Is ‘unlimited' phone data a ripoff?

Wall Street Journal personal technology columnist Joanna Stern talks with The Verge's Lauren Goode about why your cellphone's data bill is so confusing and how to get the most bang for your buck. Stern urges people not to switch carriers because one is seemingly offering a better "deal," noting that data plans always have strings attached. She says the buzzy new "unlimited" data plans being rolled out by the likes of Verizon and AT&T in response to rivals T-Mobile and Sprint are probably not worth the cost except for the most data-hungry consumers, and even then, they're not really "unlimited."
