Anyone who has ever suspected that carriers overcharge for monthly wireless data can now feel some vindication: A new study from UCLA suggests they’re probably right. MIT’s Technology Review says that the study looked at mobile data calculations from two major wireless carriers and found that while carriers usually got things right, they “tended to overcount” when they did err in their estimates. And this doesn’t just affect people who spend their entire days streaming video either, as the researchers found that “even typical use of a phone could lead the data to be overcounted by 5 to 7 percent.” Read the full story at Boy Genius Report.
