Interesting read why the data is not measured properly and the customers get overcharged. I don't agree that a software fix (put software on phones to acknowledge data received, and thus improve the one digit % error margin) would solve this problem. It would be more beneficial to have real competition among carriers in the US to drive prices down. It strikes me every time to see how ATT charges 20x the price for 1/20th of the performance in data throughput & quality compared to many European carriers. To compare: in some European countries you would get 4GB wireless data with - speeds of 14.4 MBps on a pre-pay card (no monthly commitment) for a price of $6. Competition doesn't seem to really work here. Which is a more important problem, thatn the 1-digit % measurement error margin.
typical monthly data use is "overcounted by 5 to 7 percent"?! im scared to even think how much money AT&T has stolen from me over the years.
