Replacing a smartphone with a new model from Xiaomi is always an exciting moment, coupled with the expectation of improvements in performance and camera quality. However, the first and most important step for any owner is to integrate into the device of your familiar device. SIM-Many users mistakenly believe that it is enough to simply insert a plastic card into the tray, but modern Android and shell. MIUI HyperOS offers much deeper synchronization capabilities.
The data migration process can vary depending on which device you are switching from: an old button phone, an iOS-based smartphone or another Android device. SIM-So to work properly, you need to set up VoLTE, move your contacts to the cloud, and maybe activate a virtual SIM card if your carrier supports this technology. In this article, we will discuss all the stages in detail so that you can start using the new gadget without losing important numbers and communication settings.
Physical installation SIM-card-depending
The first step is always the physical installation of the communication module. Modern Xiaomi smartphones use different tray formats, and it is important not to damage the extraction mechanism. The standard solution for most mid-range and flagship models is a combined slot 2 Nano-SIM + MicroSD or a hybrid version of Nano-SIM + Nano-SIM. You will need a special clip that comes with the kit, or a thin needle.
When you pull the tray, pay attention to the force of pressing. If the tray doesn't come out with a light tap, you may be pushing the wrong hole. In some budget models, the tray can be aligned with the volume button or be on the bottom edge next to the port. USB Type-C: Never try to get stuck. SIM-card in a microSD slot, as this is guaranteed to break the contact group.
Once the card is installed and the device is turned on, the system must automatically identify the operator. If this does not happen, check if you have correctly positioned the card relative to the bevelled angle. The network indicator will appear on the screen, and the phone will prompt you to adjust the Internet settings. In some cases, manual APN input is required, although Xiaomi usually downloads them automatically through the database.
☑️ Pre-installing check SIM
Transferring Contacts via Mi and Google Account
The most reliable and modern way to transfer numbers is using cloud services. Xiaomi ecosystem is closely integrated with its own Mi Cloud, which allows you to synchronize contacts, SMS, call history and even notes. To get started, you need to log in to the system by going to Settings → Mi Account. If you move from another Android smartphone, make sure that the old device also has a sign in to Mi Account and synchronization is enabled.
An alternative and often more versatile method is to use a Google account. Contacts saved in Google Contacts will automatically appear on the new Xiaomi immediately after you enter your email address when you initially set up the system.This is especially handy if you plan to change your phone again in the future, as the data will be tied to a cross-platform service, rather than the manufacturer of the gadge.
To manually activate sync on a Xiaomi device, go to Settings → Accounts and Sync. Here you will see a list of all the services connected. Select the account you want and make sure the switch opposite to Contacts is active. Click on Sync or three dots in the corner of the screen to force data updates. This method eliminates loss of information even if you accidentally reset your settings to factory.

Using the Mi Mover app for migration
If you change your phone completely, not just change it. SIM-The perfect tool is the built-in Mi Mover app, which allows you to transfer data over Wi-Fi Direct, which provides high speed transfer without using Internet traffic. The application is preinstalled on all Xiaomi smartphones, and for devices of other brands (iOS or Android), it can be downloaded from the app store.
The process starts with running the program on both devices. On the new Xiaomi phone, select the role "I am the recipient" and on the old one, "I am the sender." The camera of the new smartphone will scan the new one. QR-code that appears on the screen of the old device, after which a secure connection will be established between the gadgets, you can choose what to transfer: contacts, messages, photos, applications and even system settings.
When migrating from iOS to Android, the app may request additional permissions. Once the process is complete, all numbers usually end up in the phone’s local memory. It is recommended to export them immediately to Google or Mi Account, so as not to depend on local storage, which can be cleaned up when crashes.
Set up eSIM on Xiaomi smartphones
The eSIM (Embedded SIM) technology is gaining popularity by allowing virtual SIM card use without a physical media. Owners of Xiaomi flagship models such as the 13, 14 or Mi 11 Ultra series have the ability to activate a profile directly from the settings. This frees up the physical slot for a second SIM card or memory card, which is critical for hybrid trays.
You will need to activate eSIM. QR-code from your mobile operator, which can be obtained from your personal account or sales office. Go to the Settings menu → SIM-maps and mobile networks → Add a data plan. The camera will open to scan the code. It is important to ensure a stable connection to Wi-Fi at the time of downloading the profile, since the data volume can be significant, and the process requires a constant connection to the activation server.
⚠️ Note: When resetting your phone, the eSIM profiles may be removed from the factory.Be sure to back up your profiles before performing Hard Reset or check with the operator for a re-activation procedure, as you can do so before you do Hard Reset. QR-code is often a one-time.
Once you have successfully installed a profile, you can switch between a physical SIM and eSIM, assign them for different purposes (e.g., one for calls, one for the Internet), and manage profiles in the same menu where you can rename them for convenience, such as "Work" and "Personal." Some operators allow you to store multiple profiles at the same time, activating the desired one as needed.
Import of contacts from files and other sources
In situations where cloud services are not available or you are switching from a button phone, the method of importing from files remains relevant. The standard format for saving numbers is.vcf (vCard), you can save this file to a computer, a flash drive or transfer it via Bluetooth, and then import it into the Xiaomi phone book.
To import, open the Contacts app, click on the menu (three dots or profile icon) and select Import Contacts. The system will prompt you to select the source: file from the device, SIM-If you have selected a file, specify the path to it. The system automatically recognizes the format and suggests you choose an account to which the numbers will be saved (Google or Mi Account is recommended).
Sometimes there is a problem with encoding, when instead of letters, Krakozabras are displayed. This often happens when importing from old.csv files. In this case, it is better to first convert the file to.vcf format on the computer, using standard utilities or online converters, ensuring UTF-8 encoding, this ensures the correct display of Cyrillic and special characters.
| Transfer method | Speed. | Reliability | Better for you. |
|---|---|---|---|
| Mi Cloud / Google | Tall. | Maximum | Constant synchronization |
| Mi Mover (Wi-Fi) | Very high. | Tall. | Full phone replacement |
| File.vcf | Medium | Medium | Backup |
| Bluetooth | Low. | Low. | Transmissions of 1-2 contacts |
Solving Typical Network Definition Problems
After the transfer SIM-Users sometimes encounter a situation where the phone sees the card, but the network does not catch or writes "No service." SIM-karga PIN-If you change your phone and you don't change the code, it could be the standard carrier code (often 0000 or 1234), but it's better to check with the provider.
The second common cause is frequency band incompatibility or lack of support. 4G/LTE specific SIM-Try to manually select the network in the settings: Settings → SIM-maps and mobile networks → Network selection: Turn off automatic selection and wait for the list of available carriers.
