How to make a 3-way call
Add a third person to a live call on iPhone or Android in a few taps — plus how to run a larger conference call for business.
How to make a 3-way call on iPhone
- Call the first person as usual.
- Once connected, tap add call — the first person is put on hold.
- Dial the second person and wait for them to answer.
- Tap merge calls to join everyone on one line.
To add more people, repeat *add call* then *merge* (most carriers allow up to about five). Tap the i / Manage button to see participants or drop one.
How to make a 3-way call on Android
- Call the first person.
- Tap Add call and dial the second number.
- When they answer, tap Merge (or *Merge calls*) to join the two calls.
The exact wording varies by phone — on Samsung it's Merge. Three-way calling has to be supported by your carrier; if the merge option is greyed out, that's usually why.
How many people can you add?
Cellular conference calling typically caps around five or six participants, and the exact limit is set by your carrier, not your phone. That's plenty for looping in a colleague or a spouse on a call.
Once you need more than a handful — or the call is scheduled ahead of time — a phone-based merge gets clumsy, and a dedicated conference service is the better tool.
For bigger or scheduled calls: use a conference service
For larger or planned calls, skip the phone merge and use a dial-in conference service or a video app (Zoom, Google Meet, Microsoft Teams). Everyone joins the same bridge or link, there's no per-person merging, and you're not limited by your carrier's participant cap.
Business VoIP providers usually include a conference-call number with the plan, so a scheduled call is just a shared dial-in.
The calls that cost you are the ones nobody joins
A 3-way call is a handy way to loop someone in — but for most small businesses the expensive calls are the inbound ones that go unanswered while you're busy on another line.
RingOwl is the safety net for those: a 24/7 AI answering service that picks up every call you can't, answers questions, books appointments into your calendar, and texts you a summary — so no customer hits a busy signal or voicemail.
