Owning a Xiaomi smartphone opens up a host of convenient ecosystem features, but keeping your personal data safe should always be a priority. Many users are faced with having to move a number list from the device's internal memory or the device's internal memory. SIM-Maps to cloud storage to protect yourself from accidental loss of information.Sync contacts with a Google profile is the most reliable way to ensure access to the phone book from any device, whether it is a new smartphone or computer.
The process of migrating data to the MIUI shell or the new HyperOS has its own features that set it apart from standard Android. The wrong setup can lead to new numbers being stored only in the phone’s memory, not in the cloud. In this article, we will discuss all the steps in detail so that you can be sure of the security of your data.
Preparing a Google account and checking the connection
Before you start any data manipulation, you need to make sure that your smartphone is logged in. Without an active Google Account, synchronization is technically impossible. Check for an Internet connection, as data transfer requires a stable communication channel, preferably via Wi-Fi to save traffic.
Go to your device settings and find the account section, which shows all the services your Xiaomi is connected to, and if you don't have a Google account, you need to add it manually by entering your username and password.
Make sure your device is synced specifically for contacts. Often, the main account is added, but the phonebook sync slider has been disabled by the user before.
⚠️ Note: If you are using two-factor authentication, make sure you have access to a phone number or backup code, as the system may request a sign-in confirmation when you first sync on a new device.
Checking the connection status is a fundamental step that leads to errors when saving. Make sure the date and time on the device are set automatically, as time desynchronization can block the connection to Google servers.
Import contacts from the phone memory and SIM-map
If your numbers are already on the device but stored locally, they must be exported to the cloud profile. Xiaomi’s standard Contacts app has built-in storage management functionality.
Open the phonebook app and go to the settings that are usually hidden in the three-dot or gear menu, and find the item "Import/Export contacts," where you will be asked to choose a data source.
- 📱 Select “Import from Device Memory” if the numbers are stored locally.
- 💾 Select "Import with" SIM-cards" if the data is on the operator's chip.
- 📂 Select “Import from.vcf” if you have a backup.
Once you have selected a source, the system will ask where to save the data, and it's critical to choose a Google account over a Phone or a Mi Account, only then the numbers will go to the cloud and be available after you reset.
☑️ Import checklist
The copying process can take from a few seconds to a couple of minutes depending on the number of records, and during the operation, it is not recommended to switch between heavy applications so as not to interrupt the system.
Automatic synchronization in MIUI and HyperOS
Single import is good, but constant automatic synchronization ensures real data security. In the shells of MIUI and HyperOS, synchronization settings can be spread across different menus, which sometimes causes confusion among users.
To activate a continuous update, go to Settings → Accounts and Sync → Google. Here you will see a list of all services that can be updated in the background. Search in the Contacts list and make sure the switch is active.
It’s also worth checking the settings of the contact app itself. In some firmware versions, there is a separate sync menu inside the Contacts app, where you can select your default account to save new records.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Synchronization of contacts | Included. | Automatically save new numbers |
| Synchronization over Wi-Fi | Turned off (for instant update) | Allows you to update data via mobile network |
| Frequency | Automatically. | Determined by the system depending on changes |
| Default account | Google (your email) | Where do new contacts remain? |
If you notice that sync is not happening, try clearing the cache of Google Play services.This often solves problems with hanging data exchange processes in the background.

Solving Common Problems in Transfer
Despite the smooth processes, Xiaomi users may experience data porting errors, often in overcrowded account storage or duplicate entries conflict.
If the system produces a sync error, the first thing to do is check Google's storage status. The 15GB limit is shared between Mail, Drive and Photos, and exceeding it blocks contact updates. It's also worth checking if the account is blocked by Google security services due to suspicious activity.
- 🔄 Clear the Contacts app data through the App Settings menu.
- 🔐 Reconnect your account by deleting it from the system and adding it again.
- 🌐 Check if antivirus or firewall block connection to Google servers.
Duplicate contacts are another common problem. SIM-You can create two copies of the same number from your phone and from your card memory. Use the "Contacts Unite" function in the application or through the Google Contacts web interface to solve this problem.
⚠️ Note: When manually removing duplicates, be careful not to delete the main entry with important data, leaving only an empty copy with the help of the original copy. SIM-Always check the contents of the card before deleting it.
In some cases, resetting sync settings helps. Go to Settings → Apps → All apps → Google Play Services → Storage → Clear data. This will not delete your personal files, but reset the sync settings.
💡
Tip: Check the “Cover and Manage” section of the Google Contacts web version regularly, where the system itself offers to combine similar contacts and delete empty entries.
Using Mi Cloud as an Alternative Storage
Xiaomi smartphone owners have the unique opportunity to use the branded Mi Cloud.It is a great alternative or addition to Google services, especially if you plan to stay in the brand ecosystem.
To activate, go to Settings → Mi Account → Mi Cloud. Make sure the Contacts switch is activated. The system will prompt you to combine local data with the Mi cloud.
The main advantage of Mi Cloud in this context is the ability to quickly restore numbers when you switch to another Xiaomi or Redmi smartphone without having to log in to a Google account again for each service. However, for cross-platform (for example, access from an iPhone or another Android), Google remains a more versatile solution.
It is important to understand the difference: when synchronization with both services is enabled, new contacts can be created in different places, and you need to carefully monitor which account is selected by default for saving to avoid chaos in the phone book.
💡
The optimal strategy is to use Google Contacts as the primary storage for cross-platform, and Mi Cloud as a backup sync channel exclusively for Xiaomi devices.
Results Checking and Online Data Management
After all the procedures are done, you need to make sure that the data actually entered the cloud, and the best way to verify it is to view the contacts through a browser on a computer or other device.
Go to contacts.google.com and log in to your account, and if you see your entire number list, you've been successful in syncing, and you can easily edit, add photos, and group your contacts.
Managing data via a web interface is often more convenient than from a phone, you can massively delete unnecessary records, restore contacts from the archive (they are stored there for 30 days), and export the entire database in CSV or vCard format.
Regularly checking the web version helps to detect desynchronization at an early stage, if you add a number on your phone but it is not on the site after 5-10 minutes, then the system has crashed, which requires intervention.
