Why don't calls work in WhatsApp on the phone - briefly?
If you are unable to make calls using WhatsApp on your phone, it is likely due to one of two primary reasons: either your internet connection is unstable or insufficient, or the app has not been updated to the latest version.
Why don't calls work in WhatsApp on the phone - in detail?
There could be several reasons why WhatsApp calls are not working on your phone. Here are some detailed explanations:
-
Internet Connectivity Issues: WhatsApp calls require a stable internet connection, either via Wi-Fi or mobile data. If your internet is slow, unstable, or not connected at all, you won't be able to make or receive calls. To resolve this, ensure that your Wi-Fi is working properly or switch to mobile data if available.
-
Outdated App Version: WhatsApp frequently updates its app to fix bugs and improve functionality. If your WhatsApp version is outdated, you might face issues with call features. Check for updates in the Google Play Store (for Android) or Apple App Store (for iOS), and install any available updates.
-
Phone Permissions: For WhatsApp calls to work, the app needs certain permissions on your phone, such as access to your microphone, camera, and contacts. If these permissions are not granted, calls may not function properly. Go to your phone's settings, find WhatsApp in the list of apps, and ensure that all necessary permissions are enabled.
-
Network Restrictions: Some mobile network providers restrict or block VoIP (Voice over Internet Protocol) services like WhatsApp calls. This can happen due to technical limitations or commercial reasons. Contact your service provider to check if there are any restrictions on your plan and if they can be lifted.
-
WhatsApp Server Issues: Occasionally, WhatsApp's servers may experience downtime or technical issues that affect call functionality. These problems are usually temporary and resolve themselves within a few hours. You can check the status of WhatsApp's servers using online tools or wait for an official announcement from the company.
-
Phone Settings: Certain phone settings, such as power-saving mode or data saver features, can interfere with WhatsApp calls. These modes often restrict background data usage, which is essential for receiving calls. Disable these settings temporarily to see if it resolves the issue.
-
Account Issues: If your WhatsApp account is banned, suspended, or having other issues, you might not be able to make or receive calls. Check your account status and ensure that there are no ongoing problems with your WhatsApp profile.
-
Hardware Problems: In rare cases, hardware issues with your phone's microphone, speaker, or network connectivity components can cause WhatsApp call problems. If you suspect a hardware issue, consider getting your device checked by a professional technician.
