One of the iPhone’s features is the option to place a three-way call – also known as a conference call – which lets you talk to two people from different phone numbers simultaneously. If you need to talk to multiple friends at once to plan a party or multiple employees at your workplace, a three-way call allows everyone to hear and speak to each other on the same call. Making a three-way call on the iPhone is similar to making a regular call. All iPhone 4S models can make a conference call, but only the GSM iPhone 5 models can participate in conference calls. Check with your cellular provider to verify that your plan allows for conference calling. Tips Writer Bio
