Why do VoIP calls over WiFi still get counted as "minutes used" by mobile providers?
I assumed that Android calls made using google voice over WiFi connections would not count against voice minutes or data plan minutes because neither are being used. As is the case with all too many things, I have been proven wrong, and the google voice calls get charged against the minutes in our voice plan. I am a late adopter of smartphones (figured I was connected enough as it was, and I always carry my laptop with me, old dog, new tricks, etc.), so I must be missing something obvious about how VoIP over WiFi works. Please enlighten me!
