This feature is especially critical for users who use one SIM for work and another for personal calls. For example, if you set a priority on a working SIM, but your smartphone suddenly starts calling from a personal one because of a parallel call, this can lead to awkward situations.

Method 1: Disconnecting through the main settings SIM-map

The easiest method is to use the standard MIUI settings menu, which is suitable for most Xiaomi Redmi models, including the Redmi 9/10/11/12, Note series and even older devices on MIUI 11.

Method 2: Use of an engineering menu (for advanced users)

If the standard settings do not disable parallel calls, you can use the Engineering Mode, which works on 90% of Xiaomi Redmi models, but requires caution - incorrect actions can disrupt the mobile network.

Steps to enter the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##4636## (for MIUI 13/14) or #36446337## (for older versions).
