Digital Trends – Well this is interesting: New research by Validas, a company that analyzes wireless phone bills, found that there is barely any difference in the data usage habits of the top 5 percent of tiered and unlimited wireless users. This comes after three of the four major US wireless carriers have begun to throttle speeds for those so-called âdata hogsâ on unlimited plans. What the findings potentially uncover is that the new policies are ostensibly less about the initial justifications for the limits â esoteric concerns over network bandwidth and wireless spectrum shortage, of which AT&T specifically referred to as an impetus for their policy shift â and more about moving legacy unlimited data plan holders to more modern, tiered contracts.
