Owners of the popular smartphone Xiaomi Redmi Note 8 often face the need to transfer saved phone numbers from the internal memory of the device directly to the device. SIM-This is usually required when you change a gadget to another manufacturer that can't import data from Google's cloud services, or when you go back to using button phones. In the Android ecosystem, and especially in the shell. MIUI, By default, all new records are saved to a Google account or device memory, which creates the illusion that they cannot be moved quickly.
Contact management system in Redmi Note 8 It has hidden export functions that circumvent standard restrictions, and it doesn't require third-party apps or root rights, it's done with the operating system's regular tools. SIM-The card has limited capacity and often trims long contact names before the 10-15 symbols, so before mass transfer it is worth weighing all the pros and cons.
In this article, we will discuss in detail the algorithm for safely copying a phone book, learn about the nuances of the MIUI interface, possible errors in export and how to fix them, and follow the sequence of steps ensures that your entire address book is safe without losing important numbers.
Preparation of SIM-card and compatibility check
Before you start manipulating data, you need to make sure that you can write to your SIM card.Some old or stripped down carrier cards may have a limit on the number of records or do not support the encoding of names in a certain format.
Go to your phone settings and check the status. SIM-If a card is new or has been used in devices with a different file system, it may need to be formatted, but remember that this will delete all the numbers already on it.
It is also worth noting that the Redmi Note 8 supports the work of two SIM-You'll have to choose which one to use (SIM 1 SIM 2) a copy will be made if both are active. Make sure the card selected is not blocked PIN-code you don’t remember, otherwise the process may be interrupted at the confirmation stage.
⚠️ Note: Before starting any contact transactions, it is strongly recommended to back them up in the Google cloud or export them to a.vcf file. This will protect you from accidental data loss in the event of a system failure or user error.
Check the space available on the SIM card. Standard capacity varies from 250 to 500 numbers depending on the type of card. If your phone book is much larger, you will have to choose only the most important contacts or use the method of selective copying.
Access to contact management in MIUI
The MIUI shell interface on the Redmi Note 8 is different from standard Android, which can confuse a beginner. To get started, open the standard Contacts app, which has a green icon with a human silhouette, and that's where all the tools for working with the phone book are concentrated.
At the top of the screen, you'll see three tabs: Favorites, Contacts, and Groups. We're interested in the central tab. In the upper right corner or at the bottom of the screen (depending on the firmware version), there's a three-dot menu or a "More" button, and clicking on this item opens a hidden action menu.
In the list that opens, you need to find Settings or Import and Export. In some versions of MIUI, this item is placed separately. If you don't see the option you want, try pulling the contact list down, sometimes the control features appear in the drop-down menu.
The key is to choose the source of the data, the system needs to understand where we're going to copy the numbers, the default can be to choose the display of all the contacts, including those in messengers or social networks, and we need to make sure that the source is the phone or the device where the basic data is stored.
💡
If the item “Import and export” does not appear, try to switch the view of the display contacts to “All contacts” or “Device” rather than “Device «SIM-map».
Process of exporting contacts to SIM-card
After entering the "Import and export" menu, you will see a list of available operations. SIM-card (or "copy from phone to phone"); SIM»). Selection of this item starts the process of preparing data for transfer.
The system will suggest selecting contacts to transfer. You can mark specific numbers manually or use the "Select All" function. When selecting all contacts, the Xiaomi Redmi Note 8 can warn that not all records will fit on the card due to the limitations of the SIM card memory.
Once the selection is confirmed, the copying process will begin, a progress bar will appear on the screen displaying the status of the operation, at which time it is not recommended to turn off the screen or switch to other applications so as not to interrupt the recording of data in the card chip.
☑️ Export algorithm
When the process is complete, the system will issue a successful copy notification or report errors if some contacts are not recorded, most often due to too long names or the absence of a phone number field in the contact card.
Format limitations and name cropping
One of the main problems in transferring data to SIM-The card is an outdated standard for storing information. Unlike cloud services or smartphone memory, the SIM card has strict limits on the length of the line of the contact name.
Usually, the name is trimmed to 10-15 characters in Latin or even less in Cyrillic, which means that the contact "Alexander Pushkin" on the SIM card can turn into "Alexander Serg", and additional fields such as email address, photo, second phone number and address can also be lost.
Also, there are often encoding problems: Cyrillic names can turn into a set of obscure characters or question marks after transfer, especially if the receiving device has a different regional standard. To avoid this, some users pre-transliterate the names, but it is time consuming.
| Parameter | Phone Memory/Google | SIM-map |
|---|---|---|
| Maximum length of name | Limited only by common sense. | 10-15 characters |
| Number of rooms | A few to contact. | Usually one. |
| Photo of contact | Supported | Not supported |
| Additional fields (Email, address) | Supported | Not supported. |

Solving Common Problems When Copying
When transferring contacts to Xiaomi Redmi Note 8 users may encounter the message “Memory” SIM-The card is full, even if the card is empty, and this is a well-known software error where the system misreads the free space, and the solution is to clear the card of old records through the control menu. SIM.
Another common problem is that the Copy button is inactive or the process is stalled. In this case, try rebooting your smartphone with your SIM card installed. Also, cleaning the Contacts app cache through the phone's settings menu: Settings → Apps → All Apps → Contacts → Memory → Clear the cache helps.
If the contacts are copied but without names (numbers only), check the format of the save. In some cases, changing the system's language to English before export, performing the operation and returning Russian helps, although this is rarely required in modern versions of MIUI.
⚠️ Attention: Don't pull out SIM-Give the system a few seconds to complete the background recording processes to avoid damaging the card file table.
If standard means of transferring contacts fail, you can use an intermediate format: export contacts to.vcf file to internal memory, and then use third-party utilities to write this file to the SIM card, although this is a less reliable method.
Alternative methods of data retention
Given the limitations of SIM cards, experts recommend using more modern methods of transferring the phone book. The most reliable way for Android owners is to sync with a Google account. When you log in to a new phone, just enter a username and password, and all contacts will be restored automatically.
To switch to iPhone or other platforms, you should use the.vcf file. From the “Import and Export” menu, select “Export to internal memory” or “Export to storage.” The resulting file can be sent to yourself by email or messenger and opened on any device.
There are also specialized apps from the Google Play store, such as "Copy My Data" or "Move to iOS," that transfer contacts over Wi-Fi, which save photos, extra numbers and long names that a SIM card can't.
💡
A SIM card is an outdated contact medium. Use Google cloud sync or export to.vcf to securely store your data.
If the use of the SIM card is dictated by necessity (for example, a very old phone), then after transfer, be sure to check the result by flipping through the list of numbers directly in the menu. SIM-maps, not a general contact list.
