More and more, the voice calling feature is becoming obsolete. With the exception of hands free use in the car while driving, I essentially never use my phone to make calls.

Text is asynchronous and thus the other party can respond when it's convenient. I resent voice calls as an intrusion and rarely answer them.

The next killer app for me is in the network and it's the SHAKEN/STIR validation helping to show some UI indicator of a "verified caller ID". Luckily it looks like mobile carriers will be there first and when they are it's game over for spam.
