Owning a modern smartphone Xiaomi implies constant work with a huge amount of data, among which the phone book occupies one of the key places. Changing a device or switching to another operating system often puts the user in front of the need to quickly transfer records, and the most universal, albeit somewhat outdated method, is the use of the system. SIM-This method allows you to save numbers even in the event of complete loss of access to cloud services or damage to the internal memory of the gadget.
The process of transferring the shells of MIUI and the new HyperOS has its own features, which are important to consider for the correct display of information. Unlike older button phones, modern smartphones limit the amount of data that can be stored by the operator chip, so it is important to understand the technical details of the procedure. Below we will discuss in detail the algorithm of actions that will help you safely and efficiently transfer all the necessary numbers.
Technical limitations and storage features
Before taking action, it is important to be aware of the architectural limitations of technology. SIM-Unlike cloud storage or smartphone internal memory, the carrier chip uses a file system developed decades ago, when the main recording parameter was only a phone number. Modern Xiaomi smartphones store many additional fields to each contact: e-mail address, home and work address, several numbers, photos, links to social networks and (notes).
When you copy to a map, you inevitably convert data, and most of that additional information is lost, and the technical limit is usually about 250 characters per contact name, and sometimes less, depending on the card firmware, which means that long composite names can be cut off, and fields like "Organization" or "Office" will simply disappear.
β οΈ Note: When transferring contacts from phone to phone SIM-All additional fields (email, addresses, second numbers) will be deleted, only the main name and one primary phone number will be retained.
You also have to consider the difference in encoding. If you use Cyrillic names, some of the old ones. SIM-Maps or then inserted into phones of other brands (for example, old Nokia or Sony Ericsson models) can be observed βhot-hairβ β displaying text in the form of incomprehensible characters. Modern Xiaomi devices usually correctly process the encoding UTF-8 or GSM 7-bit, But the risk of incompatibility when switching to very ancient gadgets remains.
Another important aspect is the separation of memory. SIM-If your phone book has a few thousand contacts, you can't physically put them all on the operator's chip, and the system will suggest moving only a fraction of the records, or interrupt the process when the space is gone. This method is ideal for backing up the most important contact kernel, but is not suitable for a full backup of the entire digital life of the user.
Preparation of the telephone book for transfer
To successfully perform a copy operation, you need to pre-prepare a contact list in the Contacts app from Xiaomi or Google. Often the numbers are stored in different sources: part in a Google account, part in the phone memory, and some records can be duplicated. Before starting work, it is recommended to conduct an audit so as not to waste time on transferring junk data.
Open the standard Contacts app and go to edit or view all lists. You need to make sure that the contact selected for export is in the correct number format. The system may not allow you to copy the entry if the number field shows text or characters that are not supported by ITU-T E.164. Also check if important contacts are hidden by display filters.
If you're planning to move a large group of people at once, it makes sense to combine the duplicates in advance. MIUI There's a Repetitive Contacts Unit feature that automatically finds the same number or name and merges it into a single card, which not only cleans the list, but also saves precious space. SIM-a card, because one record will take one cell instead of two or three.
An important stage of preparation is to check the available space on the most SIM-Although modern chips are roomy enough, if the card is very old (issued) 10-15 It can be filled with residual data from previous devices, and ideally, before mass copying begins, you should delete old, already irrelevant records directly from the computer. SIM-Maps via the Contact Management Menu.
Step-by-step instructions for copying contacts
Transfer of data to SIM-The map in Xiaomi smartphones is standardized, but the path to the desired function may vary slightly depending on the version of the shell. Below is a universal instruction, relevant to most models, including the Redmi Note series and the flagship Mi Mi.
To start, open the Contacts app. In the upper right corner of the screen (or in the lower corner, depending on the navigation settings), find a three-dot icon or gear, which is the settings menu. When you click on it, you'll see a list of available transactions. We're interested in an item that could be called Import and Export Contacts or simply Export.
βοΈ Checklist before copying
In the export menu, the system will suggest you select a data source. Usually the default is "Device Memory" or "Google Account." Select the desired source if you have multiple. Next, a list of available destinations will appear. SIM-map or copy SIM-If you have two cards. SIM-The system will ask you to specify which one of them (SIM 1 SIM (2) the data should be recorded.
Once you select a recipient, you'll see a list of all the contacts that you can select, you can mark specific entries manually, or you can click "Select All" at the top of the list. Be careful with "Select All" if you have a few thousand numbers in your memory, you'd better move them in packets over the top of the list. 100-200 So, when you confirm the selection, you start copying, and you can see how you're progressing on the screen.
| Parameter | Internal Memory / Google | SIM-map |
|---|---|---|
| Maximum number of contacts | No restrictions (depending on location) | About 200-500 pcs. |
| Photo preservation | Yes. | No. |
| Additional fields | All fields (email, address, etc.) | Name and number only |
| Network dependency | Required for synchronization | Not required (offline) |
When you do that, the system will give you a notification that you've copied successfully, and now your contacts are duplicated on the operator's chip, which means that even if you lose your phone or it completely fails, you'll insert it into the phone. SIM-card to any other device, you can restore communication with loved ones.
Working with contacts through Google Account
While direct export to SIM is convenient for quick migration, Xiaomi owners are strongly encouraged to use synchronization with Google Contacts as their primary method of backup.This approach is free of limitations on the volume and format of data. To set it up, go to Smartphone Settings, find the Accounts and Sync section, and select your Google account.
Make sure the slider opposite Contacts is activated, and once synced, all new records you create will automatically be saved to the cloud, if you still need to move your contacts from the Google cloud to the cloud. SIM-map (for example, to transfer to a button phone), this can be done through a web interface or application.
Xiaomi's Contacts app often has a group management feature, you can create a SIM group, add select numbers, and then export that particular group, a more flexible approach than mass exporting the entire book. Google Contacts (contacts.google.com) also allows you to export contacts in vCard format, but you still need a phone to write them to SIM.
β οΈ Attention: Google sync requires an internet connection.Make sure you have active Wi-Fi or mobile traffic before you start your operation to avoid data transmission errors.
Using a cloud account also makes it easy to restore contacts after resetting your settings to factory (Hard Reset). When you first log in to the dropped phone, the system will offer to restore data from the last backup, returning not only numbers, but also photos and addresses, which can never be done. SIM-map.
Addressing common problems
Users may encounter various errors during the copying process. One of the most common problems is the message that "Memory" SIM-This happens when the number of contacts selected exceeds the number of cells on the chip, and the solution is one: make room by deleting old records, or choose only the most important numbers to copy.
Another common situation is that contacts are copied but displayed as an "Unknown Number" or instead of a set of numbers, which often happens when you transfer from an iPhone or other systems where the formatting of the name may have been disrupted. SIM-map: you need to open a record, change the name (even just add a space at the end) and save again to overwrite the metadata.
What to do if the export button is inactive?
There are times when the phone just doesnβt see" SIM-This is a card in the context of the contact storage, although the calls are normal, and this may be due to damage to the chip's file system.
