>A 3-GB data plan from T-Mobile for your iPad mini is $30 per month. Yet if instead of an iPad mini it’s an iPhone 6 Plus, which requires a voice plan too, your phone bill is $60 per month.<p>This is just not true. T-Mobile has a phone plan that's 5GB of fast data, unlimited slow data, a handful of minutes you can ignore.<p>I have a cheap plan that has unlimited minutes and unlimited slow data, which I think hints at the real end-game. Don't toss out the old infrastructure, just stop price gouging it now that data can truly compete.
