The most common reason: notification settings are turned off for your messaging app
Your phone receives the text but does not alert you because the app that handles texts — usually Messages on Android or iMessage on iPhone — has notifications disabled. This happens most often after a software update, when you accidentally swipe away a notification and choose "turn off notifications," or when someone else used your phone and changed the setting.
On iPhone, go to Settings > Notifications > Messages and check that "Allow Notifications" is turned on. On Android, go to Settings > Apps > Messages (or whatever your default texting app is called) > Notifications and make sure notifications are enabled there. The exact path varies by phone model and Android version, but the principle is the same: find the app, find notifications, turn them on.
Key Takeaways
- Check your messaging app's notification settings first — they may be off even though you are receiving texts normally.
- Your phone's Do Not Disturb or Focus mode can silence text alerts while still delivering the messages.
- Some phones have a separate "notification volume" that is different from call volume, and it may be muted.
- If you use a messaging app that is not your phone's default (like WhatsApp or Signal), you need to check that app's settings separately.
- Carrier-level blocking or filtering by your phone company can prevent notifications without blocking the actual text.
Do Not Disturb or Focus mode is silencing notifications without deleting messages
Both iPhone and Android have a feature that stops your phone from alerting you to anything — calls, texts, emails — while still storing the messages so you can read them later. On iPhone this is called Focus mode (or Do Not Disturb on older versions). On Android it is called Do Not Disturb.
Check whether this is on. On iPhone, swipe down from the top right corner and look for a moon icon or the word "Focus" — if it is highlighted, tap it to turn it off. On Android, swipe down twice from the top and look for "Do Not Disturb" — if it is on, tap it to turn it off. You will still receive the texts; you just were not being notified.
Your notification volume is separate from your call volume and may be muted
Many phones have two different volume controls: one for calls and one for notifications. If your notification volume is turned all the way down, you will not hear or feel an alert for texts even though notifications are technically on.
On iPhone, go to Settings > Sounds & Haptics and check that the volume slider under "Ringer and Alerts" is not all the way down. On Android, press the volume button on the side of your phone and look at what appears on screen — if it shows notification volume, adjust it up. Some Android phones also have a separate notification volume slider in Settings > Sound.
You are using a messaging app that is not your phone's default
If you text through WhatsApp, Signal, Telegram, or another third-party app instead of your phone's built-in Messages app, you need to check that app's notification settings, not your phone's main settings. Your phone's Messages app can have notifications on while WhatsApp has them off, or vice versa.
Open the app you actually use for texting. Look for Settings or Preferences (usually a gear icon). Find Notifications and make sure they are enabled. Each app stores this setting in a different place, so if you cannot find it, search the app's help section for "notifications."
Your carrier or phone company is filtering messages before they reach you
Some phone companies offer spam-filtering services that can block texts from reaching you at all, or block the notification while the message sits in a spam folder. Verizon Call Filter, AT&T Call Protect, and T-Mobile Scam Shield are the most common. If you have one of these services turned on, it may be filtering out legitimate texts.
Call your phone company's customer service number (usually on your bill) and ask whether message filtering is on and whether any recent texts have been blocked. They can see what was filtered and restore it if needed. You can also turn off the filtering service in your phone's settings, though this means you will get more spam.
A recent software update changed your notification settings
When your phone updates to a new version of iOS or Android, it sometimes resets notification permissions. Apps that had notifications on may have them turned off after the update, or your Do Not Disturb settings may have changed.
After a major update, go back through your notification settings for the apps you use most. Check Messages, email, and any other app where you need alerts. This is also a good time to review which apps even have permission to send you notifications — you may find apps you forgot about are requesting notification access.
Your phone is in a low-power or battery-saver mode
When your battery is very low, both iPhone and Android can enter a mode that reduces background activity to save power. This can delay or disable notifications. iPhone calls this Low Power Mode; Android calls it Battery Saver or Power Saving Mode.
Check whether this is on. On iPhone, go to Settings > Battery and look for Low Power Mode. On Android, go to Settings > Battery and look for Battery Saver or Power Saving Mode. Turn it off if it is on. Once you charge your phone, this mode usually turns off automatically.
Frequently Asked Questions
How do I know if a text actually reached my phone or if it is stuck somewhere?
Check your Messages app directly — if the text is there, it reached your phone and the issue is notifications. If you do not see it at all, the message may not have been delivered. Ask the person who sent it to try again, or contact your phone company to check whether it was blocked by their filtering service.
Why do I get notifications for some texts but not others?
You may have Do Not Disturb turned on but set to allow texts from certain contacts (like family). Check your Focus or Do Not Disturb settings to see which contacts are allowed through. Or you may have muted notifications from a specific conversation — in Messages, swipe left on a conversation and look for a mute option.
I turned notifications back on but I still do not hear anything — what else could it be?
Make sure your phone's physical mute switch (on the side of iPhone, or volume buttons on Android) is not set to silent. Also check that your phone is not connected to a Bluetooth speaker or headphones that might be playing sound somewhere else. If your phone is plugged in and charging, some phones silence notifications while charging.
Can my phone company block texts without telling me?
Yes. Spam filters can block messages silently, and you will not know unless you ask your carrier to check. Some companies also offer a service where texts from unknown numbers go to a separate folder instead of your main inbox. Call your phone company and ask what filtering is active on your account.
Do I need to restart my phone to fix notification problems?
Sometimes. If you have changed settings and notifications still are not working, try restarting your phone — hold the power button and slide to power off, wait 10 seconds, then turn it back on. This clears temporary glitches that can prevent notifications from working even when settings are correct.
