How to set up call forwarding to Xiaomi: all ways

Modern communication requires constant availability, and many Xiaomi users experience situations where they need to redirect incoming calls to another number, which may be due to a bad roaming signal, a desire not to disturb colleagues on vacation, or simply changing their SIM card. In the Android operating system, which runs the MIUI shell or HyperOS, this functionality is implemented quite deeply, but access to it can be hidden in different sections of the menu.

Redmi and Poco smartphone owners often find that standard settings may vary depending on the firmware region or update version. Call forwarding is a network service that is activated at the carrier level, but managed through the phone interface. Understanding how this mechanism works in the Xiaomi ecosystem will allow you to flexibly manage incoming traffic without unnecessary costs.

In this article, we will take a look at all the available customization methods, from the standard menu to the use of engineering codes. You will learn how to configure conditional redirection when a line is occupied and unconditional redirect when the phone is off. It is critical to understand that activation of some types of redirects can be charged by the operator as an outgoing call, so it is worthwhile to clarify the terms of your tariff plan in advance. We will help you understand the intricacies of working with the network settings of your device.

Standard Call Settings in MIUI and HyperOS

The easiest and safest way to activate inbox redirection is to use the phone's built-in menu. MIUI interface may vary slightly from version to version, but the logic remains the same. You need to open the Phone app (green handset) and go to the settings, which are usually hidden under the gear icon or three dots in the corner of the screen.

Once you log into the Call Settings menu, you'll see a list of options available for working with SIM cards. If you have two SIM cards installed on your device, the system will prompt you to choose which one you want to change the settings for, and it's important not to confuse the call accounts so as not to block access to an important line.

Inside the SIM card management menu, you need to find the "Redirect" option, and you click on it, you start the synchronization process with the operator's network, the phone will send a request to the server, and in a few seconds the current status of all types of redirects will be displayed, and this method works consistently on all models, including the Xiaomi Mi, Redmi Note and Poco F series.

The settings interface allows you to manage scripts flexibly. You can choose "If busy," "If not responding," "If unavailable" or "Always." Choosing "Always" means that the caller will never hear the beeps on your current number, as the call will be instantly redirected.

Use of the USSD-code-driven

For those who prefer speed and do not want to wander on the menu, there are special options for the user. USSD-They run on any phone, including Redmi's budget phones, and they don't require an Internet connection, and entering those codes in the dialing field is a direct way to communicate with the carrier's equipment.

There are four basic codes that cover 99% of the average user's needs. Knowing them, you can instantly activate or disable redirects even if the phone's menu is getting stuck or not working properly. Below is a table with the basic commands that are relevant to most Big Four operators.

When using codes, it is important to follow the syntax. Instead of the word "number", you need to substitute the digital address of the recipient, starting with the country or operator code. For example, to redirect to a Moscow number, the code will look like *21*79991234567#. After dialing a command and pressing the call button, you will receive an instant confirmation from the network.

💡

Use the ##002# code to quickly cancel all redirects if you forget where you were redirecting your calls, or if your phone is starting to behave strangely in roaming.

Setup through the hidden Android menu

Deep inside the Android operating system, there's a special testing menu that gives you access to advanced radio module features, and on Xiaomi smartphones, you can get there by typing in dialer code ##4636##. This menu is for engineers, but ordinary users can also find useful tools there.

Once you enter the code, the Test screen will open, and you will select Phone Information, and if you scroll down, you will find Voice Call Forwarding, and if you click on this button, you will see a list of all the possible call forwarding scenarios available to your operator.

⚠️ Warning: Be extremely careful in this menu. Changing the settings of the radio module without understanding the consequences can lead to temporary loss of communication or malfunction of the network.

The advantage of this method is that it often provides more detailed information about the redirect status than the standard menu, where you can see the waiting timers (for example, how many seconds the redirect will go in case of no response) and specific error codes if the activation failed.

Managing redirection for two SIM-map

Xiaomi smartphone owners often use two numbers at once, and setting up a redirect requires attention.The MIUI system allows you to independently configure the rules for each SIM card, but the interface can be confusing.When entering call settings, be sure to check which SIM card is selected at the top of the screen.

Often, a user sets up a redirect for the first SIM card, forgetting that the second one remains in standard mode, which can lead to financial losses if the second SIM card receives important calls that you planned to redirect.

Also, it’s worth considering that when activated redirects on one SIM card, the second one can continue to consume battery power in network search if it’s not used for calls. Some users prefer to completely disable the second SIM card in the settings if it’s not needed at the moment to optimize power consumption.

Problems with redirection and their solution

Despite the simplicity of the procedure, Xiaomi users may experience setup errors, often with the message “Connection error” or “Redirect settings failed to change” and this may be due to temporary disruptions in the operator’s network or problems with registering a SIM card on the network.

One common reason is that the service is blocked by the operator, and some tariff plans do not include default redirects, or it can be blocked when the balance is negative, and it is also worth checking whether the Inbound/Outgoing Prohibition service, which conflicts with call redirects, is activated.

If standard methods don’t work, try the following:

• 🔄 Reboot your smartphone to update your online registration.
• 📶 Make sure there is a stable cellular signal (not just Wi-Fi).
• 📞 Call the operator support service to check the status of the service.
• 🔧 Reset network settings in the Settings menu → Connections and sharing → Resetting Wi-Fi, Cellular Networks and Bluetooth.

Security and financial aspects

Using redirects is not only convenient, but also risky, and attackers can use this feature to intercept confirmation codes from banks (SMS-Banking, two-factor authentication, if they can access your phone or carrier account settings, so it's crucial to protect your smartphone with a strong password.

The financial aspect is also not to be ignored: a forwarded call is essentially two calls: the first from the caller to you, the second from your phone to the new caller, the second shoulder (from you to the new number) is charged according to your tariff, and in roaming, it can be very expensive.

⚠️ Note: If you are abroad, incoming forwarded calls may be charged as outgoing international calls. Always check the cost of a minute of talking with your operator before activating the feature on the trip.

To protect against fraud, check your forwarding status regularly with the code *#21#. If you see an unknown number, immediately cancel the forwarding with the code ##002# and change the passwords from important accounts. Digital hygiene is the key to the security of your data and money.

💡

Regularly checking the status of redirects with the code *#21# is the best protection against interception of your calls and SMS by scammers.
