A conference call lets three or more people talk together in the same phone call. On iPhone, you can add a second person while already in a call — no special app needed. The feature is built into the standard Phone app and works with any phone number.
The process is called "merging" calls. You call person one, then use the "Add Call" button to call person two while putting person one on hold, then "Merge" both calls together. All three of you can then talk at once.
Your ability to make conference calls depends on your carrier. Most US carriers (Verizon, AT&T, T-Mobile) support up to 5 people in a single conference call. Some prepaid or international plans may not support this feature — if the "Merge Calls" button appears grayed out, contact your carrier.
Wi-Fi Calling, if enabled, also works for conference calls as long as everyone is connected to cellular or Wi-Fi.
Note that conference calls using the Phone app are not encrypted like FaceTime calls — they use the standard phone network. For private conversations, use FaceTime Group Calls or Zoom instead.
