Although the Google Nexus 6 is a fairly universal phone that works on all major U.S. carriers, those who use it on T-Mobile will get some custom features, including support for Wi-Fi calling, says TMoNews.
T-Mobile is working to add the feature and hopes to release it this quarter according to a tweet from one of the carrier’s senior product spokesman:
@bkerensa @DrMacinyasha It's under development now and we're hoping to have it out in Q1 – it'll be close!

The twitter conversation started with a reference to [company]T-Mobile[/company]’s rollout of [company]Google[/company] Android 5.0 for the Samsung Galaxy S5, but turned to new features for the Nexus 6. The company has already announced the Nexus 6 will gain support for the carriers 700MHz LTE bands through a software update, which is expected early this year.
The T-Mobile representative noted on Twitter that not all of the new features may appear in a single update; the carrier will likely add 700MHz support, VoLTE calling and Wi-Fi calling in stages but I wouldn’t be surprised if all of those are readily available in the first half of 2015.
