I just got an update on my G4 that enables Wi-Fi calling. I'm waiting for my V10 to get back from LG, so I was curious if anyone has gotten it on the V10 yet?
I have the Verizon version and regularly make use of the wifi calling feature since Verizon cellular coverage is so weak in my house. 3G 2/5 bars is typical, 1x rears its ugly head about half the time. The change over happens automatically, but its not completely seamless. There's a ~1 second delay and a screen icon when the phone switches over to wifi calling.
Wi-Fi calling came with my T-Mobile V10. I used it a few times and turned it off since I have unlimited calls and text.It worked very well the times I used it.
