Owners of the popular smartphone Xiaomi Mi A1 Often faced with the need to transfer the accumulated phone book to a new one. SIM-This may be due to a change of operator, a change of device, or a simple desire to create a physical backup of important numbers. Despite the fact that modern Android systems prefer cloud storage, the ability to export data directly to the card chip remains relevant for many users.
The number-saving procedure does not require the installation of third-party software, as the operating system's built-in tools allow this task to be completed in a few steps: SIM-The card has limited memory and supports only basic text data, ignoring avatars and additional numbers.
In this article, we will discuss in detail the algorithm of actions that will help you safely and quickly move records from the internal memory of the device to the map. We will look at the nuances of the Android One interface installed on the Xiaomi Mi A1, and answer frequent questions that arise in the process.
Features of storing contacts in Android One
Xiaomi Mi A1 is powered by a pure Android operating system known as Android One. Unlike MIUI shells, it uses Google’s standard Contacts app, which has its own synchronization features. By default, all new entries are saved to a Google account, which ensures that they are instantly restored when you change device.
However, the physical copying of SIM-The map requires manual intervention through the control menu, and it is important to note that exporting can be shortened long names and remove extra fields such as email or address, so it is recommended to back up in the cloud before mass migration of data.
⚠️ Attention: SIM-The card does not support the preservation of numbers starting with a plus (+), In some older recording formats, make sure the dialing format meets your carrier's standards.
Understanding the structure of the storage avoids confusion when some contacts “disappear” or are displayed incorrectly after transfer, the system separates data sources, and each of them has a separate functionality in the settings menu.

The internal memory of the phone allows you to store full profiles, while SIM-The card is limited to the name and primary number only.
Preparation for the data transfer procedure
Before proceeding with active actions to move records, you need to make sure that SIM-The card is correctly installed and determined by the system. insert the chip into the corresponding Xiaomi Mi slot A1 And wait for the network signal to show up, and if the card is new, it may require that it be sent to the network. PIN-first-induction code.
It's also worth checking if the SIM card itself is full, because older SIMs can hold as little as 250 records, whereas modern standards allow you to store up to 500 or more contacts, and if you're planning to move the entire phone book, make sure there's enough space.
- 📱 Make sure that SIM-The card is active and visible in the system.
- 🔋 Charge the smartphone battery to at least 30-40% avoiding accidental shutdown.
- ☁️ Check for the latest version of the Contact App in the Play Market.
- 📝 Write down critical numbers manually on paper in case of a crash.
Another important step is to clean up duplicates, often accumulating repeated entries in the phone book that will take up extra space when transferred, and the built-in Android tools allow you to combine duplicates, which optimizes the export process.
☑️ Ready for transfer
Step-by-step: export through the Contacts app
The main method of transfer is through the regular call management application. The interface of Xiaomi Mi A1 is minimal, so all the necessary functions are in logical places on the menu. Open the Contacts app on the home screen or in the application menu.
In the upper right corner or in the side menu (depending on the update version), find a three-dot icon or gear. When you click on it, you will see a drop-down menu where you need to select Settings or Contact Management. This is where import and export functions are hidden.
Menu → Settings → Contact Management → Import / ExportIn the window that opens, select the option "Export to" SIM-The system will suggest you select a data source. If you have multiple accounts or local storage, specify a "Phone" or a specific Google account where you want to copy the data. Once confirmed, the copying process will begin.
⚠️ Note: Do not remove during mass copying SIM-card and do not restart your smartphone, as this may damage the contact file system.
It can take anywhere from a few seconds to a couple of minutes, depending on the number of records, and when you complete the process, you will receive a notification that you have successfully completed the operation, and now your numbers are available on a physical card and can be used on other devices.
Alternative ways to copy numbers
If the standard path is not available or not working properly, there are workarounds, one of which is using the vCard file. You can export all contacts to one file to internal memory and then, using the file manager, find that file and open it by selecting the target device. SIM-map.
Another option is to use third-party apps from Google Play that specialize in managing the phone book, programs like Copy My Data or SIM Card Manager, which often have more flexible settings and allow you to selectively transfer records by filtering them into groups.
Connecting Xiaomi Mi A1 over USB allows you to copy the database of contacts (requires access to system files or use of ADB), convert it and write it to SIM through a special card reader, although this is extremely rarely used in everyday life.

Table of constraints and possibilities of formats
When transferring data, it is important to consider the technical differences between the internal storage of a smartphone and the SIM card chip. Below is a comparative table showing which data is saved and which will be lost during migration.
| Type of data | Phone memory | SIM-map | Google account |
|---|---|---|---|
| Name of contact | Complete. | Up to 14 characters | Complete. |
| Phone number | A few. | One of the main | A few. |
| Photo Credit | There is. | No. | There is. |
| Email/Address | There is. | No. | There is. |
As you can see from the table, SIM-The card can only store a name and a single phone number, and the length of the name is strictly limited. All additional fields, such as company, position, notes and rhythn-ton, will be irretrievably lost when exported to the card.
That is why this method is recommended to be used only as a temporary solution or for transfer to button phones. For a full backup, it is much more efficient to use synchronization with Google or uploading a file to an external drive.
Addressing export challenges
Xiaomi Mi users A1 This may be the case when the item "Export to" SIM-The card is inactive or hidden, most often because the phone is not defined. SIM-card or PIN-code that the system cannot request at the time of accessing the function.
Another common problem is the memory error. SIM-In this case, the system will suggest selecting contacts to copy, you will have to manually mark the numbers that are really needed, or pre-clean the map of old records through the control menu. SIM.
- 🔄 Restart the device if the contact settings menu does not open.
- 🗑️ Remove old unnecessary numbers from SIM-Cards before new importation.
- 🔓 Unlock. SIM-card, if it's protected PIN-code.
- 📵 Check if the flight mode is on (it should be off).
If none of the methods work, the problem may be with the chip itself. SIM-Some operators issue cards with reduced functionality or damaged memory, in which case you should contact the communication salon to replace the SIM card with a number.
💡
If there are too many contacts, copy them in parts of 50-100 pieces to avoid freezing the interface and data loss in case of failure.
Import contacts back to the phone
After you have used it, SIM-If you have a card in another device or decide to return the data back, you will need an import procedure. A1 It's done symmetrically with exports. Go to your contact settings and select "Import with" SIM-map".
The system will ask where to save data: in memory of the phone, in the account Google or other connected service, it is recommended to choose Google, as this will provide automatic synchronization and protection from loss when the device breaks.
During the import process, you may request permission for applications to access contacts. Be sure to confirm this action, otherwise the copy will be interrupted. Once completed, check the phone book for duplicates and combine them if necessary.
