@:-) Duh - ^ Why, of course - brain wasn't working last night - getting used to this newly flashed/upgraded 5s with iOS 8.4.0 - played all the hidden switches & settings. A little different compared to Android's Lollipops - now, got devices on both iOS and Androids.
So, I can report success, 5s on Airplane Mode (initially) only - WiFi enabled over Fios, able to make outgoing call - CID showing the assigned T-Mo # and incoming call on the T-Mo # ringing on the iPhone as well, sound quality & reception is good, clear audio.
It's a newly activated line using an unlocked Sony GSM fliphone & cut down to nano-size for the iPhone 5s. Another backup option abroad especially if I can use it for T-Mo WiFi calling on trips, without using cellular data or roaming charges (which aren't even allowed for prepaid's)

Had an AT&T chip in this VZW iPhone 5s initially, right after upgrading to iOS 8.4 - pop the T-Mo prepaid Sim & restarted, and got a prompt to download T-Mo settings and accepted it to install. Should've rejected it to see what happened or, at least for comparison of before & after ... anyway, it seemed fine & was ready to use and activated.
Supposed to be a PRL update ?? - under "Carrier" with iOS 8.4 came T-Mobile 20.0 settings, which, of course, not evening the boys @ HoFo forum have any idea what changes were made to the device.
Nexus 6 has support for WiFi calling on T-Mo but not officially on Nexus 5 ... but the geeks over at XDA's are working on "porting" over (waiting, as I have no immediate plans to trade-up for N6, mine is perfectly sized in near mint conditions, still plenty of life ahead)
