WhatsApp calls have become an indispensable part of our daily lives for keeping in touch with our loved ones. However, it can be frustrating to encounter problems with calls that don’t work. This article aims to guide you through the steps to effectively resolve these issues and get back to a smooth calling experience on WhatsApp.

Check your Internet connection

The first step to resolving WhatsApp calling issues is to check your internet connection. Make sure you have a stable Wi-Fi connection or a good cellular signal. Weak connections can lead to dropped calls or poor quality.

Update WhatsApp

WhatsApp regularly releases updates to improve performance and fix bugs. Make sure you have the latest version of the application installed on your phone. This could solve call problems.

Check application permissions

Make sure WhatsApp has all the necessary permissions to access your phone’s microphone and camera. If these permissions are disabled, calls will not work properly.

Restart application and phone


Sometimes a simple action like restarting the application or your phone can solve temporary problems. This helps to update settings and eliminate any bugs.

Check storage space

A lack of storage space on your phone can cause problems with the app’s operation. Make sure you have enough space available to ensure WhatsApp calls work properly.

Check network settings

Make sure your network is not blocking WhatsApp calls. Some networks may restrict the use of VoIP services, which affects WhatsApp calls. Checking if your network settings are blocking WhatsApp calls may require a few diagnostic steps. Here’s a guide to help you do this:

Wi-Fi/Mobile Data: First, make sure you’re connected to a stable Wi-Fi network or that your mobile data is turned on. Weak connections can lead to interruptions in calls.

Check firewall settings: Some networks have firewalls or restrictions that may block VoIP services such as WhatsApp. If you’re on a Wi-Fi network, check your router settings to make sure they don’t prohibit VoIP services.

VPN: If you are using a VPN, this may affect WhatsApp calls. Make sure the VPN allows VoIP calls. You can also try temporarily disabling the VPN to see if that solves the problem.


UDP port: WhatsApp uses the User Datagram Protocol (UDP) port for calls. Some networks may block this port, causing problems with calls. Check with your network provider or router to make sure the UDP port is open.

Proxy: If you are using a proxy, this can also interfere with WhatsApp calls. Make sure the proxy is not blocking the traffic needed for VoIP calls.

Internet Service Provider (ISP) settings: Some ISPs have specific restrictions on VoIP services. Contact your ISP to see if they block WhatsApp related traffic.


Test on another network: If possible, try connecting your phone to another network (for example, a different mobile network or a public Wi-Fi network). If calls work on a different network, this probably indicates a problem specific to your original network.

Update router firmware: If you are on a home Wi-Fi network, make sure your router firmware is up to date. Updates can resolve compatibility problems.

Uninstall and reinstall WhatsApp

If all the above steps fail, consider uninstalling the application and reinstalling it. This may resolve issues related to corrupted files or installation errors.
