Can Nexus 5X use Tmobile band 12 extended range lte AND Wifi calling?

[AC Question]

Hey all, just as the questions states. I would like a definitive answer on these two things as I find a little bit of conflicting info on the web. Im in a bad area for Tmobile and dont want to give up my data plan. My wifes Lumia 640 works fine and it has band 12 access and wifi calling which my old nexus 5 does not.

Thanks so much.
