How to transfer phone numbers from phone to phone SIM-Xiaomi

Changing your smartphone or having to restore access to your contact database often puts users in the position of migrating numbers to a physical medium. In Xiaomi’s MIUI ecosystem, this process has its own peculiarities that differ from standard Android. Many users mistakenly believe that it is enough to copy data, but there are nuances of encoding and memory limits of the chip.

Before starting the procedure, it is important to understand that the SIM card is an outdated carrier with disabilities. It is not designed to store large amounts of information, such as photos, email addresses or multiple numbers for a single contact. However, as a backup method or a way to quickly migrate to a button phone, this solution remains relevant. Below we will discuss all the available methods and potential complications.

The main purpose of this operation is to ensure the safety of your data when you reset or break the device. SIM-As a temporary buffer, you can avoid losing your critical numbers. Let’s take a closer look at the algorithm for different Xiaomi smartphone use cases.

Preparation of the device and compatibility check

Before you start copying, you need to make sure your SIM card is technically sound and correctly installed in the slot. Modern Xiaomi smartphones often use combined trays, so make sure the card sits tightly and is determined by the system. Go to Settings → About phone → General details to check the status of the connection.

An important step is to clear the memory of the SIM card itself of old records, if any. The storage limit on the chip is often as low as 250 or 500 records, and new numbers may simply not be saved if space is occupied.

⚠️ Note: When copying contacts from phone to SIM-The card is often cropped with the contact name before 10-15 It's a technical limitation of the format of the data storage on the chip, not a system error.

It is recommended to back up your current contacts in the Google or Mi Cloud cloud in advance, which will protect you from accidental data loss in the event of a software failure during the transfer procedure.

• 📱 Make sure that the SIM card is inserted into the correct slot (usually Slot 1).
• 🔋 Charge the device to at least 40% to avoid sudden shutdown.
• 📶 Check the availability of the network signal for the correct operation of the communication module.

Standard method of copying through the Contacts application

The easiest and fastest way to move numbers is to use Xiaomi's built-in Contacts app.The interface may vary slightly depending on the MIUI version, but the logic of the action remains the same. Open the app, which usually has a green icon with a human silhouette.

In the list that opens, find the menu button, which can be located in the top right corner (three dots) or hidden in the sidebar. You need to select Import and Export contacts. This is where all the phone book management tools are concentrated.

💡

If you don’t see the item “Import and Export”, try clicking on the three dots in the corner of the screen or swipe left to right to call the side menu.

Once the source and the recipient are selected, the system will request confirmation of the operation. Click Copy or OK to start the process. The run time depends on the number of records: moving 100 numbers will take a few seconds, whereas 1,000 can take longer.

Some firmware versions may require you to choose which contacts to copy, all at once or only a select few. If you choose selective copying, be careful not to miss important numbers. The "Select all" checkbox speeds up the process significantly.

• ✅ Open the Contacts app on the home screen.
• ✅ Go to the settings menu through three dots or swipe.
• ✅ Select "Import and export contacts" →"Exports to SIM-map".

Using the settings menu of the Android system

If the contacts are not copied or the interface is changed, you can use the system settings of Android itself, which is considered more reliable, since it addresses directly to the system data store, bypassing possible bugs of the MIUI shell.

Go to the main smartphone settings menu and find the Apps section. In the list of installed programs, look for Contacts or Contact Management. Depending on the Xiaomi model (Redmi or Mi), the path may vary slightly, but the essence remains the same.

Inside the contact management menu, select the option to copy contacts. The system will prompt you to select a source (Phone, Google, Mi Account) and a destination (SIM-This method is especially useful if the standard application is not stable.

After the process is complete, the system will issue a notification of successful copying or report errors if some numbers cannot be recorded, and it is recommended to immediately check the result by opening the phone book from the selected SIM card.

Working with multiple SIM cards

Xiaomi smartphone owners often use two SIM cards at the same time. When transferring contacts, the system will ask which card to save data to. Be careful when choosing to avoid confusing work and personal SIM cards.

If you have to copy contacts to both cards, you have to do it twice, so you first pick the first SIM card as the recipient, you wait until you finish, and then you repeat the operation for the second one. There is no automatic two card allocation.

When exported to two different cards, contact names can be duplicated unless you sort them in advance, which can lead to confusion when calling the same caller will be displayed twice from different numbers.

• 1️⃣ Insert both SIM cards into the corresponding slots of the device.
• 2️⃣ When selecting the recipient, indicate"SIM 1" for the first batch of numbers.
• 3️⃣ Repeat the procedure by selecting"SIM 2" for the remaining records.

Alternative Ways and Cloud Services

Modern technology offers more flexibility than physical copying, and Google Contacts allows you to synchronize data between any number of devices without using a SIM card, the most convenient way for those who often change gadgets.

To use this method, you just need to log into your Google account on a new phone, and all the numbers stored in the cloud will automatically appear in the phone book, eliminating the risk of data loss if the physical media breaks.

You can also use MI Mover to quickly transfer data from your old phone to your new Xiaomi, which transmits contacts, messages, photos and settings over Wi-Fi Direct, which is much faster and more reliable than writing to a SIM card.

⚠️ Note: When using cloud services, make sure you have a stable Internet connection. Interrupting sync may cause some contacts to not load onto the device.

If you still prefer local storage, you can export contacts to a.vcf file and save it to your phone’s memory or memory card, and then import it to any other vCard-enabled device.

Solving problems and errors when copying

One of the most common problems is to report that the SIM card memory is full, in which case you need to delete some old or unnecessary entries directly from the card, and you can do this through the contact management menu by selecting the "Show Only Contacts with SIM" filter.

Another common difficulty is that contacts are copied but not displayed in the call list. Check the display settings in the Contacts app. Often the default is the Phone Only filter, and you need to manually enable the SIM card contact display.

If the copying process freezes or ends in an error, try restarting your smartphone. Temporary system files may have blocked access to the recording module.

In rare cases, the problem lies in the number format. Some older SIM cards do not support the international format with a plus (+7), requiring the deletion of the country code.

Comparison of methods of storing contact data

To understand the advantages and disadvantages of different ways of storing numbers, consider a comparison table, which will help you choose the best option for your situation.

As you can see from the table, the SIM card is the least functional medium, and it is only justified in extreme cases or for very old models of phones that do not support synchronization.

💡

The best practice is to store contacts in a Google account, as this ensures they are safe and accessible from any device, regardless of the physical SIM card.
