How to Set Up Call Redirections to Xiaomi: The Complete Guide

Xiaomi’s modern smartphone has long since ceased to be a mere means of communication, becoming a digital communications control center. However, basic features such as call forwarding remain critical to efficient operation and personal comfort. The ability to automatically forward incoming calls to another number is useful in situations where you are out of range, busy or simply do not want to be disturbed on the main SIM card.

Shell interface MIUI Or HyperOS can hide some system settings, making it hard for the average user to find them. Standard menus are often overloaded with visual elements, and find familiar options. GSM-In this article, we will look at all the ways that you can activate this feature, from built-in menus to using engineering commands.

We’ll look at not only standard scenarios, but also the nuances of working with two SIM cards, which is relevant for most Redmi and Poco models. Understanding voicemail and conditional redirects will help you manage incoming traffic flexibly. Get ready to gain comprehensive knowledge of how to make your phone work exactly the way you want it to.

The main types of redirection and their purpose

Before you start technically configuring, you need to understand exactly what kind of call forwarding scenarios the mobile operator network offers. Redirection is not a single switch, but a set of rules that the phone transmits to the base station. Globally, all kinds are divided into unconditional and conditional, and each type solves specific user tasks.

Unconditional redirection is the most radical option, where the call is redirected instantly, without giving your device even a chance to ring. It's ideal for vacations or appointments when you're completely unavailable on that number. Unlike it, conditional options only work when certain events, such as line employment or no response, occur.

• 📞 All incoming calls go to another number.
• ⏳ If busy: Redirects are activated when you are already talking to someone.
• ⌛ If no response: the call is redirected after a few beeps if you don't pick up the phone.
• 🚫 If not available: it works when the phone is turned off or there is no network signal.

It is important to note that activating some of these features, especially those involving waiting or mail, can be charged by the operator as an outgoing call. In roaming, this can lead to significant costs, so always check the tariff conditions.

⚠️ Note: When you activate a forwarding to other operators' numbers or roaming, additional charges may be charged according to your carrier's tariffs.

Understanding these differences allows you to create complex use cases, such as setting up a voicemail forwarding if you haven't answered, but leaving the option to call you while the line is free, and the flexibility of these settings makes them a powerful tool in the arsenal of any Xiaomi owner.

Configure via the standard call menu

The easiest and safest way to manage calls is to use the built-in interface of the Phone app, which is either a standard Google caller or a proprietary MIUI Dialer app, depending on the region and firmware version, in both cases the algorithm is similar, although the visual design may differ.

To start, open a call app and find a three-dot or gear icon that indicates settings. In the settings menu, look for "Call Accounts" or "Call Settings," which is where the functionality we need is hidden, which is often hidden in the back of the submenu so that the main interface is not overloaded.

Once you enter the call settings section, the system can suggest you select a SIM card if there are two of them on the device. Choose the one you want to set the rules for. Next, you will see a list of options available: Redirect, Additional settings, or Voicemail. When you click on the desired item, the phone will send a request to the network to obtain current status.

In the window that opens, you can select the type of redirect (always if busy, etc.) and enter the target phone number. After entering the number, click "Enable" or "Install." The device will display a notification that the setting has been successfully applied. If there is an error, check the correct number entered and the network is available.

To turn off the function, just go back to the same menu and select "Disable" or "Switch off," the system will confirm the reset, and calls will again begin to flow directly to your device, which is good because it is visually clear and does not require memorizing complex codes.

Use of the USSD-code-driven

For those who prefer speed and accuracy, or in cases where the phone menu is not working properly, there are special options for the user. USSD-These codes are universal and work on any GSM-These commands are entered directly in the dialing field, as a normal call.

The basic principle of codes is to use asterisks, grids and numbers. 21 is usually responsible for unconditional forwarding, 61 is not responding, 67 is busy. To activate the function, you need to dial a command in the format **code*number phone# and press the call button.

**21*79991234567#

This command will redirect all calls to the specified number. To disable the code ##code#, for example, ##21# will remove unconditional forwarding. To check the current status of all settings, you can use the command *#21#, which will display information about where and under what conditions your calls go.

The use of codes is especially convenient when you need to quickly reconfigure the phone without diving deep into the menu. However, you should be careful when entering numbers, since an error in one digit can activate a redirect to someone else's number. SMS-notification or pop-up report of successful operation.

⚠️ Attention: When entering USSD-Check your target number carefully, and a single-digit error can cause your personal calls to be redirected to an outsider.

Features of settings on two-symbol models

Xiaomi device owners often use two SIM cards at once, which adds a layer of complexity to call management. Android and the MIUI shell allow you to configure redirects independently for each SIM card, but the interface can confuse the inexperienced user. The main rule is always to explicitly specify which card the settings are applied for.

In the call settings menu, you'll see the separation between "SIM 1" and "SIM 2." All redirect installation steps need to be repeated twice if you want to set both numbers the same. Often users set up one card, forget about the second one, and then wonder why calls keep coming to the second number.

In the case of USSD-In two-symbol models, the phone can automatically apply the setting to the main SIM card installed by default for calls. To avoid confusion, before entering the code, it is better to temporarily switch the priority of calls in the network settings or use the settings menu, where the choice of the card is obvious.

Also, when you activate a redirect on one of the SIM cards, the second one continues to work normally, which allows you to create a flexible system: for example, on a working SIM card, you can turn on a redirect to the secretary after 18:00, and leave your personal one unchanged.

Voicemail as an Alternative to Redirection

Often users look for a way to skip a call so they can return to it later, and confuse a forwarding with voice mail. While technically voice mail is also a type of forwarding (usually to an operator's service number), functionally, they are different things. Voice mail allows a caller to leave a message that you will listen to later.

On Xiaomi smartphones, voicemail settings are often integrated into the same menu as forwarding. In the call settings section, you can find Voicemail. By clicking on it, you can choose the operator's service or set up your own number. Unlike simple forwarding, integration with visual voice mail is important here, if it's supported by the app.

Voice mail is preferable if you want to keep a history of missed calls with the caller's comments, but forwarding simply passes the call on, and you may not even know that someone called you unless you keep a record of the number coming from the redirected number. Voice mail is a more ethical and informative option for business communication than blind redirection.

💡

Set up voicemail greetings in advance. The standard "subscriber unavailable" sounds unprofessional. Write down a short message indicating when you should call back.

Activation of voice mail may require confirmation via a call to a special short number. Follow the autoresponder's instructions to record greetings and set a password. After that, configure a "If no response" or "If unavailable" forwarding to the voicemail number specified in the SIM card.

Resolving and solving problems

Despite the ease of setting up, Xiaomi and Redmi users can experience errors when activating redirects. The most common problem is the message “Request error” or “Redirect settings failed to change”, which is often due not to the phone itself, but to the operator’s network response or temporary failures in the registration of the SIM card.

If standard methods don’t work, try rebooting your device, this will update your network registration and may resolve temporary conflicts, and make sure that the redirect service is not blocked by your carrier – some tariff plans may limit this feature or require it to be activated in advance through your personal account.

In rare cases, the problem is application conflict: Third-party callers or spam blockers can intercept call management, try temporarily disabling such applications or resetting the phone application settings in the Apps -> All Apps section, which will return standard system behavior.

If nothing works, call your carrier for support. There may be an old setup on the network side that conflicts with a new attempt. The operator can reset all redirect services remotely, after which you can reconfigure them without errors.

⚠️ Warning: Resetting your network or phone application won’t delete your contacts, but it can reset your call history and other personalized call settings.
