T-mobile have these in home hot spots for WIFI calling.

It's really nothing more than a T-mobile tweaked Asus AC dual band router.

I have not dug to much into it but it's a version of the Asus I've recommended here several times.

Retail it's minimum $150 up to $300 depending on which Asus it's based.

They used to give it to you for a $25 deposit but are currently waiving that.

So if you are a T-mobile customer they are basically lending you a -$200 router for as long as you like.

You can't beat that.
