Set up call forwarding on Xiaomi Mi 9: all ways and life hacks

Call forwarding to Xiaomi Mi 9 is a useful feature that allows you to redirect incoming calls to another number if your smartphone is unavailable, busy or turned off. Despite its apparent simplicity, many users have difficulty configuring it: the menu is not located, the operator blocks the service, then after the update MIUI In this article, we will discuss all the working ways to activate redirects on the Mi 9, including hidden settings, USSD-commands and solutions for cases where the function is not working.

The Xiaomi Mi 9 (cepheus) feature is that the settings interface may differ depending on the version of MIUI (12, 13 or 14) and firmware (global, Chinese, European).We take these nuances into account and provide universal instructions, and consider how to check if the redirects are active, and what to do if the calls are not redirected.

1. Ways to configure redirects to Xiaomi Mi 9

On Xiaomi Mi 9, there are three main ways to activate redirects: through the phone menu, USSD-Each method has its pros and cons, for example, the settings in the phone menu can get lost after the update. MIUI, USSD-teams require syntax knowledge. Let's look at them in detail.

It is important to understand that redirection is of four types:

• 📞 Always redirects all incoming calls;
• 🔄 When you are busy, it works when you are talking;
• ⏰ If there is no response, activate through 15-30 seconds;
• 📴 If not available – works with the phone turned off or out of coverage.

Most operators (MTS, Beeline, MegaFon) support all four types, but unlimited minute rates can block the service.Before setting up, make sure that redirects are allowed by your tariff.

2. Set up via the phone menu (MIUI 12-14)

The easiest way is to use standard MIUI settings. The interface may vary slightly depending on the firmware version, but the general logic is maintained. Here is a step-by-step instruction:

1. Open the phone application (pipe icon).
2. Click on the three dots in the top right corner and select Settings.
3. Go to Call Redirection (or Additional → Redirection in older versions).
4. Select the type of redirect (e.g. Always).
5. Enter the number to which the calls will be redirected, in the format +79XXXXXXXXX or 89XXXXXXXXX.
6. Press Enable or OK.

If the call forwarding item is not on the menu, it can mean:

• 🔄 Yours. SIM-The card does not support the service (for example, virtual operators such as Tinkoff Mobile or SberMobile).
• 📵 The operator has blocked the settings at the firmware level (often found in Tele2).
• 🔧 The phone has custom firmware (for example, LineageOS), where the function is disabled.

Make sure that SIM-The card is active and catches the network

If there is no menu, try an alternative path: Settings → SIM-maps and mobile networks → [choose SIM] → Call forwarding. MIUI 14 This section may be called Additional settings.

3. USSD-Redirect commands (universal method)

USSD-This is the most reliable way, because it does not depend on the version. MIUI The commands are the same for all operators, but may differ in syntax for different types of redirects. Below is a table with the current codes for Xiaomi Mi 9:

Examples of use:

• 📱 To redirect all calls to the number +79123456789, enter in the dialer: *21*79123456789# and press the call button.
• 🔄 To disable redirects if the phone is busy: ##67#
• ❓ To check the forwarding status when unavailable: *#62#

Important: on Xiaomi Mi 9 with firmware MIUI 14 and newer USSD-commands may not work if the settings are disabled "USSD-Requests. To enable it, go to Settings. → Annexes → Application management → Phone. → Permits → USSD-request.

💡

If, after input, USSD-When you get the error "Service is not supported", try adding the operator prefix *111*21*Number #, for Megaphone — *105*21*Number#.

4. Configure via the operator application

Many operators offer their own service management applications, which is convenient if you don't want to remember. USSD-It seems too complicated to use a command or menu for a phone, and let's look at apps for four popular carriers:

• 📱 MTS: My MTS Application. Redirection is in the Services section → Calls. → Redirection.
• 📱 Beeline: My Beeline App. Path: Services → Calls. → Redirection.
• 📱 MegaFon: MegaFon-Service Application.Services section → Calls. → Settings.
• 📱 Tele2: My Tele2 app. Redirects can be hidden in Settings → Additionally.

The advantage of this method is that applications often offer more flexible settings, such as My MTS, which allows you to set a timeout to redirect “if no response” (by default 20 seconds, but you can increase to 30).

⚠️ Note: Some carrier applications (e.g., MegaFon-Service) may conflict with MIUI Xiaomi Mi 9, causing disruptions SIM-If after setting up the redirect, the network signal is lost, restart the phone or delete the application.

If you prefer not to install additional programs, use the web versions of personal accounts operators. For example, for Beeline it is https://my.beeline.ru, for MTS — https://login.mts.ru.

If you set up a redirect correctly but the calls are not redirected, the problem may be one of the following:

1. Go to Settings. → SIM-maps and mobile networks.
2. Choose. SIM-map for which you need to configure redirection.
3. Turn off the second SIM or prioritize in Call Settings → SIM for calls.

6. Additional settings and life hacks

• ⏱️ Timeout before redirect: Operators set delay by default 15-20 You can change it in seconds before you forward the call. USSD-team: *61*Number**30# Here. 30 — time in seconds. Maximum value — 30 seconds.
• 🔄 Conditional forwarding: Set up different numbers for different conditions, for example, if the phone is busy, for a colleague, if it is not available, for a home number#
• 📵 Voice mail forwarding: If you don't want to miss calls, but you don't want to redirect them to anyone, activate the operator's voicemail: *61*123# (where 123 — Short voicemail number of your operator).

Another useful life hack is the automatic deactivation of redirects on a schedule, which you can use the MacroDroid app (available on Google Play). Create a macro that will send you a message. USSD-#21# command at certain times (e.g. after workday).
