T-Mobile’s eighth Uncarrier event is going live tomorrow morning

T-Mobile is closing out the year with another Uncarrier event. T-Mobile, the nation’s fourth largest wireless carrier, will hold an “Uncarrier 8.0” event at 7:30 a.m. PT on Tuesday, hosted by CEO John Legere. T-Mobile provided little information about the event, but said it plans to “share how we continue to rewrite the rules of wireless.” T-Mobile’s last Uncarrier event, held a day after Apple’s iPhone 6 and iPhone 6 Plus were announce in September, broadened the carrier’s Wi-Fi calling and text message features. T-Mobile has shaken up the wireless industry with its Uncarrier events and programs, including eliminating contracts, ditching international roaming rates and offering data-free music. Part of a cut-throat effort to win new customers and retain existing ones, T-Mobile has been the beneficiary of aggressive moves over the past year and a half. Its Uncarrier campaign and Legere’s brash attitude have succeeded in driving its turnaround and helped add 2.3 million new customers in the last quarter.
