• 📶 Settings SIM-cards – in two-sym Xiaomi, the priority of calls is distributed between slots, and sometimes confused by “automatic choice".

• 🛠️ Failures in the communication module – after updating or resetting the settings, the phone may “forget” the priority device.

If you recently switched from your iPhone to Xiaomi, the problem may be related to the Continuity feature (at Apple, it links calls to iCloud), in which case you need to manually deactivate it on your old iPhone through Settings → Phone → Calls on other devices.

Method 1: Setting Priority SIM-maps (for two-symbol models)

Do the following:

1. Open Settings → Google → Services on this device.
