The simplest way to add people to a call on iPhone
You can add a second person to a call on iPhone while you're already talking to someone else. During an active call, tap the add call button (the plus sign with a circle around it), dial or search for the next person, and when they pick up, tap merge calls. This creates a conference call with all parties on the same line. The feature works on any iPhone model and doesn't require a special app — it's built into the Phone app.
The process takes about 30 seconds once you're comfortable with where the buttons are. You don't need to set anything up in advance or ask your carrier for permission. Most carriers include conference calling at no extra cost, though a small number of older plans or prepaid services may charge per minute for conference calls — check your carrier's terms if you're unsure.
Key Takeaways
- Tap the plus sign during an active call to add another person, then tap merge calls once they answer.
- You can add up to five people total on most iPhones, though some carriers limit it to three — test with your carrier if you need more than three people.
- If someone drops off the call, the remaining people stay connected; you don't have to start over.
- FaceTime audio calls can also host multiple people, and you can start a group FaceTime call directly without needing an active call first.
Step-by-step: merging calls into a conference
Start with an active call already in progress. Look at the bottom of your screen — you'll see several buttons arranged in a row. Find the button that looks like a plus sign inside a circle. Tap it.
The call screen will change and show you the keypad. You can now dial a phone number or search for a contact by name. Type the number or name, then tap the green call button. Wait for the person to answer.
Once they pick up, you'll see a button labeled merge calls at the bottom of the screen. Tap it. All three of you are now on the same call. If you want to add more people, repeat the process: tap the plus sign again, dial the next person, and merge once they answer.
How many people can join at once
Most iPhones allow up to five people on a single conference call, including yourself. However, some carriers — particularly older prepaid plans or regional carriers — cap conference calls at three people total. If you try to add a fifth person and the merge button doesn't appear, your carrier has likely set a lower limit.
The easiest way to find out your limit is to test it: add two people to a call and see if the merge button appears for a third. If it does, you can add more. If it doesn't, you've found your carrier's limit. You can also call your carrier's customer service line and ask directly — they can tell you in under a minute.
Using FaceTime audio for group calls instead
If you want to start a group call without an existing call in progress, FaceTime audio is often simpler. Open the FaceTime app, tap the plus sign to start a new call, then add multiple contacts by tapping the plus sign again for each person. Once you've added everyone, tap the audio button (the phone icon) to start an audio-only FaceTime call rather than video.
FaceTime audio calls support up to 32 people on newer iPhones (iPhone XS and later), which is far more than a standard phone conference. Everyone needs to have an Apple device or be able to receive a FaceTime link, but if your group is mostly iPhone users, this is often the fastest option. You can also start a FaceTime call and send the link to people via text or email, and they can join from any device with a web browser.
What happens if someone drops off the call
If one person hangs up during a conference call, the remaining people stay connected. You don't lose the entire call. The person who left will no longer hear anything, and you won't hear them, but everyone else continues talking normally.
If you're the one who needs to drop off but want the others to keep talking, just hang up — the call will continue without you. If you're managing the call and need to remove someone specifically, you can't do that from the iPhone interface. The only option is to end the entire call and start a new one with the people you want to keep.
Troubleshooting: merge calls button doesn't appear
If you tap the plus sign, dial someone, and they answer, but the merge calls button doesn't show up, the most common reason is that your carrier doesn't support conference calling on your plan. This is rare but happens on some prepaid plans or very old contracts. Call your carrier to confirm whether conference calling is included.
A second possibility is that the person you called didn't actually answer — they may have declined the call or it went to voicemail. Hang up and try again, making sure you hear them say hello before you look for the merge button. If you're on a weak signal, the merge button may also take a few seconds to appear after they answer. Wait a few seconds before assuming it's missing.
Conference calls on older iPhone models
The conference calling feature works on all iPhone models that run iOS 14 or later, which includes iPhone 6S and newer. If you have an older iPhone, you can still make conference calls, but the interface looks slightly different — the plus sign button may be in a different location or labeled differently. The process is the same: tap to add a call, dial the person, and merge.
If you're unsure whether your iPhone supports conference calling, the fastest way to find out is to try it. Start a call, look for the plus sign button, and tap it. If the button exists, your phone supports the feature. If you can't find it after looking at all the buttons on the call screen, your carrier or plan may not include conference calling.
Frequently Asked Questions
Can I record a conference call on my iPhone?
iOS doesn't have a built-in call recording feature for standard phone calls. You can record FaceTime audio calls by swiping down from the top of the screen during the call and tapping the record button, but this only works for FaceTime, not for regular phone conference calls. Some third-party apps claim to record calls, but they have significant limitations and may not work on all carriers.
Do all the people on the call need to be on iPhones?
No. You can add anyone with any phone — Android, flip phone, landline, doesn't matter. The conference call happens through your carrier's network, not through Apple's systems. The only exception is FaceTime audio calls, where everyone either needs an Apple device or needs to join through a web link you send them.
Will everyone see each other's phone numbers on a conference call?
No. On a standard phone conference call, people only hear each other's voices. They don't see phone numbers or caller IDs unless you tell them. On a FaceTime call, people can see the names or numbers of everyone in the call if they look at the participant list.
What if I need to talk to one person privately during a conference call?
Tap the person's name in the call screen and select "private call." This puts the conference on hold and lets you talk to just that person. When you're done, tap "merge calls" again to bring everyone back together. The other people will hear silence while you're on the private call.
Can I start a conference call on iPhone and continue it on a different device?
Not with a standard phone call — if you switch devices, the call ends. With FaceTime audio, you can start on iPhone and switch to iPad or Mac by answering the incoming FaceTime call on the other device, but you'll need to do this before the original call ends.
