Call retention, known as Call Waiting, is a standard feature on mobile networks that prevents important calls from being missed while you’re already talking to another subscriber. However, on Xiaomi Redmi smartphones, this setting sometimes becomes a source of annoyance, especially when an unexpected buzzer interrupts a business conversation or a confidential conversation. Users often face a situation where the option is activated by default by the carrier, and standard switches in the phone menu may not give the desired result due to the unsynchronization of settings.
In the operating system MIUI, The management of telecommunications functions is implemented through the system application “Phone” and hidden engineering codes. Disabling this feature may be required not only for comfort, but also to save traffic if your plan provides for a separate payment for incoming calls.

Configure the function through the MIUI system menu
The most obvious and affordable way to manage call settings is in the standard smartphone interface. Xiaomi Redmi owners can find the necessary switches in the Phone app, which is an integral part of the MIUI shell. To access the settings, you need to open the dialing app and click on the three dots or menu icon in the upper right corner of the screen, then select Settings.
In the list of parameters that opens, you should find the section responsible for accounts SIM-Since modern Redmi smartphones support two SIM cards at the same time, the settings for each of them may vary. SIM-map, «SIM 1" or «SIM 2), and in the additional services menu that appears, find the item “Containment of call” or “Expectation of call.
If the switch is active, just click on it to change the state to "Off." However, often users are faced with the fact that after clicking the boot indicator appears, which can freeze or give a connection error. This means that the Xiaomi smartphone can not send a request to change the parameter to the operator's network in the background.

If the switch in the menu is constantly returned to the "On" position, this indicates a forced activation of the service by the operator.
It is important to note that in some versions of the firmware MIUI The path to settings may be slightly different, sometimes the option is hidden in the sub-menu "Additional settings" inside the partition. SIM-If you don’t see the switch right away, carefully examine all the available items in your SIM card profile.The lack of a visible option may also indicate that the installed version of the Phone app from Google or Xiaomi has a stripped-down functionality for your region.
Use of the USSD-service-management codes
When the graphical interface fails to cope with the task, come to the rescue. USSD-It's a universal language of communication between your Xiaomi Redmi device and the mobile operator server, and it allows you to bypass any interface bugs. MIUI And send a direct request to the network, and to disable the call retention, you use the standard code that you have received in the network. GSM-networks around the world.
To deactivate the function, open the dialing app and enter the #43# combination, then press the call button. The system message will appear on the screen confirming that the Call Wait service is disabled. If you want to check your current status before changing, use the code *#43#. This action does not require Internet access and works even with a negative balance, if outgoing calls are not blocked completely.

Problems with synchronizing settings on Redmi
Owners of Xiaomi Redmi smartphones often note unstable behavior of call settings after an operating system update.This is due to the fact that new versions of Android and the MIUI shell can change the way you interact with the communication module. After a major firmware update, old configuration files may conflict with new system requirements, which leads to the inability to change the call retention parameter through the standard menu.
Another common reason is the disconnection between the phone’s local settings and the carrier’s profile. A smartphone may “think” that the function is off while the network continues to give a wait signal when an incoming call is made, in which case the visual interface in MIUI will show one state and the phone’s real behavior another, the solution being forced resetting of network settings or re-registration on the network.
Also worth mentioning is the impact of third-party calling apps: If you install an alternative caller from Google Play, it can intercept call functions while ignoring Xiaomi’s system settings. In this case, the retention switch should be done inside the interface of the installed application, not through the phone’s standard menu. Check which application is assigned by default to make calls in the system settings.

Comparison of methods of disabling retention
The choice of how to disable the function depends on the specific situation, your Redmi model and the behavior of the carrier. Below is a table that will help determine the best way to solve the problem in your case. Each method has its advantages and limitations, which should be considered before starting manipulation.

| Personal account of the operator | Medium | Tall. | Yes. |
| Resetting network settings | Tall. | Tall. | No. |
Use of the menu MIUI It is most convenient for quick verification, but, as practice shows, often fails when trying to write a new value to the server. USSD-codes are the “gold standard” for such operations, as they work at the network signaling level and are less susceptible to smartphone software errors.
If none of the software methods help, the problem may be deeper: In rare cases, a complete reset of network settings is required, which will remove stored Wi-Fi passwords and Bluetooth settings, but often restores the correct operation of the Xiaomi communication module.
💡
The most reliable way to guarantee the disconnection of the service is to contact the operator’s personal account or use of the service. USSD-command #43# as this changes the parameter directly on the network.
Management through the application of the operator
Modern mobile operators provide users with powerful tools to manage services through their own applications or personal accounts on the site. This is also true for owners of Xiaomi Redmi, since the setting performed on the server side of the provider is the highest priority. When you log into your operator's application (for example, "My Beeline", "My MTS", "My Megaphone" or "My Tele2"), find the section responsible for communication services or charging.

Operator setting is "hard" and overlaps local activation attempts. If you can not find such an option in the application, you should use the support chat within the application and ask the operator to disable the service "Call Hold».
Resetting network settings as a radical solution
When software failures in MIUI cause Xiaomi’s phone to stop displaying or changing service status correctly, network settings may need to be reset.This procedure returns all mobile, Wi-Fi and Bluetooth settings to factory values, eliminating possible configuration file conflicts. It’s important to understand that this action will not delete your personal data, contacts or apps, but will affect network settings.
To perform the reset, go to the Settings menu, select Connect and Sharing (or Advanced Settings in older versions of MIUI) and find Reset Wi-Fi, cellular networks and Bluetooth. Confirm the action by entering the screen unlock password. After the reboot, Redmi will start searching the network again, and the call retention settings should come to the default state determined by the SIM card.
⚠️ Note: After resetting your network settings, you will need to re-enter passwords from all Wi-Fi networks and re-connect Bluetooth devices (earphones, watches, car audio system.
This method is especially effective if you have recently upgraded your firmware or moved from another smartphone manufacturer to Xiaomi, and the old settings conflict with the new system. If after the reset the problem with the retention of the call persists, most likely, the restriction is set at the level of the tariff plan or subscriber profile with the operator.
