C&P'd from a recent e-mail..
There was an item on the BBC radio about a telephone scam...
You get a call on your mobile - it only rings once or twice then cuts off - your mobile will show a missed call - even if you do try to answer immediately you do not get connected to anyone - if you try to ring back, thinking it's a missed call, you only get a ringing tone and no-one answers, the number of the caller will be something like 07016 and you think it's a mobile, infact 070 is what they call "follow me" numbers - it's a number which you can ring and the person can redirect the call to their home, their mobile, their office, or wherever they are - the number in itself should not cost you any extra to ring and there is nothing in itself suspicious about an 070 number.
however, the scam is that, if you listen carefully when you try to ring a scam call, it rings once or twice, then there's a gap of silence, followed by more ringing - what they think the scammers are doing is letting the call be answered by an answering machine and instead of you getting a message they play back to you the sound of a telephone ringing so you don't realise it has been answered
the authorities are not sure how the scammers are making money out of this, but the reality is that people are being charged for calls they don't realise they are making - because all they've heard is a ringing tone they don't realise they've been connected - when they get their mobile phone bills they are very surprised to see they've been charged
so the advice is, if you get a missed call and it's an 070 number, don't ring back unless you're absolutely sure you know the person who's rung you..
Just be careful out there :-/ :-/ :-/
