Owners of Xiaomi smartphones are often faced with the need to free up space on the SIM card or put the list of subscribers in order. Despite the fact that modern devices have huge internal memory, many users, out of habit, save important numbers on the operator chip. This creates limitations, since the capacity SIM usually does not exceed 250 contacts, and the editing functionality on the media itself is extremely poor.
The cleaning process may be required when changing operators, moving, or simply to delete old, irrelevant records that occupy precious cells. In the ecosystem MIUI and new shells HyperOS tools for working with the phone book are built deep into the system, but are accessible through the standard Contacts application. Proper organization of this process will help avoid data loss and speed up the operation of the device.
Next we will analyze in detail all the ways to manage the list of subscribers stored on the chip, from manual deletion to mass transfer to the cloud. You will learn to distinguish between types of memory and understand why storing numbers directly on SIM card is considered an outdated approach in the era of cloud technologies.
Why it is important to transfer contacts from SIM to phone
Storing data directly on the communication module has a number of critical disadvantages, about which are often forgotten by users. The main limitation is the amount of memory. A standard USIM card holds a limited number of records, and if you try to save more data, the system will simply throw an error. In addition, the chip usually stores only a name and one phone number, without the ability to add an email, address or photo.
If lost or damaged SIM cards all data stored on it will be lost forever. Unlike a Google account, where information is synchronized instantly, physical media does not have a backup copy. If you often change operators or card formats (for example, from Mini to Nano), the risk of losing information increases many times over.
⚠️ Attention: The SIM card is not intended for long-term storage of large databases. If contacts are frequently written and deleted, a logical failure of the chip's memory sector may occur, which will make some cells unavailable for writing. Modern smartphones offer integration with the cloud and the cloud. This allows you not only to store an unlimited number of records, but also to restore deleted numbers within 30 days. Transferring data to phone memory or the cloud provides access to advanced search functions, grouping and automatic spam detection.
Modern smartphones Xiaomi offer integration with Google Contacts and cloud Mi Cloud. This allows you not only to store an unlimited number of records, but also to restore deleted numbers within 30 days. Transferring data to phone memory or the cloud provides access to advanced search functions, grouping and automatic spam detection.
Before starting any cleaning operations, be sure to back up your contacts in your Google Account. This will take a couple of minutes, but will save your data in case of an error.
Preparing for cleaning and checking the storage type
Before you begin deleting, you need to determine exactly where your numbers are stored. The phone can have several sources of contacts: the device’s local memory, a Google account, a Xiaomi account, and itself SIM. Mixing these sources in one list often leads to confusion and duplicates.
First, open the standard application Contact on your smartphone. At the top of the screen or in the side menu (depending on the version MIUI), find the display filter. Make sure that the view all contacts mode is selected to see the full picture of what is loaded in the phone book.
Now you need to filter only those entries that are on the chip. Go to the application settings through the three dots in the corner of the screen and select Display contacts. Here you will see a list of all available storages. Uncheck all items except SIM cards. Now only those subscribers who are recorded directly on the communication module will remain on the screen.
☑️ Check before cleaning
A visual assessment of the list will help you understand the scale of the work. If you see many entries with the same names or outdated numbers, this is a clear signal to take action. It is also worth checking whether important work numbers are stored on the SIM card, which must first be rewritten to another location.
Manually deleting contacts directly from the SIM card
The easiest way to free up space is to manually delete unnecessary entries. This method is suitable if you need to remove just a few numbers or remove specific erroneous entries. The process is intuitive, but requires care so as not to erase the necessary information.
Open the contact that is to be deleted. Click on the edit button (usually a pencil icon). In the action menu, select Delete. The system will ask you to confirm the operation. It is important to keep track of exactly where the entry is being deleted: the deletion message should indicate “from SIM card.”
If you have an older version of the shell installed, the interface may be slightly different. In such cases, deletion is often done by long pressing on the contact's name in the general list. A context menu will appear where you need to select delete. Make sure that you are not in the mode of editing a contact saved in the phone's memory, otherwise you will delete the wrong entry.
⚠️ Attention: The process of deleting from the SIM card is irreversible at the level of the chip itself. If you accidentally deleted an important number and did not have a copy of it in the cloud or on paper, it will be impossible to recover it using software.
To speed up the process, you can use the multiple selection mode, if it is available in your firmware version. A long press on the first contact activates the selection mode, after which you can tick several entries in a row and delete them with one button. This significantly saves time when cleaning a large list.
Bulk management and transfer of data to the cloud
To completely clear a SIM card, the most effective method is a mass transfer of all data to a more reliable storage followed by formatting the chip memory. This allows you not to lose a single number and immediately optimize the database.
In the application Contact go to the settings menu (three dots). Find the section Import/Export contacts. Select option Import from SIM card. The system will prompt you to select a destination: save contacts to your account Google or to your phone memory. Confirm the selection of all numbers for transfer.
After successful copying, return to settings and select the option Delete contacts from the SIM card. This feature is not available in all versions MIUI directly, so sometimes you have to remove them manually after migration using the method described in the previous section. However, if the option is available, it will clear the chip in a few seconds.
What to do if the import button is inactive?
If the system does not see the contacts on the SIM card, try removing it and inserting it again. Also check if access to contacts for the Phone application is disabled in the permissions settings.
After the transfer, be sure to check the synchronization. Go to your phone settings, section Accounts and synchronization, select your Google account and click "Synchronize". Make sure the checkbox next to "Contacts" is active. Now your data is protected by Google servers and accessible from any device.
| Characteristics | SIM card | Google Account | Memory phone |
|---|---|---|---|
| Record limit | ~250 contacts | No restrictions | Depends on location |
| Additional. fields (email, photo) | No | Yes | Yes |
| Risk of loss when changing SIM | High | Absent | Average |
| Deleted data recovery | Impossible | Up to 30 days | Only from backup |
Eliminating duplicates and merging records
A common problem when working with contacts is the presence of duplicates. This happens when the same number is stored on the SIM card, in the phone memory, or in different accounts. Xiaomi provides a built-in tool to solve this problem, which greatly simplifies the user’s life.
In the Contacts application, find the section Manage contacts or Organize contacts. Select item Merge duplicates. The system will automatically scan the database and find records with the same names or phone numbers. You will be asked to confirm the merge or do it automatically for all found pairs.
This function is especially useful after importing data from SIM. Migration often creates copies if the original already existed in the cloud. The merge tool compares not only names, but also numbers, ignoring formatting (brackets, dashes, country code), which makes it very efficient.
⚠️ Attention: When automatically merging, check the result carefully if you have contacts with the same names but different numbers (for example, “Ivan Work” and “Ivan Dom”). The system may mistakenly combine them into one card.
Manual editing is also available for complex cases. You can open a contact card and see the Related Contacts section. Here you can manually add a link to another record or, conversely, break the link if the merger occurred by mistake. This gives you complete control over the structure of your phone book.
Display settings and list sorting
After cleaning and transferring the data, it is important to configure the convenient display of the list. The chaotic order of names makes it difficult to find the right subscriber. In the application settings Contact you can select your preferred sorting order: by first name or last name.
For Russian-speaking users, the “First Name Last Name” order is most often convenient, while in Western practice “Last Name First Name” is accepted. Changing this setting instantly rebuilds the entire list. You can also customize the display of names: show only the first name or the full name with the middle name, if it is written down.
Another useful feature is setting the visibility of contacts without a number. Sometimes the database contains empty records or business cards of companies without a direct contact number. In the section Contact filter you can check the box "Hide contacts without a number" to clear the visual noise in the list.
Correctly setting up sorting and filtering saves time searching for a number in emergency situations and makes the application interface cleaner and clearer.
Don't forget about the "Favorites" function. Contacts you add to your favorites appear in a separate tab or at the top of the list, giving you quick access to the people who matter most. This does not affect data storage, but significantly improves the user experience.
Frequently asked questions about managing contacts on Xiaomi
Is it possible to restore contacts deleted from a SIM card?
Unfortunately, it is impossible to restore data deleted directly from the SIM card chip using standard means. The SIM card memory does not have a recycle bin. The only chance is if you had synchronization with the account before deletion, or if you backed up the contacts file (.vcf) to a memory card or to the cloud.
Why are contacts displayed twice after the transfer?
This happens if the display setting includes several sources at the same time. For example, you see the original on SIM and a copy on Google. Go to the display settings and leave a checkmark next to your Google account only. Duplicates can be eliminated using the merging function.
How to transfer contacts to a new Xiaomi phone?
The easiest way is to log into the same Google account on the new device and enable synchronization. All contacts will be pulled up automatically. You can also use the "Mi Mover" application to quickly transfer all data from your old phone to a new one via Wi-Fi.
Does the number of contacts affect the speed of the phone?
Modern smartphones Xiaomi can easily handle thousands of contacts. However, if you store them on a SIM card, access to them may be slower and functionality limited. Storage in the cloud or internal memory does not have a noticeable effect on system performance.
What to do if the phone does not see the SIM card?
Try to restart the device. If this does not help, remove the tray, wipe the SIM card contacts with a soft cloth and insert it back, maintaining the correct position. Check to see if the chip itself is damaged. If the problem persists, the slot may be faulty or the card needs to be replaced by the operator.
