How to disable the Xiaomi SIM card menu: solving intrusive notifications

Owners of modern smartphones Xiaomi, Redmi and POCO Often faced with an annoying situation: after each switching on the device, reboot or exit from the coverage area on the screen suddenly pops up a system window with a suggestion to configure the device. SIM-This is what's called the SIM card menu, which is called the Android operating system. SIM Application Toolkit (STK). It is designed to manage the services of the operator, but in modern conditions often becomes only a source of visual noise.

The problem is that standard interface methods MIUI It's not always possible to completely ban this window, or HyperOS, and it insists on choosing a SIM card for calls or the Internet, even if you've already decided on your preferences. SIM-Nano-SIM cards or chip contacts damage, and in this article we will look at all the effective ways to fix this problem, from simple settings to deep resetting of network parameters.

Ignoring these pop-ups can lead to them blocking important notifications or interfering with touch screen usage at a critical time. Understanding how the interaction between the base station and your device works will help not just close the window, but eliminate the cause of its appearance forever. We will look at both the software methods and the physical aspects of the communication module.

The reasons for the appearance of the SIM-menu on Xiaomi smartphones

Before we take any action, we need to understand the nature of this system request. The MIUI shell is based on Android, where a special service is responsible for interacting with the cellular module. When the phone registers with the operator's network, it receives not only a signal, but also a set of commands for the service menu. If these commands contain triggers to launch the interface, a setting window appears on the screen.

Often, the situation is aggravated by updating the firmware or changing the region in the settings, the system may perceive the new configuration as a primary installation and require confirmation of network parameters. SIM-cards that are not fully compatible with modern communication standards 4G/LTE and 5G. In such cases, the phone tries to “negotiate” with the card, launching a dialog box.

There are a number of specific factors that trigger the system, and the main ones are:

• 📱 Physical contact: Oxidation of contacts SIM-The card or tray leads to a short-term break in the connection, which the system considers as the card extraction and requires reconfiguration.
• 📡 Weak signal: In unstable reception areas, the phone is constantly re-registered on the network, which can initiate a repeat request STK-menu.
• ⚙️ Priority Conflict: If the default device for mobile data is not selected in the settings, the system will ask about this every time it connects to the network.
• 💾 Cache of telecom services: Accumulated errors in the operation of system applications"SIM-Maps can cause cyclical window appearance.

⚠️ Note: If the SIM card menu appears immediately after the installation of a new card from another operator, this may be a normal reaction to the activation of new services.

Understanding the cause allows you to choose the most gentle method of solving, for example, if the problem is contacts, then software resets will not help, and you need to clean the tray. If it is a software conflict, then you can help us with system settings.

Basic setting of priorities SIM-map

The first step in combating intrusive notifications should be to check the phone's basic settings. Often users ignore the SIM management section, relying on automatic system selection. But this is where the key to solving the problem of persistent requests lies. You need to manually record device preferences.

To do this, go to your Xiaomi’s settings menu. Find the Settings section, then select the item. SIM-Maps and mobile networks. In some versions of the firmware, the path may be different: Connections and sharing -> Two. SIM-So, the critical thing here is to check two parameters: "Calls" and "Mobile Internet".

Make sure that both options are SIM-specific, rather than always ask. If you always ask, the phone will have to open the selection menu for every action that requires a network.

• 📞 Voice calls: Select the main SIM card you use most often.
• 🌐 Mobile data: Specify the card with unlimited or largest packet of traffic.
• 💬 SMS: Record the card, which comes with the confirmation code from banks.

When you change your settings, make sure you restart the device, so that the system can keep the configuration in the preference register and stop polling the user at every opportunity, and if the problem persists after the reboot, then we can move on to deeper methods.

💡

Use Flight Mode before changing SIM settings. Turn on Air Mode, change map settings, turn off Air Mode, and help the network re-register the device with the new settings.

Resetting mobile network and APN settings

If manual prioritization didn't work, it's likely that the system has accumulated errors in the APN profile or network stack configuration, and resetting those settings to factory values often works wonders by eliminating software glitches that cause the SIM card menu to appear, a secure procedure that doesn't affect your personal files.

To perform the reset, you will need access to a hidden or standard access point settings menu -> SIM-Maps and mobile networks. Select an active SIM card, then click on Access Points (APN). In the upper right corner of the screen (or in the lower, depending on the version). MIUI) Find a menu with three points or a gear.

In the menu that opens, select Reset APN or Restore by default, and then the system will clear all user Internet access settings for cellular communications and replace them with standard ones received from the operator, which eliminates configuration conflicts.

You can also do a full network reset, which will bring all of the Wi-Fi, Bluetooth and mobile settings back to their original state, and you'll have to re-enter the Wi-Fi passwords, but that's guaranteed to eliminate the bugs in the communication module.

After doing this, the phone can search for a few minutes. Don't worry, this is a normal process of re-registration in the operator's cell. If the menu stops appearing, then the problem was in the wrong network profiles.

Cleaning the cache of SIM system services

In the Android operating system, SIM cards are handled by special system applications, which have no desktop icons, but are active in the background, sometimes their cache gets overflowed or corrupted, which leads to a cyclical launch of the configuration interface, and clearing these services' data is a powerful tool for solving the problem.

To get to hidden system processes, go to Settings -> Apps -> All Apps. In the upper right corner, click three dots and select Show System Processes. Now, in the list, you need to find apps with names that contain the words "SIM," "Telephony," or "Phone."

The most important for us are:

• 📱 SIM-Toolkit: The main application responsible for the service menu.
• 📞 Phone: Systemic process of call processing.
• 📡 Google Play Services: Sometimes Cache Network Settings.

Once you enter the properties of each of these applications (e.g. SIM-Toolkit), click Clear -> Clear cache and then Clear everything (or "Reset"). Don't worry, your contacts and SMS won't be deleted, as they're stored in another section. You only reset temporary files and error logs.

⚠️ Warning: When cleaning your phone or contact system application, be very careful to ensure that your contacts are synced with your Google or Mi Account account so you don’t lose important numbers.

Once the cache is cleared, force all open applications to be closed and complete a full smartphone reboot, which will force the system to reinitialize the communication services from scratch.

Physical diagnosis and maintenance SIM-map

And you can't rule out the physical factor, and often the software glitches are just the result of poor contact between the gold contacts. SIM-If the phone loses touch with the card for even a fraction of a second, it immediately tries to "configure" it again, displaying the corresponding menu.

Remove the SIM card tray with a paper clip. Carefully examine the card itself. If it's hand-cut from Micro or Standard format in Nano, the edges may have been touched, or the card may be too thick, often stuck or poorly contacted.

The following actions are recommended:

• 🧼 Cleaning contacts: Gently wipe the gold chip SIM-cards with a soft rinse or cloth slightly soaked in alcohol.
• 🔄 Slot change: Try moving the card to another slot (SIM 1 in place SIM This will help you understand whether the problem is in a particular card or in the phone connector.
• 🆕 Replacement of the card: If the card is more 5-7 In the years since, she's been out of service, you can call the operator's cabin for a free replacement. SIM-number-card.

Also check the phone tray itself. There should be no dust, pile or foreign objects inside, and sometimes even a microscopic villi interferes with the tight fit of the card, causing permanent breaks in the connection.

Use of engineering menu and additional commands

For advanced users who have not been helped by standard methods, there is an option to interfere with the radio module through an engineering menu, which is a hidden part of the system that is designed to test the hardware, and you can force the network modes to be reconfigured.

Open the Phone app and enter the code ##4636##. If the code works, the Testing menu will open. Select Phone Information. Here you can see the status. SIM-maps and current network type.

You can try switching your preferred network type from this menu, for example, if you want LTE only, try returning LTE/TD-SCDMA/WCDMA. Sometimes fixing on one standard causes conflicts with the operator menu, but beware: the wrong settings can temporarily deprive you of communication.

If the standard code doesn’t work on your version of MIUI (which is often the case in global firmware), you can try using ADB commands via a computer, but this requires a PC and debugging skills. For most users, the previous steps will be enough.

💡

The engineering menu is a powerful tool, but only use it if you understand what you're doing. SIM-Cards solve the problem in 95% of cases without the risk of disrupting the modem.
