How to remove the phone number from SIM-maps on Xiaomi Redmi

Many owners of Xiaomi and Redmi smartphones face a situation when they are replaced by a new smartphone. SIM-And when you're doing a card or data transfer, you get extra entries in the phone book, and often these are old contacts that have automatically synchronized with the carrier's chip, and now they interfere with normal use of the device. MIUI There are some nuances that often put users at a loss.

The problem is that the default system tries to keep all new contacts at once. SIM-If you change the number or just want to clean the chip memory of outdated information, standard deletion through the contact list may not work, as the record will return from the cloud or cache of the system. You need to understand the difference between a contact stored in a phone’s memory and a record physically stored on an operator’s chip.

In this article, we will discuss in detail how to properly manage the list of contacts stored directly on the site. SIM-You'll learn to distinguish between data storage sources and get rid of unnecessary duplicates that take up space and create confusion when calling. We'll look at both the standard shell tools and the hidden settings available to advanced users.

Why are your contacts duplicated and saved on SIM?

The main reason for the appearance of extra numbers lies in the logic of the Android operating system in conjunction with the shell. MIUI. When you first switch on your smartphone or insert a new one SIM-The map, the system often suggests importing contacts. If you agree, all the records are copied, but there may be links to the source, the synchronization takes place in the background, and if the source has not been cleared, the contacts return.

Another important aspect is the limitation of the SIM-CPUs have very little memory and an outdated file system, and they're not designed to store a lot of data, like photos, email addresses, or multiple numbers for a single name. SIM, The system either crops data or creates multiple records with the same name, which visually looks like an error.

⚠️ Attention: SIM-The card has a limit on the number of characters in the name (usually up to 20) and does not support Cyrillic in some older storage formats, which can lead to the appearance of “crackers” instead of names.

Also worth mentioning is the “smart” save feature in Xiaomi. By default, the phone can offer to save a new number in several places at once: in Google account, in device memory and on the phone. SIM-This is done for security, so that data is not lost when you lose your phone, but for the user who wants to delete the number from the SIM, this forethought becomes a problem that requires manual cleaning of each source separately.

Understanding the structure of data storage is key to success. SIM-The card is used primarily to identify the operator in the network, rather than as the main repository of the phone book, so deleting numbers from it is more of a maintenance procedure than a daily task.

Preparation for disposal: checking storage sources

Before we start taking radical steps to clean up the chip, we need to know exactly where a number is stored. In the standard Contacts app on Redmi, all the records are often mixed together, creating the illusion of a single list, in fact, each record has a source, and you need to delete it from it.

Open the Contacts app and find the number you're interested in in the list. Click on the contact name to open the detailed card. The top of the screen or the editing menu (pencil icon) often shows where that contact is saved. This can be written in small print, such as: “Retained in: SIM 1" or "Save to: phone. If it says Google or Xiaomi Cloud, delete from the SIM-The maps will not help here, you need to change the synchronization settings.

For more detailed analysis, you can use the display filter. In the contact app, click on three dots in the corner or the menu button, then select "Display settings" or "Contacts to display." Here you can temporarily disable the display of contacts from the memory of the phone and the cloud, leaving only the SIM-This will allow you to see the actual list of what's physically written on the chip.

💡

Use the Favorite feature for important numbers before cleaning so that you don’t accidentally delete the contacts you want during the source sorting process.

It is also important to check whether automatic sync is enabled with other services such as WhatsApp or Telegram. SIM-The first time you run the cards, you create your own records that will be displayed in the general phone book. Deleting the original from the SIM in this case may not remove the contact from the messenger, but will clear the main base.

Instructions: Step-by-step, delete numbers through the standard menu

The easiest and safest way to delete a number is to use the built-in MIUI shell, which does not require third-party software installation and is suitable for most users, and the main thing is to carefully monitor which contact you choose to delete so as not to erase important data from the cloud.

Open the standard Contacts app first, a yellow icon with a human silhouette. Go to list editing mode, usually by long-pressing one of the contacts or by clicking the "Select" button at the bottom of the screen. If you need to remove all numbers from the SIM at once, you can use the “Select All” function, but filtering the display only by SIM-map.

Once you have selected the numbers, you'll see a toolbar on the screen, and you'll find and click the Remove button, and the system will give you a warning window asking for confirmation of action, and you'll need to read the text of the notification, if it says, "Delete contacts with the user." SIM-If you're on the right track, if you're talking about a Google account, stop and check the source again.

In some versions of MIUI, the process may be different. If there is no direct removal, try to enter the edit mode of a specific contact, click three dots in the corner and select Copy or Move. By moving the contact to the phone's memory, you will free up space on the SIM and then be able to safely delete the original, which is especially true if the system blocks direct deletion due to system constraints.

Contact management via engineering menu and SIM settings

For more in-depth work with the content SIM-Xiaomi has a separate settings section dedicated to managing the card itself, where you can not only delete the numbers, but also see the technical information about the memory filling of the chip.

Go to the main "Settings" of the phone (cog icon). Find the "About Phone" section or immediately «SIM-maps and mobile networks, depending on the Android version and MIUI, The path may be slightly different, but the essence is the same: you need to find the item “Contact on the Internet”. SIM-map" or "Contact management SIM». Clicking on it, you will get to a specialized interface.

The list that opens will only show the records that are physically on the chip. There are no cloud syncs or take-ups from the phone's memory. You can select a specific number and click "Delete" or use the menu button for mass removal. The interface here is simplified, without unnecessary decorations, because it's a system tool.

Using third-party applications for deep cleaning

Xiaomi’s regular tools are functional, but sometimes limited. If built-in techniques don’t allow you to delete certain secure or system records, third-party apps come to the rescue from the Google Play Store, provide more flexible tools for managing the phone book and work at the contact database level.

One of the most popular and trusted solutions is Google’s Contacts app, which is often already installed on the system, but hidden or not used by default. Google Contacts interface makes it easy to switch between all contacts, phone and other tabs «SIM-This is where the deletion is instantaneous and syncs with all devices if the appropriate option is selected.

Another powerful tool is a tool called a cleaner application like Clean Master or a specialized contact manager like Contacts+, which can find duplicates, merge records, and massively delete contacts from those media, but be careful: these applications require broad permissions to access your personal data.

When using third-party software, pay attention to access rights. Permits should only include reading and writing contacts. If an application requires access to a microphone, geolocation or SMS without an obvious need, it is better to abandon its use in favor of more secure analogues. Data security is paramount in the digital age.

Third-party applications give more control, but require careful verification of the developer’s access rights and reputation.

Solving problems: if the number is not deleted or returned

There are times when you delete a number, you reboot your phone, and it reappears on the list, and that's a classic sign of active sync with a cloud service, most commonly Google Account or Mi Cloud, and the phone sees that there's a record in the cloud and it's on the cloud.

Find Contacts, click Clear, and select Clear Cache (not data if you're afraid of losing settings, although contacts are usually stored in the database.

In rare cases, the problem lies in physical damage. SIM-Older cards may have damaged memory cells that the system cannot overwrite correctly, and in this case, the deletion seems to occur, but the next time the card is read, the card returns the old data due to a read error. SIM-card with the operator with the preservation of the number.

To sum up, managing contacts on Xiaomi Redmi requires understanding where information is stored. SIM-The map is a thing of the past in terms of data storage, and the modern approach involves the use of cloud services. SIM-Cards from numbers help avoid confusion and speed up the phone book, making smartphone use more comfortable.
