iPhone iOS 12 Text Notification Fix: 7 Steps That Work

Guide 10-21455 · Updated · Step by step

If your iPhone running iOS 12 isn’t showing text message notifications, the fix usually involves checking Notification settings, Do Not Disturb, and Focus modes, then restarting or resetting specific settings. This guide walks through the most common causes and solutions, from simple toggles to deeper system resets, so you can get alerts working again.

Why Notifications Stop on iOS 12

iOS 12 introduced grouped notifications and improved Do Not Disturb options, but it also brought new ways alerts can get silenced. The most common reasons for missing text notifications include:

  • Notification settings for Messages are turned off or set to "Deliver to Notification Center" instead of banners.
  • Do Not Disturb is enabled, either manually or scheduled, and it’s set to silence all alerts.
  • Focus mode (introduced in iOS 15, but similar behavior exists in iOS 12’s Do Not Disturb) is blocking notifications.
  • The iPhone is in Silent mode or the volume is turned down, so banners appear but no sound plays.
  • A software glitch or outdated carrier settings is interfering with notification delivery.

Before diving into fixes, check if the issue affects only text messages or all notifications. This helps narrow down whether it’s a Messages-specific setting or a system-wide problem.

Step 1: Check Notification Settings for Messages

Open Settings > Notifications > Messages. Make sure Allow Notifications is toggled on. Then check:

  • Alert style: Choose Banners or Alerts (not "None"). Banners appear temporarily at the top; Alerts stay until dismissed.
  • Sounds: Ensure a sound is selected, not "None".
  • Badge App Icon: Turn on if you want the red badge count.
  • Show in Notification Center: Keep on so missed alerts appear in the list.

If these were already set correctly, toggle Allow Notifications off and on again. This often forces the system to re-register the app and can clear a stuck state.

Step 2: Disable Do Not Disturb and Focus Modes

Do Not Disturb is a frequent culprit. Swipe down from the top-right corner to open Control Center (or swipe up from the bottom on older iPhones). Look for the crescent moon icon. If it’s highlighted, tap it to turn off Do Not Disturb.

Also check Settings > Do Not Disturb:

  • Scheduled: If a schedule is set, it might be active during certain hours. Turn it off or adjust the times.
  • Allow Calls From: If set to "No One" or a specific group, calls and messages from others will be silenced.
  • Repeated Calls: This feature allows a second call from the same number within 3 minutes to ring, but it doesn’t affect texts.

If you’re on a newer iOS version, Focus modes (like Personal, Sleep, or Work) can also block notifications. Check Settings > Focus and ensure none are active or scheduled.

Step 3: Check Silent Mode and Volume

Even if banners appear, you might not hear the alert if the phone is on Silent. The physical mute switch is on the left side of the iPhone. If you see an orange strip, it’s on Silent. Flip it up to turn off Silent mode.

Also press the volume up button to ensure the ringer volume isn’t at zero. You can also check Settings > Sounds & Haptics and drag the Ringer and Alerts slider to a comfortable level. Make sure Change with Buttons is on if you want the physical volume buttons to control the ringer.

Step 4: Restart Your iPhone

A simple restart can resolve many notification glitches. To restart an iPhone with Face ID: press and hold the side button and either volume button until the power off slider appears. Drag the slider, wait 30 seconds, then press and hold the side button until the Apple logo appears.

For iPhones with a Home button: press and hold the top or side button until the slider appears, then power off and back on. This clears temporary system files and can re-establish notification services.

Step 5: Update Carrier Settings and iOS

Carrier settings updates can fix issues with text message delivery. Go to Settings > General > About. If an update is available, a pop-up will appear. Tap Update.

Also check for iOS updates: Settings > General &strong> Software Update. If iOS 12 is installed, you might be able to update to a later version (like iOS 15 or 16) if your device supports it. Newer versions have improved notification management and bug fixes. If you’re stuck on iOS 12 because of an older device, these steps are still applicable, but some settings may look slightly different.

Step 6: Reset All Settings

If nothing else works, resetting all settings can clear underlying configuration issues without erasing your data. Go to Settings > General > Reset > Reset All Settings. This resets Wi-Fi passwords, wallpapers, and notification preferences to defaults, but it doesn’t delete photos, apps, or messages. After the reset, you’ll need to re-enable notifications for Messages and other apps.

This is a more drastic step, so try it after other fixes fail. It often resolves persistent notification problems caused by corrupted settings.

Step 7: Check for iMessage vs SMS Issues

If you’re not getting notifications for iMessages but are for SMS (green bubbles), the problem might be with your Apple ID or network. Go to Settings > Messages and ensure iMessage is toggled on. If it’s on, toggle it off and on again. Then tap Send & Receive to verify your Apple ID is signed in.

Also check Settings > FaceTime and make sure it’s active, as iMessage and FaceTime share the same backend. If you’re still not receiving iMessages, sign out of your Apple ID entirely (Settings > your name > Sign Out), restart, and sign back in. This re-authenticates your device with Apple’s servers.

Frequently Asked Questions

Why do I get notifications on my iPad but not my iPhone?

This usually happens because the iPhone is set to not allow notifications while the iPad is. Check the notification settings on the iPhone as described in Step 1. Also, if you have an Apple Watch, it might be taking over notifications when the phone is locked. Go to Watch app > Notifications and ensure "Mirror iPhone" is selected.

Will resetting all settings delete my messages?

No. Reset All Settings only resets system settings like Wi-Fi, Bluetooth, and notification preferences. It does not delete your contacts, messages, photos, or apps. However, it’s always a good idea to back up your iPhone before performing any reset.

Can a specific contact be muted?

Yes. Open the Messages app, find the conversation, and swipe left on it. Tap the bell icon to unmute if it’s muted. Also, when viewing a conversation, tap the contact’s name at the top and check if "Hide Alerts" is toggled on. If it is, turn it off.

Why are my notifications silent even though the volume is up?

Check the sound setting for Messages specifically. Go to Settings > Notifications > Messages > Sounds and make sure it’s not set to "None." Also, ensure the ringer volume is not at zero by pressing the volume up button while on the Home screen. The "Change with Buttons" setting in Sounds & Haptics controls this.

I have iOS 12 and don’t see Focus mode. What should I do?

Focus mode was introduced in iOS 15, so it won’t appear on iOS 12. Instead, use Do Not Disturb as described in Step 2. The steps for notification settings and resetting settings are the same across versions, so follow those for iOS 12.

Is there a way to force a notification for a test?

Yes. Ask a friend to send you a text, or send yourself a message from another device. If you have an iPad or Mac, you can send an iMessage to your iPhone. Alternatively, use the Messages app on your iPhone to send a text to your own number (if your carrier supports it). This helps confirm if the fix worked.
