How to Set Up a Conference Call on Any Phone (Including Flip Phones and Filtered Devices)

You've got three people who need to be on the same call at the same time. Maybe it's a work check-in, a family planning session, or coordinating volunteers for an event. Knowing how to set up a conference call sounds like it should be simple — and it is, once you know the steps. But if you're using a flip phone, a talk-only device, or a filtered phone without apps, you might be wondering whether conference calling is even possible.

Good news: it absolutely is. Most phones, including basic flip phones and filtered devices, support three-way calling right out of the box. You don't need a fancy app or a special subscription.

How Conference Calling Actually Works

A conference call is just a phone call with more than two people connected at once. There are two main ways this happens:

Three-way calling is the simplest version. You call one person, put them on hold, call a second person, then merge both calls together. Most carriers include three-way calling with standard phone plans at no extra cost. This works on virtually every phone, from a basic TCL Flip 2 ($124.99) to an advanced flip phone like the Wonder Phone ($399.99).

Conference bridge calling is what businesses typically use. A host sets up a bridge number (a virtual meeting room), and everyone dials in using that number plus an access code. The host enters a PIN to open the line, and participants join one by one. Some carrier plans support up to 8 lines on a single bridge.

For most people, three-way calling is the method you'll use. It's built into your phone service, it's free, and it takes about 30 seconds to set up.

How to Set Up a Conference Call on a Flip Phone

This is the question we hear most often. Can you do a conference call on a flip phone? Yes. The process is straightforward, and it works the same whether you're on a Pom Cellphone ($359.99), an Orbic Journey V, or any other basic device.

Step-by-Step: The Three-Way Calling Method

Step 1: Call Person #1. Dial them like you normally would. Wait for them to pick up and let them know you'll be adding someone else.

Step 2: Put Person #1 on hold. Press the "Flash" button, the "Send" key, or the soft key labeled "Add Call" (the exact button depends on your phone model). Person #1 won't hear anything — they're on hold.

Step 3: Call Person #2. Dial their number. When they answer, you can briefly chat before merging.

Step 4: Merge the calls. Press "Flash" again or tap the "Merge" soft key. All three of you are now connected.

That's it. Three participants, one call, no apps required. Three-way calling maxes out at three participants on a flip phone. For more people, you'll need a conference bridge (covered below).

What You'll Need

A phone plan that supports three-way calling (most do — call your carrier to confirm, it's almost always included free). Both phone numbers handy, either saved in contacts or written down. A quiet space — flip phones pick up background noise more than you'd think.

If you've never joined a conference call before (as opposed to hosting one), we have a separate walkthrough on joining a conference call from your cell phone that covers the participant side.

How to Set Up a Conference Call on a Filtered Device

If you're using a filtered phone like the Fig Flip II Pro (from $329.99), the Mind Phone, or the Tak S7, the process is essentially the same as the flip phone method above. These phones use standard phone dialers, so three-way calling works identically.

Call the first person. Once connected, look for a "+" icon or an "Add Call" button on screen (or use the physical keypad shortcut). Dial the second person. When they answer, tap "Merge" or press the merge key.

Filtered phones with touchscreens sometimes make this easier because the "Add Call" and "Merge" buttons are clearly visible on the call screen. The same three-participant limit applies.

Carrier-Based Conference Call Options

Need more than three people on the line? That's where carrier conference bridge services come in.

Many phone carriers offer a conference bridge number — a dedicated phone number that multiple callers dial into. The host gets a PIN to open the call, and each participant gets an access code.

Here's how it typically works: request conference calling from your carrier (some plans include it, others charge a small monthly fee). Get your bridge number and host PIN. Share the dial-in number and access code with everyone who needs to join. At the scheduled time, dial the bridge number and enter your host PIN. Participants do the same with the access code.

This method works with any phone — flip phone, filtered phone, even a landline. No special hardware needed.

There are also free conference call services available online where you can set up a bridge number without going through your carrier. You'd need internet access on a computer to create the account initially, but once it's set up, all the actual calling happens over regular phone lines.

If your work requires regular multi-person calls, our conference call guide for cell phones can help your team members connect smoothly from their end too.

Common Conference Call Issues and How to Fix Them

Echo or feedback. This happens when someone's speaker is too close to their microphone. Ask participants to mute themselves when they're not talking. On most flip phones, there's a mute button on the keypad.

Can't connect the third caller. Double-check that three-way calling is active on your plan. Make sure you're pressing the right button — on some phones it's "Flash," on others it's "Send" or a soft key labeled "Hold."

Hold music bleeding into the call. If someone accidentally puts the conference on hold instead of muting, their carrier's hold music plays for everyone. Always use mute, never hold.

Late joiners can't get in. With three-way calling, you can't add someone after the call is merged on most devices. If someone's late, you may need to hang up and restart. With a bridge number, latecomers can dial in anytime.

Poor audio quality. Usually a signal issue. If the call sounds choppy, try moving to a spot with better reception. Phones with HD Voice, like the E-Talk ($124.99) and the LG Exalt VN220, tend to sound clearer on conference calls because of better audio processing.

Tips for a Smooth Conference Call

Mute when you're not speaking. Background noise from two or three unmuted lines adds up fast.

Introduce everyone at the start. On a regular phone call, there's no screen showing who's on the line. A quick round of "Hi, this is [name]" keeps things clear.

Set ground rules if needed. For a longer call, mention upfront how you'll handle questions.

Dial in a minute early. Being on time avoids the awkward "can you hear me?" shuffle.

Announce yourself if you join late. "Hey, it's [name], I just joined" helps everyone stay oriented.

Keep your phone charged. A conference call can run longer than expected. The TCL Flip 2 gets up to 9 hours of talk time, but topping off beforehand is still a good habit.
