Changing a smartphone or a sudden failure of the operating system often causes panic when important phone numbers are at risk. Device owners Xiaomi, Redmi and Poco often wonder how to quickly and safely transfer saved recordings from the phone memory to physical SIM card. This action guarantees the safety of data even if the gadget is completely lost or flashing is necessary.
The copying procedure in the shell MIUI or HyperOS has its own characteristics that differ from pure one Android. The standard mechanism of the system allows you to export data, but requires care in choosing the format and source. In this article, we will analyze all the steps in detail so that you can confidently manage your contact list.
It is important to understand that modern smartphones by default offer to store numbers in Google account, which is the most reliable synchronization method. However, the use of a SIM card remains in demand for compatibility with push-button phones or when selling a device to a new owner without transferring personal data.
Preparing for data transfer and checking the storage format
Before taking active steps, you need to make sure that your recordings are actually in the device’s memory and not already synchronized with the cloud or another account. Open the application Contact and pay attention to the top of the screen or the display settings menu. If you see a division into groups, for example, “Phone”,”SIM 1”,”Google”, then you have to work with the group "Phone" or "Device".
You should take into account the technical limitation: the SIM card has a very small amount of memory and a primitive file system. It is not intended to store additional information, such as photographs, email addresses, links to social networks or second numbers.
⚠️ Attention: When copied to a SIM card, all additional information (photos, addresses, notes) will be permanently deleted. Only the name and one main phone number will be saved.
To start the procedure, make sure that a SIM card with a sufficient number of free cells is installed in the slot. Old cards can hold up to 250 entries, new ones - up to 500, but it’s better not to take risks and not fill the storage to capacity. Also check that your Xiaomi has sufficient battery power, although the process is not energy-intensive.
If you have several accounts on your phone, the system may save new numbers there by default. For correct export, we need to work with the local device database. In some firmware versions, access to local storage may be hidden if synchronization is enabled.
Step-by-step guide: export via a standard application
The main transfer method is built directly into the system application MIUI. The algorithm of actions may differ slightly depending on the version of the shell, but the logic remains the same. First, launch the application Contact (icon with a silhouette of a person).
Next you need to get to the control menu. It is usually hidden behind the three dots in the upper right corner or behind the menu button. In the list that opens, look for the item "Settings" or immediately "Import/Export contacts."
☑️ Algorithm of actions
In the import/export menu you will see several options for actions. We are interested in the item Export to SIM card (or "Copy to SIM card"). The system may prompt you to select a source, if you have several accounts - select "Phone" or "Device".
After selecting the source, the system will ask you to confirm the action. Click OK or Yes. If there are many numbers, the process may take several seconds. Upon completion, you will see a notification about successful copying.
In some cases, if the entry contains several numbers, the system will ask which number needs to be copied, since the SIM card only supports one number per name. Select the main (mobile) number.
An alternative method through the system settings
If you cannot find the desired function through the app due to the interface features of your version MIUI, you can use the deep settings of the smartphone itself. This method works on most devices Xiaomi and Redmi.
Go to the main menu Settings (gear). Scroll down the list and find the section "Applications". In some firmware versions, this item may be called “All applications” or “Manage applications.”
In the list of installed apps, find the system application Contact (may have an icon of a handset or a person). Tap on it to open the app information page. Here we are interested in the button "Open" or direct transition to the import function, if it is included in shortcuts.
However, a more reliable path through the settings looks like this: Settings → System applications → Contact → Import/export contacts. This path is guaranteed to lead you to the desired menu, bypassing possible bugs in the main screen interface.
Here also select the option Export to SIM card. The system will warn you that some data may be lost (photos, email). Confirm your agreement.
What to do if there is no "Export to SIM" item?
If you do not see this item, perhaps there is no SIM card installed in the phone or it is not detected by the system. Check the SIM card status in the "SIM cards and mobile networks" settings. Also, the function may not be available if you are trying to export contacts from a Google account, and not from the phone’s memory.
Table: Comparison of methods for storing contacts
So that you can make an informed decision about whether to use a SIM card for permanent storage, we suggest comparing the main methods. Each of them has its own advantages and disadvantages depending on your goals.
| Characteristics | Phone memory | SIM card | Google Account |
|---|---|---|---|
| Memory capacity | Limited only by device memory | Very small (up to 500 records) | Almost unlimited |
| Saving photos | Yes | No | Yes |
| Add. fields (email, address) | Yes | No | Yes |
| Synchronization | Only on this device | Only physical transfer | Automatically on all devices |
| Security | Risk if the phone breaks down | High (does not depend on software) | High (if there is a password) |
The table shows that which Google Account is the most functional solution for everyday use. The SIM card acts more like an emergency medium or a tool for migration to devices that do not support smart functions.
Using phone memory is convenient if you do not want to be tied to the Internet, but it is risky. When resetting to factory settings (Hard Reset), all local data will be destroyed if it was not previously copied.
Possible problems and solutions
During the copying process, users may encounter various errors. The most common problem is a message that SIM card memory is full. This happens when the number of entries in the phone exceeds the number of free cells on the card.
In this case, you have two options: remove some of the old or unnecessary numbers from the SIM card or select the most important contacts for transfer manually. Mass export will be interrupted if you do not free up space.
Before bulk copying, remove old entries from the SIM card with the prefix "(1)","(2)", which may have remained from previous takes. This will free up space for current contacts.
Another common situation is “crooked” display of names. Due to encoding limitations of older SIM cards, Russian letters may appear as question marks or hieroglyphs. Unfortunately, it is impossible to fix this on the card itself; this is a technical limitation of the GSM standard.
An error may also occur if the contacts file is damaged or contains incorrect characters. In this case, try copying contacts in small groups to identify the problematic entry.
⚠️ Attention: The "Import/Export" menu interface may change depending on the MIUI version (12, 13, 14) or when switching to HyperOS. The location of the buttons may differ, but the essence of the functions remains the same.
Importing contacts from the SIM card back to the phone
After you have changed the phone or restored the system, the contacts must be returned from the SIM card to the smartphone’s memory so that they can be fully used. The process is almost identical to export, but the reverse action is selected.
Go to Settings → Contact → Import/export contacts. Now select item "Import from SIM card". The system will prompt you to select a destination folder: phone memory, Google account or another connected service (for example, MI Cloud).
It is recommended to immediately import data in Google account. This will automatically synchronize them with mail and protect them from loss in the future. Select the desired account from the list.
Confirm the import. The phone will read all the records from the card and create copies of them in the selected storage. After this, you can clear the SIM card again if you plan to sell the phone or. send it in for repairs.
Frequently asked questions (FAQ)
Will contacts be lost from the phone after copying to a SIM card?
No, they will not be lost. The “Export” or “Copy” operation creates a duplicate record. The originals remain in the phone’s memory until you delete them yourself. delete.
Is it possible to copy contacts from iPhone to SIM card via Xiaomi?
Direct transfer from iPhone to SIM card via the Android menu is not possible. The SIM card must first be inserted into the iPhone, the contacts must be copied to the iPhone's memory (Settings → Contacts → Import from SIM), and then exported from the iPhone to a Google account or vCard file, which is transferred to Xiaomi.
Why are the contacts on the SIM card displayed as "Contact 1", "Contact 2" without names?
This happens if Unicode encoding was not selected when saving to a SIM card from another device or if the card is very old and does not support long names in Cyrillic. When imported to Xiaomi, names can be restored if the metadata is saved correctly, but most often the names are lost forever when written to the card.
How to copy contacts if the phone screen is broken and does not work?
If the sensor does not work, but there is an image, you can try connecting a USB mouse via an OTG adapter. If the screen is completely black, but the phone is working, the only thing that will help is connecting to a computer and using apps to manage Android (for example, ADB), provided that USB debugging was previously allowed.
How many contacts can a SIM card hold?
The standard capacity of modern SIM cards is from 250 to 500 entries. The exact number depends on the operator and card type. Each entry occupies a different number of cells depending on the length of the name and number.
A SIM card is an excellent tool for emergency backup of base numbers, but to fully use all the capabilities of the smartphone, it is better to rely on Google cloud synchronization.
