This is a secret mobile number on a PAYG SIM card.
Now this new mobile gets a phonecall once a day. CLID says "unknown" and the
odd thing is that it never activates the answerphone and rings for a full
minute before stopping. It never calls at the same time of the day but never
rings at night. It's always silent if I answer the phone.
Any ideas? I got the first phonecall within 12 hours of activating the SIM
and no-one had the telephone number at the time other than me and one other
person (I doubt she has anything to do with it)
lol, surely she'd have put it down as a woman's name and the word "work" in
brackets? I knew a guy who used to do that, his missus would phone every new
male or female contact but she wouldn't mess with his (work) contacts in
case she got him into trouble with his boss, dozy cow.
The number will be known by your phone service provider. There is an
obscure piece of European legislation that I found a couple of years
ago, but I can't remember where. It states that the phone companies
*CAN* provide you with the number where calls are of a nuisance nature -
which would include repeated silent calls.

Ok I'll bite.
I'm not sure what "unknown" means in the context of CLID, but
"withheld" AKA "private" are not really anonymous, they are simply
flagged for the terminating telco not to release the number to the
So what you need is a terminating telco that does not honour the
withheld flag. In practical terms this means VoIP. For example
numbergroup.com lets you ignore the flag and pass the withheld number
Here's a screenshot
Remember, it still works if the call is forwarded, your anonymous
caller does not have to dial your new VoIP number.
There are no doubt some legal obligation on you if you choose to
enable this feature.
Oh and one more warning, Numbergroup allows you to sign up and try
their services on a trial basis for an unspecified time, but they will
try to invoice you for services used. They are not like Sipgate and
others that allow you to freeload if you don't actually make calls.
