Since registering my sim with o2 I receive unwanted spam calls.  Did o2 Sell my number?

O2's data base is shared with various 'trusted' partners but they don't actively sell your number

You can block the number that called you, or any number you think may be suspicious.

Thank you, I knew that. How do I stop the calls before they come in and force me to waste time blocking them and how did my number get into the wild?  Someone gave it out without my agreement! O2 is the only person who knows.

@IanIan You can't stop the calls before they come in. If you don't recognise the number, don't answer and let it go to your voicemail. You can change your marketing preferences on your MyO2 page which should at least stop some of the garbage getting through.
