Many users, when they first encounter the Android ecosystem or switch to Xiaomi smartphones, often wonder about the safety of their phone numbers. SIM-The card was the standard for making it easy to change devices just by rearranging the chip. POCO, offer much more flexible and reliable tools for managing your address book.
Shifting contacts from a SIM to a Xiaomi phone is not just copying, it is the first step towards a proper digital space organization. The built-in MIUI shell (or the new HyperOS) has powerful import tools that allow not only copying numbers, but also automatically distributing them to the right groups. Ignoring this procedure can lead to confusion when numbers are displayed twice, once from the cloud, and once from a physical medium.
In this article, we will take a look at the details of the process, how to avoid data loss, why it is better to store information in a Google account rather than on a SIM card, and how to clear the phone’s memory of duplicates after the procedure is completed.
Why it is important to transfer contacts to the device
Storing numbers directly in memory SIM-The chip memory is usually limited to a few hundred records, and the data storage format often does not allow to keep full names, extra numbers, email addresses or photos of subscribers. When transferring to Xiaomi’s phone, you get access to the full functionality of the address book.
In addition, a SIM card is a physical object that is easily damaged, lost or forgotten in another device. If you store important numbers only there, the risk of losing them is extremely high. Modern Xiaomi smartphones offer synchronization with a Google account, which makes your data available from any device in the world, access to the Internet.
- 📱 Extended fields: the ability to save not only the number, but also email, position, address and notes about the person.
- ☁️ Cloud security: Automatic backup prevents data loss when a gadget breaks down or is stolen.
- 🔍 Smart search: quick search by name, surname or even part of a number, which is impossible when reading directly from the SIM.
⚠️ Before you start any contact transactions, make sure that your SIM-The card sits tightly in the tray, and extracting the card during the import process can lead to reading error and partial data loss.
It’s also worth noting that the Android operating system on Xiaomi devices is optimized to work with large databases. Importing from a SIM card to a phone takes seconds, even if you have several hundred records. This action frees up the memory of the SIM card itself, which can be useful if you plan to use it in an old button phone or a phone. GPS-Tracker where memory is critical.
Preparation for data portability
Before you start active, you need to perform several preparatory steps, this ensures that the process goes smoothly, and no number is lost. SIM-If you have a dual-SIM device, make sure you know which slot (1 or 2) has the right numbered chip in it.
The second important step is to check the available space. Although the contacts take up a minimum of space, a crowded phone memory can cause system failures as a whole, and it is also recommended to make sure that the battery charge is at least 20-30% so that the device does not turn off at the most inopportune time.
☑️ Checklist before import
If you use a locking system SIM-map PIN-If you first turn on the phone or after you restart, the system will ask for a code to unlock the chip. Without this step, access to the contacts on the SIM will not be possible, and import will not take place.
| Parameter | Recommended value | Impact on the process |
|---|---|---|
| Battery charge | More than 20% | Prevents shutdown during recording |
| Internet | Not mandatory. | It is only necessary to sync with Google after |
| Phone memory | Free >50MB | Ensure stable operation of the system |
| SIM lockdown | Unlocked. | It is necessary to read the chip data |
💡
If you just bought a new Xiaomi phone, don’t rush to insert the old one. SIM-First, set up your Wi-Fi and log in to your Google account, which will allow the system to immediately suggest synchronizing old contacts from the cloud, if they were saved there.
Step-by-step: import through the Contacts app
The easiest and standard way to transfer contacts from the SIM to the Xiaomi phone is to use the built-in Contacts app. The interface may vary slightly depending on the version of MIUI or HyperOS, but the logic of actions remains the same for all models, whether it is Redmi Note or flagship Xiaomi 14.
Open the Contacts app on the home screen or in the Tools folder. At the bottom of the screen, find the menu button (usually three dots or a person with a gear icon) and click on it. In the list that opens, select Import Contacts.
The system will tell you to choose the source of the data. SIM-If you have two SIMs, select the one with the numbers on it (SIM 1 SIM 2) Then the phone will suggest you choose your destination, and it is critical to choose the right option: "Phone" or, even better, your Google account.
Once you have selected your source and destination, click the Import or OK button, and it takes seconds to a minute to complete, and you will see a successful copy notification, and your numbers are now available in the device's memory and are independent of the physical SIM card.
- 📂 Source selection: clearly define which SIM to read data from if there are two of them.
- 💾 Save Place: Choose a Google Account for Automatic Sync and Security.
- ✅ Confirmation: Wait for a pop-up notification of successful completion of the operation.
⚠️ Attention: Don't pull out SIM-While reading is fast, interrupting the writing process in the phone memory can damage the contact database and you will have to clear the app's cache.
Alternative method through system settings
If for some reason the standard Contacts app doesn't open or doesn't work properly, you can use system settings, which are deeper and allow you to manage imports at the Android level, and it's especially useful if the application interface has been changed by third-party launchers.
To do this, go to the Settings menu of your Xiaomi smartphone. scroll down to the App section or search by settings by entering the word “Contacts.” You need the Contacts System App. Inside, find the Import and Export section.
The algorithm is similar: choose to import with SIM-The system can request permission to access the storage — you must agree, otherwise the recording will not be possible. Next, you should select the account to which the data will be downloaded.
What happens if the importation point is inactive?
Using system settings sometimes allows you to see more detailed statistics: how many contacts are found, how many of them do not have a name (only number), and how many will be missed due to format errors, which gives more control over the process for advanced users.
Removing duplicates and combining records
A common problem after data transfer is duplicates, which happens if you've previously saved numbers to a phone or cloud and now copied them from a SIM card, and as a result, one person can have two cards: one with a full name, the other with a simple number. Fortunately, Xiaomi provides a great tool to solve this problem.
Go to Contacts, click on the menu (three dots) and select Contact Organization or Contact Management. Find the option to Combine Repetitive Contacts. The system will analyze the database and suggest a list of pairs it believes belong to the same person.
You can view each pair and confirm the pairing manually, or click the "Unite All for Auto Clean" button, and after that, your phone book will be clean and structured, and all calls and messages from these people will now be displayed with a single card containing all the information available.
- 🔍 Analysis: the system itself finds matches by phone number.
- 🧹 Cleanup: Removing empty or incorrect entries left over from old SIM cards.
- 🔄 Sync: Once combined, changes will automatically update in the Google cloud.
It's important to understand that when you combine information, you add up information, and if you have only a number in one record, and then you have a number, a name, a photo, a number in the second record, then you're going to have a name, a photo, a number, and you're not going to lose it, but you're consolidating it.
💡
Regular checks for duplicates (once a month) help to maintain order in the phone book and speed up the search for the right subscribers.
Set up sync with Google Account
Once you have migrated contacts from the SIM to the Xiaomi phone, it is critical to set up their storage in the cloud, which ensures that when you lose your phone or switch to a new Redmi or POCO model, you do not have to repeat the import procedure manually.
Go to Settings → Accounts and Sync (the path may be slightly different: Passwords and Security → Sync). Find your Google account on the list and make sure the switch opposite Contact is activated. If the slider is grey, turn it on.
Also check where the new numbers are saved by default. In the Contacts app, there is an Account for new contacts in the settings. Choose your Google account instead of Phone or Phone «SIM-This will prevent local copies from accumulating and ensure that every new number is backed up instantly.
⚠️ Note: If you see contacts saved on Phone instead of Google, they don't sync. If you reset to Hard Reset, those contacts will be permanently deleted. Move them to your Google account via the export/import function.
To check, go to contacts.google.com from your computer, and if you see your numbers there, it means that the sync is working correctly, and that's the most reliable storage available on Android.
