Update – Turns out it was a bit premature. T-Mobile has confirmed that they are still working on it.
When the Nexus 6P was launched a couple of months ago, it was noted that T-Mobile’s Band 12 LTE was not supported by the phone (or the Nexus 5X for that matter). The good news is that Google promised that they were working on it and it looks like Nexus 6P owners will have to wait no more.
T-Mobile has recently added the Nexus 6P to the list of devices that are compatible with Band 12 LTE. However we expect that we will still need to wait for Google to push out an update that will enable the functionality, but given that the phone has already been listed as supporting Band 12, it probably won’t be too long before the update arrives.
As Android Police speculates, it might arrive with Google’s December security update, but we’ll just have to wait and see. That being said, for those wondering what the big deal is, basically T-Mobile’s Band 12 has been disabled on most phones until they have obtained the proper certification from the carrier.
This means that in certain areas where T-Mobile only has Band 12 active, you will have LTE coverage but you will not be able to make phone calls unless you have VoLTE. The Nexus 5X has yet to be certified for Band 12 but now that the Nexus 6P has, hopefully it won’t be too long until the Nexus 5X is given the same treatment.
