How to Fix WhatsApp Not Sending Messages

When WhatsApp shows one grey tick, your message is not reaching the server. This is almost always a connection or account issue.

Likely causes

• No internet connection or weak signal
• WhatsApp servers down
• Phone date and time set incorrectly
• WhatsApp needs an update
• Account banned or blocked

Step-by-step fix

1. 1
   Check your internet connection

   Open a browser and load a webpage. If the internet is not working, fix that first.

2. 2
   Toggle Airplane mode

   Turn Airplane mode on for 10 seconds, then off. This refreshes your mobile data or WiFi connection.

3. 3
   Check WhatsApp server status

   Visit downdetector.co.uk/status/whatsapp to check for outages. If servers are down, wait and try again.

4. 4
   Check your phone date and time

   Go to Settings → General management → Date and time → enable "Automatic date and time". Incorrect time prevents WhatsApp from connecting.

5. 5
   Update WhatsApp

   Open the App Store or Google Play and update WhatsApp to the latest version.

6. 6
   Clear WhatsApp cache (Android)

   Settings → Apps → WhatsApp → Storage → Clear Cache. This does not delete your messages.
