Owners of Xiaomi Mi 9 smartphones often face a situation where standard system settings do not allow to reveal the full potential of the device. Changing the geographical position in the menu is not just a formality, but a powerful tool for removing embedded advertising, gaining access to exclusive topics and activating work. NFC-The global version of firmware may have limitations that can be easily avoided by simply changing the parameter in a hidden engineering menu or standard settings.
This process is safe and does not require root rights or unlocking the bootloader, which retains the official guarantee. However, before you start manipulating, you need to understand what changes will occur in the interface and application operation. The correctly selected region allows you to adapt the behavior of the MIUI operating system to the specific needs of the user, whether it is minimalism or maximum functionality.
In this article, we will take a look at all the available methods of relocation, from simple menu switches to the use of engineering mode. You will learn which countries are best suited to disable advertising services and which regions are necessary for banking applications to work correctly. Changing the region to India or Indonesia is the most effective way to completely disable system advertising on global firmware.
Why change the region to Xiaomi Mi 9
The main reason users use this procedure is to get rid of intrusive ads in standard applications. MIUI is monetized through displaying ads in menus, browsers and app installs, but display algorithms are often tied to specific geographic areas. By changing the location to a country with a less aggressive advertising policy, you will noticeably clear the interface.
The second important aspect is the work NFC-chips and payment services: Some regions have defaulted on protocols that may conflict with local banking applications or contactless payment services. Moving to the US or Singapore region often solves card identification problems in apps like Google Pay or Mi Pay.
The region change also gives you access to additional features in the Themes and Wallpaper app, where the content store dynamically loads collections based on your location, for example, users who choose India often access unique live wallpapers and fonts that are not available in the European or Russian version of the store.
Preparation of the device before making changes
Before making any changes to the system settings Xiaomi Mi 9, it is recommended to perform a number of preparatory steps, which will avoid loss of important data and ensure the stability of the system during the reconfiguration process. While the procedure is safe, neglect of basic digital hygiene rules can lead to unforeseen failures.
First of all, make sure that the battery is at least 50%, the process of changing system parameters may require rebooting services or the device itself, and a sudden power outage at this point is undesirable, and it is also worth checking for free space in internal storage, as some regions may require loading additional language packs or resources.
☑️ Checklist of preparation Xiaomi Mi 9
Make sure to back up important contacts and photos. Use Mi Cloud or sync your data to your Google account. This is a standard precaution when you manipulate your smartphone system settings. In rare cases, you may need to reset your network settings, which will affect stored Wi-Fi passwords.
⚠️ Warning: Before changing region, be sure to unplug your device from your Mi Account if you plan to unlock the bootloader in the future.Basing to a new region can change your server account, making it harder to unlock the bootloader.
Change the region through the standard settings menu
The easiest and safest way to change the geographic location is to use a regular settings menu. This method does not require installing third-party software and is available to every owner of the Xiaomi Mi 9. The interface may vary slightly depending on the version of MIUI, but the logic of actions remains the same.
To start, open the main menu and find the Settings icon. You'll need to go to the "Advanced" section, which is often indicated by a three-dot icon or a gear, and that's where the settings for language preferences and regional system standards are hidden.
In the list that opens, look for Region. Click on it and you'll see a long list of countries. Scroll down to the right number. Most users will choose the United States, Singapore or Nepal. Once selected, the system may need to reboot to apply the changes.
- 🌍 USA – ideal for unlocking additional frequencies and settings NFC.
- 🇮🇳 India is the best choice for completely disabling advertising modules in the system.
- 🇸🇬 Singapore – Balance between functionality and no software noise.
- 🇷🇺 Russia/Ukraine/Kazakhstan – standard settings with full set of local services.
What happens when you change the region in the settings?
Use of the Engineering Menu for Advanced Users
For those who want to access the hidden functions of the radio module, there is an engineering menu, a powerful diagnostic tool that allows you to manage settings. SIM-And be careful, changing unknown parameters can cause a loss of signal.
To get into the engineering menu, open the Phone app and dial the combination ##4636##. If the code didn't work, your firmware version may be blocking that entry, so you can use the Activity Launcher app from the Play Market store to find Testing activity.
In the menu that opens, select "Phone Information." Here you can see the current network status and IMEI. An important parameter is "Set Preferred Network Type." Changing this parameter can help lock your smartphone into 4G/LTE mode, which is often required when you have problems switching to 3G in certain regions.
The sequence of actions in the engineering menu:
1. Phone Information
2. Running Service (load check)
3. Usage Statistics (Usage Statistics)
4. Wi-Fi Information (wi-fi connection details)⚠️ Note: Do not change settings in the "Radio Power" or "Radio Power" sections"IMEI", If you are not a qualified professional, an error in setting may result in software blocking the communication module.
The impact of the region on the work of NFC and Google Pay
The NFC contactless payment feature on the Xiaomi Mi 9 is directly dependent on the selected regional settings. The smartphone antenna operates in different frequency bands, and the software needs to know which standards are prioritised in your locality. The wrong region can lead to the terminal simply not seeing the phone.
If you notice that payment has stopped or the Google Pay app is giving you a compatibility error, try changing your region to "US" or "UK." These settings are often the most versatile for emulating cards. After changing region, be sure to clear the wallet app's cache and add a map.
Also, some banking applications may block devices from a region other than the country of issue, a security measure that compromises using the bank region to run the apps and switching to Indonesia only to clear ads when needed.
| Region | Advertising in MIUI | NFC work | Available topics |
|---|---|---|---|
| Russia | Present. | Stable. | Local. |
| India | Minimum | Requires a check-up. | Extended. |
| USA | Absent. | Great. | Global |
| China | Lots (Chinese) | Limited. | Chinese |
💡
For maximum compatibility with payment systems and minimization of NFC errors, it is recommended to install the "US" or "Singapore" region, as these settings are the most neutral and universal.
Decision after location change
After changing the region, users may encounter a number of typical situations that are not errors, but only features of the MIUI. For example, the format of the display of the date and time may change, or the holidays of the selected country will appear in the calendar.
Sometimes there is a temporary slowdown in the speed of the Internet connection, which is due to the fact that the smartphone re-registers on the network with new parameters, just turn on the flight mode for 10-15 seconds and turn it off, so that the communication module re-established the connection with the base station with updated settings.
If your voice assistant is missing or you're starting to speak another language, check the settings of the Google Assistant app. Changing the system region may reset your language model preferences. Return the language you want to use in your voice input settings to restore the correct operation.
