How Much Will T-Mobile's Contract-free Plan Save You?
Now that all four of the major carriers offer the iPhone 5 we decided to take a look and see how much you would actually save by going with T-Mobile over Verizon, AT&T, and Sprint.
For the comparison Zagg (the people who made the first chart) used 4GB of data and unlimited talk and text. Note that Sprint only offers unlimited everything so there will be 2 blank spots in the chart for voice/text and data. All charts will be over a period of 2 years.
It looks like all other carriers will cost you the same, but you will save $580 over 2 years if you go with T-Mobile for a single user.
The Verge did the same thing, but also made one for a family of 2 and 4. While the story is true for the one person, Verizon is a better choice for a family of 2 and 4.
