I tried the beta app in my Moto G 4G (first gen) running CynaogenMod 13 Nightly (android 6.0.1) and it setup/registered fine, it then asked me to reboot my phone and after that it could connect to 800 (cell ID 8) when forced to LTE only. However the intouch app force closes when trying to open it but the notification does show '4G calling ready'. I couldn't test calling since I can't open the app.
I've since
uninstalled the app on my Moto G and it seems the 800 data connection remains and works (7.2down, 1.7up), but definitely no means of testing calling now.

Even more interesting, having put my Three SIM back into my Nexus 6 I
seem to still be able to connect to 800 on that now too, I think... the eNBI and TAC numbers (7565/5057) are the same on there as they were for cell ID 8 on my Moto G - can anyone with more technical knowledge confirm or not that as these are the same values that the same frequency/cell ID would be used?
I do get similar download/upload speeds as on my Moto G.
Gnet track doesn't seem to show the connection for some reason (shows dashes rather than the actual value) however Network Signal Info on my Nexus 6 does show the values:

Edit: toggling to non-LTE only and back again seems to help gnet track register better and does show cell ID 8
