The Apple Watch Series 10 does not support answering calls from multiple contacts simultaneously in the traditional sense. You can only handle one active phone call at a time. However, it does allow for Group FaceTime audio calls, which enables you to start a call with one person and then invite additional contacts to join during the call.
Here's how it works:
- Single Phone Calls: You can answer one incoming call at a time. If another call comes in while you're on a call, you will have the option to hold the current call and answer the new one, but you cannot talk to both callers at the same time.
- Group FaceTime Audio Calls: You can initiate a FaceTime audio call and add more participants. This feature allows for multiple callers to join the same conversation, but it requires that the initial call is a FaceTime audio call rather than a standard phone call.
To summarize:
- Traditional Phone Calls: Only one active call at a time.
- Group FaceTime Calls: Multiple contacts can join after initiating the first call.
