Data Plans - prices are getting ridiculous

AT&T - can you PLEASE consider offering your customers an unlimited data plan. Just about everyone has a smartphone now and a data plan is required. Yes, you do have the shared plans, BUT when you have several phones, tablets, AND teenagers - that doesn't work..... I, along with so many others, have been a longtime and faithful customer and hate to consider leaving. However, my wallet is about to over rule my faithfulness.

I'm trying to stay loyal - but the prices are killing me....

PLEASE HELP!!!!!
