ATT is bad for whatever reason at handling large groups of people. Every OSU football game I go to I get 100% signal strength yet cannot access data EVER. I wonder if they shut data off at those towers during games to leave bandwidth open for voice/text. When I do large conventions in Vegas, same problem.
Same problems in Austin when you have ACL fest. No data. I only have EDGE and getting data is not a guarantee for me even when there is no huge event.
And switching isn't something I want to do cause then I'd have to buy more minutes. Too many people with AT&T.
