Owning a modern smartphone means always staying connected, but there are times when direct connectivity is undesirable or technically impossible. - Xiaomi Redmi Note 8 Pro, a shell-based device MIUI, It provides users with a wide range of tools to manage incoming calls, allowing them to flexibly forward calls to other numbers or voicemail, and understanding how this function works is critical for those who change frequently. SIM-cards or uses multiple devices simultaneously for work and personal purposes.
The process of activating call redirection can be carried out in two main ways: through the graphical interface of the system or by entering special USSD-Redirection at the software level of the phone only sends the corresponding request to the network of the operator, so the correctness of the work depends on the tariff plan and network settings. Owners of Redmi Note 8 Pro should take into account that the menu interface may differ slightly depending on the version of the installed firmware, but the logic of the work remains the same for the entire ecosystem.
In this article, we will discuss all available methods of setting up, analyze possible causes of failures and provide comprehensive answers to frequently asked questions. Redirect service is almost always charged by the operator as an outgoing call to the number to which the call is redirected, so cost control is mandatory. Deep immersion in technical aspects will allow you to fully control your communications, using the full potential of your gadget.
The main types of call forwarding in MIUI
Before you start to set up a practical setup, you need to clearly understand what scenarios for redirecting calls supports the network and interface Xiaomi. the system distinguishes between several types of conditions under which the call will be redirected, and each of them serves its own specific purposes.
The most common option is unconditional forwarding, which redirects all incoming calls immediately without giving the phone even the ability to start vibration or sound. This mode is ideal for situations where you are in a low coverage area or temporarily using another number. Unlike it, conditional forwarding is activated only under certain circumstances, such as line employment, lack of response within a given time or unavailability of the subscriber.
Owners of the Redmi Note 8 Pro can flexibly combine these settings to create complex phone behavior scenarios, such as setting up a redirect to voice mail if you don't pick up the phone and a secretary if the line is busy.
Special attention should be paid to the “Inaccessible” feature, which is often confused by users with “In-plane” mode. In the context of redirecting, this means that the phone is not registered or off, but if the device is simply in “Do Not Disturb” mode, calls can be blocked locally, but not redirected unless the appropriate integration with the operator’s services is configured.
Setup through the standard phone menu
The most convenient and visually understandable way to manage calls on the Xiaomi Redmi Note 8 Pro is to use a built-in GUI. This method does not require memorizing complex codes and allows you to see the current status of each option in real time. To start, you need to open a standard Phone application, which is usually located in the bottom panel of the screen or in the tool folder.
Once you open the app, you should look at the three dots in the top right corner of the screen that open the drop-down settings menu. This is where the "Call Settings" item is hidden, which is often ignored by users who are used to the general Android settings system. Inside this menu, you should find the "Call Accounts" section or immediately go to "Redirects" if the item is in the root menu directory.
The system will choose SIM-If you have two active cards on the card, this is important because the settings for each card are stored independently of each other, and when you select the card, you will see a list of available redirect types, where you can activate the desired option and enter the target phone number. MIUI usually highlights active functions with a green color or icon.
☑️ Checking before setting up
When you enter a number for forwarding, make sure it is listed in an international format, starting with the country code. For Russia, it is +7, although the system can automatically add it when you select from the contact book. Once you enter the number and confirm the action, the phone will send a request to the network, and after a few seconds you will receive a notification of the successful activation of the service.
Use of the USSD-commands
For experienced users or in cases where the graphical interface is not working properly, there is an alternative method of managing through the USSD-These commands are universal to most people. GSM-They're running on any phone, including the Redmi Note 8 Pro, regardless of the firmware version, and they're typing commands directly into the dialing field, like a regular call, but instead of calling, they're doing a service action.
There is a basic set of commands that allow you to control the basic redirect functions, for example, to activate unconditional redirect using a command like **21*number#, and to disable it - #21#. Knowledge of these codes can save you in a situation where the touch screen malfunctioned or the system is getting stuck, but GSM-module continues to function.
Below is a table with the main commands that are relevant for most Big Four operators in Russia and the CIS. Please note that instead of the number symbol, an asterisk or a grille can be used depending on the syntax of the operator, but the GSM standard involves using a grille to complete the command.
| Action. | USSD-team | Description |
|---|---|---|
| Activation of unconditional | **21*number# | Redirects all calls at once |
| Unconditional shutdown | ##21# | Removes all restrictions on incoming |
| Status check | *#21# | Shows where the calls are going |
| Cancel all redirects | ##002# | Complete reset of all redirection settings |
In the case of USSD-It is important to follow the syntax and not pause during the dial, and if the command is entered correctly, a system message from the operator will appear on the screen confirming the operation. In case of an error, you will receive a notification of an incorrect code or service, which may indicate a blocking of the function by the provider.
What to do if the team is not working?
Specifics of working with two SIM-cards
Xiaomi Redmi Note 8 Pro is equipped with a hybrid slot that allows you to use two SIM-The user should be aware that the settings apply individually to each card, and activate the function on one card. SIM This requires double checks, especially if the numbers belong to different operators.
In the call management menu MIUI The profiles for the first and second cards are clearly separated. When you try to change the settings, the system always asks for clarification: "What card is for?". Ignoring this step can lead to a situation where calls to the work number go to the personal one, and the personal one is left unattended or vice versa. It is recommended to give SIM-cards understandable names in settings, such as "Work" and "Personal" to avoid confusion.
If you redirect calls from one card to another that is roaming or has a packet of minutes exhausted, this can lead to unexpected costs, and the charging in this case is according to the rules of the card operator to which the redirect is being sent, not the one from which the call is made.
There is also a nuance to the number of forwarding, where in some networks, when a redirect call is made, the subscriber can see the number of the original caller, and in others, the number of the intermediate card, which depends on the technical implementation of the service by the operator and is not regulated by the settings of the Redmi Note 8 Pro itself.
Solving common problems and errors
Despite the simplicity of the procedure, users often face situations where redirects are not turned on or are not working correctly.One of the most common reasons is the blocking of the service by the operator. Many providers by default disable the ability to forward calls for security reasons or require its pre-activation through a personal account or call center.
Another common problem is the presence of an installed Voicemail or Auto-responder service, which often conflicts with the forwarding settings for employment or unavailability, as both mechanisms try to intercept an incoming call, in which case priority is usually given to the answering machine, and the call does not reach the number you specified.
⚠️ Warning: If after turning on the forwarding, callers hear short beeps and then reset, check if your number is equipped with a number antideterminer or similar blockers.
It’s also worth checking if Android has Do Not Disturb mode activated with a lock-all setting, in which case the phone may not even try to redirect the call, as it software blocks it at the operating system level before accessing network functions, a mode that often resolves the problem instantly.
💡
Before a long trip, take a screenshot of the redirect settings or write down USSD-This will help you quickly reconnect if you forget which number your calls are going to.
Impact of network and operator settings
It’s important to understand that the Xiaomi Redmi Note 8 Pro is only a tool for transmitting commands, and the real switching takes place on the operator’s equipment. Therefore, parameters such as the waiting time for a response before a redirect (usually from 5 to 30 seconds) are often regulated not by the phone, but by network settings.
And the quality of the redirect depends on the type of network. 4G/LTE Voice calls can be processed via VoLTE technology, which sometimes causes delays in forwarding commands. If you notice calls being disrupted or redirected with a delay, try temporarily switching the network type in Settings. → SIM-maps and mobile networks → Preferred type of network on 3G or 2G check out.
Operators can also impose their own substitute applications for calls that have their own forwarding settings, different from the system. If the standard menu doesn't work, check the settings inside the operator's application if it is installed and has call management rights. However, the classic "call" from Google or MIUI usually takes priority.
⚠️ Note: When roaming, redirects may be operated at special rates. Make sure there is a sufficient margin of funds on the balance sheet, as the roaming number that is redirected to another number can be regarded as two outgoing calls.
