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

When you can't answer an important call, every smartphone owner has a meeting, a poor network coverage, or a dead battery, and it's at that point that the call forwarding function becomes critical, allowing incoming calls to be redirected to another number.

Owners of Xiaomi, Redmi and POCO Often face the nuances of the interface MIUI And the new HyperOS, where standard customization paths might not be obvious, unlike pure Android, it has its own menu layout and workflows. USSD-team.

This guide will help you quickly activate call forwarding, set up standby timers, and avoid common configuration errors. We will look at both standard system tools and alternative management methods through operator codes.

Principle of operation and types of redirection

The redirect function works at the carrier level, not just your phone. When you set up this option, the command is sent to the network, which redirects the incoming signal to the number you specified, which means that the feature will work even if your Xiaomi is off or out of range.

There are several basic types of redirects, each of which solves a specific problem, and understanding the difference between them will allow you to flexibly manage your availability, and you can redirect all calls without exception, or only those that come in in a particular setting.

• 📞 Unconditional redirect – all incoming calls go to another number at once, your phone doesn’t even ring.
• ⏳ Timer forwarding – the call is redirected if you haven’t responded within a certain time (usually 15, 30 or 60 seconds).
• 🚫 Redirection during employment – if you are already talking on another line, a new call will go to the specified number.
• 📶 Redirection when unavailable – triggered when the phone is off or out of network coverage.

It is important to note that some types of redirects, such as those for busy periods, may require a call-waiting service, which is often customized on Xiaomi smartphones in the same menu but requires confirmation from the operator.

⚠️ Note: When using forwarding to other operators' numbers or roaming, additional funds may be charged from your account per outgoing minute of connection.

The most flexible setup is conditional forwarding, which allows you to stay connected: if you're busy talking or in a bad signal area, the subscriber will still be able to contact you via an alternative channel. SIM-map.

Setup through the Xiaomi system menu

The easiest and safest way to set up a redirect is to use the built-in shell tools MIUI or HyperOS. The interface may vary slightly depending on the Android version, but the logic remains the same. You do not need to download third-party apps.

First, you have to open the standard Phone app, which usually has a green phone icon, and that's where the basic call settings are, don't confuse it with contacts or call history, we need the settings menu.

1. Open the phone app.
2. Click on the three dots in the top right corner of the screen (or the “More” button).
3. In the drop-down menu, select Settings.
4. Find the Accounts for Calls or Calls section via SIM.
5. Choose the right one. SIM-card if you have two of them.
6. Click on Call forwarding.

Once you select a point, the system will try to download the current settings from the operator's network, which can take a few seconds. If the download is successful, you will see four points corresponding to the types of redirects mentioned above.

In the window that opens, enter the phone number to which the calls will be received. Make sure that the number is entered correctly, preferably in an international format (for example, +7999...). After entering, click "Enable" or "OK". The system will confirm the activation of the service with a message from the operator.

If you want to turn off the feature, just go back to the same menu and hit the Disconnect button. Status changes instantly. This is convenient to do temporarily, like when you step out of the bad reception zone and go back to the city.

Use of the USSD-code-in

Sometimes the system menu of the smartphone can not correctly display the settings due to a malfunction in the work SIM-The maps or the operator's features, in such cases, come to the rescue. USSD-This is a universal method that works on any phone, including the old Xiaomi models.

Codes are combinations of numbers and symbols that are sent directly to the operator's network, and the answer comes in the form of a text message or a pop-up, and it's a quick way to check the status of a service without digging deep into the menu.

To activate the redirect to +79001234567, you need to dial **21*+79001234567# and press the call button. You will receive a notification of successful activation. To cancel, dial ##21#. These codes work instantly.

Using codes is especially important if you are roaming and the phone’s menu interface is unstable. USSD-requests have a higher priority and are processed directly by network equipment, bypassing software add-ons MIUI.

Managing two SIM-map

Xiaomi smartphones are famous for excellent support for two SIM-But setting up a forwarding in this case requires careful attention, and you have to manage the profiles for each card separately, because these are two different lines of communication.

In the call settings menu, you will always see the separation between the cards: "SIM 1" and "SIM 2"; the settings applied to the first card do not affect the second card, which allows you to create a complex logic: for example, call from the work number to redirect to the secretary, and from the personal to the home phone only when the state is turned off.

When adjusting through USSD-It is also important to remember which slot is active for voice calling at the moment, although the codes are usually applied to the card from which the request is coming.

• 📱 Check the balance on both. SIM-maps, as forwarding is often charged as an outgoing call.
• 🔄 Make sure that both cards have data or voice roaming enabled if you are overseas.
• 🔔 Set up different sound signals for SIM-1 and SIM-2, To understand which line is being forwarded to if you are in the access area.

Owners of HyperOS devices should pay attention to the new management interface SIM-There's a smart forwarding feature that can automatically suggest that you redirect a call if you're the primary one. SIM-The card is busy, but this feature requires permission to access contacts.

⚠️ Note: Do not set up a forwarding with one of your own. SIM-card SIM-This can lead to a line blocking by the operator's security service due to suspected fraudulent activity.

If you change often SIM-You can use some cards or adapters, and you can save the redirect settings on the operator's network, not on the phone, so after you reposition the cards, you'll probably have to recheck the redirect numbers.

Problems with redirection and their solution

Despite the simplicity of the feature, Xiaomi users sometimes encounter errors, most often not in the phone, but in network settings or locks on the part of the operator, understanding the reasons helps to quickly find a solution.

One common error is to say “Redirect settings failed to change” or “Request not executed.” This may mean that the service is not connected on the tariff.Some budget plans require a separate activation of the “Redirection” function.

Also, the problem can be caused by a ban on outgoing calls, because redirects are technically an outgoing connection from the network to a new number, having outgoing locks can interfere with the function, and check if you have a limit on outgoing operator settings.

Another reason is application conflict. Third-party callers or number detectors can intercept call management. Try temporarily disabling such applications or resetting the Phone app settings through the Apps menu → Application Management → Phone → Memory → Clear.

If nothing works, reset your network settings. This won't delete your personal data, but will return your Bluetooth, Wi-Fi and mobile network settings to factory values. → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth.

💡

Before contacting the operator's technical support, be sure to restart the smartphone. In 30% of cases, this solves the problem with registering services on the network after updating the firmware.

Third-party applications for automation

Android is not always enough for complex scenarios, for example, if you want to redirect calls only from certain contacts or at certain times of the day, there are specialized applications from Google Play.

Apps like Call Forwarding or Auto Forward allow you to create flexible rules, so you can set up a call forwarding from your boss to your work number and from everyone else to your voicemail, but they require constant permissions and access to calls.

Using third-party software has its own risks: the application must run in the background constantly, which can increase battery consumption, and you trust a third party to access your phone book and call history, which raises security issues.

For most users, built-in MIUI is enough: it's stable, battery-efficient, system-level, and you only need to use third-party solutions if you want really complex logic that's not available on the standard menu.

⚠️ Warning: When installing redirect applications, carefully read reviews and permissions requested. Avoid programs that require access to redirect applications. SMS location without obvious necessity.

An alternative is virtual PBX services provided by telecom operators, which allow you to set up a “smart” forwarding through your personal account or web interface, setting a schedule and contact lists that you need to skip immediately to your phone.
