iPhone sound settings: tones, vibration, quiet alerts and snooze

Sound is spread across several apps on an iPhone, which makes simple changes hard to find. This guide covers the five settings people look for most: notification tones, vibration patterns, quiet notifications, how long the phone rings before voicemail and how long an alarm snoozes. Menu names can differ a little between iOS versions, so use the search field at the top of Settings if something is missing.

How to change the notification sound on iPhone

The same menu has Ringtone, Voicemail, Sent Mail and other alert sounds. If you only want one person to sound different, open Contacts and pick them, tap Edit, then Text Tone or Ringtone, choose a sound and tap Done. That is useful for a partner, a parent or a work number you never want to miss.

Third-party apps decide their own sounds. WhatsApp lets you pick one in WhatsApp › Settings › Notifications, but many apps, including Instagram and Snapchat, do not offer a choice at all. If you want a custom sound, buy one in the Tone Store, or make one in GarageBand and export it as a ringtone. It then appears in the tone list. If your phone is silent for calls, read this fix for an iPhone that does not ring.

How to change vibration on iPhone

Under Sounds & Haptics you can also choose when the phone vibrates: always, only in silent mode, or never. For one contact, set a pattern in their contact card in the same way as a tone. Stronger vibration is not a setting. A pattern such as Alert or Heartbeat feels stronger than a short tap, and a custom pattern made of long taps feels stronger still.

To turn off all vibration, open Settings › Accessibility › Touch › Vibration. Be careful: this also turns off vibration for emergency alerts. If your iPhone does not vibrate even though you want it to, check the same switch, then confirm Haptics is not set to Never, and make sure Silent mode is not hiding the vibration you expect.

Deliver Quietly and alerts that make no sound

Deliver Quietly sends an app's notifications to Notification Center without a sound, banner or badge. It is handy for noisy apps, and a problem when you want to hear an app and cannot work out why you do not. On newer iOS versions the Deliver Quietly button was removed. The same result now comes from turning off sounds and banners for an app.

If only one chat is silent, Hide Alerts is on for that chat. In Messages, swipe left on the conversation and tap the bell to bring alerts back. On older iOS, you can also swipe left on a quiet notification, tap Options or Manage and choose Deliver Prominently. For a specific messaging app that stays quiet, such as WhatsApp alerts that never arrive, check its own settings and battery rules as well.

How to change the number of rings before voicemail

There is no iPhone setting for this. Your carrier controls how long the phone rings, and the iPhone only follows. On AT&T, T-Mobile and many other carriers that use the GSM system, you can change it with a code. On Verizon, the codes do not work, and you need to contact customer service.

If you get an error, your carrier may not support the code, or the voicemail number is wrong. Call the carrier and ask them to change the no answer time for you. Longer than 30 seconds is usually not allowed. If callers never reach voicemail at all, or you cannot set it up, read about setting up voicemail on iPhone and changing your voicemail greeting. Missing calls entirely is a different problem, covered in calls that do not come through.

How to change snooze time on iPhone

On iOS 26 and later, each alarm has its own snooze length. Open the Clock app, tap Alarms, tap the alarm or the plus button for a new one, make sure Snooze is on, tap Snooze Duration and choose anything from 1 to 15 minutes. Tap Save. Snooze Duration is set per alarm, so change it on each one.

On iOS 18 and earlier, the snooze is fixed at 9 minutes and cannot be changed. The workaround is to turn Snooze off on your main alarm and add extra alarms a few minutes apart, such as 5 minutes. If you are not sure which version you have, open Settings › General › About, or see how to update your iPhone. To change what an alarm sounds like, read how to change the alarm sound.

Why your iPhone sound settings seem not to work

1. Check the silent switch or Silent mode first. It changes vibration and ringer behavior, even if your sound choices are right.
2. Check Focus. A scheduled Focus can mute apps without telling you.
3. Test with a contact that has no custom tone, since a custom tone set to None overrides your default.
4. Restart the iPhone and install the latest update.
5. If every sound is distorted or silent, even in music, the speaker may be blocked or damaged. A repair quote is worth getting before you replace the phone.

Other sound and haptic switches worth knowing

Beyond tones, Settings › Sounds & Haptics holds a few switches that explain a lot of puzzling behavior. The Ringer and Alerts slider sets the volume for calls and alerts. Change with Buttons decides whether the volume buttons also move that slider, which is why the ringer can be too quiet even when media volume is high. System Haptics turns the small taps you feel on the screen on or off. Keyboard Feedback lets you add click sounds or a tap to typing, and Lock Sound plays a sound when you lock the phone.

Most iPhones have a Ring/Silent switch on the side. Newer models with an Action button can use it for Silent mode instead. When Silent mode is on, the phone stays quiet for calls and alerts, but it can still vibrate if Haptics allows it. If you wear AirPods or another Bluetooth device, sound may play there instead of the phone, so disconnect them for a test call.

Which sound problem do you have?

• Calls are silent: check Silent mode, the Ringer and Alerts slider, Focus and any Bluetooth device.
• Texts are silent: check the Text Tone, the chat's Hide Alerts setting and the app's notification settings.
• One person sounds different or silent: check their contact card for a custom tone or vibration set to None.
• The phone rings too long or too short: that is a carrier setting, so use the voicemail code section above.
• The alarm snooze is too long: set the Snooze Duration on iOS 26, or add extra alarms on older versions.
