01792211844 Annoying calls to new phone

I recently bought a new phone (Nexus 4) and have not given out the details to anybody, except Apple. Today I received an annoying automated call informing me of money I could possibly be owed (PPI insurance most likely). This was obviously some sort of scam, but how did they get my number? There are 2 companies which I have allowed to know my number intentionally, which are Apple and of course my phone supplier Vodafone.

After looking into who might have my number, which now seems to be anyone, my conclusion if that my phone number has been retrieved from one of the apps I have downloaded recently. These apps can access my phone information and send it back to the company or individual, then they will sell it on. So these free apps from android can take information from your phone and sell it on.

Here is a list of possible suspects

• Lazors
• Flow free
• Real Racing 3
• Logo Quiz

It could be none of these, but somehow someone has got my new phone number and sold it on.
