Xiaomi, Redmi and Poco smartphone owners often face the need to move the phone book to a new one. SIM-This may be due to a change of carrier, switching to a different tariff plan or a banal desire to keep important numbers in the operator's cloud in case of loss of the device. MIUI HyperOS is not always obvious to users who are used to other interfaces.
Modern Android operating systems are looking to move away from storing data on plastic media by offering synchronization via a Google account. SIM-The card remains a universal and Internet-independent storage. In this article, we will discuss in detail how to perform the transfer, what are the nuances of working with.vcf files and what to do if the standard function in the menu is hidden by the manufacturer.
Why you need to copy contacts to SIM-card
Storing numbers directly on the chip SIM-There are a number of advantages to having a card, especially when you're connected to a messy Internet connection or when you're changing gadgets a lot, and the main advantage is that you don't have to type in a Google login or a Mi Account on someone else's phone to access a call list. Simply insert the card into any device and the numbers will be available.
It is also a great way to back up before resetting your Hard Reset settings.If you plan to reflash or sell your device, copy it to the factory. SIM This is the last frontier of data loss protection. SIM-The card has limited memory and field formatting, but for base numbers it is ideal.
💡
When transferring to SIM, only the name and number are saved, and photos, email addresses and additional numbers will be lost.
Another important aspect is compatibility: Older push-button phones or simple office phones may not be able to sync through the cloud, and in these situations, an Android smartphone acts as a converter, rewriting data from digital format to the standard GSM card protocol.
Preparation of SIM-card and memory check
Before you start taking action, you need to make sure that your SIM-Older Mini-SIM cards or damaged chips may have little memory or read error. Modern Nano-SIM cards typically hold 250 to 500 entries, but the limit can vary depending on the operator.
If you already have old numbers on it, the copying process can be interrupted in the middle, leading to chaos in the phone book, clear out excess records or delete duplicates through the contact management menu on any device.
☑️ Pre-transfer check
It is also worth paying attention to the encoding of names. SIM-The cards often use outdated encoding, which may cause Russian letters to appear as question marks or Krakozyabr on some devices. If you’re critical to getting names right on older phones, it might be worth transliterating them or using the Latin alphabet, although modern Xiaomi smartphones usually handle conversions automatically.
The standard way through the contact menu
In most cases, the MIUI shell allows you to carry out the transfer with normal means without installing third-party software. You need to open the standard Contacts or Phone application and go to the settings. The interface may vary slightly depending on the firmware version, but the logic remains the same.
Follow the step-by-step instructions:
1. Open the Contacts app.
2. Press the three dots in the corner of the screen or the Settings button.
3. Select the item Import / Export contacts.
4.Push the Export button on SIM-map.
⚠️ Note: If the item "Export to" SIM-The map is not on the menu, which means that the manufacturer has restricted this feature in your firmware version.
Once you select a source (usually a phone or a Google), the system will suggest that you mark the contacts to be transferred, you can select all of them at once, or you can check them manually, and you can confirm the action, and the copying process begins. The latency depends on the number of records and the speed of the device's memory.
When the process is complete, the system will issue a notification of successful copying. SIM-card and insert it into another phone (or the same one, changing the display of contacts to SIM), It'll take a few minutes, but it'll save you from some nasty surprises in the future.
Use Google Contacts for Intermediate Exports
If direct exporting doesn’t work or you want to do more subtle filtering, Google’s services are a good option, especially if you need to pre-clean the list of duplicates or sort numbers. Google’s cloud synchronization is the gold standard for the Android ecosystem.
The algorithm of actions is as follows:
1. Make sure that contacts are synced with your Google account.
2. Go to the contact settings and select “Import/Export”.
3. Select the option Export to file.vcf (or Export to internal memory).
4. Save the file on the device.
The resulting contacts.vcf file contains your entire phone book in a universal format, and then you need to import it back, but you have to choose not internal memory, but instead the target. SIM-In some versions, some versions. MIUI This pathway is the only working way to activate the hidden recording function on the chip.
| Parameter | Direct exports | Through file.vcf | Through Google Cloud |
|---|---|---|---|
| Speed. | Tall. | Medium | Depends on the network. |
| Photo preservation | No. | No (when exported to SIM) | Yes. |
| Risk of loss | Low. | Medium (file) | Minimum |
| Difficulty | Low. | Medium | Tall. |
Bypassing restrictions: if the export button is hidden
In newer versions of the HyperOS shell and some regional MIUI firmware, the SIM export function can be removed completely from the interface, which is done to promote cloud services, but becomes a problem for the user, and can be solved using third-party converter applications available on Google Play.
One of the reliable solutions is the "Copy to SIM Card" app, or high-rated analogues, which have direct access to the telephony API and can force data to be written to a chip, ignoring the system's limitations, download the application, grant the necessary permissions to access contacts, and follow the instructions inside the program.
Why is Xiaomi hiding this feature?
Sometimes, changing your phone settings helps, if you're in a region where features are cut, switching to India or Nepal (temporarily) can bring back full functionality to the contact menu, and remember to bring back your region settings after you've done the operation to keep local services and weather working properly.
Possible problems and solutions
Users often experience errors during the transfer process. The most common is "Memory". SIM-This is solved only by manually cleaning the card through the control menu. SIM. Another common problem is the circumcision of long names. SIM limitedly 14-20 So, "Alexander" can become "Alexander Mob" and long composite names will be cut off.
There may also be a format error: International numbers written with a plus (+7...) may not read correctly on some older devices, in which case manual editing of the dial format may be required after the transfer. If the process freezes, try restarting the smartphone and repeating the operation, pre-close all background applications.
⚠️ Attention: Don't pull out SIM-This can damage the file system of the card and completely lose all contacts already recorded on it.
If none of the software methods help, perhaps it will. SIM-The card is physically damaged or has an older memory standard, so the only way out is to replace the card with the carrier and save the number, which will solve the compatibility problem.
💡
If Xiaomi’s built-in tools don’t work, use proven apps from the Play Market like Copy to SIM Card, which is the quickest way to get around system limitations.
