Redirecting calls to Xiaomi: how to set up and avoid errors

Call forwarding on Xiaomi smartphones is a useful feature that allows you to automatically redirect incoming calls to another number if your phone is unavailable, busy or not answering. Somewhere the option is hidden in the deep menu, somewhere you need to activate through the USSD-codes, and in some cases, the mobile operator blocks the function. In this article, we will discuss all ways to enable forwarding on Redmi devices, POCO and Mi, including models on MIUI 14/15 HyperOS and also consider common errors and their solutions.

It’s important to understand that redirects work at the SIM card level, not the phone level, which means that the settings apply regardless of the device — even if you insert the SIM into another smartphone, the redirect rules will remain. However, Xiaomi’s interface provides handy tools to manage this feature without having to remember. USSD-Next, you will learn how to configure forwarding through standard settings, secret codes and third-party applications, and what to do if the option is inactive.

What is Call Redirection and Why You Need It

A call forwarding service is a mobile phone service that automatically redirects incoming calls to a given number in three main scenarios:

• 📵 If the phone is off or out of coverage, calls will be forwarded to a backup number.
• 📞 If the line is busy, for example, when you're talking on another call.
• ⏱️ If you do not respond within a given time (usually 15-30 seconds).
• 🔄 Unconditional redirection – all calls are redirected immediately, without trying to reach your number.

The function is useful in several cases:

• 🔋 You often discharge your phone and want to keep important calls off.
• 🏢 You use a fixed number at work, but you want to take calls to your mobile phone.
• 🌍 Traveling abroad and want to save on roaming by redirecting calls to your local simka.
• 📱 Use two phones and want to centralize incoming calls.

However, there are downsides to forwarding: First, many operators charge for forwarded calls (especially to other networks’ numbers); second, if you are unconditionally forwarded, you will not be able to receive calls on your primary number; and third, some banks and services block access when a forwarding is detected (for example, to confirm payments on a call).

How to enable redirects through Xiaomi settings

The easiest way to set up a call redirection is through the phone's standard menu. The interface may vary slightly depending on the version of MIUI or HyperOS, but the overall algorithm is the same.

1. Open the phone application (pipe icon).
2. Press three points (⋮) in the upper right corner and select Settings.
3. Go to Calls → Call forwarding (or Additional settings → Redirect in older versions).
4. Select the SIM card you want to set up the redirect for (if you have a Dual SIM).
5. Specify the type of redirect: Always redirect - unconditional redirect; If not answer - after a timeout; If not available - when the phone is turned off; If busy - during a conversation.

Enter the number to which the calls will be redirected in the format +79XXXXXXXXX (or 89XXXXXXXXXXX for Russian operators).

Click Enable or OK to save.

Check the SIM card balance (some operators block the function when the balance is negative)

Make sure the forwarding number supports incoming calls

Record the current settings (in case of reset)

Turn off "Do Not Disturb" or "On the Plane" modes

If the call forwarding option is inactive (grey), it may mean:

• 🚫 Your operator does not support the service (for example, some virtual operators such as the Tele2 Or Yota can limit the function).
• 🔒 SIM card installed PIN-code - unlock it.
• 📵 Phone is in mode In the plane or the mobile network is disabled.
• 💳 There is not enough money in the account to activate the service.

💡

If the menu does not have the “Redirect” option, try updating the Phone app via Google Play or clearing its cache in the settings (Settings → Apps → Phone → Memory → Clear the cache).

Activation of forwarding through USSD-code

If the settings in the phone menu are not available, you can turn on the redirect using USSD-This method works on all Xiaomi devices, regardless of the firmware version. Below is a list of codes for the main scenarios:

Examples of use:

• To enable unconditional forwarding to +79123456789, dial *21*79123456789# and press the call button.
• To disable redirects when unavailable, dial ##62#.
• To check if the redirect is active, use *#002#.

Important: some operators (for example, MTS or Beeline) may require confirmation of activation of the service through the SMS supplementary USSD-If nothing happens after entering the code, contact operator support.

⚠️ Attention: When in use USSD-The number for forwarding is indicated without "+" And without spaces, for example, for a room. +7 (912) 345-67-89 need to be introduced 79123456789.

Why Redirects Don’t Work: Typical Problems and Solutions

If you set up a redirect correctly but the calls are not redirected, the reasons may be as follows:

• 📶 Poor network coverage – the operator cannot process the forwarding request. Try rebooting the phone or switching to another network (2G/3G/4G).
• 💰 Not enough funds - some operators block the service with zero balance#.
• 🔄 Conflict with other services – for example, if you have an active service “AntiAon” (MTS) or “Inbox Prohibition” (Beeline), the redirect may not work.
• 📱 Number error – check if you have correctly specified the number to be redirected (especially the country code).
• 🔒 Operator restrictions - some tariffs (for example, "for laptop" from the Tele2) They don't support forwarding.

If the problem persists, follow the following steps:

1. Turn off all types of redirects with the code ##002#.
2. Reboot the phone.
3. Enable redirects again via the menu or USSD.
4. If it does not help, contact the operator’s support and request a check on the service on your number.

Redirect to Xiaomi with two SIM cards (Dual SIM)

If your Xiaomi smartphone supports two SIM cards, the redirect setting has features: First, the redirect is set up separately for each SIM. Second, if you use both SIMs at the same time (for example, one for calls, the other for the Internet), the redirect can conflict with other services.

How to set up a redirect for each SIM card:

1. Open the Settings. → SIM-maps and mobile networks.
2. Select the SIM card you want to set up the redirect for.
3. Go to Call Redirection (or use it) USSD-codes, specifying before the SIM number, for example, *21*79123456789,,1#, where,,1 — sim card number).
4. Activate the desired type of redirect.

Pay attention to the following nuances:

• 🔄 If both SIM cards are redirected to the same number, redirect loops may occur (the call will endlessly "jump" between the SIMs).
• 📵 If the main SIM card (from which the redirect is being sent) is disabled, the redirect will not work.
• 💳 Some operators only allow forwarding to numbers on the same network, for example, MTS may block redirection to Beeline number.

⚠️ Note: On Xiaomi devices with HyperOS (e.g. Xiaomi 14 or Redmi Note 13 Pro)+) The redirect menu may be located elsewhere: Settings → Connections → Call forwarding. If you don't find an option, use it. USSD-code.

How to disable redirects to Xiaomi

To deactivate redirects, you can use one of three methods:

1. Using the phone menu: Open Phone → Settings → Call forwarding. Choose active forwarding type. Click Disable.
2. Through USSD-Codes: To cancel all redirects: ##002#. To cancel a specific type (e.g., "if you don't answer"): #61#.
3. Through operator: Call your carrier's support and ask them to disable forwarding. This is true if you can't do it yourself.

After disabling, it is recommended to check the redirect status with the code *#002#. If the operator's response indicates Forwarding disabled (or a similar message in Russian), then the service has been successfully deactivated.

💡

If you are selling or transferring your Xiaomi smartphone to another person, be sure to turn off the redirect so that new SIM card holders don’t receive your calls.

Third-party applications for forwarding management

If Xiaomi’s standard tools don’t work, you can use third-party apps to flexibly configure redirects. Here are some proven options:

Advantages of third-party applications:

• 🔧 More flexible settings (e.g., redirect only to certain contacts).
• 📊 Redirect history and call statistics.
• 🔔 Notifications of forwarded calls.

However, there are risks:

• 🛡️ Some apps require access to calls and contacts, which may not be secure.
• 💰 Some of the functions may be paid.
• 🔄 Applications may conflict with standard settings MIUI.

Before installing, check the reviews and rating of the app in Google Play. If after installation the redirect stopped working, delete the program and reset the phone to factory settings (Settings → About Phone → Settings Reset).
