# Regulatory guidance to mitigate SIM risks

1. **Regulatory coordination: -** a bilateral Memorandum of Understanding (MOU) related DFS should be in place between the telecommunications regulator and the Central Bank on SIM swaps.

2. **Regulators should encourage Mobile network operators to adopt appropriate controls to mitigate SIM risk and Fraud (see** [**Mobile network operator**](/sim-swap-threats/security-recommendations-to-protect-against-dfs-sim-risks-and-sim-swap-fraud/mobile-network-operator-controls-to-mitigate-sim-risks-and-fraud.md) **controls and** [**DFS operator controls**](/sim-swap-threats/security-recommendations-to-protect-against-dfs-sim-risks-and-sim-swap-fraud/dfs-operators-controls-to-mitigate-sim-risks-and-fraud.md)**).**
