Echelon Conspiracy (2009) on Netflix

Plot summary

Max Peterson travels for his job, installing security systems on computers. An unreleased mobile phone reaches him from an unknown sender, and its messages start to pan out: it tells him to skip a flight, and the plane goes down. Another message names a stock that climbs in value, and the phone then sends him to Prague, where it points him to a slot machine. He takes a hundred thousand euros, and the next instruction has him stake the whole amount on one hand of blackjack, which he wins too. To keep gambling, Max gets help from Yuri, a Russian cab driver, who rigs him an earpiece that reads the texts aloud; a machine pays three million euros, and John Reed and casino security try to detain him.
