Changing a mobile device or switching to another operating system often causes stress associated with the risk of losing important data. Among all the information stored in a smartphone, it is the phone book that is critical for most users. Contacts on Xiaomi are stored by default in the internal memory of the device or in Google cloud storage, which provides convenience, but creates vulnerability in the absence of access to the network or account.
That is why the question of how to copy contacts to the SIM card remains one of the most relevant requests in technical support. Transferring data to a physical medium allows you to quickly restore communication even in the event of complete loss or breakdown of the gadget. Android provides built-in tools for managing the phone book, but in the MIUI shell these functions can be hidden or called differently than in “pure” Android.
In this guide, we will analyze in detail all possible ways to save numbers, consider the nuances of working with different formats. SIM-You'll learn not only about the standard method through the settings, but also how to properly prepare the list for export so that no character is lost when you transfer it.
Preparation of the telephone book for transfer
Before you start copying, you need to make sure your data is in the right place. Often users do not even suspect that new numbers are not written in the memory of the phone, but directly to your Google or Mi Cloud account. To check this, open the Contacts app and pay attention to the top of the list or display settings. The source of saving must be clearly defined, otherwise the import operation may not be successful.
If you plan to move the entire database, make sure it's not scattered across multiple sources, and ideally, all records should be combined into a single list inside the memory of the device or account from which the export will be made, which will simplify the process and eliminate the duplication of records that often occurs when chaotic storage.
- 📱 Open the Contacts app on the home screen or in the Tools folder».
- 👤 Click on the three dots in the top corner to access the control menu.
- 🔍 Select Settings or Contact Management to check sources.
Particular attention should be paid to records containing more than one number or additional fields, such as an email or address. SIM-Some of this information may be lost because the chip's capacity is limited to only a name and one primary number. GSM Supports storage of a name up to 14 characters long and numbers up to 20 digits long, so long names will be cropped.
💡
Before mass copying, it is recommended to make a full backup through Mi Cloud or Google Contacts to have a rollback point in the event of a crash.
Step-by-step instructions for copying through settings
The most reliable and regular way to move data is to use the built-in functionality of the MIUI shell. This method does not require the installation of third-party applications and ensures the correct operation of the system. First, you need to go to the contact management menu, which is located in the depth of the system settings.
Click on the gear icon in the Contacts app or find the corresponding section in the general settings of your smartphone. Here you are interested in the item related to import and export of data. Depending on the firmware version, it can be called “Import Contacts” or “Export to the Internet”. SIM-map».
☑️ Algorithm of action
Once you have selected a source (inner memory or Google account), the system will prompt you to tag records, you can select individual numbers or use the "Select All" feature, and be prepared for the fact that the process can take some time if you have hundreds of records in your database.
⚠️ Note: Do not remove during the copying process SIM-card and do not turn off the smartphone screen, so as not to interrupt the recording of data on the chip.
When you confirm the action, the system will start recording sequentially, unlike cloud synchronization, here the data is physically transferred to the card chip, and when you complete the operation, you will see a notification that the operation has been successfully completed.
Working with several SIM-map
Xiaomi and Redmi smartphones are traditionally equipped with two slots for SIM-The user must clearly understand which media is being copied to avoid confusion in the future. In the export menu, the system always asks for a choice of target. SIM-map.
If you're moving contacts to another phone, make sure you pick the card you're planning to retrieve. Copying on a second, backup SIM doesn't make sense unless you're planning to swap them. The logic here is simple: where you write it down, you can count it from there.
| Parameter | SIM 1 | SIM 2 |
|---|---|---|
| Principal appointment | Calls and the Internet | Reserve or number two |
| Memory capacity | 250 records | 250 records |
| Speed of access | Instant. | Instant. |
| Compatibility | All phones. | All phones. |
It is important to note that some of the older models SIM-If you try to copy 500 contacts to a card that has 250, the system will either stop the process or tell you which records to move.
Alternative methods and third-party applications
In situations where the standard menu is not available or not functioning properly, alternative ways of solving the problem can be used. Often users search for third-party applications on Google Play, but this is rarely necessary because the functionality of Android allows you to solve the problem by system means.
One effective, but less obvious way is to use the Share feature, where you can highlight all contacts, select the Share option, and send a business card file (.vcf) to yourself via messenger or email, and then, by opening this file on any device, you can import it directly to SIM through the standard tools of the new system.
- 📂 Allocate all contacts in the list with a long press.
- 📤 Click the “Share” button or send icon.
- 💾 Save the.vcf file to the device memory or send it to an email.
There are also specialized applications-managers who can work directly with memory. SIM-But using these cards requires the issuance of advanced permissions, which can compromise data security.
⚠️ Note: Third-party apps may request access to your personal data and messages. read permissions carefully before installing.
Another option is to use a computer. USB and by turning on the debugging mode, you can unload the contact base through ADB-commands, edit it and download it back, but it's a method for power users.
Possible problems and ways to solve them
Users may encounter various technical difficulties in the process of transferring data, most often the problem is format incompatibility or memory overflow. If the Copy button is inactive or the process ends in an error, first check the free space on the SIM card.
Another common situation is the encoding of names: contacts recorded in Cyrillic on some older phones may appear as a set of incomprehensible characters, which is because the GSM standard did not support Russian letters in the first place, and requires Unicode support from the receiving device to display them correctly.
Why aren't the contacts copied?
If you see a recording error message, try clearing the Contacts and Contact Storage app cache through the app's settings. This won't delete your numbers, but will fix possible software failures in the database.
In rare cases, the problem may be physical: contact SIM-If the card is oxidized or damaged, wipe the chip with a soft dry cloth and try again.
Synchronization with the cloud as a modern alternative
In the era of cloud technology, SIM-only contact storage is an archaic, if reliable, method. Xiaomi’s modern smartphones offer powerful synchronization tools through Mi Account and Google, which allows you to save not only your number and name, but also photos, addresses, birthdays and notes.
Using the cloud eliminates the need for manual copying every time you change your phone, simply logging in to your account on a new device, and the entire phone book will be restored automatically, and backing up to the cloud is done in the background and does not require user intervention.
However, you should have a local copy of SIM-If the cloud service is unavailable or the account is blocked, the physical medium will remain the only way to quickly restore communication. SIM — This is the most sensible strategy.
💡
The best data security strategy is to synchronize with the Google/Mi Cloud combined with periodic manual copying of important numbers on the SIM-map.
