ATT just announced its financial results for Q4 2013 — revenue and subscribers have continued to grow, although not at the rapid pace that Verizon announced last week. ATTs total wireless revenue hit $18.4 billion for the quarter, up 4.5 percent year over year. Data revenues grew at an even higher rate — its $5.7 billion in data revenue was up 16.8 percent year over year, and ATT was proud to note that it posted its lowest-ever post-paid churn rate of 1.11 percent. In terms of new customers, however, ATT couldnt keep up with Verizon despite that low churn rate.
