Ranking the top 9 U.S. wireless carriers in Q4

As the quarterly earnings season comes to a close, it's time to look at the numbers--and the numbers for T-Mobile US (NYSE:TMUS) were extremely good. The carrier in the fourth quarter added far more new customers than Sprint (NYSE:S) and AT&T Mobility (NYSE:T), and almost as many as market leader Verizon Wireless (NYSE:VZ).

Specifically, T-Mobile added 1.6 million new subscribers in the fourth quarter, just shy of the 1.9 million added by Verizon. According to figures provided to FierceWireless by Strategy Analytics, that's far above the 809,000 new customers AT&T netted and the 482,000 that Sprint collected.

T-Mobile has also enjoyed improvements to its churn, though its average revenue per user has stayed largely the same.

T-Mobile's results were such that a number of financial analysts raised their expectations for the "uncarrier" in 2014: Credit Suisse said it raised its 2014 net add predictions from 1.525 million customers to 2.450 million customers.
