How to Make a Conference Call in an iPhone

Making a conference call in an iPhone is pretty simple. But, my friend wasn’t able to make a conference call on his iPhone as he wasn’t aware of how it’s done. Well, if you are wondering how it’s done, then have a look below:
Firstly, call any contact that you would like to start a conference call with.
Next, click on ‘Add Call’ and call another contact. When you do this, the first call is put on hold.
Now simply click on ‘Merge Calls’ to create a conference between the two contacts and you.
You can also add more contacts in the conference by repeating the above steps.
You can also merge an incoming call. To do so, all you need to do is press the ‘Hold Call’ and ‘Answer’ buttons, then simply click on ‘Merge Calls’.
