I fear that I may have become a victim of such scam. Truth is, I compromised my phone (apparently - okay, yes, not the smartest thing to do, but I did), and started getting random, meaningless text messages sent as e-mails (970-1, 970-2, 950-0). The first of them was "Congratulations! You have just subscribed for to Cosmopolitan Tip of the Day".
I didn't do anything except sending a text message on another (presumably dead) non-short number.
What can happen now (like Premium Messages scam or something) and what should I do? How can I, if someone scam-subscribed me, unsubscribe now?
I keep my balance at 0 at all times (pre-paid unlimited), hope that helps...
