The Redmi 9 (M2003J15SC, M2003J15SS, etc.) features a hybrid slot for two nano-SIMs or one SIM+microSD. This means that physically removing one card automatically deactivates the other card if it is installed in the same slot. In addition, some MIUI firmwares have a bug that causes the disabled SIM to continue to consume power in the background. We will show how to avoid this.
