Last year was a huge one in the U.S. telecom space for a number of reasons. In more ways than one, 2013 could go down as the year of the comeback as several key names bounced back and more.

However, perhaps no storyline has had a greater impact on this key domestic market than the resurgence of the recently revived T-Mobile (NASDAQ:TMUS). In the wake of its failed deal with telecom giant AT&T (NYSE:T), the then-struggling T-Mobile was given roughly $4 billion in cash and spectrum for the deal failing to go through.

AT&T might never forgive itself.

T-Mobile shakes things up
In part, the funds for the failed AT&T merger have helped T-Mobile claw its way back into the competition. In fact, with some of its recent plan pricing and promotions, T-Mobile has ironically become one of the primary agitators for AT&T.

Recently, T-Mobile and Verizon (NYSE:VZ) reached a deal in which T-Mobile will purchase additional low-frequency spectrum from Verizon. The deal will result in roughly $2.4 billion in proceeds for Verizon. Not bad for a day's work.
