Fix 1: Restart Your iPhone
Initially, in case you find that you are unable to access the call waiting feature on your iOS 16 device even after performing the above steps, then you must reboot your device.

Fortunately, the fix is pretty straightforward. It may be possible to stop dropping calls just by turning on Airplane mode on your iPhone.

- You will see the Airplane Mode option and tap on it.
- It has a slider beside it that can be used to toggle the service.
