Moto X Style So, how do we get T-Mobile to carry it?

Have you thought about calling T-Mo to cancel and telling them it's because of your home service? Usually they'll send you a signal booster for free. Iirc they have 2 diff kinds and you'll want the non Asus WiFi router version which I believe only works through WiFi calling.

The signal booster and/or router is free. You don't have to threaten to cancel service. Just walk into a store and ask for one. Seriously. It's a provided option no charge and employees know it's no cost.

This is true -- I only paid $7 for shipping on my booster (nothing else). :).
