For dropped calls, something for which AT&T has been consistently criticized, Sprint comes out worst. Metrico claims Verizon experienced a 2.1% call failure rate while AT&T had 2.8% and Sprint was worst at 3.7%.

Also take a look at the chart for the network speeds, AT&T really comes out ahead in this test. While I don’t doubt it has issues in Manhattan and San Francisco, it overall is a pretty decent network it would seem.
