Changing a smartphone is often stressful, especially when it comes to personal data. Xiaomi Redmi 10S owners who switch from button phones or other Android devices often wonder how to quickly and error-free move the phone book. Contacts are perhaps the most important information that is unacceptable to lose.
The MIUI operating system on Redmi 10S has a very convenient data import process, but it has its own nuances that need to be taken into account. Standard system tools allow you to transfer records in just a few touches, but to successfully complete the operation you need to know where to look for the right settings.
Modern smartphones offer not just copying, but synchronization with cloud services, which is a more reliable way of storing. However, physical transfer from the operator’s card remains a relevant method for those who do not trust the cloud or have just activated a new device.
Preparation of SIM-card and compatibility check
Before you start active transfer, you need to make sure that the physical health of the storage medium. SIM card must be properly installed in the tray of the device. Redmi 10S model uses a combined slot, so it is important not to confuse the orientation of the chip during installation.
Older carrier cards may have limited storage and specific storage formats. Some records may not be displayed due to character limitations in the name or no support for additional fields (address, email) on the old media side.
It's also worth making sure that the smartphone reads the card correctly. 10S The network icon should appear in the notification curtain if the operator name is displayed as "No" SIM-Imports will not be possible until the problem with reading the chip is resolved.
⚠️ Attention: Don't pull out SIM-This can damage the file system of the map and lose some of the records without the possibility of recovery.
Make sure your phone has enough internal memory. Although contacts take up as little space as possible, a crowded drive can cause errors in the system applications that run the phone book.
💡
Before you start any data manipulation, back up your current phone book through Mi Cloud or Google Account to have a rollback point.
Standard method of import through the system menu
The basic method of data transfer is built directly into the standard Contacts or Phone application, which is the preferred method, since it does not require the installation of third-party software and ensures the correct distribution of the number and name fields.
To start, open the Contacts app on the home screen or in the Tools folder. At the bottom of the screen or in the top corner (depending on the MIUI version), find the menu button represented by the three dots or the gear icon.
☑️ Algorithm for Importing Contacts
In the menu that opens, select Import Contacts, and the system will suggest you select a data source. SIM-Once the source is selected, the smartphone will scan the memory of the chip.
You can then store the numbers in your device's internal memory or directly into your Google account, and the second option is preferable because it automatically syncs. Click OK or Import to start the process.

|---|---|---|
| Source | Physically SIM-map | Make sure you read the map. |
| Appointment | Phone Memory or Google Account | Select a Google Account |
| Format | vCard or MIUI system format | Automatic. |
| Duration | Depends on the number of records. | Don't interrupt the process |
Use of the “Contact” app from Google
Many Xiaomi devices, including Redmi 10S, have a Google-branded call and contact management app preinstalled, and the interface may be different from the system, but the import functionality remains similar.
Launch the Contacts app (with a blue icon). Click on the menu icon (three horizontal bars) in the upper left corner. In the side menu, select Settings, and then search for the Import/Export section.
Here you will be asked to select a source. Click on Import with SIM-The app will request permission to access the contacts, which must be confirmed. Next, select the Google account to which the numbers will be uploaded.
What to do if the import is frozen?
The advantage of using Google services is cross-platform, and the data stored in this way will be accessed from any device where you log in to your account, whether it is a tablet, another smartphone or a computer through a browser.
Solving Common Problems When Copying
Users may experience a variety of errors in the process of transferring data, and one of the most common problems is the message that no contacts have been found, which can occur if there are no records on the card or they are written in a format that is not readable by the current version of MIUI.
Sometimes the system reports an import error due to memory overflows or name conflicts, and if you have duplicate numbers with the same names, the system may miss them or create conflicting records, in which case it helps to pre-clean the card in another phone.
⚠️ Note: If the contacts are not identified as characters when you import, the problem is encoding. Try copying the contacts first to another Android smartphone and then to Redmi. 10S.
It's also possible that only a fraction of the numbers are copied. SIM-A card that often has a limit not only on the number but also on the length of the name (usually up to the length of the name). 20-30 Long names can be cut off.
- 📱 Check if you have chosen correctly SIM-card if there are two of them on the phone (use slot 1 or 2).
- 🔄 Make sure that the Contacts app has all the necessary permissions in the privacy settings.
- 💾 Free up space in internal memory if your smartphone signals a shortage of resources.
In rare cases, resetting the Contacts app helps. Go to Settings → Apps → All Apps → Contacts → Clear. This won’t delete your numbers, but will return the app’s settings to their original ones.
Alternative methods and third-party utilities
If Xiaomi’s standard tools don’t work, you can use proven third-party solutions. Google Play offers a variety of application managers specializing in working with the phone book.
One popular solution is the Copy My Contacts app, or peer-to-peer software, which allows you to not only copy, but also edit, combine duplicates and format data before saving, which is especially useful when you switch from old button phones.
Another method is to use Bluetooth or file managers if you can upload contacts from another phone to a.vcf file. This file is then transferred to Redmi 10S and opened, after which the system will prompt you to import the content.
Using carrier cloud services is also possible, but requires mobile internet and often paid subscriptions, a method that is less universal because it ties you to a specific carrier and its ecosystem.
Organization and security of stored data
Once the import procedure is completed successfully, it is recommended to conduct an audit of the phone book, remove duplicates that may have been created by the data merger from different sources, and for this purpose, the Contacts app has a built-in Merger function.
Make sure to set up automatic sync. Go to Settings → Accounts and Sync. Make sure your Google account is ticked “Contacts” in front of you, which ensures that if you lose or break Redmi 10S, your numbers will be saved.
💡
Regular sync with your Google account is the only way to guarantee 100% security of contacts in case of any hardware failure.
Don’t keep important contacts exclusively on SIM-This medium is not designed to store large amounts of data in a long-term and reliable way, but rather to be used as a network identification tool, not as a backup.
- 🔒 Check who has access to your Google account and enable two-factor authentication.
- 📂 Create contact groups (Family, Work, Friends) for easy navigation and mass mailing.
- 📸 Add photos to contacts for quick visual search in call log.
⚠️ Note: When selling or transferring a phone to a new owner, make sure to perform a full Hard Reset, making sure that all data is synchronized with the cloud.
