A few days ago, my mobile phone received a short message from a good voice in China saying that my mobile phone won the second prize, and I still need to pay a deposit.

This is the most typical fraud, old-fashioned, usually watch more news! Good Voice of China doesn't have this activity at all. Even if there are activities, have you participated? You gave your personal information to the other party, and now you are threatened to pay. Just tell the other person that you have called the police.
