I dont know if any of you know about this. But next week, all UK phones are going to be put on a directory that will allow anyone access to your number, which could leave you open to unsolicited messages and calls.

Theres a BBC article here [link]

If you want to remove your number (Which is highly recommended) go to this site [link]
You will need your mobile phone with you so they can send you a code that should remove you from their directory.

Spread the word on this to help make sure as many people you know are infromed of this to help block their ability to let anyone contact you.

Update - Site isnt working right now for those who would want to remove their number, aparrantly, it should be up and running tomorrow.
