T-Mobile introduced a whirlwind of changes last year as it rebranded itself as the "Un-carrier," with perhaps its most substantial shift being the decision to forgo annual contracts, breaking away from a long-standing practice among carriers in the US. Now the company is doing away with another perpetual mobile pain in the rear by eradicating its domestic overage charges. This applies regardless of whether you're on a Simple Choice plan, the new Simple Starter, or an older plan - and it will take place starting in May, with those bills arriving in June.

CEO John Legere, not one to shy away from making grand gestures, has taken to Change.org with a petition calling on AT&T, Sprint, and Verizon to abolish their overage charges as well.

This announcement follows two days of preceding ones last week, starting with the unveiling of a new $40 "Simple Starter" plan with unlimited talk/text and 500MB of data. T-Mobile came back the next day with Operation Tablet Freedom, offering LTE tablets for the price of their Wi-Fi variants. The company then paused on Friday for the global launch of the Galaxy S5 and its personal launch of its HTC One M8.
