Abstract
A telecommunications system is configured to prevent Subscriber Identity Module (SIM) swap scams. The system includes multiple network nodes and a database. When a SIM change occurs for a given phone number, a messaging process is triggered between the network nodes that temporarily sets a flag in the database associated with that phone number. While the flag is set in the database, messages for the phone number are not delivered in a normal manner. Instead, the messages are analyzed by the network for the presence of secure information, such as one-time passwords (OTPs). If a message is determined to be secure by the network, then delivery of the message is blocked, thereby preventing a fraudster from performing SIM swap fraud using the message.
