How to restrict Whatsapp calls when on mobile data?

[darael]

Being a low data user, I have a low mobile allowance (500MB/month). So when somebody calls me when I am in area with no Wi-Fi and using mobile data, I reject Whatsapp calls so I don't waste my allowance. Having unlimited minutes means that I am more than happy to call them straight back.

So, is it possible to restrict Whatsapp calls when I am using mobile data? I am happy enough to receive messages, but just not calls.

Thanks guys. I didn't know about the low data option, so I will just enable that when I know I am likely to be using mobile data. Hopefully that will do the trick.
