What Mobile Network Operator Fraud Controls for SIM Swap, Account Takeover and CLI Spoofing (GSMA Fraud and Security Group practices; PSD2 Strong Customer Authentication) requires
Mobile Network Operators (MNOs) implement controls against identity-related fraud such as SIM swap, account takeover and Calling Line Identification (CLI) spoofing using risk-based authentication, customer notification and inter-operator information sharing. This guidance is informed by the work of the GSMA Fraud and Security Group (FASG), the mobile industry's working group for fraud and security, and by the strong-customer-authentication requirements of EU PSD2 (Commission Delegated Regulation (EU) 2018/389) where mobile authentication channels support payment authentication. Note: GSMA document FS.33 is the Network Function Virtualisation (NFV) Threats Analysis and does not address SIM swap; there is no GSMA recommendation series numbered NIR.01 to NIR.12 - those identifiers have been removed and the controls below are stated as MNO fraud-control practices grounded in FASG guidance and applicable payment-authentication law.
