How to Fix WhatsApp Not Sending Messages (Android & iPhone)

If your WhatsApp messages stay on one tick or do not send at all, don’t worry—this is a very common issue. It usually comes from internet problems, app bugs, or device settings. Here are the best ways to fix it fast.

1. Check Your Internet Connection

WhatsApp requires a stable connection. Make sure:

• Your Wi-Fi or mobile data is activated
• You are not in airplane mode
• You switch between Wi-Fi and data to test

2. Restart the App

Close WhatsApp completely and reopen it. This resets the connection with WhatsApp servers.

3. Enable Background Data

If background data is disabled, messages cannot send in the background.

• Go to Settings › Apps › WhatsApp
• Tap Mobile Data
• Enable Allow Background Data Usage

4. Clear Cache (Android Only)

• Settings › Apps › WhatsApp
• Storage
• Tap Clear Cache

5. Check WhatsApp Server Status

Sometimes WhatsApp servers go down globally. In that case, you just need to wait until it is fixed.

6. Update WhatsApp

Outdated versions may have bugs. Update the app from Google Play or the App Store.

Conclusion

With these solutions, your WhatsApp messages should send normally again. If the problem continues, consider reinstalling the app.
