The fact that it just is less profitable for AT&T to cover a large number of people at once means that unless we complain and make it a pain for them to keep providing poor service they will continue to do so.
If it is less profitable for them, perhaps the solution is to make it more profitable. Maybe you should offer to pay more each month!
If you really want to make it a pain for them, vote with your wallet. Nothing else matters very much. You know: "Money talks, ******** walks."
