How to set up a redirect to Xiaomi: the complete guide

Modern Xiaomi and Redmi smartphones have become an integral part of business and personal life, where a missed call can cost an important transaction or a missed opportunity. Call forwarding allows you to automatically redirect incoming calls to another number, voicemail or secretary, providing constant communication even in an unstable reception area or when a line is busy. Owners of devices with a MIUI shell or a new HyperOS often face the need for flexible management of incoming traffic, but standard settings may not be obvious to the beginner.

In this article, we will discuss in detail all available ways to activate call redirection: from the standard phone menu to the use of special devices. USSD-You will learn how unconditional redirection differs from redirection during employment, as well as how to avoid common errors associated with the blocking of service by the operator. Competent setting of these parameters will turn your Xiaomi smartphone into a reliable communication tool that works according to your rules.

Before you start changing system settings, it’s important to understand that this service depends not only on the capabilities of the phone, but also on your mobile carrier’s tariff plan. Some providers may charge extra for incoming roaming calls or for the fact that you use a redirect, so pre-checking the tariff terms is a smart step. We’ll look at the technical aspects of the setup that are universal for most models, including the Mi, Redmi Note and Poco series.

Types of forwarding and their purpose

Xiaomi’s Android and shell redirection features offer multiple scenarios, each of which solves a specific user problem. Understanding the differences between them will allow you to configure the device as efficiently as possible, avoiding situations where the caller hears the beeps but the connection does not occur. The main difference lies in the conditions under which the system decides to redirect the call.

Unconditional forwarding is the most radical option, because it redirects all incoming calls to the specified number immediately, without trying to connect to your device. Your phone may not even ring or vibrate, and the subscriber will hear the horns of the number on which the redirect is configured. This mode is ideal for situations when you are in an area without a network, on an airplane or temporarily using another SIM card, but you want customers to contact your assistant.

There are also conditional redirects that only activate under certain circumstances, like when a line is busy, it saves you when you're talking to another subscriber, and a call from a third person isn't lost, but goes to voicemail or a colleague, and the same thing works for when you don't pick up after a certain time, or when the phone is off or out of range.

• 📞 Unconditional: All calls go to another number instantly.
• ⏳ When you are busy: it works if you are already talking on the phone.
• 🔕 Unanswered: activated if you didn’t pick up the phone in a given time.
• 📡 Unavailable: Works when the phone is off or not on the network.

⚠️ Note: When using unconditional redirects, your phone may stop displaying missed calls in the log, as for the network you technically did not receive a call. Always check the carrier's call log if it is important to track all communication attempts.

The type of email you choose depends on your current needs. In a business environment, you often combine modes: during the day, you can redirect to a secretary, and at night or on weekends you can turn on an unconditional one to voice mail. The MIUI shell allows you to flexibly manage these parameters, hiding complex technical details behind a clear interface.

Setup through the standard phone menu

The most secure and recommended way to manage call forwarding is to use the built-in Phone interface, which does not require memorization of codes and provides visual feedback on the status of each service. The interface may vary slightly depending on the Android version and the MIUI modification, but the logic of actions remains the same for all Xiaomi devices.

To start, open the standard Phone app, which usually has a green tube icon, and in the upper right corner of the screen is a menu represented by three dots or a vertical ellipsis. Clicking on this item will show you a list of options where you need to select Settings or Call Settings. From the list that opens, look for Accounts for Calls or Directions immediately if you have one installed. SIM-map.

If two devices are used in the device SIM-The system will then ask you to choose which SIM to change, and then you'll start the network survey process, which can take a few seconds, and then the phone will send a request to the cellular operator to get the current status of the service. It is important to know that without a network signal (e.g. in flight mode), access to this menu may be restricted or data will not be updated.

Select the type you want, like "Always Redirect," and enter the phone number that will be calling. You can manually type it in or select it from the contact book, which reduces the risk of error. Once you enter the number, click "On" or "OK." The system will send a command to activate the service, and in an instant you will receive a confirmation notification. To turn it off, just go back to the same menu and select "Disable."

• 📱 Open the phone application on the main screen.
• ⚙️ Click the menu (three dots) and select Settings.
• 📶 Go to Accounts for Calls or Redirects.
• 🔢 Enter the target number and confirm the action.

It is worth noting that in some versions of the firmware, the path may look like Settings. → System system → Call forwarding. If you can't find these items, maybe your carrier is restricting control through the menu, and then you'll have to use the menu. USSD-Xiaomi’s standard interface tries to unify these processes, but the network protocols sometimes make adjustments.

Use of the USSD-code-driven

USSD-codes are the universal language of communication between the phone and the mobile operator's hardware, and they work on any device, including push-button phones, and are independent of the operating system version or shell. MIUI. This is a “heavy artillery”, which allows you to configure the redirect even if the smartphone menu is glitched or hidden by the operator.

To activate unconditional forwarding to +79001234567, you need to dial *21*79001234567# and press the call button. The command structure is simple: an asterisk, a service code (21 for unconditional), a target number and a grille. After sending a command, a system message will appear on the screen about a successful activation or an error if the format of the number is incorrect or the service is not available.

21 [phone number]# - Enable unconditional forwarding


#21# - Disable Unconditional Redirection


61 [phone number]# - Enable forwarding if not answered
67[phone number]# - Enable forwarding when employed
62[phone number]# - Enable forwarding when unavailable

To cancel all types of redirects at once and return calls to your number, the universal code ##002# is used. This command resets all redirect settings set earlier, and is a great solution if you are confused in the statuses or the phone has begun to behave strangely. You can check the current status of all services using the command *#21#, which will display information about where and under what conditions your calls go.

⚠️ Attention: When entering USSD-Be careful with the format of the number. Some operators require the number to be entered in an international format (for example, 79xxxxxxxxx), others take local (89xxxxxxxxx). A single-digit error can redirect your calls to someone else’s number.

The use of codes is especially relevant for older Redmi or Poco models, where software can run slower. Commands are processed on the network side, so the response rate depends only on the quality of the signal. If the success message does not appear after entering the code, try restarting the device and repeating the procedure.

Working with engineering menus and hidden settings

For advanced users who don’t find the right options in the standard interface, there is the Xiaomi Engineering Menu, a hidden part of the system designed to test hardware and adjust network parameters at a deep level, access to which requires caution, as changing the wrong parameters can lead to unstable operation 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 without having to press the call button. In the test list, select Phone Information. There's a lot of technical data here, but we're interested in the call section.

Inside the Phone Information menu, scroll down to Call Forwarding, where you’ll see a drop-down list of redirect types (Voice, Data, Fax, etc.) and select Voice for normal voice calls, and then you’ll see the box to enter the number and control buttons: Enable, Disable, and Interrogate.

• 🔧 Enter the code ##4636## in the Call App.
• 📱 Select the item Phone Information.
• 📞 Find the Call Forwarding section and select the Voice type.
• ✅ Enter the number and press Enable to activate.

The engineering menu is useful because it allows you to configure forwarding separately for voice calls, faxes or data, which is not available in the regular menu. However, it is worth remembering that the interface here is minimalistic and without prompts. Any action is instantaneous, so double check the input data before pressing the control buttons.

Table of redirection management codes

For ease of perception and quick access to information, we systematized the main USSD-These codes are universal for most Big Three operators and virtual operators running on their networks, and saving this table or remembering key combinations will help you respond quickly to changing life situations.

The table uses a placeholder number to insert the recipient's phone number. Note that in some cases, after dialing a command, additional confirmation may be required through a pop-up. If the command is entered correctly but the service is not activated, the problem is most likely on the operator's side or in the tariff plan settings.

Solution and troubleshooting

While the procedure is simple, Xiaomi users may encounter a number of problems when setting up a redirect, most often due to the interaction of the device and the operator’s network, and understanding the causes of these failures will quickly resolve the problem without going to the service center.

One of the common problems is the message "Connection error" or "failed to execute the request" when you try activation via the menu. SIM-The card is installed in a slot that does not support voice calls (for example, if the second slot is configured only for the purpose of the card). 4G/LTE without VoLTE, and the network requires 2G/3G In this case, try to move the SIM card to the first slot or temporarily switch network mode in the settings (Settings). → SIM-maps and mobile networks → Network type: 3G/2G customize.

Another common situation is that forwarding is turned on, but the caller hears short beeps or a message of inaccessibility.This may indicate that the number specified for the forwarding is blocked, does not exist, or it also has a redirect that creates a loop.In addition, some rates of “limitless” packets may not include forwarding, and when it is activated, money begins to be written off at minute-by-minute rates, which, if the negative balance, blocks the service.

💡

If the redirect doesn't work, try temporarily disabling the number detector (AON), and on some networks, hiding the number of the sending subscriber conflicts with the rules for redirecting calls.

⚠️ Note: Do not forward to paid service numbers or short service numbers unless you are sure of the pricing, this can lead to a quick expenditure of funds in your or the caller's account.

If none of these methods work, complete a network reset. Go to Settings → Connection & Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This action will remove stored Wi-Fi passwords and Bluetooth settings, but often corrects network login errors that interfere with redirects. After reset, you will need to re-enter passwords from Wi-Fi networks.
