what is the number you dial before phoning someone if you don't want them to know your number?

[Branster]

a sort of 1471 but it doesn't allow the others to find out your number?

So not from your mystery caller then?

i think not. or hope rather.
still it's all very enigmatic now.

mobiles are strange things. once my phone rang and it came up with "mum calling" on the screen (as her number was stored obviously). it wasnt her though, it was some bloke asking for his mate. she was in the car in front of us at the time so i know it wasnt a joke either!!
