When an important call goes to voicemail or is redirected to another number without your knowledge, it can come at the most inopportune moment. Xiaomi and Redmi smartphone users often face this problem after changing their SIM card or resetting their network settings. Understanding how to manage these features is critical to maintaining control over incoming communications.
The Android system installed on Mi devices allows you to flexibly configure routing incoming calls, but sometimes automatic scripts or operator actions can activate redirects that you do not even know about, which leads to missed business calls or unnecessary costs for communication services.
In this article, we will take a look at all the available methods for deactivating this feature, how to use the hidden engineer codes, where to look for the right switches in the system menu, and what to do if the standard methods do not work.
What is a redirect and why does it turn on itself
Call forwarding is a network service that allows you to redirect an incoming call to another number or to an answering machine. On Xiaomi smartphones with a MIUI shell or HyperOS, this feature is controlled both programmatically and through operator commands. Often users do not realize that they activated it accidentally or it was turned on by default when buying a SIM card.
There are several types of redirects that are important to distinguish when set up: Unconditional redirects transfer all calls at once without even letting the phone ring. When a subscriber is busy or unavailable, it only works under certain conditions, such as when you are talking to another person or are out of network coverage.
β οΈ Note: If a redirect is included with a paid number or voicemail number with a paid subscription, your account may be debited for each minute of waiting or redirecting.
Often, the cause of spontaneous activation is network profile updates or malfunctions in the operator's base stations. In such cases, Redmi receives a new configuration package that can overwrite your personal call settings.
Understanding how this function works helps diagnose the problem more quickly, and if your phone is ringing but it's dropping a call or it's translating it right away, it's likely that Do Not Disturb mode or conditional redirect is activated, and checking your current status is the first step to solving it.
Disabling redirects through the standard settings menu
The easiest and safest way to manage calls is to use the phone's built-in interface. On Xiaomi devices, the path to these settings may vary slightly depending on the shell version, but the logic remains the same. You don't need special rights or a computer connection.
To start, open the standard Phone app, which usually has a green tube icon. In the upper right corner, click on the three-dot icon or gear to get into the settings menu. Find a section called Call Settings or Calls.
In the list that opens, you're interested in "Redirect," and the system can suggest that you select a SIM card if you have two. SIM-The card calls the operator's network and gets the current status of the service.
βοΈ Checking call settings
You'll see a list of four basic options: whenever it's busy, when it's not responding, and when it's not available, next to each item, you'll see the number that's being transferred to, or the word "Voicemail." To turn off the feature, click on the type you want and select "Disable" or "Switch off."
If the standard menu doesn't open or gives an error in the connection to the network, this can mean temporary problems with the signal. In this case, try to switch to flight mode for 10 seconds and back, then try again. Sometimes it helps to reboot the Redmi smartphone itself.
Use of the USSD-quick-reset
For those who prefer speed and reliability, there are special USSD-These commands are sent directly to the carrier's server, bypassing the complex menus of the smartphone. It's a universal method that works on any phone, including the old Mi models and the new flagships.
To disable all redirects at once, use a universal reset code. Open dialer and enter the following combination:
##002#After you type the code, press the call button. In a few seconds, the operator will notify you that the forwarding has been successfully disabled, and this code is guaranteed to remove all call forwarding conditions, including voice mail, returning the settings to the factory state.
There are also codes to manage specific types of redirects if you only need to disable a portion of the features:
- π #004# β Status check of all conditional redirects (busy, no response, unavailable).
- π« ##004# - Disabling all conditional redirects.
- π *#21# β Checking the status of unconditional redirect (always).
- π« #21# β Unconditional redirection.
Code use is especially effective when the phone's interface is getting stuck or not working properly, but it's worth remembering that some operators may block certain commands from being executed or require confirmation via SMS. Carefully read text messages that come after you enter the code.
β οΈ Note: Enter codes carefully, without unnecessary symbols. While most codes are safe, erroneously entering commands to activate paid services can lead to unexpected costs.
Settings of voice mail and communication operator
Often users confuse redirects with activated voicemail. In fact, voicemail is one type of redirect that is activated when you can't respond. On Xiaomi smartphones, the management of this service can be hidden in the depth of settings or depend on the operator.
Owners of dual-symbol devices need to be especially careful. The settings for each SIM card are stored separately. If you turn off the redirect on the first SIM, this does not mean that it will turn off on the second SIM. You need to check the status for each number individually through the menu "Two" SIM-maps and mobile networks".
Some carriers offer advanced call management services through their apps, such as My MegaFon, My MTS, or My Beeline, which often feature more detailed statistics and services that are not displayed in the standard Android menu.
If you use virtual carriers or corporate communications, settings may be controlled by the network administrator, in which case standard disconnection methods may not work and you will need to contact your providerβs support team.
Solving problems if redirects are not turned off
There are times when neither the codes nor the menu settings help. Redmi's phone may give an error called "Unconnected" or "Request Fulfillment Error," which indicates a deeper conflict between the phone's software and network hardware.
One of the common reasons is the incorrect operation of the application "Phone". In modern versions of MIUI, both the standard Google application and the Mi Dialer branded shell can answer for calls. Try to clear the cache and data of this application through the "Applications" menu β "All applications" β "Phone" β "Clean data".
Resetting network settings
Itβs also worth checking if you have third-party call software or spam blocker installed. Aggressive antivirus or number detectors can intercept call management. Try temporarily disabling or uninstalling such applications to check their impact.
In rare cases, the problem lies in the SIM card itself: if it is old-style or has physical damage, contact with the reader can be unstable, leading to errors in registration of services.

Before resetting your network settings, write down passwords from important Wi-Fi networks, as they will have to be re-entered.
If nothing works, reboot the device completely with the power button pressed, and in some cases, it helps to enter Safe Mode, where all third-party applications are disabled, and try to disable redirects from there.
Table of redirection codes and statuses
For convenience, the following is a summary table of the main codes and their purpose, and use it as a cheat sheet when diagnosing communication problems on your Xiaomi device.
| Team code | Action. | Outcome of implementation |
|---|---|---|
| ##002# | Total reset | Disables all types of forwarding |
| *#21# | Verification | Shows the status of unconditional redirection |
| #21# | Shutdown | It's redirecting "Always." |
| ##004# | Resetting conditions | Disables forwarding during employment/unavailability |
You don't have to remember all the codes, but the #002# reset code is worth remembering, and it's an emergency exit from a situation where the phone is behaving strangely, and once it's used, the network will re-register your number, and services should return to standard values.

Use of the USSD-Codes are the most reliable way to manage services, as they operate at the operatorβs network level, regardless of the state of the phoneβs operating system.
