Perform Basic Check for Your Android Device
1. Make sure that your phone has a strong network connection. Open a webpage in phone browser and see if the page loads smoothly.
2. Restart your Android phone.
3. Reboot your Wi-Fi router.
4. On Google Play store, check if there is update for WhatsApp. If it is, get the update. The update might fix some bugs in the app.
Adjust Your Phone's Settings
1. Open Settings app on your Android, tap "More" > "Airplane mode". Toggle the button off and back to on.
2. If you are using Wi-Fi, go to "Settings" > "Wi-Fi" and turn Wi-Fi off and on again.
3. Tap "Wi-Fi" > menu icon > "Advanced" and choose to keep Wi-Fi on during sleep mode.
4. If you are using cellular data, go to "Settings" > "Data Usage" and toggle off and on "Cellular data".
5. Tap "Data usage" > "Network restrictions" and make sure that no Wi-Fi network is restricted.
Reconnect to the Wi-Fi
1. Launch Settings app on your phone;
2. Choose "Wi-Fi";
3. Tap on the Wi-Fi network that you are unable to use and choose "forget";
4. Reconnect to the Wi-Fi and enter the password again. (If you could not see the Wi-Fi, see how to enable Wi-Fi).
Log in Captive Wi-Fi Network
If you are using a captive Wi-Fi network, which is often seen in coffee house, library, etc., make sure that you have logged in on your phone browser.
If WhatsApp works on Wi-Fi network but not cellular data network, or other applications can all work on the data network except WhatsApp, you need to contact with your carrier and make sure your access point names (APN) has set up correctly. Sometimes, it could be your carrier that set up your wireless access points to block certain chat applications. Or internet APN is missing in your APN settings. Just contact your network provider and they will walk you through the set-up.
