What is Roaming Fraud?
Roaming fraud occurs when a subscriber moves from their home public mobile network to a visited public mobile network, and uses services without intending to pay for them. This makes the home network responsible for the subscriber usage and costs incurred, and is one of the most common types of fraud perpetrated today. Fraudsters take advantage of operators’ inefficient data roaming exchanges to produce high-cost international revenue share calls through premium rate numbers, which ultimately rely on operators and subscribers to pay for. As the process to analyze this information is cost, time and labor intensive, usually the local-home network swallows the huge revenue loss, even though it’s not their fault.
