How to enable redirects on Xiaomi Android: The Complete Guide

The modern smartphone, especially Xiaomi, has become a central hub for communication, and managing incoming calls requires flexibility. Situations when you need to redirect a call to another number arise regularly: a drained battery, no signal in roaming or just a desire to disconnect from work issues at the weekend. On the Android operating system with the shell of MIUI or the new HyperOS, this process is quite convenient, but has its hidden nuances, which not all users know.

Call forwarding (or forwarding) is a network service that allows you to automatically send an incoming call to another number or voicemail, and it is important to understand that the setting is not only done on the menu of the device itself, but also fixed on the operator side. That is why even after the extraction SIM-The settings of the cards or smartphone changes may continue to apply if they are not forced to reset. owners of Xiaomi Redmi and Poco should be especially careful, as branded shells often change the location of menu items.

In this article, we will discuss all the available ways to activate the function, from the standard interface to hidden engineering codes, you will learn how to configure conditional redirects (only if busy or unavailable) and unconditional (on all calls), and we will also touch on the topic of security, since improper settings can lead to leakage of information or loss of important calls.

⚠️ Warning: Before activating unconditional redirect, make sure the target number has a voicemail service connected or is ready to receive your calls, otherwise callers may hear short horns or resets.

The main types of call forwarding to Xiaomi

Before you start setting up, you need to be clear about the difference between redirects, because it depends on the logic of how your phone works in different situations. Android offers four basic scenarios, each of which has its own purpose. Wrong type selection can lead you to miss an important call, thinking that it is redirected.

The first is Unconditional Redirection, which activates this mode, and all incoming calls are instantly redirected to the number that you're calling, so you can't even get your phone to ring, which is ideal for a vacation, or when you're in a zone where only one operator is catching and you're going to call another, but it's not recommended to use this mode all the time, because you might not notice that you're in stealth mode for calls.

The other three types are conditional redirects and only work under certain circumstances:

• 📞 If busy: the call will go to another number if you are talking to someone else or manually drop a call.
• ⏳ If there is no answer: The redirect will work if you don't pick up the phone after a certain number of horns (usually). 10-15 seconds).
• 📶 If not available: The most useful mode for travel is when the phone is off, out of coverage or in "In Airplane" mode".

On Xiaomi smartphones, these settings can be scattered across different menu subsections depending on the version. MIUI. Sometimes the interface of the call changes after the system is updated, and the usual points disappear. USSD-A team is a must-have skill for a confident user.

⚠️ Note: If no response has a waiting time limit, if you set a waiting time too short before redirecting in the operator's settings, the call may be reset before you have time to respond.

Configure via the standard phone book menu

The easiest and most obvious way to set up a redirect is to use the built-in interface of the Phone application. In Xiaomi shells, this is the responsibility of a standard Google call or a proprietary MIUI Dialer application (depending on the region and year of release of the device), the algorithm of actions here is as simple as possible for the average user, but hides several layers of nesting.

To start, open the Phone app and find the menu button. MIUI These are the three dots in the top right corner or the three horizontal bars. After clicking, select Settings. Next, you'll need to find a section that can be called Accounts and Sync, Additional Settings, or Redirect. Sometimes you have to choose a specific one first. SIM-card, if there are two in the smartphone.

Once you log in to the redirect menu, the system will send a request to the operator's network. This is not an instantaneous process: the load indicator will appear on the screen. If the network responds slowly, there may be a timeout error, in which case you should try again in 1-2 minutes or go to flight mode and back to update the registration on the network.

Select the type of forwarding you want (e.g., Always or When busy) and enter the phone number to which the calls will go. Be sure to specify the country and operator code if the call is long distance or international. After entering the number, press the activation button. The system will contact the operator's server again to confirm the command.

It is important to note that on two-symbol Xiaomi smartphones, the settings for each SIM-You can set up a redirect only for the work SIM, leaving the personal in the normal mode. It is also worth remembering that incoming redirected calls can be charged by the operator as outgoing calls to the number where the redirect is going, especially if you are roaming.

Use of the USSD-commands

For those who prefer speed and reliability, or in cases where the smartphone menu is not working properly, there are many options. USSD-These are special codes that go directly to the carrier server, and they work on any phone, regardless of the Xiaomi model, the Android version, or the status of the menu.

Basic principle of work USSD-The base number for managing forwarding usually contains a service code (often 21* for unconditional or 61* for occupied), followed by a phone number and a grille symbol, Tele2) These codes may differ, so it is best to use standard codes. GSM or the operator's own command.

Consider the basic universal commands that run on most networks:

• 🔢 Activation of Unconditional Redirection: **21* Phone Number # and Call.
• 🚫 Disable all types of redirects: ##002# and call.
• ❓ Redirect status check: *#21# and call.

Once you type in the command and press the call button, the screen will pop up with a network confirmation window. If the command is entered incorrectly, an SMS will arrive with an error or a notification of the incorrect format, the advantage of this method is that it does not depend on the MIUI interface, which can be overloaded with advertising or unnecessary elements.

Engineering menu and hidden Android settings

For advanced users who want to access their network settings, there is an Android engineering menu, which is logged in via a special code in the dial on Xiaomi smartphones, but be very careful: changing the settings in this menu without understanding their purpose can lead to unstable modem operation or complete loss of communication.

To get into the testing menu, open the dialer and dial ##4636##. If the code works, the Testing menu will open. Select Phone information. Here, scrolling down, you can find sections related to setting up calls, although in modern versions of Android 12/13/14, Google often hides these features for security. In some cases, you can see the redirect status, but you can not change it through the interface.

There is also a CIT menu (#6484##) designed to check Xiaomi hardware, and although it is not designed to set up a redirect, it can check the speaker and microphone, which is important if the redirect was enabled due to sound problems. If the calls are not going through normal mode, checking through CIT will help you understand whether the problem is in hardware or in software.

⚠️ Warning: Never reset your settings in the Factory Test or Reset if you are not sure what you are doing. IMEI Or calibration of the antenna, which requires a visit to the service center.

In older versions MIUI There was an opportunity to ADB (Android Debug Bridge is sending commands to change redirects, but with the release of new versions of Android security, these capabilities were significantly limited. API or USSD.

Features of redirection to two-symbol Xiaomi

Xiaomi smartphone owners often use two SIM-And the redirection control is doubled. MIUI It allows you to flexibly customize the rules for each SIM separately, but the interface can be confusing. SIM-a card that is currently selected as active for voice calls or for which the settings menu is open.

When configured through the phone menu, after selecting the type of redirect, the system will always ask: SIM-If you miss this moment or choose the wrong one, the settings will be written to the wrong number. This is a common mistake when the user thinks that he has set a redirect to the main number, and she turned on the second one, which is in the drawer.

In addition, in MIUI It's a function of "Assistant." SIM-A map that allows you to use a second SIM for the Internet while the first one is busy talking, and forwarding can conflict with these settings. For example, if the first SIM is “Redirect if busy”, and the second SIM at this moment gives the Internet, the call may not be redirected correctly due to the busy data channel, if VoLTE is not configured.

You also have to consider the pricing. SIM-card SIM-card 2, while roaming, operator SIM-Card 1 will assume that you are making an outgoing international call to the number. SIM-2 cards. This can be very expensive.Always check the roaming conditions with the operator before you travel.

Table of redirection codes and statuses

To make it easier to understand the different types of redirects and how to verify them, we have created a summary table that will help you quickly navigate the codes and their purpose without rereading the entire text.

Note that activation codes must substitute the full number of the phone to which the redirect will be sent, and the format of the number must be international, starting with the plus and country code (for example, +79991234567).

💡

Save the disable codes (#002#) in your notes or send it to your messenger. In an emergency situation, when you need to unlock your call, you may not have time to search the code online.

Possible problems and ways to solve them

Despite the simplicity of the procedure, Xiaomi users often encounter errors when configuring redirects. The most common problem is the message "Connection error" or "Failure to fulfill the request", which is often associated not with the phone, but with temporary failures on the operator's side or a ban on the service in the tariff plan.

Another common situation is that redirects are turned on, but calls do not come, which can be caused by the target number being protected from spam or blocking unknown numbers, and the problem can be hidden in the application conflict: third-party calls (for example, from Truecaller or Yandex) can intercept call management and ignore the system redirect settings.

What do you do if nothing helps?

• 🔄 Reboot your smartphone. This will update your online registration and reset the temporary modem errors.
• 📲 Call operator support. The service may be blocked at the subscriber profile level.
• 🗑️ Remove third-party calling apps and use a standard caller MIUI Google.

💡

If the redirect doesn’t work either through menus or codes, the problem is almost certainly on the carrier’s side or in the plan, not in the Xiaomi smartphone itself.
