T-Mobile is ready to reveal the details of the "new" T-Mobile on March 26.
T-Mobile is changing radically and on March 26 the carrier will reveal the details. The media invite for the event reads: "We're still a wireless company. We're just not going to act like one anymore."
What's behind that tag line are the new simplified rate plans without contract. See this leaked brochure on TmoNews for a glimpse on what UNcarrier is.
T-Mobile is also expected to tout its LTE plans and maybe is also revealing its Apple device plans.
