The way they work is they take the cellular signal from the phone and convert it into a digital voice over IP signal basically which would be data, and then send the data over the clients Ethernet or home internet carrier. So what they are essentially is a cellular to data bridge. They do not need a cellular signal from a local tower to operate since they do all of their communications from the phone and to the phone via its own cellular connection, and all communications from it to the Verizon network and other phones via the Internet. Wifi calling will eliminate the need for these devices so the point was well taken that with wifi calling these devices would no longer be necessary.
Not sure how well it'll work on Verizon but on T-Mobile all I needed was a half decent Wi-Fi signal that was at least 2Mb fast and it was as clean as their network calls. Basically inside of any building that had a Wi-Fi signal that I could connect to I never had to worry whether I had gsm or not. It's basically switches network calls to voip calls.
I get how WiFi calling works. I was talking about vzw's network extenders. Ha
When they suggested I go that route and said they were sending me one for free it never showed up. I called and asked where it was, they said they'd decided not to follow through because it wasn't going to help. This was during the time they shut cells down in my area and said they weren't going to add anything back, which ended up with me leaving them.
