Xiaomi smartphone owners using operator services Tele2, Often encountered with an intrusive interface called SIM-It's a standard app. SIM Toolkit, which is built into the Android operating system and is designed to manage services through text commands. However, in modern conditions, it often becomes a source of irritation, as it can spontaneously open, block working windows or display outdated banner ads from the operator.
Users are particularly concerned when the screen goes out after an incoming call or text and then lights up from the SIM card menu, blocking access to the basic functions of the phone. Deleting this system component with fully standard methods will not work, since it is part of the firmware, but there are several effective ways to hide it, turn off notifications or limit background activity. Below we will discuss in detail all available options for solving this problem.
It is important to understand that interfering with system applications requires care. Although the methods described below are safe for user data, incorrect actions in deep settings can lead to unstable operation of the communication module. SIM Toolkit is only possible through ADB-commands with root or computer permissions, which requires technical training. For most users, the software settings described in the following sections will be sufficient.
Why does the SIM menu appear and can it be removed?
The SIM Toolkit (STK) feature was introduced in the days of button phones to provide access to banking services, balance and news without access to the Internet. On Xiaomi smartphones with a MIUI shell or HyperOS, this application often remains active by default. Tele2 uses this channel for (push) its services, which causes a periodic window on the screen.
Many users are wondering why this menu is even necessary when all services can be configured through the operatorβs personal application. The fact is that STK runs at a lower level than regular applications and has display priority. That is why it can pop up on top of other windows. Complete removal of the system package is possible, but requires the use of special tools such as ADB (Android Debug Bridge).
Technical details of the SIM Toolkit
It is worth noting that disabling the menu will not affect the quality of communication, the ability to make calls or use the mobile Internet. You will only get rid of the visual interface of service management. If in the future you need to activate a specific operator service through a SIM card, you can always temporarily return access to the menu through the application settings.
Disabling notifications and pop-up windows
The easiest and safest way to get rid of annoying bursts of SIM card activity is to prevent the application from displaying notifications. MIUI has a flexible rights management system that allows you to fine-tune the behavior of each system process. You do not need third-party software, just go to the standard settings of the smartphone.
First, you need to find the application itself in the installed program list, and because it's system-based, it can be hidden in shared lists or have a name. SIM-map, SIM Toolkit or just Tele2 (When you find the right item, open the properties.
- π± Go to Settings. β Annexes β All applications.
- π Find it on the list. SIM Toolkit or Services & feedback (sometimes the menu is hidden there).
- π Select Notifications and completely disable the slider Allow Notifications.
- π« Additionally, click Other permissions and disable display over other windows.
βοΈ Checking notification settings
After these steps are completed, the system will stop showing banners and beeps from the SIM card. However, the menu itself may still open at certain triggers, for example, when rebooting the phone. To minimize the risks, it is also recommended to clean the application data by resetting it to factory settings inside the property menu.
β οΈ Attention: Do not remove the app cache SIM Toolkit is too frequent as it can cause roaming settings to reset or re-register on the operatorβs network, temporarily depriving you of communication.
Limitation of background activity and battery
Modern versions of Android on Xiaomi devices have aggressive power-saving algorithms that you can use to your advantage. By limiting the SIM card application to resource consumption, you effectively βsleepβ it down, preventing spontaneous launch, especially for models with large amounts of RAM, where background processes live long.
Go to Battery and Performance (or just Battery in the new HyperOS versions). Find the SIM Toolkit application list. Here you need to change how the system works with this process. The standard No Limits mode allows the application to run constantly, which we don't need.
Select the option Saving energy or Hard Limit, which will prevent the application from running in the background without your knowledge, and it is also worth turning off autostart if this option is available in the advanced battery settings, the system will block the attempts of the Tele2 menu to activate without user intervention.
π‘
If the standard battery settings don't help, try setting a background limit in the Developer menu. Find the "Background Process Limit" and set the "No More than 2 Processes" value to make it faster to unload unnecessary services.
The effectiveness of this method depends on the version of the operating system. On older versions of MIUI (before version 12), the restrictions worked more strictly, while new versions may ignore some prohibitions for mission-critical system services.
Use of Developer Mode and ADB
For advanced users who want to get rid of the menu guaranteed, there is a method of forced debugging via USB. This method does not require root rights, but requires a computer and a cable. With the ADB tool, you can remove the application for the current user, effectively making it invisible to the system.
First, activate the developer mode. To do this, quickly click on the MIUI version number seven times in the About Phone section. Then, in the Developer menu that appears, turn on USB Debugging. Connect the phone to your computer and install the Xiaomi USB Driver drivers.
adb shell pm disable-user --user 0 com.android.stk
adb shell pm disable-user --user 0 com.android.simappdialogExecuting these commands in the command line (after going to the folder with ADB) will disable the standard SIM toolkit. If you need to return everything back, use the command with the replacement of disable-user with enable. This is the most radical and effective method.

Use of the ADB-Pm Disable-user commands are the only way to hide them completely SIM menu without flashing the device, while maintaining a guarantee at the software level.
Be careful when typing commands. A bug in the packet name can cause other important system components to shut down. Check the syntax carefully before pressing Enter. If you are unsure of your actions, you should use the milder restrictions described above.
Comparison of problem-solving methods
To make it easier for you to choose the right way, we have a comparative table, each method has its pros and cons depending on your technical background and desired result, some methods are safer, others are more effective.
| Method | Difficulty | Efficiency | Risks. |
|---|---|---|---|
| Disabling notifications | Low. | Medium | No. |
| Battery limitation | Low. | Medium | Minimum |
| Hiding through ADB | Tall. | Tall. | Average. |
| Removal (Root) | Critical | Complete. | Tall. |
As you can see from the table, for the average user, the best solution is to combine disabling notifications and limiting background activity, which gives 90% of the result without the risk of damaging the system, and the ADB method should be used only if other methods did not help.
Remember that Tele2 software can be updated and settings can be reset after the phone firmware update, in which case you will have to repeat the setup procedure.
Frequent errors and additional recommendations
Users often make common mistakes during the setup process that negate all efforts, one of the most common being trying to remove an application through third-party cleaners, often with little authority and can only create a semblance of operation, leaving system processes active.
Another mistake is ignoring system updates. Xiaomi engineers regularly release security patches and stability improvements that may affect the operation of communication modules. Before you take drastic measures, make sure that your version of MIUI is up to date.
β οΈ Warning: Never attempt to delete system files manually through root-access file managers unless you know the exact purpose of each file.This can lead to a cyclic phone restart (bootloop). If your Xiaomi has two SIM cards installed, the settings should be applied separately for each slot. SIM 1 and SIM 2 may have different identifiers in the system, although most often they are combined into one process. By removing unnecessary visual noise, you not only increase the comfort of use, but also save a little battery power, as the processor spends less resources on rendering unnecessary windows (FAQ) Is it safe to turn off completely? SIM Toolkit through ADB? Yes, it is safe for the hardware of the phone. You don't lose the connection, you don't lose the ability to call or go online. You only shut down the service management software interface. You can turn it back on by enabling or resetting your phone to factory settings. Is your balance or money gone after you turn off the menu? No, the balance and connected tariff plans are stored on the operatorβs side. Tele2, It's not in an app on your phone. Turning off the menu has no effect on your finances or your account. Could this menu be a virus? SIM Toolkit is a system component of the standard GSM, But scammers can use similar names for malware, and if an application requires strange permissions or comes from an unknown source (not from the system), you should check the phone with antivirus. Tele2 Reappears again after the update? When you update the operating system or the Service Feedback application itself, the settings can be reset to factory settings, and you will need to re-execute the notification or battery restriction procedure.
