A movie about short messages making people gamble. It's interesting to hear from a friend that there is such a movie. I don't know the name. It seems that someone has received an unknown place.

Yes, I have seen it, too. It is called "deadly mobile phone" or "dangerous mobile phone". It is a computer intelligent program that runs automatically and sends short messages to some people to make them rich. Then they did as the message said, and they all died in the end. Until this hacker (hero) cracked the software.
