Contact copying is one of the basic procedures that allows you to keep access to the numbers of friends and colleagues even in the event of loss or breakdown of the gadget. SIM-The card provides additional insurance.
The process of moving records in the MIUI shell has its own features, different from standard Android. The interface may seem overloaded, but the logic of actions remains consistent and clear. Exporting numbers will take only a few minutes, if you know which menu is hiding the desired feature.
Modern smartphones offer many synchronization options, including cloud services, but the old-fashioned method of porting to physical media is still relevant, especially for those who do not trust Internet storage or prefer to have a backup in their hands. Below we will discuss in detail the algorithm of actions that will suit most Xiaomi and Redmi models.
Preparation for data transfer and capacity check SIM-map
Before you start copying, you need to make sure that your SIM-Older SIM cards can have a limited amount of memory, which is often only 250 contacts. If your phone book has more records, then full transfer is physically impossible without first cleaning or selecting only selected numbers.
You should also pay attention to the format of the storage of names. SIM-There are often limits on the number of characters in the contact name, usually 14-16 Long names can be cropped, making it difficult to find the person on the list. Check if the SIM card is installed correctly, and the phone sees the operator's network.
- 📱 Make sure that SIM-The card is inserted into the correct slot if your Redmi has two.
- 🔍 Check the current number of saved numbers in your phone memory.
- 💾 Rate the free space on the SIM card through the contact settings menu.
- 🔋 Charge the device to minimum 30-40%, so that the process does not stop.
⚠️ Note: When copying contacts from phone to SIM-Old records already available on the SIM can be overwritten or deleted depending on the shell version MIUI. It is recommended to make a backup copy of the numbers on the SIM in advance if they are important.
Some carriers block the ability to write to a SIM card through software restrictions, although this is rare. If the copy menu is inactive, try re-inserting the SIM card or rebooting the smartphone, which will help the system read the parameters of the carrier again.
Use of the standard "Contacts" application in MIUI
The main tool for managing the phone book in Xiaomi smartphones is the built-in Contacts app. It is through this that most import and export operations are carried out. Open the application by finding it on your desktop or in the Tools folder. The interface may differ depending on the version of MIUI, but the basic functions remain available.
At the top of the screen, you'll usually have tabs or menu buttons, and you'll need to find the item that manages the list, and it's often hidden under a three-dot or gear icon, and you'll click on it and you'll see a drop-down menu with different options, including Import/Export contacts.

If you have two SIM cards on your phone, the system will ask you to choose which one to write numbers to, and be careful when choosing, because you can't change the target card during the copying process, and the data transfer process will begin after the confirmation.
Step-by-step: copying through system settings
An alternative and sometimes more reliable way to find the copy feature is through the general smartphone settings. This method is good because it bypasses possible bugs of a particular contact application. Go to the Settings of your Xiaomi or Redmi main menu.
In the settings list, look for a section that is related to the system or applications, and in different versions of the firmware, it can be called "Apps," "System Apps," or simply "Contacts." Once you go inside, you get access to advanced management of the phone book's functions.
☑️ Checklist before copying
Then the algorithm of actions repeats the work through the application: select the point of import / export and specify the source and recipient of the data. SIM-cards (such as photos or additional numbers).
| Parameter | Phone memory | SIM-map |
|---|---|---|
| Max. Number of contacts. | Depends on free memory (thousands) | Usually 250-500. |
| Length of name | No restrictions. | Up to 16 characters |
| Photo of contact | Supported | Not supported |

Working with two SIM-maps and the choice of target media
Redmi smartphones often feature two SIM card slots, which creates additional confusion when copying. SIM-map, the system should clearly understand which slot is meant. The dialog box usually displays operator names or tags. SIM 1 and SIM 2.
If you plan to transfer contacts to a new SIM card, insert it into your phone before the operation begins, which will avoid errors in choosing a non-existent carrier.

⚠️ Note: Format of storage of contacts on SIM-The card is unified and does not distinguish between "home", "worker" or "mobile" number type, all numbers will be recorded as normal voice calls, and if there are several numbers from one contact, only the first one will be copied.
In some cases, if one of the SIM cards is blocked PIN-In the code, the system may not offer it as a target device before unlocking. Enter the unlock code when you first start the phone after turning on to get full access to all contact management functions.
Possible problems and ways to solve them
Despite the simplicity of the procedure, users may encounter errors, often with overcrowded memory. SIM-In this case, the system will issue a warning and suggest that you choose contacts manually or refuse to copy, the solution will be to pre-clean the SIM card from old unnecessary records.
Another common problem is incompatibility of encoding or format: some contacts may contain characters or emoji in names that are not supported by the GSM standard.
What to do if the copy button is inactive?
Sometimes it can hang in the middle. Don't rush out the SIM card or reboot the phone, wait a few minutes. If progress doesn't move for more than 5-10 minutes, then you should interrupt the operation. Re-copying is better done in small groups of contacts.
