Hmmmm I'm really interested in that article saying that Tmobile announced that wifi calling would work on the two nexus by launch. I have never heard of a non-tmobile phone supporting wifi calling (the nexus 5 definitely wouldn't).
While this is pretty cool, I had major major issues with wifi calling on my Htc One m8. Signal would randomly switch from wifi to cellular and back again, dropping everything I was doing (including calls) and making the phone unusable for a few seconds. Most annoyingly, I could not send MMS over wifi and had to either turn wifi off or disable wifi calling every time I wanted to send a picture via text. And, any texting service (like mightytext) that allows me to text from my desktop or tablet wouldn't register any texts as "sent", even though often they did (but I could never tell for sure until the person responded). For the past few months I've left wifi calling off and my life has been so much better. Voice quality has also been way better since turning off wifi calling.
So, my question is...will any of this be improved on these new phones since they are much improved hardware? Anyone have other tmobile wifi calling experience to make me want to use it again? Will mms finally work??
