T-Mobile will hold its next “un-carrier” event on June 25.

T-Mobile has started teasing its next big announcement online, which is set to take place on Thursday.

In an invitation to the press, the Bellevue-based carrier, said two years ago, it promised to take on the worst of the “carrier abuses,” and it’s been “pounding out a drumbeat of industry-rocking Un-carrier moves ever since.”

Some of the “un-carrier” initiatives to date have included killing off roaming fees, offering to pay customers’ early-termination fees, launching an unlimited music streaming and announcing it would give away iPhones for week-long test drives to tempt customers into switching networks.

But rather than releasing an all-new feature this week, this time it will be revamping some of its ongoing initiatives over the course of the next few weeks, with Thursday designated as the big kick-off. Is that a sign that some of its competitors are starting to match its offers and they are as appealing as they once were?

“Over the coming weeks, we’ll be amping up several of our most wildly popular Un-carrier moves in a major way – making them even bigger, even better, even ballsier,” the invitation says.

In a video advertising the event, T-Mobile recaps the eight moves made to date, with the company’s loud-mouth CEO John Legere narrating along the way. He ends the clip, promising that “We will not stop.”
