Key things are that u can opt out and that the service doesn't give ur number away, but attempts to patch the person through to u, to which u can refuse. Each time the service used costs £1.
Doesn't seem that life threatening.
If my phone goes and I don't recognize the number, I don't answer it anyway. Phone usually has headphones plugged into it anywho.
Refuse to have my phone rule my life as I see it do to so many people.
To be fair it's less invasive than the old telephone directory for landlines. There u have the same opt out option (which would take a year) and all ur info is there.
What will be the coop is when the number listings are leaked, as u know they will be.
