How to set up call forwarding on Xiaomi smartphones: a complete guide

Call forwarding to Xiaomi is a useful function that allows you to redirect incoming calls calls to another number when you are unavailable or out of coverage area. However, setting up this option on smartphones with firmware MIUI has its own characteristics: the menu interface may differ depending on the shell version, phone model (Redmi Note 12, POCO X5, Xiaomi 13T) and even the telecom operator. In this article, we will look at all the current ways to activate forwarding - from standard Android settings to hidden USSD commands and third-party applications.

It is important to understand that forwarding works at the level SIM cards, not the phone. This means that the redirection rules will be preserved even if you insert the card into another device. But there are also pitfalls: some operators (for example Tele2 or Iota) may block the function for certain tariffs or charge additional fees. Before setting up, check the conditions with your provider - this will save time and nerves.

Methods of forwarding calls to Xiaomi: which one to choose?

On smartphones Xiaomi there are three main methods for setting up forwarding:

• 📱 Through the phone settings menu —the simplest option, but the interface may differ depending on the version MIUI (for example, in MIUI 14 the path to the option has changed compared to MIUI 12).
• 📞 USSD commands —a universal method that works even on older models (Redmi 4X, Mi A1). Suitable if the phone menu does not display the forwarding option.
• 🔧 Third-party applications —relevant for users who need advanced settings (for example, forwarding on a schedule or to several numbers).

Which method should you choose? If you need basic forwarding (for example, to another number if unavailable), standard settings are sufficient. For flexible rules (redirection only from certain numbers) you will need USSD codes or applications. And if you often travel and use several SIM cards, pay attention to the nuances of the function. roaming - we'll talk about this below. MIUI. For flexible rules (redirection only from certain numbers) USSD codes or applications will be required. And if you travel frequently and use multiple SIM cards, pay attention to the nuances of how the function works while roaming—we’ll talk about this below.

Setting up forwarding through the MIUI menu (step-by-step guide)

The most reliable way to activate forwarding is to use the built-in settings MIUI. However, the path to the option may differ depending on the firmware version. Below are the current instructions for MIUI 12–14.

To get started, open the application Phone, then:

1. Click on the three dots (⋮) in the upper right corner and select Settings.
2. Go to section Calls → Call forwarding (in some versions the path may look like Settings → Advanced → Forwarding).
3. Select the SIM card for which you want to set up redirection (if you have a dual SIM card Xiaomi).
4. Specify the type of forwarding:
   • 📵 Always — redirects all incoming calls.
   • 🔕 If busy —triggered when you are talking on another number.
   • 📴 If there is no answer —activated after 15–30 seconds of unanswered call.
   • ❌ If unavailable — works when the phone is turned off or out of coverage area.

Enter the number to which calls will be forwarded and confirm the setting.

After activation, a forwarding icon will appear in the status bar (two arrows ⇄). To disable the function, return to the same menu and. press Disable.

⚠️ Attention: On some tariffs MTS i Beeline forwarding may be charged as an outgoing call For example, if you. are redirected to the mobile number of another operator, the fee for the interconnect call will be debited from your account. Check the conditions in the operator’s personal account.

USSD commands for forwarding: universal method

If there is no forwarding option in the menu (relevant for old models MIUI no forwarding option (relevant for older models Xiaomi or custom firmware), you can use USSD codesThis method works on any Android smartphone, including Redmi, POCO and Black Shark. The main thing is to know the correct commands for your operator.

Below are standard USSD codes for activating and deactivating forwarding. Enter them in the application Phone as a regular number and press the call button:

Forwarding type	Activation code	Deactivation code	Status check code
Always	21[number]#	##21#	*#21#
If busy	67[number]#	##67#	*#67#
If there is no answer	61[number]#	##61#	*#61#
If unavailable	62[number]#	##62#	*#62#

Example: to set up forwarding to a number +79123456789 if unavailable, enter:

*62*79123456789#

After After entering the code, you will receive an SMS or notification from the operator about (successful activation). To check which number is indicated for forwarding, use the status check code (for example, *#21#).

⚠️ Attention: On some tariffs MegaFon and Iota USSD commands for forwarding may be blocked. In this case, use the official application of the operator or contact support.

Forwarding through applications: advanced capabilities

Standard settings MIUI and USSD commands allow you to redirect calls only to one number and without flexible conditions. If you need advanced functions - for example, forwarding on a schedule, to several numbers or only from certain contacts - you will need third-party applications. Xiaomi.

Top 3 applications for call forwarding:

• 🔹 Call Forwarding (from Simple Mobile Tools) - a minimalistic application with open source code. Allows you to configure forwarding by time, days of the week, and even geolocation (for example, forward calls only when you are at work).
• 🔹 Truecaller - in addition to identifying spam calls, it has a built-in forwarding function with the ability to select contacts for forwarding. Disadvantage: requires registration and access to contacts.
• 🔹 Tasker —for advanced users. Allows you to create complex scenarios, for example, automatically enable forwarding when connecting to a specific Wi-Fi network or when the battery is below 15%.

Example setup in Call Forwarding:

1. Install the application from Google Play and provide access to calls.
2. Select SIM card (if you Xiaomi with two slots).
3. Click Add Rule and specify the conditions:
   • 🕒 Validity time (for example, from 9:00 to 18:00).
   • 📱 Number for forwarding.
   • 🔄 Type of forwarding (always, if busy, etc.).

Save the rule and activate it.

The advantage of third-party applications is flexibility. For example, in Tasker you can set up forwarding only for calls from unknown numbers, and leave all other calls unchanged. However, remember: such applications require additional permissions, which may affect battery life. section Xiaomi (especially on models with aggressive battery optimization, like POCO F5).

How to check if MIUI is blocking the forwarding application?

Open Settings → Applications → Manage applications, find the application you need and check the section Autostart i Permissions. If the option Autostart is disabled, turn it on - otherwise forwarding may not work after rebooting the phone.

Features of forwarding on dual-SIM Xiaomi

If your Xiaomi supports two SIM cards (for example Redmi Note 12 Pro+ or Xiaomi 13 Lite), it is important to understand how forwarding works with each of them. Here are the key points:

• 🔢 Independent setting: forwarding rules are configured separately for each SIM card. For example, you can redirect calls from the first SIM to the second number, and from the second SIM to the third.
• 📶 Network priority: if one of the SIM cards is roaming, forwarding may not work correctly. Some operators (for example Tele2) block the function in roaming.
• 🔄 Rule conflicts: if forwarding to the same number is enabled on both SIMs, errors may occur. In this case, it is better to use different numbers for forwarding.

To set up forwarding for a specific SIM card:

1. Open Phone → Settings → Call forwarding.
2. At the top of the screen, select the desired SIM (click on its name).
3. Set up forwarding rules as described in the section above.

If you have activated the function Dual 4G mode (available on some models Xiaomi), forwarding can work incorrectly. In this case, it is recommended to disable dual 4G in the network settings or use USSD commands for each SIM separately.

⚠️ Attention: On smartphones Xiaomi s MIUI 13+ When forwarding is activated on one SIM, the second may temporarily lose connection (up to 30 seconds). This is normal behavior - wait until the network is restored.

Problems with forwarding to Xiaomi: causes and solutions

Sometimes call forwarding to Xiaomi does not work or does not work correctly. Let's look at typical problems and ways to solve them.

Problem	Possible cause	Solution
Forwarding is not activated	The operator blocks the function on the tariff	Check the tariff conditions in your personal account or call support
Calls are forwarded, but the subscriber hears "number unavailable"	Incorrect number format (without +7 or 8)	Indicate the number in international format: +7XXXXXXXXXX
Forwarding is disabled after reboot	Resetting network settings or application conflict	Check autostart applications in Settings → Applications
Forwarding does not work in roaming	Operator restrictions	Use a local SIM card or disable roaming services

If forwarding is enabled but calls are not forwarded, follow these steps:

1. Check your balance SIM cards - some operators block the function with a negative balance.
2. Reboot the phone - sometimes failures in the communication module can be resolved by a simple reboot.
3. Reset network settings: Settings → SIM cards and mobile networks → Reset network settings.
4. Update the firmware MIUI —in older versions there were bugs with the work of forwarding.

On smartphones Xiaomi with a processor MediaTek (for example, Redmi 10C or POCO M5) redirection may conflict with the function VoLTE. If after activating redirection the Internet disappears, disable VoLTE in the SIM card settings.

Forwarding and privacy: what you need to know

Call forwarding is a convenient feature, but it has privacy risks. Here's what you should pay attention to:

• 🔍 Call access: If you use third-party forwarding apps, they have access to your call log. Before installation, check permissions and reviews in Google Play.
• 📡 Call Interception: When redirecting to another number, the operator may technically record conversations (this is legal in some countries). Avoid discussing sensitive information on forwarded calls.
• 💳 Additional costs: If you forward calls to an international number, the cost may increase significantly. For example, redirection from a Russian SIM to a number in Uzbekistan can be charged as an international call.

To minimize risks:

• Use forwarding only to trusted numbers.
• For important calls it is better to use conditional forwarding (for example, only if the phone is turned off).
• Regularly check the call log for suspicious forwardings - this may be a sign of hacking SIM cards.

If you travel often, pay attention to geo forwarding. Some apps (for example Google Voice) allow you to set rules based on your location. For example, you can forward calls to a local number only when you are abroad.

FAQ: Frequently asked questions about forwarding to Xiaomi

Is it possible to set up forwarding to several numbers at the same time?

Standard settings MIUI and USSD commands do not support forwarding to several numbers. However, some third-party applications (for example Tasker) allow you to create forwarding chains: first to one number, then to another if the first one is unavailable. An alternative option is to use a cloud PBX (for example, Zadarma or Mango Office), which will distribute incoming calls to several numbers.

Why did the forwarding option disappear after the MIUI update?

In some versions MIUI (for example, MIUI 12.5 Enhanced) the developers Xiaomi moved the forwarding option to another menu. Try the following paths:

• Phone → Settings → Advanced → Forwarding
• Settings → SIM cards and mobile networks → Call forwarding
• Settings → System applications → Phone → Forwarding

If the option is still missing, use USSD commands or third-party applications.

How to disable forwarding if you forgot the code?

If you activated forwarding via USSD command and forgot the number to which calls are forwarded, use the status check code:

• To check all forwarding rules: *#002#
• To disable all types of forwarding: ##002#

After entering the deactivation code, you will receive an SMS from the operator with confirmation. If this does not work, contact your operator's support with a request to reset the forwarding settings.

Is it possible to forward calls to instant messengers (WhatsApp, Telegram)?

There is no direct forwarding from a standard SIM card to instant messengers, but there are workarounds:

1. Use virtual SIM (for example, Google Voice or Skype Number), which can redirect calls to instant messengers.
2. Set conditional forwarding to the number associated with WhatsApp Business (the function is available for business accounts).
3. Install the application IFTTT and create an applet that will send a notification to Telegram when a missed call.

Please note: such schemes may violate the rules of some operators (for example, MTS prohibits the use of SIM cards for automatic sending of messages).

Does forwarding work if the phone is in the "Airplane" mode?

No, in the On an airplane mode the communication module is disabled, so redirection doesn't work. In order for calls to be redirected in this case, you need to:

1. Enable mode On an airplane.
2. Manually activate Wi-Fi (if you need to maintain access to the Internet).
3. Enable option Calling over Wi-Fi in the SIM card settings (not available on all operators).

However, even with active calls over Wi-Fi, forwarding may not work - this depends on the operator's policy. For example, Beeline supports forwarding in On an airplane mode with active Wi-Fi Calling, but Tele2 does not.
