In general, WhatsApp voice and video calls work almost flawlessly on any device. However, some users have reported that they are facing the issue of WhatsApp video calls not working on iPhone.
Fortunately, in most cases, the problem can be fixed by checking WhatsApp permissions and other methods as given below.
1. Check WhatsApp permissions
The problem of WhatsApp video calls not working on iPhone is usually because WhatsApp is denied permission to access the camera on your device (during the setup process or later).
Open settings > scroll down and tap Whatsapp > On the next screen, move the switch next to microphone and camera to ON Position.
Once WhatsApp can access the camera and microphone, you should be able to make voice and video calls on WhatsApp.
2. Update WhatsApp
Before proceeding to other troubleshooting steps, make sure you have the latest version of WhatsApp installed on your iPhone.
Open app store > search Whatsapp > Tap on the next screen To update Option next to WhatsApp Messenger.
Note: The update option is only available when an update is available for WhatsApp.
3. Check your internet connection
Compared to text messages and voice calls, WhatsApp video calls require a stable and strong network connection to work properly.
Therefore, check the network connection strength on your iPhone and try switching to the 5GHz WiFi network by going to settings > Wireless Internet access > select 5G network in the My Networks section (if available).
Note: In the case of a cellular network, 5G is only available if provided by your service provider.
4. Check the privacy restrictions
Make sure the privacy settings on your iPhone do not prevent WhatsApp from using the camera on your iPhone.
Go to settings > privacy > camera > Move the switch next to Whatsapp to ON Position.
Proceed in a similar way settings > privacy > microphone and move the switch next to Whatsapp to ON Position.
5. Check Screen Time Limits
If you use Screen Time, you may have set a time limit on WhatsApp.
Go to settings > screen time > app limits > Whatsapp > Disable on the next screen app limit for WhatsApp by moving the switch to OUT Position.
If you scroll down on the same screen, you will find the options to edit or delete the app limit setting for WhatsApp.
6. Allow WhatsApp to use mobile data
If you’re trying to make a WhatsApp video call using mobile data, you’ll need to give WhatsApp cellular network access.
Go to settings > cellular > Move the switch next to Whatsapp to ON Position.
Note: The default setting in WhatsApp is to use the free WiFi network.
7. Disable low data mode
WhatsApp video calls may not work properly if your iPhone is set to low data mode. So go to settings > cellular > Cellular data options and disable Low data mode.
After disabling low data mode, you should be able to make WhatsApp video calls.
8. Enable the use of background data
Enabling this option allows you to receive WhatsApp voice and video calls while you are not actively using WhatsApp.
Go to settings > Whatsapp > Activate Update background app.
Note: If you’re on a limited cellular data plan, you can reduce cellular data usage on your iPhone by leaving this option turned off.
9. Reset network settings
Make a note of your WiFi network password and follow the steps below to reset network settings on your iPhone.
Go to settings > General > Transfer or reset iPhone > Reset to default > Select in the pop-up window Reset network settings Possibility.
In the confirmation popup, select the Reset to default option to confirm.
10. Reinstall WhatsApp
