Operators might have shit load of data flowing through their network but they need the ways to structure that so its a big investment, on the other hand, mobile aggregators are freaking obsessed about mining every bit of info they have (i know this because I was hired to squeeze that juice) so they could push you more crap. Even if you don't participate in SMS games (quizzes, tv voting, etc) there services like emergency top up (for prepaid sims) that you probably used at least once or twice. Those are usually also provided by mobile aggregators itself or through MA partners, and they do know on which channel request came, what VAS app is that, how often you do this and etc. Ideally they can cross check your phone number on all of their services and content provider services to get plenty info to know who you are and what you will buy next.
