WhatsApp is one of the most used programs for sending messages, video calls, and voice calls. Sometimes it may stop working after using the program for a while. This can have various reasons. If you are having trouble sending messages or your WhatsApp app has crashed, this article is good for you. Fortunately, in most cases, you can solve this problem quickly. We’ll give you ten methods to fix your WhatsApp when it is not working on your phone, in the following.

Note: The steps mentioned in different methods may be slightly different on your phone. In general, the steps are similar, but the names of each option may be a little different on your phone.

Check your phone’s internet connection

The first thing you need to use WhatsApp and send messages through it is an internet connection. If your phone’s internet connection is off, turn it on first. Make sure you see a Wi-Fi or cellular internet signal at the top of the phone screen. If the Internet connection signal does not appear, a quick way to solve this problem is to turn on airplane mode and turn it off after a few seconds. To make sure that your phone is connected to the Internet, you can use your browser or another app that requires the Internet. If they had no problem with their internet connection, but WhatsApp still is not working, the cause of this issue is not your internet connection.

But if your mobile internet is not working for all apps, you should solve your internet connection problem.

If you use Wi-Fi, the first solution is to turn the router off and on. If the problem still exists, check the connection of its wires or ask an expert to help you solve it.

If you use cellular data, go to the following path and turn on mobile data:

Settings > Network & Internet > SIMs

And turn on mobile data.

Pay attention that if you are not in your country, also toggle roaming on (this may incur extra charges).

Restart your phone

Some of the problems we face with some apps are because of some little bugs. One of the fastest and easiest ways to fix them is to restart the phone. Restarting the phone can solve many of your problems. So, before trying other methods, turn off your phone and turn it on again. 

Restarting the phone can be different depending on the brand and model of the phone:

  2. After several options disappear on the screen, tap Restart or Reboot.
