The second call waiting feature, known as Call Waiting, is a standard service. GSM-The owners of smartphones Xiaomi, Redmi and Poco often face a situation when during a conversation, a persistent horn is heard, signaling an incoming call from another subscriber. While this option is useful for business communication, allowing you to avoid missing important contacts, in everyday life it can cause irritation and distract from the current conversation.
Disabling this feature on devices with a shell MIUI or new HyperOS can be done in several ways, ranging from standard phone settings to the use of special operator codes. The deactivation process does not require root rights or deep technical knowledge, but the menu interface may vary slightly depending on the version of the operating system and model of your gadget. In this article, we will discuss in detail all available methods of managing the waiting service so that you can customize your Android smartphone to your personal preferences.
It is worth noting that this function is managed not only by the software of the phone itself, but also by the settings on the cellular operator side. Call Waiting is a network service, and changes made through the smartphone menu send a corresponding request to the operator’s network, so the response rate and success of the operation can depend on the quality of coverage and the current load on your provider’s network.
Standard method through the phone menu
The easiest and safest way to disable the wait for a second call is to use the built-in call interface, which is universal for most models, including Xiaomi 14, Redmi Note 13 and older versions. You do not need to install third-party applications or enter complex commands, all the necessary switches are open access.
To start, open the standard Phone app, which usually has a green phone icon. In the upper right corner of the screen, you'll see a three-dot icon or a gear that denotes the optional settings menu. Click on it, select Settings or Call Settings, and then the system will suggest a list of available options for managing voice communications.
In the list you need to find the section associated with accounts SIM-If you have two SIM cards installed on your device, the system will prompt you to choose which card you want to change the settings for. SIM-A map (like a Sim 1 or Sim 2) and in the menu that appears, look for “Additional Settings” or “Extended Settings” and that’s where the searched “Waiting for a Call” switch is hidden».
☑️ Pre-switch check
Once you find the "Waiting for a Call" item, you'll see the switch. If it's active (blue or green), click on it to deactivate the function. The system may request an action confirmation or simply send a request to the network. In some cases, the process may take several seconds, during which time the load indicator will be displayed on the screen.
⚠️ Warning: After disabling the function, the second caller trying to call you during your conversation will hear the “busy” signal or will be taken to the answering machine, depending on your operator’s settings.
Use of the USSD-service-management codes
An alternative and often faster way to manage network services is to enter a dedicated network service. USSD-These codes are at the protocol level. GSM It doesn't depend on the firmware version or model of your Xiaomi smartphone, and it's especially useful if the phone's settings menu isn't working properly or the interface is changed by the manufacturer.
To turn off the waiting call, you need to open the dialing app and enter the following character sequence: #43#. After entering the last character, press the call button. The system will automatically send the request to the operator, and after a few seconds you will receive a pop-up notification that the service "Waiting for a call" is disabled. SIM-card from which the call was made (or to the main one, if the phone has one SIM card).
There are also codes for status checks and forced function activation, which can be useful for diagnosing communication problems:
- 📞 *#43# – Check the current status of the call waiting service.
- ✅ *43# – activation of the second call waiting service.
- ❌ #43# – Deactivation of the service (similar to the one described above).
It is important to understand that these codes are standard for GSM-networks and work with all major operators (MTS, Beeline, MegaFon, Tele2, However, in rare cases, a telecom operator may block manual management of services through a USSD, requesting changes to settings through the operator's personal account or application. If the code doesn't work, try using the phone menu or contact support.
💡
If the #43# code doesn’t work, try dialing it without pressing the call button – on some Xiaomi models, the request is sent automatically after entering the last grille symbol.
After successfully completing the command, it is recommended to make a test call to make sure the feature is indeed disabled: Ask someone to call you while you are busy talking to another caller, or use a second phone to check.
Customization through the Xiaomi Engineering Menu
For advanced users who don't find the right options in the standard interface, there is access to a hidden engineering menu, this section is designed to test hardware and configure network settings at a low level. Be careful when changing the settings in this menu, as incorrect actions can affect the stability of the communication module.
To enter the engineering menu, open the Phone app and dial ##4636##. If the code is entered correctly, the menu will open automatically, you do not need to press the call button. In the list that opens, select Phone Information. Many technical parameters are displayed here, including IMEI, network type and signals.
In the list of parameters, find the item associated with waiting for a call, it can be called "Call Waiting" or have a similar name, next to it will be a switch or button to change status, change the value to "Disabled" or "Off". If there is no such thing, your version may be MIUI hides this option, and then it is better to use USSD-code.
| Parameter | Description | Recommended value |
|---|---|---|
| Call Waiting | Status of waiting service | Disabled (Disabled) |
| Preferred Network Type | Type of preferred network | NR/LTE/GSM (Auto) |
| Radio Power | Activation of the radio module | On (Included) |
| Set Preferred Network Type | Network type installation | Don't change. |
⚠️ Warning: Do not change the "Preferred Network Type" or "Radio Power" settings in the engineering menu if you are not sure what you are doing, which may result in loss of signal or inability to log in.
The engineering menu is a powerful tool, but for the simple task of turning off waiting for a call, it is often redundant. USSD-codes for some reason do not work or are not available on your device.

Management through the application of the operator
Modern mobile operators provide users with advanced management capabilities through their own applications or personal accounts on the site, which is most convenient if you want to not only turn off waiting for a call, but also check if you have any paid add-ons that affect the processing of incoming calls.
Download your carrier’s official app (e.g., My MTS, MegaFon, My Beeline) from Google Play or AppGallery. Once logged in, look for Services, Tariff, or Communication Settings. The options list often includes Waiting for a Call or Second Call, and the switch next to it will allow you to activate or deactivate the function in a couple of taps.
The advantage of this method is that the setting is applied directly in the operator's database, avoiding possible software errors of the smartphone, which ensures that even when changing the device or repositioning the device. SIM-cards to another phone, settings will remain the same.
In addition, operators' applications often allow you to customize the behavior of the line-taking, such as choosing where the second call will be forwarded to voicemail, to another number, or simply to drop off, which gives you more flexibility in controlling incoming communication than simply turning on or off waiting.
Features of working with two SIM-cards
Xiaomi and Redmi smartphone owners often use two SIM-So you can also do this simultaneously, which makes adjustments to the setup process, and the call waiting function is set up independently for each SIM card, which means that if you turn off the service on the first SIM, you don't turn it off on the second SIM.
When you call one of the SIM cards incoming, when you're already talking to the other, the behavior of the system depends on the settings of each of them. If the active SIM is on, you hear a buzzer. If it's off, the call will be reset or redirected. It's important to check the settings for both cards if you want to completely eliminate the possibility of interruption of the conversation.
In some cases, users are faced with a situation where the first conversation is interrupted when calling the second SIM, this may not be due to the waiting settings, but to the network restriction (for example, if both SIMs are in 2G/3G mode and the phone does not support simultaneous voice and data transmission on two frequencies), in such cases, it is recommended to switch one of the SIM cards to Internet Only mode or use the VoLTE function if it is supported by the operator.
- 📱 Check the settings separately for the Sim 1 and Sim 2 in the phone menu.
- 📶 Make sure that both SIM cards are registered on the network with a sufficient signal level.
- 🔄 When changing the priority SIM card for the Internet, call settings may require re-checking.
The correct configuration of two SIM cards avoids conflicts and ensures stable communication. If you notice strange behavior when calling (resets, no horns), start your diagnosis by checking the status of the waiting service on both numbers.
Solving problems and mistakes
Despite the simplicity of the procedure, users may encounter errors when trying to change settings. One common problem is the message "Request error" or "Can't contact the network" when switching the switch in the phone menu, which often indicates temporary signal problems or operator channels overload.
If standard methods don’t work, try the following:
- Turn on and off the “Air Message” mode to reboot the network module.
- Reboot your smartphone completely.
- Extract. SIM-map, wipe the contacts and paste back.
- Try changing the settings while in the zone of confident reception of the signal (not in the basement or elevator).
Also, consider that some corporate tariffs or virtual operators may limit the ability to manage services independently, in which case the only correct solution is to call your operator’s technical support.
⚠️ Note: If you stop receiving missed call notifications from subscribers who called you during a call after the feature is disabled, check your forwarding settings».
In rare cases, the problem may lie in the software failure of the MIUI shell itself. Resetting calls to factory values (not a full reset of the phone, but only the call settings) can help correct the error.
💡
If none of the software methods helped, the problem is almost certainly on the operator’s side – contact technical support for forced shutdown of the service on their equipment.
