I make zero calls, people know to reach me by whatsapp, except say Citibank which sends a fraud check by SMS which I cant respond to and my credit card gets shutdown. I don't want a stupid Google voice like app, and it all goes to hell when porting a number. WhatsApp is so reliable. iMessage goes to hell unless you put +XX country codes for all of your contacts.
