How to Receive Calls via Bluetooth on iPhone

This guide shows you how to pair your iPhone with Bluetooth headphones, speakers, or a car kit so you can answer and talk on calls hands-free. You’ll learn the pairing process, how to switch audio mid-call, and what to do when calls don’t route to your device.

What You’ll Need

• An iPhone running iOS 13 or later (the steps are similar on older versions).
• A Bluetooth audio device (headphones, earbuds, speaker, or car stereo) that supports hands-free calling (HFP profile).
• The device should be charged and in pairing/discovery mode (check its manual for the exact button combination).

Step-by-Step

1. Put your Bluetooth device in pairing mode. This usually means holding the power button or a dedicated Bluetooth button until the LED flashes (often red and blue). Consult the device’s manual if you’re unsure.
2. Open Settings on your iPhone. Tap the gear icon on your home screen.
3. Tap Bluetooth. Make sure the toggle at the top is green (on). Your iPhone will start scanning for nearby devices.
4. Wait for your device to appear under “Other Devices.” This can take a few seconds. If it doesn’t show up, turn Bluetooth off and on again, or put the device back into pairing mode.
5. Tap the device name to pair. You may see a popup with a pairing code or a request to allow contacts and favorites syncing—tap Pair or Allow as appropriate.
6. Wait for “Connected” to appear under the device name. It will also move to the top section under “My Devices.”
7. Make a test call to confirm audio routing. Call any number (like a friend or voicemail). When the call connects, you should hear it through the Bluetooth device.
8. If the call doesn’t auto-route, tap the Audio button on the call screen (it looks like a speaker icon) and select your Bluetooth device from the list.

Common Mistakes

• Not putting the device in pairing mode. Simply turning it on is not enough—most devices need a long press on the power button to enter discovery mode.
• Forgetting to enable Bluetooth on the iPhone. Check that the toggle in Settings > Bluetooth is actually on, not just in Control Center (which may only disconnect temporarily).
• Selecting the wrong device. If you have multiple Bluetooth devices, make sure the one you want is the one showing as “Connected” before the call.
• Assuming all Bluetooth devices support calls. Some audio devices are “media only” (A2DP) and don’t support the hands-free profile needed for calls. Check the specs if you’re unsure.
• Having the device paired but not connected. Pairing is one-time; connecting happens each time. If it says “Not Connected,” tap the device name to connect.

Tips

• Keep your iPhone and device close. Bluetooth range is about 30 feet (10 meters), but walls and interference can reduce that. Moving closer can fix intermittent audio dropouts.
• Use the call’s Audio button to switch between the iPhone speaker, the earpiece, and the Bluetooth device during a call. This is handy if you need to hand the phone to someone.
• Check the battery level of your Bluetooth device from the Today View (swipe right on the home screen) or the Batteries widget. Low battery can cause disconnects.
• For car kits, follow the car’s infotainment system. Some cars require you to initiate pairing from the car’s screen, not just the iPhone.
• If you use multiple devices, your iPhone will often auto-connect to the last one used. You can manually select a different one in Settings > Bluetooth.

Troubleshooting

Call audio still comes from the iPhone speaker.

• Tap the Audio button on the call screen and choose your Bluetooth device.
• Make sure the device is actually connected (check Settings > Bluetooth). If it says “Not Connected,” tap it.
• Turn the Bluetooth device off and on again, then reconnect.

The device pairs but won’t connect.

• Forget the device: In Settings > Bluetooth, tap the “i” next to the device, then Forget This Device. Put the device in pairing mode again and repeat the pairing process.
• Reset your iPhone’s network settings (Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings). This clears all Bluetooth pairings, so you’ll need to re-pair afterward.

Calls drop or audio is choppy.

• Move closer to the iPhone and away from other electronics or metal objects.
• Check for interference from Wi-Fi routers, microwaves, or other Bluetooth devices.
• Make sure the Bluetooth device is fully charged.

No sound from the Bluetooth device at all.

• Check the volume on both the iPhone and the Bluetooth device.
• Try playing music or a video to see if media audio works. If it does, the issue is specific to call audio, so re-pair the device.
• Restart your iPhone (press and hold the side button and either volume button, then slide to power off).

Frequently Asked Questions

Why does my iPhone keep disconnecting from my Bluetooth device?
This is often due to low battery, interference, or the device being out of range. Try charging the device, moving closer, and forgetting/re-pairing if the issue persists.

Can I receive calls on multiple Bluetooth devices at once?
No, the iPhone supports one active audio device for calls at a time. You can switch between them during a call using the Audio button.

Will my Bluetooth headphones work with Siri and voice prompts?
Yes, if the headset supports the hands-free profile, Siri and call prompts will route through it. You may need to press the headset’s call button to activate Siri.

Do Bluetooth speakers work for phone calls?
Only if they have a built-in microphone and support the hands-free profile (HFP). Many portable speakers do, but some are media-only. Check the specs.

Why does my car show as paired but not connected?
This can happen if the car’s system is already connected to another phone, or if the car requires you to select the phone from its menu. Try disconnecting other phones and manually connecting from the car’s screen.

How do I stop calls from going to my Bluetooth device?
You can either turn off Bluetooth on the iPhone (which will disconnect the device) or, during a call, tap the Audio button and choose “iPhone” to route audio back to the phone’s speaker.
