Seems that ATT and Verizon should have prepared better. I have no sympathy for them since they have been collecting billions over the past 5 years on services that cost them money.
Yeah, well they're in the business to make money and basic supply and demand says they can and will charge heavy users more than light users. This is not socialism. They are not in business to provide you free an unlimited service to your heart's content. But to your point, yeah, I guess they aren't charging enough if they are running into capacity issues.
As for the planning, the capital outlays are huge and take time, not to mention you have licensing rights and leases in place to locate your towers. Poor planning in the other direction puts them out of business and less providers is rarely a good thing for consumers.
