"My phone was ringing but I never heard it." "It's vibrating but making no sound — and I never put it on silent." "Only one person's calls never ring through." If any of those sound familiar, you're in the right place. This article focuses on incoming call ringtones — phone calls, FaceTime, and VoIP apps like LINE — not the Clock app alarm. If your alarm is the problem, that's a different issue with a different fix (→ How to Fix iPhone Alarms That Won't Ring | Focus Mode, Sleep Mode, and Volume Diagnosis). The root cause of a missing ringtone is usually one of several things: the Ring/Silent switch, the ringer volume slider, Focus mode settings, or where audio is being routed. This guide walks you through each possibility step by step, covering iOS 16, 17, and 18.

Ringtones vs. Alarms: What This Article Covers
How ringtone issues differ from alarm issues
Before diving in, it helps to understand that "iPhone not making sound" breaks down into two very different problems.
| Category | Sounds affected | Reference |
|---|---|---|
| Ringtone issues (this article) | Phone calls, FaceTime, LINE and other VoIP calls | This page |
| Alarm issues | Clock app alarms | How to Fix iPhone Alarms That Won't Ring | Focus Mode, Sleep Mode, and Volume Diagnosis |
By design, the Clock app alarm plays even when the Ring/Silent switch is set to silent and even when a Focus mode is active. Incoming call ringtones, on the other hand, obey the Ring/Silent switch and Focus mode settings — which is exactly why they can go quiet when you don't expect it. The causes and fixes are fundamentally different, so make sure you're reading the right article for your symptom.
Types of ringtones covered here
This article covers the following types of incoming audio:
- Phone calls: incoming calls to your cellular number
- FaceTime: FaceTime audio and video call alerts
- VoIP apps (LINE, WhatsApp, etc.): in-app call alerts
- Emergency alerts (some fixes differ for these)
If message notification sounds or social media notification sounds are the problem, the ringer volume setting may still be involved, but the primary place to check is Settings → Notifications and the per-app settings there.
Diagnose First: Match Your Symptom
"The ringtone isn't working" can mean very different things. Find the pattern that matches your situation and jump to that section first.
No sound and no vibration at all
The call came in — you can see the missed call — but there was no sound and no vibration. The most likely cause is that a Focus mode has "Silence All Calls" enabled, or Focus mode is blocking the call entirely. Also check the Silence Unknown Callers setting.
Vibration only — no sound
By far the most common symptom. The cause is almost always either the Ring/Silent switch is in silent position (showing orange) or the Ringtone and Alerts volume slider is at zero. Check the switch first.
Only one contact's calls don't ring
Calls from most people ring, but not from a specific person. The likely cause is that contact has a custom ringtone set to "None", or Focus mode is set to allow calls only from certain people and this person isn't on the list.
Doesn't ring when the screen is locked
Ringtone works fine when you're actively using the phone, but not when it's locked. Normally there's no intentional difference in behavior between those states. A Focus mode schedule that activates with the lock screen, or an audio output routing issue with Bluetooth, could be causing this.
Sound is going to AirPods instead
No sound from the iPhone speaker, but the ringtone plays through AirPods or a Bluetooth speaker. When an audio device is connected, it becomes the default output for ringtones too.
Quick-reference table by symptom
| Symptom | Likely cause | Check first |
|---|---|---|
| No sound, no vibration | Focus mode fully blocking calls / Silence Unknown Callers | Focus mode call permission · Silence Unknown Callers setting |
| Vibration only, no sound | Ring/Silent switch in silent / ringer volume at zero | Physical switch on left side of phone and Sounds settings |
| Specific contact never rings | Contact's custom ringtone set to "None" / Focus mode allow-list | Contact ringtone setting · Focus mode allowed people list |
| Sound coming from AirPods | Bluetooth audio routing | Switch output to "iPhone" in Control Center |
| Only LINE doesn't ring | In-app sound setting / iOS notification setting | LINE notification sound · Settings → Notifications → LINE |
| Problem started after iOS update | Software bug | Restart · Update to latest iOS version |
Check the Ring/Silent Switch (Most Common)
Orange line visible = silent mode
The single most common cause of a missing ringtone is the Ring/Silent switch accidentally being flipped to silent. It's the small toggle on the upper left side of the iPhone — easy to knock without noticing.
Here's how to check it:
- Hold your iPhone and look at the upper left side of the device.
- When the switch is pushed toward the screen (upward), the phone is in ring mode.
- When pushed toward the back (downward) and you see an orange or red strip in the slot, the phone is in silent mode.
- If it's in silent mode, flip the switch back toward the screen to restore ring mode.
When you switch to ring mode, a "Ringer" notification appears on screen showing the current volume level. If the volume looks low at that point, continue to the next section.
Note: even in silent mode, the Clock app alarm still rings — that's intentional Apple behavior. If your alarm is ringing while in silent mode, that's normal.
iPhone 15 / 16 Action Button models
The Ring/Silent switch was removed on iPhone 15 Pro, 15 Pro Max, iPhone 16, 16 Plus, 16 Pro, and 16 Pro Max, replaced by the Action Button.
By default the Action Button is assigned the same toggle behavior — press to switch between silent and ring mode — but you can reassign it to a different function in Settings. If someone changed the assignment, pressing the button will no longer control the ringer.
To check or change the Action Button assignment:
- Go to Settings → Action Button.
- Confirm that Silent Mode is selected.
- If something else is selected, tap Silent Mode to restore the ring/silent toggle.
To tell whether your Action Button model is currently in silent mode, open Control Center (swipe down from the upper right corner) and look for the bell icon next to the Focus mode button, or check the notification area.
Check Ringer Volume
Ringtone and Alerts slider
If the phone is in ring mode but the sound is very faint or inaudible, the Ringtone and Alerts volume slider may be turned all the way down.
To check and adjust it:
- Go to Settings → Sounds & Haptics.
- Find the Ringtone and Alerts slider.
- If it's near the far left, drag it to the right to increase the volume.
- Moving the slider plays a preview — confirm the volume sounds loud enough.
This single slider controls the volume for phone call ringtones, FaceTime alerts, and notification sounds together. No matter what else you configure, if this is at zero, you won't hear a thing.
The "Change with Buttons" setting
On the same Settings → Sounds & Haptics screen, you'll find a toggle called Change with Buttons. When this is on, the physical volume buttons on the side of the iPhone adjust the Ringtone and Alerts volume (not just media volume).
This can cause an easy-to-miss problem: the volume buttons get accidentally pressed in a pocket or bag, silently lowering the ringer volume to zero. If you want a consistent ringer volume, turn off "Change with Buttons" — the volume buttons will then only affect media playback and will no longer touch the ringer volume.
Focus Mode and Do Not Disturb Traps
iPhone's Focus modes — Do Not Disturb (DND), Work, Sleep, and others — can powerfully suppress incoming ringtones. Misconfigured settings here are a very common hidden culprit. For a deep dive into Focus mode settings and automation, see iPhone Do Not Disturb Guide | How It Fits Into Focus Mode and How to Automate It.
Checking "Allow Calls From"
When a Focus mode is active, you can restrict which callers can ring through. If the setting is "No One" or "Allowed People Only," calls from people not on the list will be silenced.
Steps to check:
- Go to Settings → Focus.
- Tap the mode that is currently active (Do Not Disturb, Work, Sleep, etc.).
- Tap Allowed Notifications → People.
- Under the "Calls From" section, check whether it's set to Everyone, Allowed People Only, Contacts Only, or No One.
- If you want calls to ring through, change this to Everyone or Contacts Only.
Also check whether any Focus mode has a schedule that turns it on automatically. A forgotten schedule can silently activate at specific times and suppress ringtones without you noticing.
"Silence All Calls" setting
Some Focus modes have a Silence All Calls option. When this is on, incoming calls produce no sound and no vibration at all — total silence, including any exceptions you may have configured.
To check:
- Go to Settings → Focus and open the active mode.
- Go to Allowed Notifications → Calls.
- Make sure Silence All Calls is not checked. If it is, uncheck it.
Focus mode detailed settings
There's also a Repeated Calls option in Focus modes. When enabled, if the same person calls twice within three minutes, the second call rings through regardless of your Focus settings. This is useful if you want to be reachable in genuine emergencies while staying undisturbed otherwise.
For the full guide to Focus mode configuration, see iPhone Do Not Disturb Guide.
Audio Routing (AirPods / Bluetooth / CarPlay)
AirPods connected: ringtone plays through AirPods
When AirPods or any Bluetooth headphones or speaker are connected to your iPhone, the ringtone output shifts to that device. Your iPhone speaker goes quiet, so if the AirPods are sitting on a desk or in a case, you won't hear a thing.
"I left my AirPods in my pocket and completely missed a call" is a classic version of this issue.
To switch audio output back to the iPhone speaker:
- Open Control Center (swipe down from the upper right corner).
- Tap the audio output icon (a triangle with circles) in the top-right corner of the Now Playing widget.
- Select iPhone.
Alternatively:
- Put the AirPods back in their case and close the lid (disconnects automatically).
- Go to Settings → Bluetooth, tap the i next to the device, and tap Disconnect.
CarPlay and car Bluetooth behavior
When CarPlay or a car's Bluetooth system is connected, iPhone audio routes to the car speakers. This is fine while you're in the car, but if you walk away with the phone while the Bluetooth connection is still active, ringtones will continue to play through the car speakers instead of your iPhone.
Use Control Center to switch the output to "iPhone," or temporarily turn off Bluetooth to fix this.
HomePod Handoff
If you have a HomePod at home and HomePod Handoff is enabled, incoming calls can ring through the HomePod when your iPhone is nearby.
You can change the Handoff setting from the HomePod settings in the Home app. If you prefer ringtones to always play on your iPhone rather than the HomePod, turn Handoff off.
Ringtone Settings
Settings → Sounds & Haptics → Ringtone
Verify that a ringtone is actually assigned and playing correctly:
- Go to Settings → Sounds & Haptics.
- Tap Ringtone.
- Confirm a ringtone has a checkmark next to it.
- Tap a different ringtone to preview it — confirm you can hear the preview play.
If the preview plays fine, the sound system is working. If even the preview is silent, go back and re-check the volume slider and Ring/Silent switch.
Per-contact custom ringtone set to "None"
If only a specific contact's calls are silent, check whether that contact has a custom ringtone set to "None."
Steps:
- Open the Contacts app and find the contact whose calls don't ring.
- Tap Edit in the upper right.
- Find the Ringtone field.
- If it says "None" or shows a custom value you don't recognize, change it to Default or pick a ringtone.
This setting can change unintentionally. Whenever only one person's calls aren't ringing, always check here first.
Custom ringtone has disappeared
Purchased or downloaded custom ringtones can vanish after an iCloud sync issue or after restoring from a backup. Here's how to get them back:
- Purchased via iTunes or Apple Music: go to Settings → Sounds & Haptics → Ringtone → Store and re-download.
- Created in GarageBand or a ringtone app: recreate and transfer to iPhone again.
- Synced from a Mac (Finder) or Windows (iTunes): reconnect the phone and sync again.
App-Specific Ringtones (LINE, WhatsApp, etc.)
In-app notification sound disabled
VoIP apps like LINE and WhatsApp control call alert sounds through their own in-app notification settings. If the in-app sound is turned off, you won't hear the call regardless of your iOS settings.
For LINE (steps may vary slightly by version):
- Open the LINE app.
- Go to Settings (gear icon) → Notifications.
- Make sure Notifications is toggled on.
- Make sure Ringtone is toggled on (for incoming VoIP calls).
For WhatsApp: go to Settings → Notifications → Ringtone and confirm a ringtone is selected (not "None").
Settings → Notifications → [App] → Sound
Even if the in-app settings are correct, the iOS-level notification settings can override them and mute the sound.
Steps:
- Go to Settings → Notifications.
- Tap the app whose calls aren't ringing (e.g., LINE).
- Make sure Allow Notifications is on.
- Make sure Sounds is on.
- If available, also check the Critical Alerts setting (some VoIP apps support this).
Keep in mind that when a Focus mode is active, even apps with Sounds enabled will be subject to the Focus mode's allowed-apps list. Check Settings → Focus → [Mode] → Allowed Notifications → Apps to make sure the app is included.
Silence Unknown Callers
What the setting does and who it affects
iOS has a feature called Silence Unknown Callers. When it's on, any call from a number not in your Contacts is silenced completely — no ringtone, no vibration, just a missed call notification in your call log.
It's a useful defense against spam calls, but the downside is that important calls from numbers you haven't saved — a new colleague, a delivery, a doctor's office — will also be silenced without any warning.
If this setting was turned on without your knowledge, it could be why certain calls never ring through.
How to turn it on or off
- Go to Settings → Phone.
- Find Silence Unknown Callers.
- If it's on and you want unsaved numbers to ring through, toggle it off.
If calls from people already in your Contacts are also not ringing, this setting is not the cause — keep working through the other sections.
iOS Updates and Known Bugs
Updating to the latest version
If your ringtone stopped working right after an iOS update, that version may have a software bug. Apple distributes patches for known issues, so updating to the latest version sometimes resolves the problem.
- Go to Settings → General → Software Update.
- If an update is available, tap Download and Install.
- After updating, test the ringtone.
Updates can take a while. Run them on Wi-Fi with sufficient battery — or plug in while updating.
Restart and force restart
iOS can occasionally get into a software "stuck" state where sounds stop working. A simple restart fixes this surprisingly often and is worth trying before digging into settings.
Normal restart:
- Face ID models (iPhone X and later): Hold the side button + either volume button → slide "Slide to Power Off" → wait a few seconds → hold the side button to power back on.
- Home button models (including iPhone SE 2nd/3rd gen): Hold the side button → slide "Slide to Power Off" → hold side button to restart.
- Or go to Settings → General → Shut Down, then power back on.
If the screen is frozen, try a force restart:
- iPhone 8 and later (including Face ID models): Quickly press and release Volume Up → quickly press and release Volume Down → press and hold the Side button until the Apple logo appears.
- iPhone 7 / 7 Plus: Hold both the Volume Down button and the Side button simultaneously.
Last Resort: Reset All Settings or Factory Reset
Reset All Settings
If nothing has worked yet, your iPhone's settings data may be corrupted. Reset All Settings restores Wi-Fi, Bluetooth, notifications, Focus modes, and sound settings to factory defaults — but it does not delete your photos, contacts, apps, or messages.
- Go to Settings → General → Transfer or Reset iPhone.
- Tap Reset.
- Tap Reset All Settings (do not tap "Erase All Content and Settings").
- Enter your passcode to confirm.
After the reset you'll need to reconnect to Wi-Fi and re-configure Face ID or Touch ID. Ringer volume and Focus mode settings will be back at defaults too, so set them up again as needed.
Back up and factory reset
If even Reset All Settings doesn't help, a full factory reset and restore is the final option. Make sure to back up first.
- Back up to iCloud: Settings → [Your Name] → iCloud → iCloud Backup → Back Up Now.
- Once the backup is confirmed, go to Settings → General → Transfer or Reset iPhone → Erase All Content and Settings.
- Follow the setup screens and choose to restore from your iCloud backup.
If the ringtone works after restoring, a specific app or setting was likely the culprit. If the problem persists even after a clean restore, speaker hardware failure is a real possibility — contact Apple Support or visit an Apple Store Genius Bar for a diagnostic.

Summary: Checklist in Order
Work through these steps in order to efficiently track down the cause:
- Check the Ring/Silent switch: Is the switch showing orange (silent)? On Action Button models, go to Settings → Action Button and confirm Silent Mode is selected.
- Check ringer volume: Go to Settings → Sounds & Haptics and make sure the Ringtone and Alerts slider isn't all the way to the left.
- Check Focus mode: Is a Focus mode active with "Allow Calls From" set to "No One" or "Silence All Calls" enabled?
- Check Bluetooth audio output: If AirPods or a car Bluetooth connection is active, is the ringtone playing there? Switch output to "iPhone" in Control Center.
- Check per-contact ringtone: If only one person's calls are silent, open that contact and verify the Ringtone field isn't set to "None."
- Check Silence Unknown Callers: Go to Settings → Phone. If it's on and the caller isn't in your Contacts, that's why it was silent.
- Check app notification settings: For LINE or other VoIP apps, verify both the in-app sound setting and Settings → Notifications → [App] → Sounds.
- Restart the iPhone: Clears temporary software glitches.
- Update iOS: If the problem started after an update, the fix may already be in a newer version.
- Reset All Settings: Last software-side option if settings data is corrupted (no data is deleted).
