Xiaomi smartphone owners often face the need to redirect incoming calls to another number, which may be due to the lack of a network in roaming, the discharged main device or the desire to separate work and personal calls.
System system MIUI And the new HyperOS offers a number of ways to control this setting, and you can use the phone's standard settings menu, special settings. USSD-Understanding the differences between these methods will help you choose the most convenient option for your situation.
In this article, we will discuss all the available configuration options in detail, we will look at the nuances of working with two SIM cards, explain the meanings of different forwarding statuses and help solve typical errors that occur when you activate a service from telecom operators.
The main types of redirects on Xiaomi smartphones
Before setting up, it is important to understand the types of call forwarding. Mobile standards have multiple scenarios, each activated separately, and understanding these differences will allow for flexible management of incoming traffic.
Unconditional forwarding is the most radical option, and when it is turned on, all incoming calls are immediately transferred to the specified number, without giving your phone even a chance to ring, the subscriber hears the horns, but they go to the end of the line where you redirected the call.
There are also conditional redirect types that depend on the status of your device:
- 📞 If busy: The call is redirected when you are already talking to someone or manually reset the call with the drop button.
- ⏳ If not, the system will wait a certain amount of time (usually) 15-30 seconds), and if you do not pick up the phone, the caller will be switched to another number.
- 📶 If not available: This mode is activated when the phone is off, out of range, or in flight mode.
It is important to note that carriers can charge these services in different ways: Roaming redirects can cost significantly more than calling on-line redirects. Always check your provider's charging terms to avoid unexpected costs.
Setup through the standard phone menu
The easiest and most reliable way to manage call forwarding is to use the built-in Android interface adapted by the MIUI shell, which does not require memorization of codes and provides visual control over all parameters.
To start setting up, open the Phone app, which is a standard caller. In the upper right corner of the screen, you'll see a three-dot icon or a gear, which is the input to the settings menu. Click on it and find the "Accounts for Sync" or "Call settings" section immediately.
Further, the algorithm of actions depends on the number of installed SIM cards:
- 📱 If the SIM card is one, you will immediately see a list of redirect options.
- 📲 If two SIM cards are used, the system will ask you to choose which one to change the settings for (Sim 1 or Sim 2).
In the menu that opens, you'll see four main items: "Always forward," "If busy," "Unless answered," and "If unavailable." By clicking on each of them, you can enter the phone number that will be going to the phone or turn off the feature.
⚠️ Warning: After changing any setting, the phone takes 5 to 30 seconds to communicate with the operator's server.Do not try to quickly click Cancel or switch mode while the status update process is underway.
Sometimes users are faced with a situation where the sliders are inactive or settings are reset, which may mean that the service is not connected on the operator side, or the system has experienced a temporary network failure.
Use of the USSD-code-driven
For those who prefer speed or can not find the right item on the menu, there are special command lines, Entering these codes in the dialing field allows you to instantly activate or deactivate services without diving deep into the settings.
The codes are universal for most Xiaomi, Redmi and POCO carriers and models. Below is a table of basic commands to help you manage calls:
| Action. | Team code | The result |
|---|---|---|
| Insert unconditional | **21*number# | All calls go to the specified number. |
| Disable unconditional | ##21# | Calls are coming back to the phone. |
| Turn off all kinds | ##002# | Complete reset of all redirections |
| Check status. | *#21# | Displaying the current state |
To use the code, simply dial it as a regular phone number and press the call button. A pop-up notification from the operator will appear on the screen that the service has been activated or deactivated.
Special attention should be paid to the code ##002#. It is a "nuclear" reset option, and if you don't remember what settings you've turned on, or the phone is acting strangely, this command will return everything to the factory redirect parameters.
⚠️ Note: When entering a number in the code **21* do not use pros, brackets or dashes. enter only numbers starting with the country code (for example, 79991234567).
Features of working with two SIM cards
Xiaomi smartphones are famous for their support for two SIM cards, which creates additional nuances when configuring redirects. The user should clearly understand which SIM he changes the settings for so as not to confuse the flow of calls.
In the call settings menu, each type of redirect is duplicated for SIM 1 and SIM 2. If you turn on Always Redirect only for the first SIM, then calls to the second will come in normally, which is convenient for creating complex traffic filtering schemes.
For example, you can set up the following scheme:
- 📞 On the main SIM card, set up a redirect “If not responding” to voice mail or a secretary.
- 📲 On the second SIM card (working) to include “Always forward” to the main number after hours.
However, it is worth remembering the limits: some operators limit the number of simultaneous forwardings or do not allow redirecting calls between the numbers of different operators at no additional cost.
☑️ Checking before setting up
Problems and Solutions: Why Redirection Doesn't Work
Despite the ease of setting, users often encounter errors: the phone can write "Request Error" or "Redirect settings failed to change" This does not always mean that the smartphone is broken.
The most common reason is the operator's services: if there is no money on the account or the Redirect service is not included in the tariff plan, the network will reject your request, and the problem may be in the number format: some networks require you to enter the number in an international format.
To avoid a software failure in MIUI, follow the following steps:
- Reset the device.
- Check if the ban on outgoing calls is worth it.
- Try to move the SIM card to another slot.
If nothing works, it makes sense to reset your network settings, so it won't delete your personal data, but it will return the communication settings to factory values.
⚠️ Warning: Resetting network settings will remove stored Wi-Fi and Bluetooth pairing passwords. Be ready to reconnect to wireless networks.
Additional features and smart scenarios
Xiaomi’s ecosystem allows you to go beyond standard settings, and using the Security app or built-in scripts, you can automate the redirection process.
For example, you can create a scenario where, "If the battery level is below 5%, turn on a backup number redirect," which requires third-party automatizers or deep customization through ADB, but gives you full control.
Also worth mentioning is voicemail: In many modern Xiaomi smartphones with Google Phone, the “If Not Answering” redirect function replaces or complements the answering machine, a more modern approach that allows you to leave a message rather than just re-post the call.
For business users, there are cloud-based PBXs that are managed through applications, in which case settings in the phone itself may not be necessary at all, since the redirection takes place at the server level of the provider.
