For people who don't know here's how it works:
An attacker needs your email address and phone number (maybe an address, that's sometimes helpful). They call up the cell company and say that the phone has been damaged/lost and they have a new one. They request a number transfer. Occasionally the cell company worker doesn't care and just does this. With a phone number receiving your SMS they reset your email password. The rest is easy - your email inbox will tell them what other things you've signed up for, and they change all of the passwords.
That's why you shouldn't give your phone number to untrustworthy people. Activision-Blizzard being high on my personal list...
