Mobile users warned

Scammers know as much about the technology as the companies that develop it, and combining expertise with insight into human nature delivers a money-making racket. The so-called Wangiri scam that has hit mobile phone users in Ireland is the latest example.
The crook calls numbers from abroad, hanging up quickly, the hope being that the intended victim will see the missed call message and ring back because they’re not aware — until they see their monthly bill — that they’re phoning a machine in Nigeria, Liberia or Kazakhstan.
