How to enable call forwarding on Xiaomi phone

Xiaomi’s modern smartphone is not just a device for entertainment, but a powerful tool for business and everyday communication, where a missed call can cost a major transaction or a personal meeting. Call forwarding allows you to automatically redirect incoming calls to another number if you are busy, out of range or simply do not want to respond right now. The flexibility of MIUI settings gives users full control over where and under what conditions the call will arrive.

Owners of Redmi and Poco devices often face the need to quickly change the call route, but do not know where exactly the right sliders in the interface are hiding. In this article, we will discuss in detail all the ways to activate this feature, from the standard phone menu to using special devices. USSD-And the redirect is configured exclusively at the operator level, so the phone only sends the command to the network.

Understanding how this option works will help you stay connected even if the main SIM card is not available. We will look at the nuances for different versions of the shell, how to cancel redirects and typical errors that can occur in the process. Readiness for any communication situations is a sign of a competent user.

Principal types of forwarding and their purpose

Before we get to the technical steps, we need to clearly understand what kind of redirect scenarios the operator’s network offers. Xiaomi smartphones have four basic types, each of which solves a specific user task, the difference between them lies in the condition under which the call switch occurs.

Unconditional redirects are the most radical option, where calls are redirected immediately, without even giving your phone the ability to make a sound or vibrate. The subscriber trying to reach you will hear the horns, but they will go on the device where you redirected the call, which is ideal for situations where you fully delegate your duties to a colleague or go on vacation.

The other three types are conditional and depend on the state of your device:

• 📞 If busy: the call will go to another number if you are talking to someone else at that moment or manually reject an incoming call.
• ⏳ If no response: The system will redirect the call if you haven't picked up the phone within a certain time (usually). 15-30 seconds).
• 🚫 If not available: the call will switch when the phone is off, is out of network coverage, or is in flight mode.

⚠️ Note: When activating any forwarding, your phone may stop catching the network for a few seconds, as the registration settings in the operator’s network are updated.

Importantly, conditional forwarding is often already activated by default to the operator’s voicemail if the service is connected. Android users only need to change the target number or deactivate the feature if it interferes. Understanding these differences will allow you to customize communication scenarios as efficiently as possible to suit your rhythm of life.

Setup through the standard phone menu

The simplest and most visually understandable way to manage calls is built directly into the Phone app, which is the standard for the MIUI shell. This method does not require memorizing codes and allows you to see the status of all functions in one window. The interface may vary slightly depending on the version of Android, but the logic remains the same.

To start, open the Phone app (green handset) and click on the three dots in the top right corner of the screen. In the drop-down menu, select Settings, then find the Call Accounts section or Call forwarding immediately if the item is in the main menu. The system may choose to SIM-card if two devices are installed in the device.

Once you log in, you'll see four lines that correspond to the types of redirects described above. When you click on any of them, the phone will send a request to the network to get its current status. In a few seconds, a window will open where you can select the action: "Disable", "Enable" or "Voicemail." To activate another number, select "Enable" and enter the target phone number in an international format.

If you want to set up a redirect only when busy, select the appropriate item and enter the number to which the calls will go. MIUI will immediately send a command to the operator and you will receive a notification of successful activation. This is the safest way, since you see the result in real time and can easily return everything back.

⚠️ Note: Make sure you are on your balance sheet. SIM-Cards have funds, as a redirected call is charged as an outgoing call from your number to the forwarding number.

Use of the USSD-code-driven

For those who prefer speed or are in roaming, where the menu can work unstable, there are universal options. USSD-These codes are at the protocol level. GSM It's supported by all carriers, regardless of the phone model, and input instantly activates or deactivates the desired function without having to flip through the menu.

To use this method, open the dial bar and enter one of the following combinations, replacing the "number" with the target phone in an international format (for example, 79990000000). After entering the code, click the call button.

Using ##002# is a “nuclear” option that completely clears all redirect settings on the SIM card, which is useful if you rent a phone or suspect that someone is listening to your calls through a hidden redirect, and once you enter the code, you will receive a confirmation message from the operator.

Managing Redirection through Engineering Menu

In some cases, the standard menu may not display all available options or may not work properly due to firmware errors. Then comes the help of the engineering menu, which provides access to the deep settings of the Xiaomi radio module, logging into it requires caution, as changing unnecessary parameters can disrupt communication.

To enter the engineering menu, most Xiaomi devices with MediaTek or Qualcomm processors use the code ##4636##. Once you enter the combination, a hidden testing menu will open. Select Phone Information. Scroll down to Call Forwarding.

Here you will see a drop-down list with redirect types and fields for entering the number.

• 🔍 Voice: forwarding voice calls.
• 📹 Video: Redirect video calls (if supported by the operator).
• 📦 Data/Fax: Data forwarding (rarely used).

Select the type you want, enter the number, and click Enable, which will change to Enabled, which is especially useful if the MIUI is not a bug and does not show the current status of the service, but remember that the engineering menu is a tool for advanced users.

⚠️ Note: Do not change other settings in the engineering menu, such as the type of preferred network or radio reset, if you do not understand their purpose. 4G/LTE.

💡

The engineering menu is a powerful diagnostic tool, but for a normal redirect setting, it’s best to use the phone’s standard menu or a phone’s standard menu. USSD-codes.

Typical problems and ways to solve them

Despite the simplicity of the procedure, users of Redmi and Poco sometimes encounter errors when activating the feature, most often the problem lies not in the smartphone itself, but in the operator settings or the state of the SIM card, and the diagnosis should begin with checking the most basic things.

If you are receiving a “Connection Error” or “Request not completed” message when you try to enable a redirect, check your account balance. Many operators have a charge for calling forwarding service or require a positive balance even for activation, and also make sure that the service is not blocked by the operator (for example, in corporate rates).

Another common reason is the lack of support for roaming services. If you are abroad, standard commands may not work. In this case, you need to use international codes or contact your operator's support team. Rebooting your phone also helps to update your network registration and reset temporary errors.

💡

If the redirect is not enabled, try to extract SIM-You can erase the contacts with a pin and put them back in, and often the problem is oxidation of the contacts or poor connection.

In rare cases, a conflict may be caused by a third-party call app installed from Google Play.Try temporarily returning Xiaomi's standard number dialer as the default app and checking the feature again.This will help eliminate software conflict.
