I've read about this scam and it seems interesting to me - is that a realistic thing that might happen if your relative lost a phone? Perhaps it's a market-specific issue, but I have had multiple phones lost/stolen/broken in my life, but I still have the same number I had since my first phone back in the previous millenium, and I somewhat expect that some kid's phone number will stay the same until they die unless they move overseas and get another phone number there (and probably still keep the old one as well). Don't you have number portability across phones and carriers?
