WhatsApp is not working

I can't connect to WhatsApp or WhatsApp not working

WhatsApp connection problems are usually caused by your Wi-Fi or network data connection. If you aren't able to send a message, here are a few solutions:

• Make sure your phone is switched on (one for the newbies).
• Install the latest version of the app from the Play Store (link above).
• Check your internet connection, Wifi or 3G (in Settings > Wireless and Network).
• Make sure that a Task Killer app isn't affecting WhatsApp.
• Empty the app cache (Settings > Applications > WhatsApp > Clear Cache).
• Finally, the most extreme solution: uninstall the app and then reinstall it.

Sometimes, even the mighty WhatsApp experiences server issues. If you think WhatsApp isn't working because the service is down, then head over to the WhatsApp Status Twitter account, where outage updates are provided.
