NEW YORK ( TheStreet) -- Investors entered 2012 mapping out probabilities on how the telecom sector would consolidate, as also-ran carriers like Sprint (S), T-Mobile USA, MetroPCS (PCS) and Leap Wireless (LEAP) struggled to build networks to handle Apple (AAPL - Get Report) and Google (GOOG)-powered smartphones and compete against industry titans AT&T (T - Get Report) and Verizon (VZ - Get Report).

Along with the the plan the carrier announced an annual capital spending budget of $22 billion through 2015, with 60% allocated to the company's wireless network. The bet, in AT&T's case, appears to be that spending on network and service improvements is the way toward subscriber growth and long-term earnings.Competitors like Sprint and recently merged MetroPCS and T-Mobile appear to see a slightly different way forward to iPhone and Android-powered profits. Sprint continues to see unlimited iPhone data plans as its value proposition to consumers over competitiveness on wireless coverage and service, in the interim. From a pocketbook perspective, Sprint's unlimited data plans compare favorably to the tiered data plans of AT&T and Verizon; however, consumers need to take a leap of faith on coverage, data speeds and the company's improving financial picture. Sprint also is in the process of completing Network Vision, a rollout of a nationwide 4G network, but that spending plan pales in comparison to AT&T even after the company was effectively recapitalized in a merger with Softbank of Japan.
