How to delete a number from SIM-Xiaomi maps: The full guide

Changing mobile operators or switching to a new tariff often involves the need to transfer contacts. Owners of Xiaomi, Redmi and Poco smartphones often face a situation where after importing a phone book, old records remain on the chip, occupying limited space. SIM-The map is significantly inferior to the internal storage, and its overflow can lead to errors in saving new important data.

The cleaning procedure is not always obvious, as modern versions of the MIUI shell and HyperOS offer to save all data to the cloud or to the device by default. However, physical deletion of records from the chip is required regularly to maintain order. In this article, we will discuss all available ways to delete numbers, including hidden functions of the system application and third-party tools.

It is important to understand that deleting information from a SIM card is an irreversible process if you do not have a backup, so before you start any manipulations, you should make sure that all important contacts are already copied to Google Account or to the phone memory, which will avoid accidental loss of the necessary connections in the process of optimization of storage.

Preparation for cleaning and backup

Before we start radical cleanups, we need to do some preparatory work. Today's Xiaomi smartphones have powerful synchronization tools that you should use. The first step is to back up all contacts so that if you make a mistake, you can easily recover lost data, which is especially true if you plan to delete all records at once.

To create a backup, go to your phone’s settings and find the account section. Select your Google Account and make sure the contact sync slider is activated. You can also use Xiaomi’s built-in Security app, which allows you to create local copies of data.

⚠️ Note: Removing contact directly from SIM-The cards don't send them to the basket. They disappear instantly and irrevocably unless a pre-copy has been made.

Once you've saved the data successfully, you can move to directly managing the records on the chip, and it's worth noting that the menu interface may vary slightly depending on the version of MIUI, but the logic of the action remains the same for the entire ecosystem.

Delete via the standard Contacts app

The main tool for managing the phone book in Xiaomi devices is the regular Contacts app, which is where the feature that allows you to filter and delete entries stored specifically on the SIM card is hidden. First, open the application and pay attention to the top of the screen, where the current phone book usually appears.

Click on the active contact book name (often “All contacts” or account name) and select “Display Settings” from the drop-down menu or go straight to the filter «SIM-This action will hide all the other recordings, leaving only the ones that are physically on the chip on the screen.

Use of the import/export function

An alternative and often more reliable way is to use the import and export function, which allows you to first upload all the data from the chip to the internal storage, and then clear the SIM card in one action, which minimizes the risk of error and gives you full control over the process.

Management through system settings

In some versions of MIUI, access to managing SIM card contacts can be obtained through general system settings, bypassing the phone book application, which can be useful if the standard application does not start or does not work properly.

Why contact us SIM-The map has a length limit?
GSM standards that run on SIM cards are long-standing and have strict restrictions: Contact name is usually limited to 14-16 characters, and the number can only be written in an international format without additional characters, which is why names are often cropped when transferred to a phone.

Third-party applications for contact management

If Xiaomi’s built-in tools seem uncomfortable or don’t provide the right functionality, you can always turn to third-party developers. There are many applications specializing in managing the phone book on the Google Play store.

One popular solution is the SIM Manager app, or high-rated analogues, which allows you to view the contents of the chip in detail, edit records, change their order and, of course, delete unnecessary numbers in batch or one at a time.

When installing third-party software, be sure to pay attention to the permissions requested. Contacts and Phone will be required for the application to work with contacts; Be careful of applications that require access to SMS or location without obvious need.

Third-party apps are a great solution for batch processing, but always check the developer rating before installing to avoid passing your data on to third parties.

Typical problems and their solution

Users may encounter various difficulties in cleaning, often when the delete button is inactive or contacts are not displayed, this may be due to a software failure or physical damage to the chip.

One common problem is sticking the contacts, which even after being deleted can remain visually on the list until the device restarts, in which case it is enough to simply reboot the Xiaomi smartphone to update the phone book cache.

If the phone writes SIM Error or doesn't see the card when trying to write/delete, try removing the tray, wipe the SIM card contacts with soft dry cloth and insert it back in. Make sure the chip is installed correctly and sits tightly in the slot.

Also, check if sync with another account is enabled in the background, which can instantly return deleted numbers.

What if the contacts are deleted but then reappear?
