Introduction

Conference calling is an essential feature for business meetings, family discussions, and remote communication. iPhone users often need to connect with multiple people at the same time, but many are unsure how to call conference on iPhone or how the merge calls feature works.

Apple makes conference calls simple, but the option is not always obvious, especially for new iPhone users. This guide explains how to make a conference call on iPhone step by step, what limits apply, and how to ensure clear and uninterrupted group calls.

What Is a Conference Call on iPhone?

A conference call on iPhone allows you to merge multiple phone calls into one single call, so all participants can talk to each other at the same time.

This feature works using:

• Your mobile carrier
• iPhone’s built-in Merge Calls option

No extra app is required for basic conference calling.

Requirements for Conference Calling on iPhone

Before starting, make sure:

• Your carrier supports conference calling
• You have an active cellular connection
• Participants are reachable by phone call

Some carriers may limit the number of participants.

How to Call Conference on iPhone

Using Merge Calls

1. Open the Phone app
2. Call the first person
3. Once connected, tap Add Call
4. Call the second person
5. When the second call connects, tap Merge Calls
6. Repeat steps to add more participants

All callers will now be connected in one conference call.

How Many People Can Join a Conference Call on iPhone?

Most carriers allow:

• Up to 5 participants (including you)

The exact limit depends on your carrier and region.

Real-World Example

Imagine a small business owner needing to talk with a supplier, a delivery partner, and a client at the same time. Instead of calling each person separately, they can create a conference call on iPhone and discuss everything in one conversation, saving time and avoiding miscommunication.

How to Add a New Person to an Existing Conference Call

1. Tap Add Call during the conference
2. Call the new participant
3. Tap Merge Calls

The new caller joins the group instantly.

How to Remove a Person from a Conference Call

1. Tap the Info (i) icon
2. Select the participant
3. Tap End next to their name

This removes only that participant, not the entire call.

Uses Across Apple Devices

Conference calls work across:

• iPhone
• iPad (with cellular calling)
• Apple Watch (via iPhone connection)

However, conference call creation is managed primarily from the iPhone.
