Notifications stop showing up when one of four settings is turned off
Your iPhone notifications vanish for one reason: a setting somewhere is blocking them. The block happens at one of four points — the app itself, the notification center, Do Not Disturb, or Focus modes — and you need to check each one because a notification can pass through three of them and still get stopped at the fourth.
The fastest way to find the problem is to pick one app that should be notifying you and trace it through all four checkpoints. Start with an app you know sends notifications, like Messages or Mail, because you can test whether the fix worked when ready.
Most people find the problem in the first two places: the app's own notification settings, or the master notification switch in Settings. But if those are on, the culprit is usually Do Not Disturb or a Focus mode you forgot about.
Key Takeaways
- Check the app's own notification settings first — go to Settings, find the app name, and confirm notifications are turned on there.
- Verify the app has permission to send notifications in Settings > Notifications, where you can see every app's status at a glance.
- Do Not Disturb and Focus modes silence notifications even when the app is allowed to send them, so check both if the first two steps don't work.
- Some notifications are silenced because you swiped them away or changed their delivery style to Quiet, which hides them from your lock screen.
- If notifications work on WiFi but not cellular, or vice versa, the problem is usually your internet connection, not your notification settings.
Check the app's own notification settings first
Every app has its own notification controls inside the app itself, separate from iPhone's system settings. An app can be allowed to send notifications at the system level but have notifications turned off inside the app.
Open the app that should be notifying you. Look for Settings, Preferences, or a gear icon — the location varies by app. Search for a Notifications or Alerts section. If notifications are toggled off there, turn them on. Close the app completely and wait a few minutes to see if a notification arrives.
For apps like Mail, Messages, and Calendar, also check whether you have filtered notifications. Mail lets you turn off notifications for certain mailboxes. Messages lets you mute specific conversations. Calendar lets you silence notifications for specific calendars. If you only see notifications from some senders or some calendars, you have probably muted the others inside the app.
Confirm the app has permission in iPhone Settings
Open Settings on your iPhone. Scroll down and tap Notifications. You will see a list of every app on your phone. Find the app that is not notifying you and tap it.
At the top of that app's notification settings, you will see a toggle for Allow Notifications. If it is off (gray), tap it to turn it on (green). Below that, make sure Sounds is on, Badges is on, and Banners is on — or at minimum, that the delivery style is not set to None.
The Delivery Style setting controls how the notification reaches you. when ready means it shows up right away. Scheduled means it waits until a time you set. Quiet means it goes to the notification center but does not appear on your lock screen or send a sound. If you see Quiet selected, change it to when ready.
After you change these settings, go back to the app and trigger a notification if you can — send yourself a test message, or create a calendar event for right now. The notification should appear within a few seconds.
Turn off Do Not Disturb if it is on
Do Not Disturb is a master switch that silences all notifications, calls, and alerts, regardless of what the apps are allowed to do. You can turn it on manually, or it can turn on automatically at a time you set.
Swipe down from the top-right corner of your screen to open Control Center. Look for the Do Not Disturb icon — it looks like a circle with a line through it. If it is highlighted in purple or blue, Do Not Disturb is on. Tap it to turn it off.
If Do Not Disturb keeps turning itself back on, you have a schedule set. Go to Settings > Focus > Do Not Disturb and look at the bottom of the screen. If you see a time range listed under Scheduled, tap Edit and turn off the schedule, or change the times so Do Not Disturb does not set up during the hours you need notifications.
Check your Focus modes
Focus modes are similar to Do Not Disturb but more specific. You can create a Focus for Work, Sleep, Driving, or custom situations, and each one can silence different apps. A Focus can be on without you realizing it, especially if you have one set to turn on automatically at certain times.
Swipe down from the top-right corner to open Control Center. Look for any Focus icon that is highlighted — it might say Work, Sleep, Driving, or a custom name. If one is on, tap it to turn it off.
If a Focus keeps turning on by itself, go to Settings > Focus and tap the one that is active. Scroll down and look for Scheduled. If a time range is listed, that Focus is set to turn on automatically. Tap Edit and turn off the schedule, or adjust the times.
You can also check which apps are allowed to notify you inside each Focus. When a Focus is on, only apps you have allowed will send notifications. If an app is not on the allowed list for an active Focus, you will not see its notifications even if the app is allowed at the system level. Tap the Focus name, then tap Apps, and make sure the app you need is listed under Allowed Apps.
Verify your internet connection
Some notifications require an internet connection to reach your phone. If you are on WiFi but notifications are not coming through, try turning WiFi off and using cellular data instead. If you are on cellular and notifications are not arriving, try switching to WiFi.
If notifications work on one connection but not the other, the problem is usually your internet, not your iPhone. Restart your WiFi router or toggle airplane mode off and on to reset your cellular connection. If the problem persists, contact your internet provider or cellular carrier.
If notifications work on WiFi but never on cellular, check whether your cellular plan includes data. Some plans limit data or require a separate purchase. Without data, your phone cannot receive notifications over cellular even if WiFi is available elsewhere.
Check whether you silenced the notification
If a notification arrived but you swiped it away or tapped Manage, you may have changed how that app sends notifications without realizing it. When you swipe left on a notification and tap the options that appear, you can choose to turn off notifications for that app, or change the delivery to Quiet.
To undo this, go to Settings > Notifications, find the app, and check the Delivery Style. If it says Quiet, change it back to when ready. If Allow Notifications is off, turn it back on.
You can also check your notification history. Swipe down from the top-left corner to open Notification Center. Scroll through the list — if you see notifications from the app you are looking for, they are arriving but may be set to Quiet delivery, which means they are not showing on your lock screen.
Frequently Asked Questions
Why do some notifications show on my lock screen but others only appear in Notification Center?
That is the Quiet delivery style. Go to Settings > Notifications, find the app, and check the Delivery Style. If it says Quiet, change it to when ready. Quiet notifications arrive but do not appear on your lock screen or play a sound — they only show up if you open Notification Center.
My notifications work when I am home but stop when I leave. What is wrong?
Check whether a Focus mode is turning on automatically based on your location. Go to Settings > Focus and look at each Focus you have created. If one says Location under Scheduled, it is turning on when you leave home. Tap it and turn off the location trigger, or remove the app from the allowed list if you want the Focus on but need notifications from that app.
I turned off Do Not Disturb but notifications still are not showing. What else could it be?
Check whether a Focus mode is active instead. Open Control Center and look for any highlighted Focus icon. Also go back to Settings > Notifications and confirm the app itself has Allow Notifications turned on and Delivery Style set to when ready, not Quiet.
Why do I get notifications on my iPad but not my iPhone?
Your devices are signed into the same Apple ID, so notifications are being delivered to both. Check whether Do Not Disturb or a Focus mode is on only on your iPhone. Also check Settings > Notifications on your iPhone to confirm the app is allowed to send notifications there. Your iPad and iPhone can have different notification settings even though they share an Apple ID.
Can I get notifications from one app but not others?
Yes. Go to Settings > Notifications and turn off Allow Notifications for the apps you do not want to hear from. You can also use a Focus mode to allow notifications from only certain apps — create a Focus, go to Apps, and add only the apps you want to notify you while that Focus is on.
