WhatsApp Messenger can stop working for several reasons. This may be due to problems with the service and its servers or problems with your connection or device. To verify that the strange behavior of WhatsApp is due to server problems, you will have to resort to external services such as DownDetector. As for the possible causes that may be due to your device, we can find the following:
- The Internet connection is unstable.
- The SIM card is defective.
- Our operator is having trouble providing us with a mobile internet service.
- The WiFi connectivity of our device does not work properly.
- We have an old version of WhatsApp installed, that we have not updated.
- We have little free storage space.
What can you do to check if the service is restored? You can try any of the possibilities below:
- Make sure your mobile data connection is on. If it is on, turn it off and reconnect it to restart it.
- Restart your cell phone. It would not be the first time that a problem with Android is solved in this way.
- Restart your router according to the instructions of the manufacturer (or the operator, if supplied).
- Remove and reinsert the SIM card into your phone.
- Check the version of WhatsApp for updates.
- Try to free up storage space by deleting all the files you do not need.
- Uninstall and reinstall WhatsApp. If you are forced to do this, have a backup of your conversations ready to restore them.
Also, do not pass up any other misdirection that could be leaving you offline. Check that you have not inadvertently deactivated the data connection, that you have not blocked or muted contacts or groups, that you have correctly saved the number of the person you want to talk to, the notification settings on your mobile, and such. These little details might give you the feeling that there is a problem.
