Difference between outgoing calls and cancelled call iPhone

Outgoing calls connect successfully to the recipient, while canceled calls are those that are initiated but never connect.

A canceled call doesn’t charge you any minutes or data, unlike an outgoing call. 

You can see canceled calls in your call log if the recipient doesn’t pick up or the call is cut off prematurely.

 Canceled calls happen when the recipient declines the call manually, and they may show up as missed on their side.

 Wi-Fi Calling can reduce the number of canceled calls by routing them over Wi-Fi instead of cellular networks.
