This is valid, I have gotten
some of these calls as have my friends, we never answer them but these
criminals have gotten good at faking one of your “contacts” when they call, and
if you answer, they could either try to sell you something, or worse, ask for
personal information since they need it for an emergency, or to qualify you for
a free cruise or something. If I had not
seen this on my own phone, I would not think it is a risk, but, I feel sure
this is a risk.
