T-Mobile

I've seen some posts that Marshmallow bakes in WiFi calling. Try the Nexus 5 forum.

Kinda strange since I've always thought of Tmobile as the Nexus phones unofficial partner in the U.S.

VoLTE is enabled over non-band 12 LTE as well. Just want to point that out since it isn't band 12 only for VoLTE.

While true, the "trick" about VoLTE for Band 12 is that, in several areas, there is only Band 12 coverage -- since Band 12 is lower frequency, it works over a longer distance and also has better building penetration. For this reason, VoLTE is a bigger deal on Band 12 as, without VoLTE, you could easily have your phone showing it is connected but unable to make a phone call -- since it is out of range of Band 2 and 4 (the other T-Mobile bands) so can't drop down to 2G or 3G connections.

Agreed -- I was just pointing out that VoLTE isn't only band 12.
