How to change a name SIM-Xiaomi maps: The full guide

Xiaomi smartphone owners often face the need to personalize their device’s interface to make it more user-friendly.One such setup is renaming SIM-This is especially true for users who use two numbers at the same time"SIM 1" or "China Mobile" are not always informative, and replacing them with clear labels such as "Work", "Personal" or "Internet" makes navigation much easier.

Changing the name of the MIUI SIM card and the new HyperOS is simple, but it has its own features depending on the software version. In this article, we will analyze the algorithm of actions, discuss the nuances of working with two active communication modules and answer frequently asked questions. You will learn not only to change text tags, but also to adjust the color coding for quick visual identification of the active number.

It's worth noting that the correct name helps avoid accidental errors when making calls or sending messages. When a call log or contacts display an understandable operator name or number destination, the user does not have to guess from which card the call was made. This is a basic but important ergonomics setting for your smartphone.

Why you need to rename SIM cards on a smartphone

The main reason why it's worth spending a minute setting up SIM card names is because of the convenience of everyday use. SIM-But in real life, we use the categories of "primary number," "work phone," "roaming card," or "internet fare," replacing abstract numbers with clear words reduces cognitive load.

Visual identification also helps you navigate system notifications more quickly, so if you miss a call or a new message in the notification curtain, you can see which number you're getting, and this is especially important in situations where you need to make a quick decision about how to respond without looking at the lock screen for too long, and personalizing the interface makes interaction with the technology more natural.

⚠️ Note: The SIM card name change only happens locally on your device.The subscriber you call will still see your regular phone number, not the name you invented.This is a customization solely for your comfort.

And then there's color labeling, which is often paired with renaming, and by assigning different colors to different names, you create a strong visual association, like blue for work and green for personal contacts, which allows you to instantly read information to your peripheral vision, which increases the overall efficiency of your smartphone.

Preparing for changes in network settings

Before you start to change the settings directly, you need to make sure that the device is ready to make changes. First of all, the SIM cards must be physically installed in the tray and determined by the system. SIM-"Put in the cards" or "Put in" SIM", You'll have no place to edit her name, see if the switches in the settings menu are activated.

It is important to understand that the menu interface may vary slightly depending on the version of Android and the MIUI shell. However, the logic of creating the menu remains the same for all Xiaomi, Redmi and POCO models. You do not need superuser rights (Root) or connection to the computer. All actions are performed by the operating system’s regular means through the Settings application.

It is also recommended to make sure that there are no third-party launchers on the screen that can hide standard menu items or change their location. Although in 99% of cases the standard settings application is always available, some aggressive design themes can hide certain interface elements. If you can’t find the right item, try temporarily switching to a standard design theme.

Step-by-step: renaming the SIM to MIUI and HyperOS

The process of changing the name of the SIM card on Xiaomi smartphones is quite linear and does not require deep technical knowledge. Follow the algorithm to successfully complete the task. All actions take no more than one minute.

  1. Open the main application menu and find the Settings icon (cog).
  2. In the list that opens, find the section SIM-maps and mobile networks. In some versions of the firmware, it may simply be called SIM-maps or be inside the Connection and Sharing section.
  3. The screen will display the cards installed. Click on the SIM card you want to change (usually signed as SIM 1 and SIM 2).
  4. In the settings menu of a particular card, find the Name or Network Name field, and by default, the operator name (e.g., MTS, Beeline) or the standard β€œSIM 1” can be indicated.
  5. Tap this field. The system keyboard will open. Type the name you want using letters, numbers and valid characters.
  6. Click the OK button or tick to save the changes made.

Once saved, the new name will instantly appear in the status bar (if the names are displayed in the curtain) and in the call log. If you have a HyperOS shell installed, the visual design of the menu may be more minimal, but the sequence of actions remains identical, the main thing is to find the item responsible for the specific SIM card slot.

Use short, capacious titles, up to 10-12 characters long, and long titles can be cut in a status bar or call log, turning into unreadable text.

It is worth noting that in some regions or on some versions of firmware (especially global ones), the path may be slightly different. β†’ The phone. β†’ Double applications (rare case), but the standard way through SIM-Maps and mobile networks are universal to the Xiaomi ecosystem.

Customization of color labels and visualization

Along with the text name, the system suggests assigning a color ID to each SIM card, a powerful visual navigation tool, so when you make a call or send a message, the system illuminates the button or indicator with the appropriate color, allowing you to instantly know which channel will go through.

To adjust the color, follow the following steps:

  • 🎨 Go to the SIM card settings menu as described in the previous section.
  • πŸ”΅ Find the Color or Color Mark item.
  • 🟒 Choose one of the colors from the palette. 6-8 base-colour.
  • 🟣 Repeat the procedure for the second SIM card by choosing a contrasting color for maximum distinguishability.

Color encoding extends not only to the call screen, but also to the contact list, the history of calls and messages, for example, the incoming call to the "Work" number will be illuminated in blue, and the "Personal" - green, this helps to navigate even without reading the text, but only by looking at the screen, in bright sun or in poor vision, this function becomes indispensable.

It's important to choose the right contrasting colors. You should not choose the same or close shades (for example, light green and dark green) for different maps, because this will negate the whole point of visual separation. The optimal use of opposite colors of the spectrum: red and blue, yellow and purple. This ensures maximum interface differentiability.

The combination of a unique name and contrasting color creates a dual identification system, reducing the risk of error when calling to zero.

Managing two SIM-mapping

Xiaomi smartphones traditionally support the operation of two SIM cards in standby mode, and many modern models and in simultaneous operation 4G/5G. With two active numbers, managing them becomes more difficult, and here the advanced settings available after renaming come to the rescue.

On the menu. SIM-Maps and mobile networks can set rules of behavior of the device:

  • πŸ“ž Calls: Choose which card to use by default, or set the request each time, and you can assign a specific card for certain contacts.
  • 🌐 Mobile Internet: Specify which SIM card (by name) data traffic should go through.
  • πŸ’¬ SMS: Similar to calls, you can select a priority card to send messages.

Always Ask is the most flexible feature, but can be annoying when you make frequent calls. If you have clearly separated card functions (e.g., "Work" - only calls, "Home" - only the Internet), it is better to set the appropriate settings by default, which will eliminate unnecessary actions and speed up interaction with your smartphone.

⚠️ Note: When switching mobile Internet from one SIM-This is a normal modem behavior when you restructure the network, and it doesn't require user intervention.

It is also worth mentioning the function of "Smart replacement". SIM-If the main SIM card for the Internet stops catching the network (for example, you left the coverage area), the phone can automatically switch to the second card if this feature is activated. However, with manual renaming and rigid division of roles, it is better to monitor this yourself, so as not to waste traffic from an unintended map for this.

Possible problems and solutions

Despite the simplicity of the procedure, users may encounter a number of typical problems, most often related to shell software failures or carrier features, and we will discuss the main ones and how to fix them.

One of the common problems is the inability to save a name or automatically reset it to a factory value when you reboot it, which can occur if the system settings file is corrupted or the application cache is overflowing.

  • πŸ”„ Reboot: A banal but effective method: Reboot your smartphone and try renaming the map.
  • πŸ—‘οΈ Cache Clearing: Go to Settings β†’ Annexes β†’ All applications β†’ Find the settings (or phone number) β†’ Memory. β†’ Clear the cache.
  • πŸ“Ά Slot change: Try physically moving the SIM cards to another slot.Sometimes the problem lies in the tray contacts.
What if the name is reset after each reboot?
If the SIM card name is constantly reset, it may indicate a deeper problem with firmware or third-party conflict. Try booting in Safe Mode. If the problem disappears in Safe Mode, then one of the installed applications is to blame. Uninstall recently installed programs, especially those that have access to the phone and SMS. If this does not help, you may need to reset to factory settings, but first make a backup of the data.

Another situation is displaying strange characters instead of a name, which often happens if the operator sends specific control messages or if the name uses rare fonts. In this case, try using only Latin letters or standard numbers. Cyrillic characters are not supported by all operators and not in all regions, so using the Latin alphabet (Translit) is often a more reliable option.

If you upgrade to a new version of MIUI or HyperOS and the interface is gone, don't panic. Google and Xiaomi periodically change the location of menu items for minimalism. Look for the "Mobile Network" section or search for the settings by typing the word "SIM." Search by settings is the fastest way to find the right item in the confusing menus of new versions of Android.

Using the Latin alphabet for naming SIM cards guarantees compatibility with all operators and no problems with encoding characters in any situation.
