I am seeing no evidence of Wi-Fi calls. You cannot test this using airplane mode. Wi-Fi calling uses your SIM to authenticate you to the T-Mobile network. In airplane mode the SIM is effectivity disabled, with Wi-Fi enabled and the cellular radio disabled, Wi-Fi calling will not work (at least this is my experience on all my other phones), On 6.0 I did notice in the LTE Discovery app during a call with Wi-Fi calling enabled, I was seeing something called IWLAN under network type appear during a call. I do not know what IWLAN is, but I have not seen this on any other phone that I own and it only appeared during a call with Wi-Fi calling enabled. This is no longer the case on 7.0.
There are 3 things that bug me about this whole Wi-Fi calling snafu.
I would assume by now that if we were ever going to get Wi-Fi calling we would have seen it. I think development on this phone is dead and we have all the features are ever going to get.

Wifi works on my Robin. No problems there.
Truthfully. I haven't had any problems with my Robin at all since the Nougat Install.

I take my earlier post back. We do appear to have Wi-Fi calling but there is some secret sauce involved.
I recall reading somewhere that under APN settings you need to have hipri listed under APN type. I am on Ting, a T-Mobile MVNO that supports WiFi calling.
In my APN for Ting, under APN type I have default,admin,mms,supl,hipri,internet,dun.
I was missing the last three from my list. When I remove hipri, WiFi calling stops working.
The only way I have been able to verify WiFi calling is with the LTE Discovery app. The app shows a connetion call IWLAN. That single strengh increases and decrease the closer/further I move from my WiFi access point.
I can also see in LTE Discovery see that when IWLAN is connected the celular radios go off. If I power cycle my router the celular singal returns until WiFi comes back up.
So yes, it appears we do have WiFi calling.

I am replying to bring raise the question again. Anyone have Wi-Fi calling working on Nougat+tmobile?
I do not with the default apn settings that came with the sim.
