What the WhatsApp Message Symbols Mean
The symbol beside a message can help identify the problem:
- Clock: The message has not left your phone.
- One grey tick: The message has been sent but not delivered to the recipient.
- Two grey ticks: The message has been delivered.
- Two blue ticks: The message has been read, when read receipts are enabled.
If every message shows a clock, focus on your phone and internet connection. If messages work with everyone except one person, the problem may be specific to that contact.
1. Check Your Internet Connection
WhatsApp needs an internet connection to send messages. Your phone can show that it is connected to Wi-Fi even when the actual internet connection is unavailable or unstable.
Try this:
- Open a website in your browser.
- Switch from Wi-Fi to mobile data, or vice versa.
- Turn Airplane Mode on for about 10 seconds, then turn it off.
- Restart your router if you’re using Wi-Fi.
If WhatsApp starts working after switching networks, your original connection was likely the problem.
2. Allow WhatsApp to Use Mobile Data
Your phone may be connected to the internet while WhatsApp is restricted from using data.
Android
Go to:
Settings → Apps → WhatsApp → Mobile Data and Wi-Fi
Make sure mobile and background data are allowed.
iPhone
Go to:
Settings → Mobile Service/Cellular → WhatsApp
Make sure mobile data access is enabled.
3. Update WhatsApp
An outdated version can cause compatibility and software problems.
- Android: Open Google Play Store → Search WhatsApp → Update.
- iPhone: Open App Store → Profile → Update WhatsApp.
If WhatsApp stopped working after a phone software update, checking for a newer WhatsApp version is especially worthwhile.
4. Restart WhatsApp and Your Phone
Temporary software or network processes can sometimes stop working correctly.
Close WhatsApp, restart your phone, wait for it to reconnect to the internet, and send a test message.
This does not delete your WhatsApp chats.
5. Clear WhatsApp Cache on Android
If you’re using Android, damaged temporary files can sometimes affect WhatsApp.
- Open Settings.
- Select Apps.
- Choose WhatsApp.
- Tap Storage.
- Select Clear Cache.
Clearing cache is different from clearing app data. Avoid Clear Data unless you’ve confirmed that your important chats are safely backed up.
6. Disable Battery Restrictions
Some phones restrict WhatsApp’s background activity to save battery. This can cause messages to remain pending until you open the application.
On Android, open:
Settings → Battery → Battery Optimisation → WhatsApp
Choose Unrestricted or the equivalent option available on your device.
On iPhone, review Settings → General → Background App Refresh and make sure WhatsApp is allowed to refresh in the background.
7. Check Your Phone Storage
Very low storage can affect WhatsApp and other applications.
Check your phone’s available storage and remove unnecessary videos, downloads, duplicate files, or unused apps.
You can also manage WhatsApp’s own storage:
WhatsApp → Settings → Storage and Data → Manage Storage
Review large files and delete anything you no longer need.
8. Reset Network Settings
If WhatsApp still cannot send messages, corrupted network settings may be interfering with the connection.
Resetting network settings does not normally delete your photos or apps, but it can remove saved Wi-Fi passwords and other network configurations.
Look for Reset Network Settings in your phone’s Settings. The exact location varies by Android manufacturer and iOS version.
Reconnect to Wi-Fi afterward and test WhatsApp again.
9. Check If WhatsApp Is Down
Sometimes the problem is not your phone. WhatsApp can experience temporary service problems that affect messaging.
Check whether other WhatsApp users are experiencing the same issue or use an outage-monitoring service such as Downdetector’s WhatsApp status page.
If there is a widespread outage, changing your phone settings will not fix the problem. Waiting for the service to recover is usually the appropriate step.
10. Check Whether the Problem Is Only One Contact
If messages send normally to other people but fail with one contact, the problem may not be your WhatsApp installation.
Possible explanations include:
- The person has no internet connection.
- Their phone is switched off.
- They changed their WhatsApp number.
- They no longer use WhatsApp.
- There is a problem specific to that account or conversation.
Send a test message to another contact. If it works, your phone’s WhatsApp connection is probably functioning normally.
Fix WhatsApp Messages Not Sending on iPhone
If you’re using an iPhone, also check Low Data Mode.
Go to:
Settings → Wi-Fi → [your network] → Low Data Mode
Temporarily turn it off and test WhatsApp again.
Also check:
Settings → Mobile Service/Cellular → WhatsApp
Make sure WhatsApp is allowed to use cellular data.
Restarting the iPhone can also refresh its network connection and resolve temporary software problems.
Fix WhatsApp Messages Not Sending on Android
Android users should pay particular attention to:
- Mobile and background data permissions.
- Battery optimisation.
- WhatsApp cache.
- Available storage.
- Network settings.
Different Android manufacturers use different names for these settings, so the exact menu may vary.
Check Your Date and Time
Incorrect date and time settings can sometimes interfere with online services.
Android
Settings → System → Date & Time → Automatic date and time
iPhone
Settings → General → Date & Time → Set Automatically
Use automatic time whenever possible.
Temporarily Disable a VPN
If you use a VPN, turn it off temporarily and test WhatsApp again.
VPNs change how your internet traffic reaches online services, and occasionally a particular connection can cause delays or communication problems.
If WhatsApp works after disabling the VPN, review the VPN’s settings before turning it back on.
What If WhatsApp Messages Are Sending Slowly?
Messages that eventually send but take several minutes usually point toward connection quality rather than a completely broken WhatsApp installation.
Possible causes include:
- Weak mobile signal.
- Congested Wi-Fi.
- Data-saving settings.
- Background restrictions.
- Unstable internet service.
Try switching networks and sending another message.
WhatsApp Messages Not Sending After Changing Phones
If the problem started after moving WhatsApp to a new phone, check:
- Your phone number is correctly verified.
- WhatsApp is updated.
- Your internet connection works.
- WhatsApp has the required permissions.
- Your contacts have synced correctly.
- Your backup has been restored successfully.

Should You Reinstall WhatsApp?
Reinstalling WhatsApp can fix damaged application files, but it should be a last resort.
Before uninstalling:
- Check your last successful backup.
- Confirm your Google Drive or iCloud account.
- Save important files separately if necessary.
- Make sure you can restore your chats.
This is especially important if you use WhatsApp for business, customer communication, or important documents.
Prevent WhatsApp Sending Problems
A few simple habits can reduce future problems:
Keep WhatsApp Updated

Regularly remove unnecessary files from your phone and WhatsApp.
Use Reliable Internet
If you rely on WhatsApp for work or business, having both Wi-Fi and mobile data available can provide a backup connection.
