The CTIA just recently released some stats on the domestic wireless industry. Incredibly, mobile data usage posted a 104% jump to 1.16 trillion megabytes of data delivered through U.S. mobile data networks between July 2011 and June 2012. That's been driven both by the migration to faster 4G LTE and broader adoption of mobile devices such as smartphones and tablets. Since Sprint Nextel (NYSE:S)still offers unlimited data plans for a fixed fee, it has no direct revenue to gain from increased data usage, while its larger rivals AT&T (NYSE:T) and Verizon(NYSE:VZ) have since switched to tiered plans, where more usage translates into more revenue.
