How to Enable Call Redirects to Xiaomi: The Complete Guide

Mobile connectivity has become an integral part of modern life, and missing an important call can be a major problem. Xiaomi smartphone owners running on the shell of MIUI or the new HyperOS often face the need to redirect an incoming call to another number, which can be due to a bad signal in the office, being in roaming, or simply wanting to keep their personal number confidential.

Redirection allows you to flexibly manage incoming traffic, redirecting it to voicemail, work phone or colleague number. Unlike simple button phones, in modern Xiaomi smartphones, this process can be implemented in several ways, each of which has its own characteristics and limitations.

In this article, we will take a look at all the available activation methods, how to use the standard settings menu, how to use secret operator codes, and what to do if the option is inactive, and understanding these mechanisms will help you stay connected, regardless of the circumstances.

Standard redirect settings in MIUI and HyperOS

The most obvious and secure way to manage calls is to use the built-in operating system interface. Xiaomi shells provide convenient access to these functions through the Phone app. To get started, you need to open a standard caller, which usually has a green or blue icon with a handset.

In the interface that opens, find the three-dot menu or the settings gear at the top of the screen. When you click on it, you'll be taken to the general settings section. Here, you'll find Accounts for Calls or Additional Settings, where the functionality is hidden. The interface may vary slightly depending on the Android version.

⚠️ Note: If you use a two-sim smartphone, the system will prompt you to select a specific one. SIM-Make sure you pick the slot that gets the important calls.

Once you select the SIM card, you will see a list of available forwarding options, the system will request confirmation from the network operator, which may take a few seconds, during which time the waiting indicator will be displayed on the screen, and do not close the settings window until the synchronization process with the network is completed.

• 📞 Always: All incoming calls are instantly redirected to the specified number, your phone will not ring.
• ⏳ If busy: Calling will only go to another number if you're talking to someone else.
• ⏱ If you don’t answer: the redirect will work after a certain number of horns if you didn’t pick up the phone.
• 🚫 Unavailable: The call is redirected when the phone is off or out of range.

Choose the type of forwarding you want, and enter the phone number you're going to receive. After you enter, press the activation button. The system will store the settings in your phone's memory and send the request to the carrier's server.

Use of the USSD-quick-activation

For those who prefer speed and do not like to dig into the menu, there are universal options. USSD-These codes work on any phone, including the budget models of Redmi and Poco, and do not require an Internet connection. They send a request directly to the operator's network, bypassing the complex interfaces of settings.

To use this method, open the dialing app and enter the appropriate character combination. The main code for enabling unconditional redirect (always) is the command 21* number phone#. Instead of the words "phone number phone number", you need to substitute a digital code where the calls will go, for example, 21*79991234567#.

**21* Number # - Enable all call forwarding


#21# - Disable all call forwarding




*#21# - Check the forwarding status

There are also codes for situational forwarding, for example, if you need to redirect calls only when the line is busy, the code 67* number# is used. For cases where the subscriber does not pick up the phone, the command 61* number# is used. These combinations allow you to flexibly manage the flow of incoming without deep immersion in the menu.

• 🔢 Enter the code carefully, without spaces and unnecessary symbols.
• 📡 Make sure that SIM-The card is active and has a network signal.
• ✅ After entering, press the call button to execute the command.

After the successful execution of the command, a pop-up notification will appear on the screen from the operator that the service has been activated. If you make a mistake in the numbers, the system will report the wrong request format, in which case you simply enter the command again, correcting the inaccuracies.

Configure via the Security app and system restrictions

In some versions of MIUI firmware, call settings can be integrated with system optimization utilities. Xiaomi’s Security app often takes control of communication functions to prevent fraud and spam. Sometimes, the call blocker can conflict with redirect settings.

If standard methods don’t work, check the security application settings. Go to Settings → Applications → Security and find the section related to blocking or filtering calls. 4 Make sure there are no hard-line rules that redirect calls to nowhere or block them before the system redirect works.

It is also worth considering that on smartphones with two SIM-These cards can reset when you switch the network mode, for example, when you switch from the network mode. 4G on 3G or Dual mode 4G Priority conflicts may arise, and in such cases it is recommended to explicitly specify in the settings which SIM card is used for data transfer and which is used only for voice communication.

⚠️ Note: After an operating system update, redirect settings can be reset to factory values. Always check the relevance of settings after installing a new version of Android or MIUI.

You can use the engineering menu to diagnose problems with calls, but you should do this with caution. You can log in using code ##4636##. Here you can see the registration status of the network and restart the radio module if necessary, which often solves the problems with sticking out the redirect functions.

Features of redirection when the phone is turned off

One of the most common questions users have about redirects when the device is completely off or in flight mode, and it is important to understand the technical difference between a redirect initiated by a phone and a redirect at the operator network level.

When you set up a redirect via the menu or USSD-This information is stored not only in the memory of the smartphone, but also on the server of your carrier, which is why if your Xiaomi is turned off, discharged or lost, calls will still come to the specified number. The network sees that the subscriber is unavailable and forwards the call according to the last instruction received.

But there's a nuance to Do Not Disturb (DND) mode. Unlike a phone that's turned off, DND mode is a local smartphone function. If the phone is on but it's still, the If Not Responding system redirect may not work, because the phone is technically available to the network, the user has simply not allowed it to call, in which case it's better to use the On-Air profile or turn off the device for guaranteed forwarding.

💡

To ensure that all calls are redirected during the meeting, use Flight mode instead of silent mode, which will cause the network to consider the phone inaccessible and activate the "If unavailable" redirect.

Problems with redirecting to virtual numbers and messengers

Modern users often try to configure forwarding to Internet telephony numbers (VoIP) or applications like Telegram and Viber, and this is an important technical limitation: classic forwarding only works with regular E.164 phone numbers.

You can't directly redirect the usual GSM-Calling to an account in the messenger, because these are different protocols for data transfer. The cellular network does not know how to "call" the application. To implement such a scheme, complex gateways or special services of a virtual PBX are required, which provide a number from which calls are already broadcast to the application.

There may also be problems when trying to redirect to other carriers’ numbers, especially if you’re roaming. Some plans block outbound redirects to “foreign” networks or charge extra for this. Xiaomi owners should be careful when traveling abroad.

• 💰 Check forwarding rates with your operator to avoid unexpected costs.
• 🌍 In roaming, redirecting to a home country number may be paid or prohibited.
• 📱 Direct redirection to messengers is technically impossible without intermediaries.

If you need to combine calls from different sources, consider using a Virtual Number service from an operator or a corporate PBX. This will create a single login number that intelligently distributes calls between your main phone, work phone, and even apps on your tablet.

Diagnostics and disabling of the service

Sooner or later, the need for call forwarding is gone, and it's important to know how to properly disable this feature.If you leave the redirect active to a number that is no longer serviced or off, you risk losing important incoming calls forever.

To completely disable all types of redirects on Xiaomi devices, the easiest way to use a universal reset is to dial the code ##002# in the Phone app and press the call button. This command forcibly cancels all types of redirects, voice mail and line occupation notifications, returning the settings to the factory state.

⚠️ Note: ##002# is a global reset, and once you use it, you will have to reconfigure your voicemail if you use this operator service.

If you prefer to go through the menu, go back to the call settings we talked about at the beginning of this article, where you entered a number before, you should now have a "Disable" button or the ability to erase the number, and when you change the settings, the phone will send a request to the server to update the status.

If the forwarding is not disabled either through the menu or through the codes, and the calls continue to go to someone else's number, the problem may be on the operator's side, in this situation, you need to call the support of your tariff plan and demand a forced reset of the forwarding services on the network side.
