Moving to a new smartphone or restoring data after a system reset are processes familiar to many owners of modern technology. A particularly pressing issue for ecosystem users Xiaomi is the migration of the phone book from the old SIM cards to the internal memory of the device. Despite the widespread use of cloud services, physical storage media still store thousands of important numbers that cannot be lost.
The shell interface MIUI and the new HyperOS has a high degree of customization, which is why standard menu paths may differ from "pure" Android. This often causes confusion among users who are used to other brands. In this article, we will analyze in detail all the legitimate methods of importing data, the features of working with two SIM cards and the nuances of synchronization with Mi Cloud.
Before proceeding with technical manipulations, you need to make sure that the card is physically working and the slot is working correctly. Modern Xiaomi smartphones use combined slots, where the second compartment can be occupied by a memory card, which blocks the installation of a second SIM. Make sure that the chip is installed correctly and the system sees the operator’s network.
Preparing the device and checking the visibility of contacts
The first stage of work is diagnostics: the system must correctly read data from the telecom operator's chip. Go to the standard application Phone or Contactthat is preinstalled on the system. If the list is empty, but calls are being made, it means that the numbers are physically located on the map, but are not displayed in the interface.
In the display settings, the default filter is often “Phone only” or “Google account only”. You need to change this setting. Open the application menu (three dots or stripes in the corner) and find the item Display settings. Here you should select the option All contacts or specifically indicate your SIM card.
Sometimes the problem lies not in the filter settings, but in the data storage format. Old cards could store numbers in outdated encodings, which modern smartphones interpret incorrectly. If you see a bunch of characters or empty lines instead of names, try removing the card and inserting it into a simpler device for an initial check.
⚠️ Attention: Do not try to edit or delete contacts directly from the SIM card through third-party managers without creating a backup copy. An error during the recording process can lead to complete loss of data without the possibility of recovery.
After making sure that the system “sees” the card, you can proceed to the copying procedure. This step is critical, since storing the numbers on the chip limits the length of the name (usually to 10-15 characters) and does not allow you to add additional data, such as email or address.
Before starting the transfer, make sure that the smartphone battery charge is at least 30% to avoid a power outage at the critical moment of data recording.
Classic method of importing through the app Contacts
The most reliable and time-tested method of data transfer is built directly into the standard call management application. This method does not require an Internet connection and works locally, which guarantees high speed of the process even with a large volume of records.
The algorithm of actions is quite simple, but requires care when choosing a source and destination. Open the application Contact and go to the settings menu, hidden under the gear icon or three dots. Find the section Import and export of contacts.
In the menu that opens, the system will offer several scenarios. You need item Import from SIM card. If two cards are installed in the device, the smartphone will ask for clarification: which one SIM 1 or SIM 2 the data needs to be read from. Select the desired slot.
- 📱 Select the target storage: phone, Google account or Mi Account.
- 📂 Confirm the selection of contacts: you can mark all at once or select individual entries.
- 💾 Wait end of the process: the progress bar will show the copying status.
- ✅ Check the result: make sure that all numbers appear in the list.
After confirming the selection, the system will begin reading the records one by one. The operation time depends on the card capacity and the number of stored numbers. Typically the process takes from a few seconds to a couple of minutes. Upon completion, you will receive a notification about the successful import.
☑️ Checking the successful import
It is important to note that when imported into the phone's memory, the data becomes available only on that specific device. If you lose your phone or do a factory reset, the numbers will disappear. Therefore, it is recommended to set up synchronization with the cloud immediately after import.
Import through system settings and SIM card management
An alternative path to the copy function is through the global operating system settings. This method may be useful if the Contacts application shortcut has been removed or changed by the launcher, and you cannot find the standard interface.
Go to the menu Settings of your smartphone Xiaomi. In the list of parameters, find the section Applications or use the settings search by entering the query "SIM". You need the item SIM card management.
Inside this menu, information about operators, network types and balance is displayed. Scroll down to the additional actions block. There is often a button Copy contacts or Import from SIM. Clicking on it will launch the same system module as in the previous method.
This method is especially convenient for users who are used to managing all communication parameters from a single center. It allows you to immediately assess the network status and the availability of contacts without switching between different applications.
⚠️ Attention: The interface of the "SIM Card Management" menu may differ depending on the version of MIUI (12, 13, 14) or HyperOS. If you do not find the import button, use the settings search or the Contacts application.
Some users prefer this path, as it seems more “systemic” and reliable. However, functionally, both methods are identical and access the same system API to read data from the security chip.
Synchronization with cloud services for security
Simply copying contacts to the phone’s memory is only half the battle. For complete data security, you need to set up automatic uploading to cloud storage. This will protect your phone book from loss if the device is lost or broken.
Smartphone owners Xiaomi have two main options: using your own service Mi Cloud or standard synchronization Google Contacts. Both options are reliable, but have different features of integration with the ecosystem.
To activate Mi Cloud, go to settings, select the top item with your account name and go to section Mi Cloud. Make sure that the switch opposite the item Contact is active. The system will offer to combine local data with cloud data - agree to this action.
| Parameter | Mi Cloud | Google Contacts |
|---|---|---|
| Free volume | 5 GB (total) | 15 GB (general) |
| Integration | Deep in MIUI | Standard for Android |
| Recovery | Through phone settings | When logging into your account |
| Web version | i.mi.com | contacts.google.com |
Using a Google account is often preferable for those who plan to change their smartphone brand to any other Android device in the future. Synchronization occurs automatically in the background if there is Internet access.
Two-factor authentication and enabled synchronization are the only guarantee that you will not lose your numbers if your smartphone is stolen or broken.
Regularly check the synchronization status in your account settings. If the cloud icon with a checkmark does not appear for a long time, try manually updating the data or reconnecting to the Wi-Fi network.
Working with duplicates and merging records
A common problem after importing data from a SIM card is the appearance of duplicates. The same number can be saved both on the card and in the phone, or contacts from different sources (Google, SIM, phone) create several cards for one person.
Modern versions of the shell MIUI are equipped with a built-in tool to solve this problem. In the application Contact find the section Contact management or Clearing duplicates. The system will automatically scan the database.
The algorithm will prompt you to combine the found pairs. You can do this automatically for all entries, or manually review each pair to decide which information to prioritize. This is especially important if the SIM card contains a short name, and the phone contains a full name with a photo.
- 🔍 Click "Find duplicates" in the control menu.
- 👥 Review the proposed pairs for merging.
- 🧹 Confirm merging records.
- 💾 Save changes to the database.
Manual cleaning takes more time, but allows you to preserve important details that might have been lost during the automatic merge. For example, you can save a work number from one card and a home address from another.
What to do if duplicates are not found?
If the built-in utility does not find duplicates, and you see them visually, try installing a third-party application for managing contacts from the Google Play Store, for example, Contacts Optimizer, which uses more complex comparison algorithms.
After cleaning the database, it is recommended to check synchronization with the cloud again so that the changes are reflected correctly on the server and your other devices.
Possible errors and ways to resolve them
During the copying process, users may encounter various system errors. The most common one is the "Not enough space" or "Import error" message. This may not be due to phone memory (of which there is usually a lot), but to file system limits or access rights.
If the import is interrupted in the middle, do not panic. Check to see if the SIM card itself is full of old entries that the system is trying to read. Try importing contacts in small groups, if such a function is available in your firmware version.
Another common problem is that contacts were imported, but are displayed as “No Name” or with hieroglyphs. This indicates an encoding conflict. In this case, only manual editing of names or using specialized software on a PC to read the card through a card reader will help.
⚠️ Attention: If the phone freezes or reboots when you try to import, remove the SIM card, wipe the chip contacts with a soft cloth and insert it back. The problem may be a bad slot connection.
In rare cases, the problem lies in the application permissions. Go to Settings → Applications → Contacts → Access rights and make sure that access to Phone i Contactsis allowed. Without these permissions, the application will not be able to read data from the communication module.
If you are using a corporate SIM card, please check Check with the operator to see if there is a ban on reading the phone book. Some business plans limit this feature for security reasons.
Frequently asked questions (FAQ)
Can I copy contacts from my phone back to the SIM card?
Yes, this feature is available in the same menu Import and export. Select item Export to SIM card. However, remember that the card has a limited memory capacity (usually up to 250-500 numbers) and does not support long names or additional fields.
What to do if contacts are gone after resetting the settings?
If you previously enabled synchronization with Google or Mi Cloud, just log into your account in your phone settings. Contacts will be loaded automatically within a few minutes if there is Internet access. If synchronization has been disabled, you can restore data from the SIM card by repeating the import procedure.
Why are some numbers not copied from the SIM card?
This can happen if the number is written in the wrong format or contains invalid characters for the current version of Android. Also check if the contact is hidden by filtering settings in the phone book application itself.
Is it safe to store contacts only on the SIM card?
No, it is not reliable. The SIM card may fail, get lost, or be blocked by your operator. In addition, if you replace the card with a new one with a different format (for example, from Mini to Nano via an adapter), the data may be damaged. Always duplicate important information in the cloud.
How to transfer contacts to a new Xiaomi without a SIM card?
Use the application Mi Mover, which is pre-installed on all smartphones of the brand. It allows you to transfer all data, including contacts, photos and applications, from your old phone to a new one via Wi-Fi directly, without using a memory card or the cloud.
