Owning an Android device, especially from the popular Xiaomi brand, often challenges users to transfer personal data. SIM-card, especially when changing the device or resetting to factory. POCO face up to the features of the shell MIUI HyperOS, which may differ from the standard Android interface.
The need to keep numbers often arises spontaneously when an old phone starts to work incorrectly or a new gadget has already been purchased. SIM-The card has a limited amount of memory and can only store basic information: name and number, and all additional fields, such as photos, email addresses or birthdays, will be lost when exported. That is why before starting any manipulations, it is worth weighing all the risks and considering alternative ways of backing up.
In this article, we will take a look at all the available methods for saving your address book, we will look at the regular system tools, work with Google and Mi Cloud services, and the use of third-party applications, you will learn how to avoid common mistakes and ensure that important connections are safe.
Limitations and features of storing contacts on SIM
Before you start transferring, it is important to be aware of the technical limitations of the communication chip. GSM-The cards have a very limited amount of memory, which usually ranges from 250 to 500 records depending on the year of issue and operator. If your phone book is larger, the system will prompt you to copy only a part of the records, which can lead to the loss of important numbers without the possibility of recovery.
Another critical aspect is the storage format, unlike the internal memory of a smartphone or a cloud account, SIM-The card does not fully support Unicode, which can cause problems with displaying Cyrillic names or special characters. After transferring, the names can turn into a set of unreadable characters or be cropped to a certain length.
β οΈ Note: When copying the SIM-All additional contact fields (photo, address, notes) are permanently deleted!
Itβs also worth considering that modern Xiaomi smartphones offer default sync with a Google account.This is a more reliable way, since it doesnβt tie you to a physical medium. However, if your new phone doesnβt have internet access or you use a push-button machine, SIM porting is the only quick option.
Users often confuse "save" and "import" -- saving to SIM is done manually for each new number, unless you specify otherwise in the settings -- while importing is a mass action that we'll look at next, and understanding the difference between these processes will help you better manage your digital archive.
Preparation of the device and compatibility check
Before starting the procedure, make sure that SIM-The card is correctly defined by the system and installed in the correct slot. In two-symbol devices Xiaomi sometimes conflicts arise if the card is inserted in the wrong connector, which is chosen by default for working with data. β The phone. β General information showing the status of both cards.
Make sure there's enough space on the map. You don't have to move all the contacts at once, you can start with a test group. If you're planning to move hundreds of numbers, you'd better break it down into several steps, so you don't have to freeze the interface and lose data in the event of a crash.
An important step is to check the default format of the contacts' storage. Go to the Contacts app, click three dots in the corner and select Settings. In the Save Place, you should select Phone or Google account, but not Google account. SIM-If you don't want to save new numbers to the chip, it'll prevent future confusion.
βοΈ Pre-transfer check
It's not superfluous to make a full backup of your phone through the Mi Cloud or your computer, and even if you're confident in your actions, the human factor hasn't been reversed, and accidentally pressing the wrong button can cause the entire phone book to be deleted, and it won't be possible to restore it without a backup.
Export contacts from phone memory to SIM-map
The most common scenario is to transfer an existing database of numbers from the internal memory of the smartphone to the chip. In the MIUI shell, this process is implemented quite conveniently, although hidden in the submenu. Open the standard Contacts app and find the menu icon (three horizontal dots or stripes), usually located in the upper right or lower corner of the screen.
In the menu that opens, select "Import/Export contacts" and the system will offer several options. SIM-When you select this action, the phone will automatically analyze the list of contacts and determine which ones can be transferred and which contain data that is incompatible with the format. SIM.
Path to menu: Contacts β Menu (three dots) β Import/Export β Export to SIM- cardAfter selecting the target SIM-If you have two cards, the system will request confirmation of the operation. If you click OK, you start the copying process. Depending on the number of records, it can take anywhere from a few seconds to a couple of minutes.
β οΈ Note: If the system says that some contacts cannot be copied due to format incompatibility, do not ignore this.
After completion of the procedure, it is recommended to remove SIM-The card and check it on another device, preferably a simple button phone, to make sure the numbers are read correctly and not damaged. If it's a success, you can be sure of your data when you change your device.

Import contacts from SIM-cards in the memory of the smartphone
The reverse situation is when you need to move the numbers from SIM-This is standard procedure for the first launch of a smartphone. Once the card is installed and the phone is turned on, the system often suggests importing contacts. If no automatic offer is made, then manually act.
Go to the Contacts app and select the Contacts/Imports menu again. This time we are interested in the Imports with SIM-The system will show you a list of available contacts on the chip, so you can select individual records or click "Select all" for mass transfer.
The key here is choosing a destination, and the system will ask where to store the imported data: in memory of the phone, in Google account or other data. SIM-It is strongly recommended to choose a Google account or phone memory, which will ensure the safety of data and the ability to synchronize them.
| Parameter | Phone memory | Google account | SIM-map |
|---|---|---|---|
| Limit of records | Depends on free memory. | Up to 25,000 contacts | 250-500 contacts |
| Additional fields (photo, email) | Supported | Supported | Not supported. |
| Synchronization | Only on this device. | Automatic on all devices | Absent. |
| Risk of loss | High when broken. | Minimum | Medium (physical wear and tear) |
Once you've selected a save location, confirm the action. Contacts will appear on the list almost instantly. They're now editable, you can add photos to them and you can attach messengers to them, which turns a simple list of numbers into a full-fledged digital business card.

Import your contacts directly into your Google account, not your phoneβs memory, and this will allow you to access numbers even if your phone is lost or broken β just log in from any other device.
Working with VCF backup files
The most flexible and reliable way to transfer contacts is to use.vcf (vCard) files. SIM-The card allows you to transfer full contact information, including a photo and several numbers. The file can be transferred via Bluetooth, Mi Drop, email or saved to a cloud drive.
To create such a file, select Export to Device Memory or Export to Storage from the Import/Export menu. The system will create a file, commonly called contacts.vcf or 00001.vcf, in the root folder or MIUI folder. This file can be copied to your computer or sent to your messenger.
To restore contacts on a new device, it is enough to simply open this file. Xiaomi smartphone automatically recognizes the format and prompts you to import data. You can choose which account or memory section will be added to the number, which is ideal for migrating from an iPhone or other Android smartphones.
β οΈ Note:.vcf files may contain personal data, do not send them to public chats or store them on public resources without encryption or password.
The advantage of VCF is that it's versatile, you can build up a base over the years, save it once, and make sure that when you move to any other platform (whether it's Samsung, Huawei, or the new Xiaomi), you can quickly deploy your contact list, which is especially true for business users.
Sync with your Mi and Google account
Modern ecosystems offer automatic synchronization that makes manual copying of the SIM-Google account is integrated into the Android system by default. Just add the account in the Settings section β Accounts and synchronization and enable the slider "Contacts".
Any changes made to the phone book will be instantly reflected in the cloud. If you lose your phone or buy a new Redmi or POCO model, just type in your Google login and password and all numbers will go back to their places. Similarly, Mi Cloud, which often offers more free space for brand users.
Using cloud sync, you can not only save numbers, but also manage them from your computer. You can edit contacts, delete duplicates and sort them through the Google Contacts web interface, which is much more convenient than typing on a small smartphone screen.

Cloud synchronization is the gold standard for data retention, eliminating the need to think about physical media and ensuring that information is safe in any situation.
However, if you prefer to store data locally or you don't have consistent access to the Internet, a combination of methods (cloud + periodic export to VCF) is the best solution. Don't rely on just one way to protect information. Data duplication is a major rule of digital hygiene.
