Verizon needs to stop dragging their feet with the release of the software patch that will give us VOLTE.
the reality is software from the Google Play Store can ready effectively emulate AC 1.0.
You can get any number of VOIP phone dialers, but my favorites are Vonage, Skype, Google Voice & Viber.
For Video Calling, I currently use IMO between my Note 4 & my wife's iPhone 6. It's the closest thing I've seen to Apples Facetime.
Do Verizon, what gives?
Why are you giving the GNote 4, the love that it deserves.
