How to remove numbers from SIM-maps on Xiaomi

Changing your smartphone or switching to a new plan is often accompanied by the need to clean up the phone book. Owners of Xiaomi, Redmi and Poco devices often face a situation where, when reshuffling, they are not able to do so. SIM-Old records are duplicated or occupy limited space on the chip. Deleting numbers directly from the SIM card is not just a way to free up space, but also an important step for synchronizing data in a single cloud space.

Modern smartphones offer flexible contact management tools, but the standard menu sometimes hides the desired features or makes them unobvious to the beginner. Many users mistakenly delete numbers from the general ledger, not realizing that the copy remained on a physical medium. In this article, we will discuss in detail how to properly clean the SIM card memory, transfer important data to the cloud and avoid losing valuable information in the process.

Before you start taking drastic measures, make sure you really want to delete numbers forever, rather than just hide their display. MIUI and HyperOS have their own storage features that you need to consider. Proper contact management will allow you to quickly find the number you want and ensure that the database is clean when you switch to other devices.

Preparation for cleaning and backup

The first and most critical step is to preserve important data. SIM-The card is limited and often does not support storage of additional fields such as email, address or photo. Before you start deleting contacts, it is strongly recommended to transfer all records to the phone's internal memory or, even better, to a Google account. This will ensure the safety of data even in case of a device breakdown or loss of the SIM card.

To start, open the Contacts app and go to settings. Here you will find the import and export option. SIM-It takes only a few seconds to process, but ensures that no important number is lost irrevocably. If you plan to sell your phone or transfer your SIM card to another person, this step is a must.

It's worth noting that when you transfer to a SIM, you often cut off long names and lose extra numbers. So the reverse process -- cleaning up the SIM and storing everything in your phone -- is a more modern and reliable approach. A SIM card only stores the base number and name, so storing the entire base on the chip is considered an outdated method.

Removing contacts through a standard application

The easiest way to remove SIM card entries on Xiaomi is to use the built-in Contacts app. The interface may vary slightly depending on the version of MIUI, but the logic of the action remains the same: you need to open the app, click on three dots in the corner or the “More” button and select “Import and export contacts”.

In the menu that opens, select the option "Delete contacts." The system will tell you to choose the source from which to erase data. Here it is important to be careful: if you choose "All contacts", then delete the records from the phone's memory too. SIM-map SIM 1 / SIM 2, depending on which slot to clean from.

• 📱 Open the Contacts app on the home screen.
• ⚙️ Go to the settings menu via the “More” button or three dots.
• 🗑️ Select “Delete Contacts” and specify the source «SIM-map».
• ✅ Confirm the action by ticking “Select all” or specific numbers.

Once the operation is confirmed, the system will alert you to the irreversibility of the action. This is the standard security measure of Android. If you have previously made a backup, you can safely confirm the deletion. Some versions of the firmware may require the introduction of the device. PIN-Screen unlock code to confirm access rights.

Using Google Contacts to Manage

An alternative and often more convenient method is to use Google Contacts, which is especially relevant if you are used to syncing data with the cloud, and you can not only delete but also manage duplicates through a web interface or a separate application, which is often found after transferring data from old phones.

Go to your phone's settings, look for Accounts and Sync, and make sure that your contacts sync is enabled. Then open the Google Contacts app (a separate A icon or browser). SIM-Here you'll see a list of all the numbers saved on the chip.

For mass removal, select the desired number or use the function of selecting all contacts on the site. SIM. Then click the delete button (basket icon), and the advantage of this method is that the changes are instantly reflected in all devices associated with your account, although the account itself is not the same. SIM-map and is a local storage, the phone will update the list display.

Cleaning through the engineering menu and settings

In the rare cases where standard methods don’t work or the interface is blocked, you can use deeper system settings. However, be careful: incorrect actions in the system menu can lead to unstable operation of the communication module. On Xiaomi devices, the classic engineering menu (#4636##) is primarily designed for testing the network, but contact management there is limited.

A safer way through settings is to manage applications. Go to Settings → Apps → All apps. Find Contacts and Contact Storage. Here you can try clearing the cache, but not the data, unless you want to lose everything at once. For direct deletion of SIM numbers, this method is less effective than the standard application, but useful for resetting display errors.

If the numbers are “hang” and are not deleted, try the following algorithm:

1. Extract. SIM-card and paste it into another, preferably simple phone (button-button).

2. delete contacts through the menu of the phone book of the old device.

3. Return the card to Xiaomi and import the leftovers into the phone, after which clear the SIM again.

Data portability and elimination of duplicates

A common problem with users is having the same numbers in their phone's memory and on their SIM card, which creates confusion: when they call, they show two identical contacts. SIM-The card must be audited by the main base. MIUI It has a built-in tool for combining duplicates.

Open contacts, click on the menu, and select "Contact Organization" or "Combine duplicates." The system automatically finds the duplicates and prompts them to merge, which will make space available and make searching the phone book much more convenient. SIM-This step is mandatory for maintaining order.

Frequent problems and their solution

Sometimes users are faced with a situation where the delete button is inactive or contacts return after a reboot.This can be due to sync errors or locking by the carrier (although the latter is rare for normal entries).If you can not delete the number, check if it is not protected by administrator rights or corporate profile.

⚠️ Note: If contacts continue to appear after deleting, check your sync settings. They may be automatically downloaded from a backup of another device or from a messenger app (such as Viber or Telegram) that has access to the phone book.

It is also important to consider the physical condition. SIM-Old or damaged chips may not work properly, preventing the changes from being recorded, and the only solution is to replace them. SIM-cards with the operator with the number saved, after which the new card will be clean.

Another reason could be a failure in the Contacts app, and try to clear its cache through the app settings, and if that doesn't work, restarting your phone in Safe Mode can help determine if a third-party app is interfering with the phone book.
