Many users, when switching to a new Xiaomi smartphone or simply recovering data after a reset, face the need to quickly move the phone book. Often old records are stored directly on the carrier’s chip, which was standard practice in the era of button phones. In today’s Android and MIUI shells (or HyperOS), this process requires understanding the logic of the system so as not to lose important data.
Unlike older devices where the SIM card was the only storage, today the smartphone offers several levels of storage: local memory, the manufacturer’s cloud or Google account. Copying contacts from the SIM card to Xiaomi Android is the first step to creating a reliable backup that will not be lost when replacing the plastic from the mobile operator.
Before you start doing any mechanical work, it's important to make sure that the SIM card is correctly identified by the system. If you just inserted a new communication module, give your phone a minute to index the records. Sometimes the MIUI security system may request permission to access the phone book when you first start the application, and this needs to be confirmed.
Device preparation and recording visibility check
Before mass importation, you need to visually assess what is stored on the SIM card. In the Xiaomi interface, this is done through the standard Contacts app, which is often integrated into the phone book. Open it and go to the display settings to select the source "SIM", which will allow you to see the real list of numbers available for transfer and weed out empty memory cells.
It's important to understand the difference between storage formats. A SIM card has extremely limited memory and often crops long names or doesn't support Cyrillic in full, and importing contacts in this case can result in you getting ALEX or a set of question marks instead of Alexander, so you'll need to manually check and edit names after the transfer.
- 📱 Make sure the SIM card is active and has a network signal.
- 🔋 Charge your smartphone to a minimum 30-40% avoiding sudden shutdown.
- 📶 Check if Do Not Disturb mode is enabled so incoming calls don't interrupt the process.
⚠️ Note: If you have a dual-sim phone, the system can suggest choosing which card to copy data from. Be careful when choosing a source, so as not to import duplicates or the wrong phone book.
In some cases, especially on global firmware versions, Google’s Contacts app may be the default instead of the native MIUI app. The interface will be different, but the logic of actions will remain. The main thing is to find a control point that is responsible for the physical SIM card, not for cloud synchronization.
Import through the native MIUI application
Standard algorithm of actions in the shell MIUI It uses built-in management tools. Open the Contacts app, click the three dots in the top right corner (or menu button) and select Import Contacts «SIM-The system automatically counts all available records.
Once scanned, the phone will suggest you choose your destination, and here lies the key: for maximum data security, choose a Google account, not a Phone or SIM. Saving it to a Google account ensures that if you lose or break your phone, all the numbers will instantly recover on any other device after you log in.
The copying process usually takes a few seconds, but with a large volume of records (more than 500) it may take longer.Do not fold the application or lock the screen at this point, as interruption of the process can lead to partial import.
☑️ Checklist of successful imports
If you choose to save your device, the contacts will only be tied to that particular smartphone.This is less reliable, but sometimes necessary to create a local copy before selling the gadget.
Use of the Google Contacts app
Many modern Xiaomi models, especially those designed for the global market, have Google Contacts preinstalled, it has its own interface and a slightly different algorithm of actions. To copy the contacts from the SIM card to Xiaomi Android through this service, open the application and click on the profile icon or the Settings menu.
In the settings menu, find the "Contact Management" or "Import/Export" section. SIM-The system will suggest selecting a Google account to which the numbers will be uploaded, which is the preferred way, as it provides instant sync with the cloud without the need to create additional backup files.
- 🌐 An active Internet connection is required to sync with the cloud.
- 🔄 Automatic Duplication Combination (Google’s Smart Feature).
- 💾 Ability to unload several SIM cards in one list.
The advantage of using the Google ecosystem is that it's intelligently processing data, so if you have numbers on your SIM card that already exist in your cloud, it can suggest that you combine them by updating the information, instead of creating duplicates, which helps keep the phone book clean and tidy.

Solving Common Problems When Copying
Users often experience a phone writing “Contacts not found” or the process stalls, which may be due to damage to the SIM file system or incompatibility of encoding formats. Older Mini-SIM SIM cards cropped under Nano-SIM can work unstable when reading large amounts of data.
Another common problem is limiting the number of characters in a name. A SIM card can store a name up to 10-15 characters long. When importing on Android, these restrictions are removed, but if you make mistakes when copying, try exporting contacts to another, newer SIM card first, and then to your phone.
| Problem. | Probable cause | Decision-making |
|---|---|---|
| Contacts are not displayed | Not selected source of display | In the contact menu, enable display with SIM |
| Import error | Memory overflow or software failure | Restart the phone, free up the memory |
| Distorted names (cracker) | Incompatibility of encoding | Manually edit names after import |
| Only a portion of the numbers are copied. | SIM memory limit (usually 250) | Check the remaining places on the map, remove the excess |
⚠️ Note: If the SIM card is protected PIN-After three mistyping attempts, the card is blocked and you need the code. PUK, which can only be found on the plastic card holder from the operator or in the personal account.
In rare cases, the problem lies in the phone slot itself, if the SIM card doesn't fit well, reading the data can be interrupted, carefully remove the tray, wipe the SIM card contacts with a soft dry cloth and insert it back, making sure that it fits tightly.
💡
Tip: Before mass import, try copying one test contact, and if it appears in the phone book with the right name and number, make sure to run the full import, which will save time in case of errors.
Synchronization and backup of data
Once you have copied the contacts to Xiaomi's SIM card, it is critical to keep them safe in the future. Storing numbers on the SIM card is considered obsolete because of the risk of data loss if the chip is damaged. Regular synchronization with cloud storage is the best solution.
In the settings of your Google account on your Xiaomi phone, you can enable automatic sync. Go to Settings → Accounts and Sync → Google and make sure that Contacts is active. Now any change in the phone book will instantly be reflected in the cloud. You can also use the Mi Cloud cloud, which is deeply integrated into the system.
- ☁️ Mi Cloud allows you to make full system backups, including desktop layout.
- 🔄 Google Contacts are restored even on devices of other brands (Samsung, iPhone).
- 💻 Access to numbers is possible through the browser from any computer.
Don’t rely on just one security method: create local copies in.vcf format and save them to your computer or external drive, which is the “gold standard” of data security that will protect you even in the event of account locks or server problems.
💡
The main idea: SIM card is temporary storage. Always aim to transfer contacts to a cloud account (Google or Mi Cloud) immediately after you buy a new phone.
