This issue often arises if the carrier doesn’t support WiFi calling for the Galaxy Z Flip 4 or if there’s a software issue with the device’s current Android system. 

In this guide, we will address every possible cause of this issue and provide you with 5 solutions to fix it.

After enabling it, you may need to set up WiFi calling for your device by following the on-screen instructions. Once done, restart your device to apply the changes.

Fix 02: Check If Your Carrier Supports WiFi Calling on Z Flip 4 Model

One of the reasons you are experiencing issues with WiFi calling on your Samsung Z Flip 4 could be due to your network provider or carrier not supporting this feature for your specific device model.

To confirm this, contact your network provider directly and inquire if they support WiFi calling for the Samsung Galaxy Z Flip 4. Make sure to specify the exact model of your device to avoid any confusion.

It’s worth noting that several users with AT&T as their carrier have reported that this provider doesn’t fully support WiFi calling for the Z Flip 4. If your carrier confirms that they don’t support this feature for your device, consider switching to a different network provider that does.

Once you’ve confirmed that your carrier supports WiFi calling for your device, and you’re still experiencing issues, proceed to the next fix.
