Changing a mobile device or switching to another operating system often challenges users to quickly and safely transfer their phone book. Owners of Xiaomi brand devices, including Redmi and Poco sub-brands, may face the need to copy accumulated contacts directly to a plastic SIM card. This is a classic backup method that guarantees access to numbers even if the smartphone itself is completely lost or broken.
But the current approach to storing data in the Android ecosystem and the MIUI shell offers more flexible and reliable synchronization options. It’s important to understand the difference between physical storage on a SIM chip and cloud synchronization via a Google account or Mi Cloud. In this article, we’ll take a look at how to save your SIM card numbers on a shaomi, and look at alternative, more modern methods that will keep your data from being lost.
The contact management process on the Chinese manufacturer’s devices has its own interface and logic of standard applications. Regardless of the firmware version, whether it is a global version or a Chinese build, the basic principles remain similar, although the names of menu items may differ slightly. Below is a detailed guide to help you organize the phone book.
Preparation for transfer and check of contacts
Before you start taking active actions to copy data, you need to make sure that your SIM-The card is correctly defined by the system and has free space to write. Older Mini-SIM or Micro-SIM cards can have memory limitations, often preventing you from keeping numbers longer. 10-12 Add additional fields such as email or address, and modern Nano-SIM cards usually do not have these problems, but you will not need to check them.
Open the standard Contacts app on your device. MIUI It's often combined with call and call history functions, so you have to go to the display settings to see where your numbers are stored right now, if your contacts are spread across different sources (Google account, phone memory, SIM-map, the copying process may take longer or result in duplicates.
It is recommended to perform a pre-review of records, delete unnecessary or erroneous numbers so as not to clog the memory of the SIM card, also combine duplicate contacts if the system has suggested to do this automatically, a clean and structured database is the key to a successful and fast transfer without errors.
- 📱 Make sure that SIM-The card is set to the correct slot if there are several of them, as some models support writing only on one of the cards.
- ☁️ Check your sync status with your Google account to have a backup in case of a crash when recording to a physical medium.
- 🔋 Charge the device to minimum 40-50%, The process of mass recording may require processor resources.
It is important to note that when copying SIM-The limit of the characters for the name on the SIM is usually about 10-15 So, when you move names, you can use much longer names in your phone or the cloud, so you can actually look stripped down after you move them, which is a normal technical limitation of the format of storage on a chip.
Step-by-step: copying from the phone memory to SIM
The basic method of number transfer is built directly into the contact management application. The algorithm of actions can vary slightly depending on the version of the MIUI shell, but the general logic remains unchanged. First, you need to open a list of all contacts and choose the ones you want to move.
Click the menu button, which is usually represented by three dots or vertical bars in the corner of the screen, or use the "More" button. In the drop-down list, find Settings or Contact Management. This is where import and export functions hide. Select the option to copy contacts (or import/export).
☑️ Pre-copying check
The system will suggest you select a copy source, specify your phone or device if your numbers are stored locally, and then select your destination. SIM-Confirm the action, and the transfer process begins. Depending on the number of records, it can take anywhere from a few seconds to a couple of minutes.
⚠️ Note: When copying the SIM-Contact photo card, social profiles and additional numbers (work, home) will be lost, as the SIM card format supports only one name and one primary number.
Once the operation is complete, it is recommended to remove the SIM card and insert it into another phone to check the integrity of the data, which will make sure that all the numbers are read correctly, and if you plan to use the SIM card in a new device, this will be the final stage of preparation.
Use of Google and Mi Cloud Services
Keeping contacts on a physical SIM card is a time-tested but somewhat outdated method. The more efficient and modern solution is synchronization with cloud services. Xiaomi users have two main options: a Google account and their own Mi Cloud, which allows not only saving numbers, but also instantly restoring them to any new device when they sign in.
To activate sync with Google, go to Settings on your smartphone, look for Accounts and Syncs (or just Accounts). Select your Google account from the list. Make sure the switch opposite Contacts is activated. From now on, all changes to the phone book will automatically be reflected in the cloud.
💡
Check contacts.google.com regularly from your computer to make sure all your numbers are properly synced and stored in the cloud.
Similarly, Mi Cloud works. Go to Mi Account settings, select Cloud and enable contact sync. The Xiaomi ecosystem has the advantage of being able to restore remote contacts via the web interface within 30 days, which is a great insurance against accidental data loss.
Using cloud technology eliminates the binding to a specific plastic storage medium. You can lose your SIM card, break your phone, but your contacts will remain secure and accessible immediately after you install Google Contacts or log in to your Mi Account on a new gadget. This is especially true in the era of eSIM, where there is no physical storage medium.
Export and import via vCard (.vcf)
Another reliable way to save and transfer a phone book is to back up a vCard file (extension.vcf) that is universally supported by almost all phone manufacturers and email clients, and can be saved to internal memory, an SD card, or sent to an email.
To create such a file, open the Contacts app, click on the menu (three dots) and select Settings. Find Import and Export Contacts. Choose Export to Device Memory or Export to File.vcf. The system will suggest choosing which contacts to export (all or only from certain accounts) and where to save the file.
Where can I find the saved vCard file?
To restore contacts from a file on a new phone or after a reset, perform a reverse operation. From the import/export menu, select Import from the device memory or Import from the file.vcf. Find the previously saved file in the list and confirm the action. All contacts will be added to the selected account or phone memory.
This method is especially useful when switching from other brands (such as Samsung or iPhone) to Xiaomi. vcf file can be transferred via Bluetooth, messengers or email, making the process of data migration as simple and independent of the speed of the Internet connection.
Comparison of Storage Methods: SIM, Phone, Cloud
The choice of how to store contacts depends on your priorities: whether you need maximum compatibility with old phones or you value the functionality and security of modern solutions. Below is a comparison table that will help determine the best option for your situation.
| Parameter | SIM-map | Phone memory | The cloud (Google/Mi) |
|---|---|---|---|
| Capacity | Limited (usually 250-500 rooms) | Depends on the free memory of the device | Virtually unlimited. |
| Length of name | Limited (often circumcised) | Full support for long names | Full support |
| Supplementary fields | Only number and name. | Photo, email, address, social media | All fields + history of changes |
| Security | Risk of loss when the SIM fails | Risk of loss when your phone breaks | High (access from any device) |
As you can see from the table, the storage SIM-The card is far inferior to cloud technology in functionality, but if you need to quickly transfer the number base to a button phone or device without Internet account support, the SIM card remains the only universal solution.
For everyday use of the Xiaomi smartphone, the most sensible strategy is a combined approach: the main database is stored in the Google account with synchronization enabled, and critical numbers (for example, emergency services or contacts of relatives) can be duplicated on a SIM card in case of a full discharge of the smartphone and the need to use another device.
Solving problems and eliminating mistakes
Users may encounter various difficulties in copying or synchronizing, and one of the common problems is reporting a lack of space. SIM-In this case, the system will suggest you select the contacts to copy manually, start with the most important numbers, and leave the less used ones in the memory of the phone or the cloud.
Another common problem is the appearance of duplicates. Once you import from a SIM card into your phone, you may have two contacts with the same name. The Contacts app on MIUI has a built-in unification function. Go to the contact settings and select Combine Repeated Contacts. The system will automatically find matches by number or name and suggest combining them into one record.
If contacts are not synced with Google, check the date and time settings on your device. Incorrect times can block a secure connection to servers. Also make sure your account settings don't limit data transfers to Wi-Fi only if you're trying to sync over a mobile network.
⚠️ Note: Never delete contacts from the SIM-The cards are immediately after you copy them, until you make sure 100% that they are correctly displayed at the new destination.
