Fraud continues to pound the U.S. telecom industry with little sign of letting up.

Fraudulent use of networks and theft of services in all sectors of the telecom industry continue to grow between 10 percent and 12 percent annually. Though accurate fraud figures are nearly impossible to pin down, between $4 billion and $22 billion is lost each year, and up to 10 percent of a carrier’s bottom line is lost to simple subscription fraud and other low-tech scams, such as when criminals sign up for service using fake names.
