After 14 iterations, T-Mobile can no longer call its “Un-carrier” events unusual. And after upending so many aspects of wireless service in past such announcements, the odds of a groundbreaking shift in its offerings get increasingly unlikely.

The company has kept its descriptions as vague as ever, from CEO John Legere’s “one more thing” aside in its Aug. 1 earnings call (“Isn't it about time we shake things up in this industry again?” he said) to a video he tweeted Aug. 8 (showing him wheeling a wooden box labeled “Decommissioned” into a warehouse filled with boxes bearing such labels as “Contracts” and “Data Limits”).
