Not OP, but AFAIK that doesn't work for Whatsapp or other in-app calls, and since my family lives in another continent if there's an emergency they'll call via WhatsApp.
An argument could be made that because I live far away I don't need to be informed of emergencies right away, but there are cases in which I would like that, even if just to buy a same day ticket to go back as soon as possible.
