At least on iOS, internet call is treated basically the same as cellular, showing a splash caller screen and ringing if not on silent. This means that it's trivial to setup phone in such a way that no notification gets through but calls do, even with sound.

The point being made above is that if data is turned off, you can no longer receive calls made over WhatsApp.

Yup.

My intention is to intentionally block whatsapp calls.

And to use the oldskool telephone for emergencies.

I could have communicated it more clearly.

Yes, I was not clear too - what I mean is that my family won't be able to get in touch.

This is also true on Android.
