Transfer of contacts to SIM-map in Xiaomi smartphones

Possession of a modern smartphone implies the constant use of digital services, but basic communication functions remain the foundation of interaction. Many users of Xiaomi, Redmi and Poco devices are faced with the need to transfer the accumulated number base from internal memory to physical memory. SIM-This may be required when changing devices, resetting to factory settings, or simply creating a physical backup in the era of cloud storage.

The process of moving data seems trivial, but the interface of the MIUI shell or HyperOS has its own features that can confuse the inexperienced user. Often the menu is hidden in non-obvious sections, and standard actions are blocked by the system limitations of Android. In this article, we will discuss in detail the algorithm of actions that is guaranteed to help you maintain important connections.

Before you start manipulating a database, you need to be aware of the difference between storage formats. The internal memory of a phone allows you to save numbers with long names, add photos, email addresses, and link numbers to instant messengers. SIM-A map is a technology of the past that has very limited character size in a contact name and number of records, and understanding these differences will help avoid losing important information during the transfer process.

Preparation for the data export procedure

The first step before any major data operation is to check the physical condition of the host. SIM-The card is correctly identified by the system and displayed in the status bar. If you just inserted a new chip, wait for the network to appear before you switch to contact management. An unstable connection can lead to an error in the recording.

The second important aspect is analyzing the current status of the contact list: often duplicates, old entries and “junk” from remote applications accumulate in the memory of the smartphone. Duplicate records can lead to the fact that when exported to a SIM card, which has a limited amount of memory, the process will be interrupted halfway, it is recommended to pre-clean the list.

⚠️ Note: Before starting a mass transfer, we strongly advise you to back up your contacts to your Google account, which is insurance in case the process goes wrong and the data is damaged or lost.

It is also worth checking if you are not overcrowded. SIM-Older cards often have a limit of 250 contacts, and if you have thousands of numbers, you can't physically transfer them without losing some of the data, so you'd better choose only the most important numbers or use cloud services.

Standard method through the Contacts app

The easiest and most reliable way to transfer numbers on Xiaomi devices is to use the built-in system application. It already has all the necessary access rights and does not require the installation of third-party software. Open the Contacts app (an icon with a human silhouette) on the home screen or in the Tools folder.

In the application interface, you need to find the settings menu. Depending on the version of the MIUI shell, it can be located in the upper right corner (three dots or three stripes) or caused by long clicking on the empty place of the list. Find the item Import / Export contacts. This is where the feature is located.

After selecting an export point, the system will offer you two options: export to internal memory (creating a file.vcf) or export to the local storage. SIM-You pick the second option. The system will alert you that the format is SIM-The card does not support some fields, such as photos or long addresses.

• 📱 Open the Contacts app on the desktop.
• ⚙️ Click on the settings menu (three dots in the corner of the screen).
• 📤 Choose the Import/Export Contact option.
• 💾 Press the Export button on SIM-map.

Then the phone will suggest you select the contacts to transfer, you can mark specific numbers manually or select the option "Select all." Once confirmed, the copying process will begin. The speed depends on the number of records, but usually it takes no more than a minute.

Use of the SIM-card management menu

In some versions of HyperOS firmware or custom builds, the path through the contact app may be different. An alternative method lies through the system settings of Android itself. This method is especially useful if the contact app is not working correctly or “drops out” when trying to export.

Go to Settings on your smartphone, then select SIM cards and mobile networks. Here you can see the information about the connected carriers. SIM-The card you plan to write numbers to if you have a device with two slots.

In the menu of the selected SIM card, find the Contacts item on SIM-map or contact management SIM. Clicking on it will take you to a utility menu where the import button will be available, which will bypass unnecessary interfaces and work directly with the communication module.

And using this method, you get a more technical interface that looks simpler, but it does the same function, and it's convenient because it shows you how many contacts are already on the map and how many are free.

Format limitations and technical nuances

When transferring data, it is important to understand the technical limitations of the storage format on the SIM chip. It is not a full-fledged database, but a simplified file system. The limit of the characters in the contact name is usually from 10 to 14 characters (depending on the encoding of GSM 7-bit or UCS2). If the name "Alexander Vladimirovich" is shortened to "Alexander Vlad" when exported, do not be surprised - this is the standard behavior of the technology.

Besides, SIM-The card doesn't store any extra fields, all email addresses, social media links, company addresses and, most importantly, contact photos will be permanently lost on the transfer, leaving only the name and the primary phone number. That is why a full backup for SIM today is considered an archaic method.

⚠️ Note: When exporting contacts with Russian names in old ones SIM-And there's a pattern distortion that can occur in the cards, and instead of letters, there's a question mark or a crankshade, and this is because of Unicode on old carrier chips.

Another nuance is the division of memory. SIM-Contacts are often divided into groups (e.g., voice only) and some phones may ignore numbers marked as fax or modem when trying to record them.

💡

Keep your contacts in your Google account, not on your account. SIM-This will allow you to automatically restore the phone book when you change your smartphone, tablet or even switch to the iPhone without losing photos and additional numbers.

Solution: errors and duplicates

Users often face a situation where, after exporting to the SIM-You get duplicates of the same subscribers, and this happens if you've already saved copies of those numbers in your phone's memory, and you just add new fields to your existing record.

To solve the problem, use the unification function. In the Contacts app, click three points, select Contact Organization (or Management) and find Combine Duplicates. The system will find the matches by phone number and name, suggesting that they be merged into a single card.

If the export process is interrupted with an error "Memory" SIM-You have to delete some of the less important numbers directly from the SIM card. SIM-Select unnecessary entries and press the delete button (basket icon).

• 🧹 Use the "Combine Duplicates" function before exporting.
• 🗑️ Clean it up. SIM-map.
• ✂️ Export contacts in small groups (by 50-100 piece).
• 🔄 Check the encoding of names after the transfer.

There is also an error when the phone says, "No contact was made," which often happens if the contact name contains forbidden characters or is too long. Try renaming the problem contact by reducing the name to 10 characters, and try again.

💡

The most common reason for poor exports is overflowing memory. SIM-maps or duplicates in the original contact list. Always start by cleaning and combining records.

Alternative Ways and Cloud Services

In the digital age, moving contacts to a plastic card is not the only option, and often not the best option: Xiaomi owners can use sync with a Mi Account or Google account, which allows you to instantly transfer the entire phone book to a new phone just by entering a username and password.

To do this, go to Settings → Mi Account → Sync and make sure that the slider opposite the Contacts item is active. The same can be done through Google settings (Accounts → Google → Sync). Once enabled, the data will automatically fly to the cloud.

If you need to physically transfer data to another phone without the Internet, you can use the export to the file.vcf. Select the contact menu "Export to internal memory." The resulting file can be transferred via Bluetooth, Mi Drop or sent to the messenger and then opened on the new device.

⚠️ Note: The file.vcf stored in internal memory will be deleted when the phone is reset to the factory settings (Hard Reset). Immediately after creating a copy, move the file to the computer or to the cloud storage.

Using cloud technology eliminates encoding, character limits, and memory problems, and you can store thousands of contacts with full profiles that can be accessed from any device in the world with the Internet.
