Many users who switch from button phones or other Android models often wonder how to transfer contacts to a SIM card in the Xiaomi Redmi Note 8T. This procedure seems obvious, but in modern versions of the MIUI shell and the Android operating system, engineers from Google and Xiaomi have made significant changes in the logic of working with the address book. The standard interface no longer offers the usual “copy” button as it was in older versions of firmware, which causes confusion among smartphone owners.
The situation is complicated by the fact that SIM-The card has a very limited amount of memory and is technically not able to store all the information we are used to seeing in contacts: photos, multiple numbers, email addresses and social networks. That is why the default system suggests storing data in the cloud or internal memory of the device, but the need for physical transfer has not gone away, especially when changing carriers or switching to a button phone.
In this guide, we will take a look at all the ways to import and export numbers, and explain why some of them are hidden from the eyes of the average user. You will learn about the technical nuances of the Redmi Note 8T file system and understand how to safely manage your phone book without losing important data. We will look at both regular tools and specialized utilities that will help solve the problem even in the most difficult cases.
Technical limitations SIM-maps and storage format
Before we take action, we need to understand the fundamental differences between today’s digital contacts and the outdated SIM-based storage format. The SIM-card file system was developed decades ago, when the primary requirement was the ability to store a subscriber’s name and a single phone number. Modern smartphones, including the Xiaomi Redmi Note 8T, operate with much more complex data structures.
When you try to keep a SIM contact, the process of truncating information takes place: the long name will be cropped, the second phone number will disappear, and all additional fields, such as a job title or address, will be ignored by the system. Moreover, the encoding of text on the SIM card often does not support the Cyrillic alphabet in the way we are used to seeing it, which can lead to the appearance of “crackers” instead of names when transferred to another phone.
⚠️ Note: Before mass export, it is strongly recommended to back up contacts in a Google account, as the process of writing to a SIM card is irreversible in terms of losing additional fields of information.
There is also a limit on the number of characters in a name, which is usually no more than 10-15 characters. If your phone book has contacts with full names and patronymics, they can turn into a set of letters on the SIM card, which is why importing with SIM is often a safer and more common operation than exporting to it.
Why is Xiaomi hiding its export function?
Standard method through the Contacts app
In most cases, users search for the port function directly in the standard application, which is preinstalled on the Redmi Note 8T. The interface of the program may vary depending on the version of MIUI, but the basic logic remains unchanged. First, you need to open the Contacts app and go to the settings, which are usually hidden under the menu button or three dots in the corner of the screen.
In the settings menu, you should find the item "Import and export contacts", and here the system will offer several options for you. If you want to copy numbers from the SIM card to the memory of your phone, select the appropriate item. The system automatically reads all the records and prompts you to save them to the internal memory of the device or immediately to the Google account.
- 📱 Open the Contacts app on the home screen.
- ⚙️ Click on three dots or the menu button to call for additional options.
- 📥 Select "Import and Export Contacts" in the drop-down list.
- 💾 Click "Import with" SIM-card for transferring numbers to the phone.
However, if your goal is to reverse the action of moving contacts to the SIM card, you may encounter a problem. MIUI For the Redmi Note 8T "Export to" button SIM-This is done deliberately, because the developers think this method is outdated, and then the standard application will not help, and you will have to resort to third-party solutions or hidden engineering menus.
💡
Use the “Joint Repetitive Contacts” function before exporting to avoid clogging the SIM card memory with duplicate records.
Use of third-party applications for export
Because Xiaomi’s regular funds often make it impossible to export, specialized applications from the Google Play store come to the rescue, these utilities have the necessary system permissions to access the contact database and can forcibly write information to the SIM card chip, ignoring the limitations of the MIUI interface.
One of the most popular and proven solutions is the application "Copy My Data" or specialized managers. SIM-Once you install this app, you'll need to give it access to contacts and a phone book, and it'll scan the database and ask you to select numbers to move.
The recording process is slow because the SIM card has a low data rate. Do not interrupt the process or turn off the smartphone screen during the operation. Once completed, it is recommended to check the result by calling from another phone to your number and making sure that the name is correctly determined.
| Annex | Type of access | Cyrillic support | Convenience |
|---|---|---|---|
| SIM Card Manager | Hand-held | Partial | High. |
| Copy My Data | Automatic. | Complete. | Average. |
| Contacts+ (Export) | Hybrid | Complete. | High. |
| MIUI Contacts | Systemic | Complete. | Low (no exports) |
Always check the developer rating and other users' reviews before installing your personal data, and the security of your personal data depends on the reputation of the software creator.
Working with Google Accounts as an Alternative
The most reliable and modern way to transfer contacts for owners of Redmi Note 8T is using the Google ecosystem, which does not require physical interaction with the SIM card and allows you to save the full information: photos, additional numbers, addresses and notes.
To set up sync, go to your smartphone settings and find Accounts and Sync. Select your Google account and make sure the switch opposite Contacts is activated. The system automatically uploads all numbers to the cloud, where they can be restored to any other device by simply entering your login and password.
If you need to transfer contacts to another phone that is not a smartphone or has no Internet access, you can use the export function to the VCF file. This file can be transferred via Bluetooth, messenger or saved to a memory card. On the receiving device, just open this file and all contacts will be added to the phone book.
⚠️ Note: When exporting to the file VCF Make sure you select vCard 3.0 or higher to correctly display Cyrillic names and special characters on devices from different manufacturers.
Using cloud technology eliminates the risk of data loss when a SIM card is physically damaged or lost. Unlike a SIM card chip, which is easily damaged or lost, data in a Google account is protected by multi-factor authentication and is accessible from anywhere in the world.
💡
Google Account is the only way to keep a full contact structure (photo, email, multiple numbers) without losing your device.
Hidden Opportunities and Engineering Menu
For advanced users who are not afraid to experiment with system settings, there is access to Xiaomi’s hidden engineering menu.This interface is designed to test hardware by developers, but contains management functions. SIM-This menu is accessed through a special code set in the "Phone" application".
Type ##4636## in dialer-e. If the code is active for your firmware version, the Testing menu will open. Here you should select "Phone information." In some versions of Android, you can find the "Update phonebook from SIM" or similar options button here, but the functionality may vary.
adb shell pm grant com.android.contacts android.permission.WRITE_CONTACTSA more sophisticated but effective method involves using ADB (Android Debug Bridge) from a computer. By connecting the Redmi Note 8T to a PC in debugging mode, you can force a database of contacts. However, this method requires root rights or special permissions obtained through ADB, and is not recommended for ordinary users because of the risk of system disruption.
- 🔧 Turn on the developer mode by seven times clicking on the build number in About Phone".
- 💻 Activate "Debugging by" USB" developer menu.
- 🖥️ Connect your phone to your computer and use commands ADB database management.
- ⚠️ Beware: Incorrect commands can lead to resets or data loss.
Using an engineering menu is a last resort, and 95% of the time, it's enough to use standard contactor apps from Google Play that do the same thing, but with a friendlier interface and less risk to the system.
Frequent problems and ways to solve them
During the process of transferring contacts, users of Xiaomi Redmi Note 8T can face a number of typical problems, most often when after exporting the names are displayed as a set of numbers or incomprehensible characters, this is due to the difference in encoding between the smartphone operating system and the SIM card chip.
Another common problem is limiting the number of contacts: old SIM cards can store no more than 250 records, if you try to move more numbers, the process will stop or new entries will overwrite old ones, in which case you either need to delete some contacts or replace the SIM card with a new one from the carrier.
⚠️ Note: If contact photos are missing after transfer, don't panic. The SIM card doesn't technically support image storage. The photos will remain in your phone's or Google account's memory unless you select Copy and Move".
There may also be a memory error. SIM-The card is full, even if you carry a few contacts, and this is treated by completely clearing the SIM card through the contact management menu. SIM", Confirm the action and then re-start the export procedure.
