How to Remove Default Calls in Xiaomi Phone: The Complete Guide

Owners of Xiaomi, Redmi and Poco smartphones often face situations where the device behaves unpredictable when an incoming call is made, such as automatic forwarding to another number, instantaneous call reset or no sound signal, which is often confused with a software failure, but in reality it is the result of changed settings or activated operator services.

Understanding how the MIUI or HyperOS call system works is key to solving the problem: the user needs to distinguish between the system settings of the device and the services implemented at the SIM card level, and in this article we will discuss in detail all possible causes and methods for eliminating them.

There are several levels where call automation can be configured, such as "do not disturb," locking unknown numbers, or classic redirects, and diagnosing the current situation accurately will quickly return the phone to its standard behavior.

Diagnostics: Why the phone rings or is silent

Before making configuration changes, it is important to understand the nature of the unwanted actions. Often users accidentally activate functions during a conversation or when using a headset. Android has the ability to remember the last action of the user.

One common reason is to activate In-Car mode or connect to a Bluetooth device that intercepts call management, and it’s also worth checking if flight mode is short-lived, which could have triggered a reset of the operator’s network settings.

⚠️ Note: If the problem is observed only on one SIM card in a dual-symbol device, the reason is likely to be in the tariff plan or services of the operator, and not in the software of the smartphone.

To accurately determine the source of the problem, follow the following steps:

• 📱 Check the status bar for “moon” (do not disturb mode) or “plane” badges».
• 🔌 Disable all external devices and headsets, then restart the gadget.
• 🔄 Transfer the SIM card to another slot to exclude contact with the nest.

If this manipulation has not changed, then we need to move on to a deeper setup of the software interface, and the logic of the call system in Xiaomi is built on priorities: operator settings often take higher priority than phone settings.

Disabling call forwarding through phone settings

The most common scenario where calls go “by default” to another number or voicemail is activated redirection. In Xiaomi smartphones, this function is managed through a standard call menu that broadcasts commands to the operator’s server.

To access the settings, open the Phone app (green handset). In the upper right corner, look for the gear icon or the three menu dots. We're interested in Call Settings or Additional Settings.

In the list that opens, select your SIM card if there are two. Next, search the Redirect section. The system will start a network survey, which can take a few seconds, and you will see a list of conditions:

• 📞 Always redirect.
• ⏳ If it's busy.
• ⏱ If you don't answer.
• 🚫 If not available.

Click on each item and select Disable or Voice Calls -> Disable. If any number is listed, it must be erased. After disabling all items, the status should change to "Redirected Disabled."

It is important to understand that these settings are duplicated. USSD-If you can't turn off the function through the phone menu (it gives you a connection error), use the codes. To completely clean up all types of redirects, dial ##002# and press the call button. This is a universal command for networks. GSM.

Managing Do Not Disturb and Blocking Modes

Sometimes, the default calls mean that the phone just doesn't ring, but silently drops calls or passes them without sound, and MIUI is responsible for this with a comprehensive inbox filtering system, which can be configured to lock all numbers that are not saved in contacts.

Check the Do Not Disturb mode activation. Go to Settings -> Sound and vibration -> Do Not Disturb. Make sure the switch is off. Also check the schedule: it may be switched on automatically at certain times of the day.

Pay special attention to the Blacklist and blocking spam. In the Security app (green shield) or in the call settings, find the Lock option.

• 🚫 Blocking Unknown Numbers.
• 🚫 Block hidden numbers.
• 🚫 Block numbers from other regions.

If you want your phone to ring all the time, regardless of whether there's a number in your notebook, make sure all lock switches are deactivated. Priority contacts are a feature that allows only select subscribers to break through silence mode. Check if it's randomly turned on for a blank list.

Resetting the settings of the “Phone” application and cleaning the cache

Software failures in the system application Google Phone or MIUI Dialer can lead to incorrect behavior. accumulated cache or erroneous data can cause "sticking" functions such as auto-response or automatic reset.

To fix software errors, reset the application settings. Go to Settings -> Applications -> All applications. Find the phone (pipe icon) list. Click on it and select Clear -> Clear cache.

If cleaning the cache didn’t help, you can try Clean Everything (or Reset) and this action will return your call settings to factory settings, but won’t delete your contacts, as they are stored in a separate Contacts app or in the cloud.

In some cases, removing app updates helps. In the same app information menu, click the three dots at the top and select Remove Updates. After that, the system will return to the original version of the call, which often resolves problems after a failed update.

💡

Before resetting your phone app settings, make sure your contacts are synced to your Google account or saved to your phone. SIM-To avoid any theoretical data loss in case of failure.

Use of the USSD-codes for managing operator services

Many of the features that users perceive as phone settings are actually network services. Telecom operators (MTS, Beeline, MegaFon, Tele2, etc.) have their own codes to manage forwarding, waiting for a call, and determining a number.

The most effective way to remove all default settings imposed by the operator or previously activated is to use universal codes. They work on any phone, including Xiaomi, regardless of the firmware version.

Basic codes for management:

• #002# – Cancel all types of redirects (the most important code).
• #43# – Check the status of the service “Waiting call”.
• *43# - Enable call waiting.
• #43# - Disable the waiting call.

Dial the required code in the call app and press the call button. You will receive a pop-up message from the network about the status of the service. If you want to completely clear the profile from any automatic actions with incoming ones, the code ##002# is mandatory.

⚠️ Note: Some forwarding services may be charged when activated or when used.Make sure that by disabling them you are not violating the terms of your plan if the forwarding was part of the enterprise package.

Specific settings for two SIM-map

Xiaomi devices are often used with two SIM cards, and the conflict of settings between them can lead to calls from one card being processed by the rules of the other, or the system does not know which card to use for an outgoing call by default.

Check the default settings for calls. Go to Settings -> SIM-It should have a call point, and if you have to always ask, the phone will tell you which card to call from, which can be perceived as inappropriate behavior.

Also check if there is a redirection between SIM cards inside the same phone, a common mistake: the user sets up a redirect from the Sim-1 to the Sim-2 number, and then forgets about it, resulting in calls to the first number immediately go to the second number, creating confusion.

For the correct operation:

• 📲 Set your preferred card for voice calls.
• 📲 Make sure both cards are active and have a signal.
• 📲 Check if the Symmetry function or redirect inside the device is enabled.

💡

Correct configuration of the two SIM-The cards require that the forwarding settings be separately checked for each card, as they are stored on the network independently of each other.
