I don't see the point. Nobody ever phones me and I can survive without knowing what's happening on Facebook or cycle chat for a few hours.
In an emergency I can make a call on my watch.
Funnily enough, that is exactly what my wife says (except the cycle chat bit)
In the past, the only irritation was that everyone phoned or messaged me, and, I became my wife's social secretary, keeping her diary of hair dressing appointments, lunches with her pals etc etc
Now, with her Alzheimer's progressing, I am under pressure, mainly from the daughters, to get Mrs Boldonlad some kind of tracker, just in case. I did think of an App on her phone, but, she seldom carries her phone, so, I think I am going to have to resort to a tracker secreted in her bag, which she does carry reliably.
