How to make a conference call from your iPhone
If your carrier supports it, you can set up a conference call on your iPhone with up to five people.
The number of participants on a conference call — as well as the ability to add, merge or disconnect individual callers — depends on your carrier. Contact your carrier for more information about your conference call options.
How to start a conference call
Dial the first person and wait for the call to connect.
Tap Add.
Select the second person and wait for the call to connect.
Tap Merge Calls.
The two calls merge into a conference call. To add additional people, repeat steps 2-4. If you don’t see the option to add another call, you may have reached the limit of participants for your carrier.
Only the person who started the conference call can see the names of all participants. But if a participant adds someone else, they can see the name of the person they added and the person who started the conference call.
If you don't see the merge call option, your carrier may not support it. Contact your carrier for more information about conference calling.
In addition to setting up a conference call on your iPhone, you can use Group FaceTime to talk to multiple people at the same time.
How to add an incoming caller
If you're on a conference call and someone calls you, here’s how to add them:
Tap Hold & Accept.
Wait for the call to connect, then tap Merge Calls.
If you don't see the option to merge calls, the current call or your carrier may not support it.
How to remove someone
While on a conference call, tap
.Tap End next to the person that you want to remove.
If you don't see the option to remove a caller, the current call or your carrier may not support it.
