Hello, a few months back I found a question answered here in regards to wifi calls showing up on the bill. The answered marked as CORRECT was an answer by a verizon tech who said that if your phone is not connected to the network - meaning it's on airplane mode and the call is going directly over wifi (no 3g of 4g service due to being in airplane mode) it will not show up on the bill nor will it count towards minutes.
However, I just looked on my bill and all the calls I have made over wifi when I know for a fact my phone was on airplane mode and just connected to my home wifi and there was NO verizon service at all, are listed on my bill and the minutes are logged.
How is this possible if I am going strictly over wifi and in airplane mode?
