At long last, Android 5.1 is rolling out officially for T-Mobile customers rocking the Nexus 6. The most concrete confirmation comes from T-Mo’s software updates page which now shows the N6 for the first time, and states that the Android 5.1 update process is completed.

To add to that, the company’s product guru, Des tweeted out to confirm that the software is making its way to Nexus 6 now:

For all you guys & gals out there waiting for 5.1 with VoLTE on your @TMobile #Nexus6 – the rollout has started! Thanks for your patience!

If you have a Nexus 6, and it hasn’t shown up yet, give it some time. The update comes with VoLTE and HD Voice call support as well as unlocking the device’s potential to pick up the carrier’s 700MHz frequency airwaves. The update weighs in at around 409MB and can be downloaded over-the-air on a Wi-Fi connection. The software versions page indicates that you won’t be able to download and install it over cellular network yet, but that ability could come soon.

As we mentioned in a previous post, Wi-Fi calling does not come in this update. That will come separately, once all parties involved are in agreement that it works consistently well.
