When do I start getting charged for a phone call?

Whenever you call someone who is charging for this specific voice call, you will start to get charged for the entire first minute 20 seconds after you initiated the call. If a call hungs up before 20 seconds, it doesn't get charged because we assume the quality of the conversation forced people to disconnect. After 20 seconds have passed, the full minute gets charged if the call ends before 60 seconds.
