Troubleshooting WhatsApp not sending or receiving messages
Applies to: WhatsApp Messenger (Android, iOS, WhatsApp Web/Desktop)
Last updated: September 2025
Problem
Messages on WhatsApp are stuck with a clock icon (not sent), one gray tick (sent but not delivered), or not arriving at all. This can be caused by network problems, app restrictions, or issues with the recipient’s device.
Solution
Most delivery problems can be resolved by checking your internet connection, WhatsApp permissions, and ensuring the recipient’s phone is active and connected.
Step-by-step Instructions
Step 1: Verify your internet connection
- Test other apps (e.g., browser, YouTube).
- If not working, switch between Wi-Fi and mobile data.
- Restart your router or modem if using Wi-Fi.
Step 2: Restart your phone
- Rebooting clears temporary system or network glitches.
Step 3: Check recipient availability
- If the recipient’s phone is off, out of signal, or their WhatsApp is uninstalled, your message will remain undelivered.
Step 4: Check WhatsApp permissions
- Android: Settings > Apps > WhatsApp > Permissions → Allow Internet, SMS (if required), and Background data.
- iPhone: Settings > WhatsApp → Enable Mobile Data and Background App Refresh.
Step 5: Update or reinstall WhatsApp
- Open the App Store or Google Play Store.
- Tap Update.
- If issues persist, reinstall WhatsApp.
Step 6: For WhatsApp Web/Desktop
- Ensure your phone is online and WhatsApp is running in the background.
- Refresh the browser or reconnect by scanning the QR code.
Optional Methods or Tools
- Disable any active VPN or Proxy, as these can block WhatsApp traffic.
- Check firewall/antivirus settings if using WhatsApp Web/Desktop.
- Visit WhatsApp Status to confirm if servers are down.
Best Practices / Tips
- Keep WhatsApp updated to avoid delivery bugs.
- Ensure enough phone storage — a full device can block message syncing.
- Avoid using task-killer or battery-saver apps that block background processes.
- Remember: if you’re blocked by the recipient, your messages will never show double ticks.
