Troubleshooting voice and video calls not working on WhatsApp
Applies to: WhatsApp Messenger (Android, iOS, WhatsApp Web/Desktop with companion device)
Last updated: September 2025
Problem
WhatsApp voice or video calls fail to connect, drop frequently, or have poor quality (no sound, frozen video, or one-way audio). This can happen due to weak internet, device settings, or app restrictions.
Solution
Fixing WhatsApp calling issues requires checking your internet, permissions, and device compatibility.
Step-by-step Instructions
Step 1: Check your internet connection
- Ensure you have a stable Wi-Fi or 4G/5G connection.
- Test speed: calls need at least 100 kbps upload/download.
- Switch between Wi-Fi and mobile data to compare performance.
Step 2: Restart your phone
- A quick reboot refreshes network and system processes.
Step 3: Check WhatsApp permissions
- Android:
- Settings > Apps > WhatsApp > Permissions.
- Ensure Microphone and Camera are allowed.
- iPhone:
- Settings > WhatsApp.
- Enable Microphone and Camera toggles.
Step 4: Update WhatsApp and system software
- Outdated versions may have call-related bugs.
- Update via Play Store or App Store.
- Update your OS for better compatibility.
Step 5: Disable low data or battery saver modes
- Android: Settings > Battery > Battery Saver → Turn off.
- iPhone: Settings > Battery > Low Power Mode → Off.
- Data saver can also restrict calls — disable if active.
Step 6: Test WhatsApp Web/Desktop
- Remember: voice/video calls only work on your phone, not the web client (as of 2025).
- On WhatsApp Desktop app (Windows/Mac), calls work if your phone stays connected.
Optional Methods or Tools
- Use a different Wi-Fi network if yours blocks VoIP (common in workplaces or public places).
- Restart your router to refresh the connection.
- Disable VPNs or Proxies, which can interfere with VoIP traffic.
Best Practices / Tips
- Use headphones or Bluetooth earbuds for clearer audio.
- Close background apps that might consume bandwidth during calls.
- For best quality, use Wi-Fi with strong signal instead of mobile data.
- Check WhatsApp System Status if global outages occur.
