Here’s how it works: 

Smartphone customers with unlimited data plans may experience reduced speeds once their usage in a billing cycle reaches the level that puts them among the top 5 percent of heaviest data users. These customers can still use unlimited data and their speeds will be restored with the start of the next billing cycle. 

We’re writing because you are in the top 5 percent of heaviest data users for this billing cycle. Because we recognize that data usage can change from month to month, you will not see reduced speeds this billing cycle. 

Beginning with your next billing cycle, we’ll send you a text message if you are approaching the top 5 percent of heaviest data users. We’ll also send you a second text message if you cross into the top 5 percent of heaviest users, at which point you may see reduced speeds for the rest of the month.

Has anyone else gotten this message ? Im just wondering what is your data usage ? Is this really a high number ? I work on my phone daily. After all its a SMARTPHONE !
