Managing the phone book on Xiaomi smartphones is often a daunting task, especially when the device begins to warn of memory overflow.Many users are unaware that numbers can be stored not only in the phone's memory or Google account, but directly on the chip. SIM-It is this hidden data layer that often causes duplicate records and the inability to add new contacts, even if the device's internal memory is empty.
In this article, we will discuss in detail how to find and remove contacts with the SIM-You'll learn to distinguish between number storage sources, clear SIM memory and, most importantly, transfer important data to the cloud so you don't lose it when you change devices. Understanding storage structure is key to order in your phone directory.
The cleaning process may seem confusing because of the features of the MIUI shell or HyperOS, but the algorithm of actions is the same for all modern models. We will consider the regular tools of the system that do not require the installation of third-party software. The safety of your data is a priority, so before any manipulations, you should make sure that important numbers are copied to the account.
Differences between phone memory and SIM-map
Before you start deleting, you need to clearly understand where the information is physically stored. SIM-Cards are an outdated but still used storage standard that has strict limitations. Unlike modern smartphone memory, a SIM can only store basic data: name and number, often with a limit on the number of characters in a name.
When you see notifications that “contact memory is full,” it almost always refers to the limits. SIM-Xiaomi smartphones by default tend to save all new records in internal memory or sync them with Google Contacts, but when imported from old devices or manually selecting the location of saving numbers can get on the SIM.
- 📱 Limited capacity: SIM card can accommodate 250 to 500 numbers, while the phone memory is limited to only gigabytes of free space.
- 🔒 Data security: If you lose or break your phone, the contacts on the SIM are saved, but if you lose the SIM, you lose all the numbers if they are not duplicated.
- 🔄 Synchronization: Contacts in the phone’s memory are synchronized with the cloud, and records on the phone’s memory are synchronized SIM-The map is static and not updated remotely.
It is important to note that modern Android operating systems, including shells from Xiaomi, are gradually moving away from writing data directly to the SIM card, which is done to improve security and usability, but the ability to read and manage this data remains available to ensure compatibility with older devices.
⚠️ Note: Removing contact directly from SIM-Unlike a cloud account where deleted files are stored for 30 days, a SIM card does not have a clipboard.
Preparation for cleaning and backup
You should only start working with the phone book after you have backed up, and even if your goal is to delete it, you run the risk of accidentally erasing the number you want because of interface confusion or random clicking, and backup is a simple procedure that takes less than a minute.
The most reliable way to save data on Xiaomi is to use the built-in export function to the.vcf file or sync with the Google account. The file can be saved to internal memory or sent to yourself by email, which will create a restore point that can be returned to at any time.
☑️ Pre-deletion check
To back up, go to Contacts, click three dots in the corner of the screen, and select Import/Export Contacts. Select Export to Memory. The system will create a file that will contain all your current records, including those on the SIM card.
If you plan to move numbers, make sure you have a stable Internet connection to sync with Google, which will automatically save all changes to the cloud, and your account settings should tick the “Contact” box.
Step-by-step: removal through the Contacts app
The basic method of managing records on SIM-The map in the Xiaomi smartphones is carried out through the regular application "Contacts". the interface may vary slightly depending on the version. MIUI, But the logic is the same. You have to switch the list display to only see the SIM card records.
Open the Contacts app and find the display settings menu, which is usually hidden under a three-dot icon or filter icon. Select Contacts to Display or Contact Filter. In the source list that opens, leave a tick just opposite yours. SIM-maps, for example,"SIM 1" or"SIM 2").
Now, the screen only displays the numbers that are physically written on the chip. To remove one contact, click on it, select three dots in the upper right corner and click "Delete." If you want to clear everything at once, use the mass selection function.
Sequence of action:
1. Contacts → Menu (three dots) → Display settings
2. Select only the SIM-card
3. Long press on any contact
4. Select "All" (or select the necessary)
5. Click "Delete" → Confirm the actionOnce confirmed, the system will request final permission to delete, and be careful: at this point, the data will disappear forever. If you have not previously made a backup, you can only restore the numbers through a special operator or leaving hope that the number is saved in the cache of an application.
What to do if the filter menu is not found?
Remove through Xiaomi system settings
If you can't find the settings you want through the Contacts app, you can use Xiaomi's deep system settings menu, which is more reliable because it addresses the contact store directly, bypassing the application interface.
Go to the general Settings smartphone, scroll down to the Apps section and select App Management. In the list, find the Contacts app (don't confuse it with Phone or Contacts). SIM-If the cards are handed out separately, look for the item "Storage" or "Memory" within the app menu".
Here you will see the "Clear" or "Contact Management SIM" button. Pressing this button will open the system window for managing SIM card records, which is especially useful if the "Contacts" application is not working correctly or freezes when you try filtering.
| Access method | Difficulty | Risk of error | Availability |
|---|---|---|---|
| Through the Contacts app | Low. | Medium. | All models. |
| Through phone settings | Medium | Low. | MIUI 12+ |
| Through import/export | Tall. | High-pitched | All models. |
Using system settings gives you more access, but it requires care. Make sure you clean it. SIM-a card, not an app memory, although in the context of contact management SIM These concepts often overlap in the interface.
⚠️ Note: When cleaning the data of the "Contacts" application through the system settings, not only the numbers from the SIM can be deleted, but also local display settings and call history, unless a specific subsection is selected. SIM.
Transferring contacts to your Google account
Instead of simply removing the contact with SIM-It's much smarter to transfer these cards to your Google account, and that's going to solve the space problem, and it's going to keep the data safe.
In the Contacts app, select the menu (three dots) and click Import/Export Contacts. Select the Import with option. SIM-The system will prompt you to select your destination – specify your Google account (usually signed by your mail) or “Device” if sync is enabled.
Once you have completed importing, you have duplicates: some numbers will remain on the SIM, others will appear in the cloud. To avoid confusion, go back to the deletion instructions and clear the SIM card, since the copy in the cloud has already been created. This is the standard data migration procedure.
- ☁️ Auto Sync: New contacts will be immediately saved in the cloud, freeing up space on the SIM.
- 🔍 Search and Sort: Google Contacts offers smart search, take-ups, and computer editing.
- 📲 Availability: If you lose your phone, it is enough to enter a login and password on a new device to restore the entire book.
Google porting also allows you to add photos, extra numbers, email addresses and birthdays to your contacts, which is technically impossible to implement in a limited storage format. SIM-map.
💡
Moving contacts to Google isn’t just about cleaning up a place, it’s about moving to a modern data security standard where your numbers aren’t tied to a plastic card.
Solution: duplicates and synchronization errors
Often, after the deletion or transfer procedure, users are faced with the problem of duplication of records, which occurs when the phone displays both a local copy and a copy from the SIM card simultaneously, and to fix this, you need to configure the display filter.
In Contacts, click on the filter icon (usually looks like a funnel or three bars). Select the option to Combine Duplicates or manually set up the display by ticking only on your Google account. This will hide the SIM card entries from the shared list, even if you haven't physically deleted them.
Another common mistake is to say "Not enough memory" when trying to save a new number, even after deleting it, which could mean that the phone is still trying to record the contact on the phone. SIM-Check the default saving settings.
Go to Settings → Apps → Contacts → Settings. Find Preferred Save Place or the same and select Phone or Google Account to prevent future overflow issues.
⚠️ Note: If contacts reappear after deletion when rebooted, sync with another account or app (such as Mi Cloud or WhatsApp) that recovers deleted records may be enabled.
