Electric Zombies (2006)

Every cell phone user in America is at risk of turning into a zombie in this high-tech horror story. The nightmare begins when a government plot to thwart the country's enemies using top secret transmission technology goes awry. Now, zombie-inducing signals have wafted their way into every cell phone in the nation, and ordinary citizens who answer the calls are transformed into the living dead. Paul Wendell, Jonas Moses and Nicole Ashmore star.
