Where the contacts are kept: SIM-card or memory of the Xiaomi phone?

Owners of smartphones Xiaomi, Redmi and POCO Often faced with the situation when you buy a new device or replacement SIM-So you have to figure out where the new numbers are written, and that's a critical question, because the storage area is the key to keeping the data safe when you reset or break the gadget. MIUI HyperOS and offer flexible settings, but by default may behave differently than users who are used to push-button phones expect.

Understanding the difference between local storage, Google account and SIM-This article will explain how to check the current status of the save, how to transfer the existing records and what nuances should be considered when working with the address book in the Xiaomi ecosystem.

The main problem is that the visual interface of the Contacts app doesn’t always explicitly indicate the source of each record unless you turn on a special display mode, but there are proven methods to instantly identify where the file with your friend’s or colleague’s phone number is physically located.

How to visually determine the location of the storage room

The fastest way to know where a particular contact is saved is to open a detailed card in a standard application. Depending on the version of the MIUI shell, the interface may be slightly different, but the logic remains the same. If the number is stored in the phone's memory or synced with a Google account, the system usually displays additional fields to add an address, website or notes, which is technically not available for SIM entries.

Notice the top of the screen when you edit, and it often shows the name of the group or account to which the record is attached, and if you see the phone or your email address, the data is stored in internal memory, and if you have the carrier name or simply SIM, the number is written on a chip.

For more accurate diagnosis, you can use the filtering function. In the Contacts app, click three dots in the corner or select Settings, then look for Contact Display. Here you can select SIM Only or Phone Only, and if the number you want to use is missing from the list, it is in another storage.

It is important to remember that the contacts SIM-The map has severe limitations on the length of the name and the number of fields, so modern smartphones try to avoid using them for primary storage.

Default saving settings in MIUI and HyperOS

To avoid checking each new number manually, you need to set up automatic saving. Xiaomi allows you to choose a priority location for new entries. To do this, go to the Contacts app, open the settings menu and select Storage Settings or Preferred Save Place.

The list that opens will offer you a few options: Choosing the phone option means that all the data will be stored in the device’s internal memory, which is convenient but risky when resetting to factory settings, and choosing a Google account provides automatic synchronization and the ability to restore numbers on any device after logging in.

• 📱 Phone – data is stored locally, does not take up space in the cloud, does not require the Internet to access, but is lost when a breakage or reset.
• ☁️ Google Account is the perfect solution for most users, providing backup and synchronization between a smartphone, tablet and computer.
• 📶 SIM-Card is an outdated method that is compatible with all phones, but has limits on the length of the name and the absence of additional fields.
• 🌩️ Mi Cloud is Xiaomi’s proprietary cloud, convenient for those who are deeply integrated into the brand ecosystem, but less versatile when switching to Android from other manufacturers.

⚠️ Note: If you choose to save only on SIM-card, you will lose the ability to add photos, email addresses and additional phone numbers to contacts, since the chip memory structure does not support this.

It is recommended to install your Google account as the main storage location, which ensures that even if you lose your smartphone, your contacts will remain secure and automatically appear on the new device immediately after you log in.

Instructions for transferring contacts with SIM to the phone

If you find out that your numbers are on a SIM card, it is highly recommended to transfer them to internal memory or the cloud, this process takes only a couple of minutes and is performed through the built-in tools of the system without the need to install third-party software.

To start, open the Contacts app and find the menu button (usually three horizontal bars or dots). From the drop-down list, select Import and Export Contacts. The system will offer several options, among which we are interested in Import from the Internet. SIM-map».

Once you have selected the source, the system will ask where to save the data, and you can choose your phone or your Google account, and then you can list all the numbers available on the chip, and you can select individual records, or you can click "Select all" in the top corner of the screen, and then confirm the action with the "Import" button.

Path on the menu: Contacts → Menu (three dots) → Imports/Exports → Import with SIM-map → Select an account/phone → Choose all. → Imports

After the operation is completed, it is recommended to check the contact list again, filtering the display only for the purpose of the operation. SIM-If the list is empty, the transfer is successful, and now your data is protected from accidental loss when you replace the SIM.

Export and backup of data

Regular backup is a key skill for any smartphone user, and even if you store contacts in the cloud, having a local copy in.vcf format is never superfluous. This file can be sent to your mail, saved to your messenger or transferred to your computer.

To create a backup, go to Import and Export Contacts and select Export to Phone Memory or Export to Storage. The system will create a file containing all your records. The path to this file is usually specified in the notification or it can be found through the file manager in the MIUI/backup/contacts folder or simply at the root of internal memory.

Using a.vcf file is especially useful when switching to a different brand of phone or if you need to quickly restore the number base after flashing. Just transfer this file to a new device and launch it - the system will suggest importing the contacts contained inside.

Duplicate problems and solutions

Frequent situation after importation of SIM-You can have multiple accounts synchronized or mapped, duplicate accounts, and you can have the same person listed twice, once as "Ivan" with a different username. SIM-And the second time it's like a "Ivan Ivanov" with a Google photo, it not only clutters the address book, it also interferes with the correct operation of the number detector.

The MIUI shell has a built-in tool to combine records. In the Contacts app, click on the menu and select Contact Organization or Contact Management, and then Combine Duplicates. The system will automatically analyze the list, find matches by phone numbers or names, and suggest combining them into a single card.

• 🔍 Automatic merger – the system itself offers to combine similar records, you only need to confirm the action.
• ✋ Manual association – you choose two cards and click the “Unite” button, which allows you to control the process if the system is wrong.
• 🧹 Cleanup – After the merger, it is recommended to check the list for “empty” contacts without numbers, which sometimes remain after importation.

It's important to understand that when you combine data, the system stores all the information from both cards, so if you only had a number on SIM, and you only had a number on Google, a number, a mail, a photo, the final record is complete, but if the numbers were different, they'll both be saved in the contact fields.

⚠️ Warning: Before mass contact pooling, make sure you have a fresh backup. Misconception of different people with the same names can confuse the address book, and restoring the original state without a backup will be difficult.

Why you should not keep your contacts on SIM only

Keeping contacts exclusively on SIM-The card is now considered an archaic method that is being phased out by all manufacturers, including Xiaomi, mainly because of the chip's limited capacity and memory structure. UTF-8, Russian names can be displayed as a set of incomprehensible symbols.

In addition, the amount of memory SIM-It normally holds no more than 250 records, and if the contact name is long, the system may simply not let you save the number by giving a memory error. SIM-In an age where everyone has hundreds of contacts, this becomes a critical limitation.

💡

Expert advice: Use SIM-The card is only a temporary transport for transferring numbers from the old button phone. Immediately after transferring to a Xiaomi smartphone, copy the data to a Google account, and the very same card is used for the transfer of numbers. SIM-clear the map.

Another important aspect is physical binding: If you lose your SIM card or it fails, you lose all the numbers. Recovery of the SIM card from the operator usually gives you only your phone number for calls, but does not return the phone book recorded on the chip.
