I'm so not happy learning about AT&T increasing my unlimited data plan another $5 per month. We just had a $5 per month increase last year! In that first increase AT&T popped off about how this was their first increase in 7 years. Apparently now it's every year! I've had AT&T for a very long time, but now I think it's time to find another carrier.
I agree, I for one have decided against T-Mobile for me personally, but will be giving up on my old UDP and moving to the family plan unlimited option. I don't get as much of a discount on that plan, and if I leave Directv I will lose it but at this point it will be cheaper overall. Of course cheaper is still way too much, but not much you can do about it.
