The 6T is the follow-up to the OnePlus 6 launched earlier this year, which got high marks from CNET for delivering the look, feel and performance of a high-end flagship phone at a significantly lower price. In an exclusive interview with CNET, OnePlus CEO Pete Lau said the 6T won't have a headphone jack, but will have an in-screen fingerprint sensor. 

T-Mobile is expected to be the exclusive US carrier partner for the OnePlus 6T and it will be optimized for T-Mobile's new 600 megahertz spectrum band network, according to several people familiar with the launch plans. OnePlus will still sell its standard global version that's unlocked and able to run on either AT&T or T-Mobile, as well as networks overseas.
