Redmi 9: How to copy SIM contacts to Xiaomi phone

Switching to a new smartphone or recovering data after a system reset is often a stressful situation for the user, especially when it comes to keeping the phone book safe. Owners of Xiaomi devices, including the popular Redmi 9 model, face the need to quickly and reliably transfer numbers to avoid losing contact with close and business partners. Fortunately, the MIUI shell offers built-in and proven tools to solve this problem without installing third-party software.

There are several proven ways to import data, each with its own advantages depending on the amount of information and the status of the SIM card: you can use the standard contact menu, Google cloud services or the proprietary Mi Mover utility to migrate from another device. Understanding the nuances of each method will avoid duplication of records and loss of important details, such as additional numbers or email addresses associated with contacts.

In this guide, we will take a closer look at how you copy numbers directly from your SIM card chip to your Redmi 9 smartphone memory. We will look at step-by-step steps, possible errors when reading the card, and ways to optimize phone book storage for maximum security of your data in the future.

Preparation of SIM card and compatibility check

Before you start importing, you need to make sure that the physical storage medium is correct and correctly defined by the Android operating system.Put the SIM card into the corresponding slot of the Redmi 9 device and wait for the network signal to appear.If the card is new or previously used in the button phone, it may not have free memory or it may be formatted in an incompatible format, which will require prior verification.

Modern smartphones, including the Xiaomi Redmi 9, support reading contacts in GSM and USIM formats, but older cards can store data in a truncated form.This means that when you transfer, you can only see the main number, and fields such as name, title or second phone can be lost or cropped due to the capacity limitations of the SIM card chip.

To successfully perform the operation, make sure that the SIM card is not blocked. PIN-If you use the two-sim Redmi 9, the system will suggest you select a data source, so it is important to determine in advance which map to read the information from.

Import contacts through the standard application

The quickest and most direct way to transfer records is to use the built-in MIUI phonebook functionality, which requires no internet connection and works even in flight mode, making it a versatile solution for all conditions.

Open the Contacts app on the home screen or in the Tools folder. In the upper right corner or in the settings menu (three dots or gear), find Import Contacts. The system will suggest selecting a data source; in this case, we are interested in the SIM card option or «SIM-map 1/2».

Once you select a source, Redmi 9 will scan the SIM card memory, and if there are many records, the process can take a few seconds, and a list of contacts will appear on the screen, where you can deselect from numbers that you don't need to copy, such as service or test records of the operator.

The critical step is to choose a place to save, which will offer to save data in the memory of the phone or sync with the Google account, and it is recommended to choose a Google account, as this provides automatic backup and protection against data loss if the device breaks down or the loss of the SIM card.

⚠️ Note: When copying a large number of records (more than one) 200) process may take up to 1-2 Do not interrupt the process or switch between heavy applications to avoid a contact service failure.

Using Google Cloud Sync Sync

Google’s ecosystem provides a powerful contact management tool that Xiaomi users often ignore in favor of local storage. Using the cloud allows not only to transfer data from the SIM card, but also to instantly restore it to any new device after entering a login and password.

To get started, make sure your Google account is added to Redmi 9 settings. Go to Settings → Accounts and Sync → Google and make sure the slider opposite Contacts is activated. Then start importing from the SIM card through the contacts app as described in the previous section, but select your Google account as your target storage.

The advantage of this method is the ability to edit and clean duplicates through the web interface contacts.google.com. You can log on to the site from your computer, combine repetitive posts, add photos and missing email addresses, and all changes will automatically affect your Redmi 9 with the Internet.

💡

Check the “Current and Manage” section of Google’s contact settings regularly, and the system will find duplicates and suggest combining them, freeing up space and eliminating confusion in the phone book.

If you have previously used smartphones from other brands and have already saved numbers in Google, then when you log in to your account on Xiaomi, all contacts will be automatically pulled up, in which case you may not even need to copy from the SIM card, just check for all records in the cloud.

Data migration with Mi Mover

If you are switching to Redmi 9 from another smartphone (it does not matter whether Android or iOS, although Android is relevant for SIM cards), the best solution will be the Mi Mover utility. This application is pre-installed in the system and allows you to flip contacts, messages, photos and settings in a few clicks.

While the main Mi Mover scenario is Wi-Fi Direct, the app also works with local sources. However, if your target is a SIM card, then in the context of migrating from another phone, Mi Mover acts as an aggregator: it counts contacts from the memory of the old device (where they could have been copied from the SIM card before) and transfers them to Redmi 9 in full, preserving the structure and media attachments.

The process is this: run Mi Mover on both devices. On the new Redmi 9, select "I am the recipient"; on the old one, select "I am the sender." Scan. QR-In the list of transmitted data, be sure to tick the item "Contacts».

Using Mi Mover is especially important if the contacts on the old phone were stored in the device’s memory rather than on the SIM card, so copy them from the SIM card to the old phone first, and then transfer the entire dataset to the Redmi 9.

Solving and eliminating errors

While copying, Xiaomi users may encounter various system messages or incorrect display of data. One of the common problems is text encoding. If instead of letters you see question marks or characters, this means that the encoding of the SIM card (often GSM 7-bit) is not fully compatible with the current Android system encoding (usually UTF-8).

In this case, try to copy contacts in small groups (10-20 pieces each) If the error is repeated on specific records, it is likely that the contact name uses special characters or emojis that are not supported by the card chip.

⚠️ Note: If the system is writing "Memory" SIM-If the card is full or "I couldn't read the contacts," try removing the SIM card, erase the contacts with a pin and paste again. If the error persists, use a PC card reader or an old phone to upload the data.

Another common situation is the appearance of duplicates. After importing from a SIM card, the Redmi 9 phone book may contain two versions of the same number: one from a card, the other from the cloud. The MIUI system usually offers to combine them automatically, but if this does not happen, use the Contact Management → Combine Repetitives function.

Also worth remembering is the SIM card limits: Standard cards can hold 250 to 500 records. If you try to import more, the process can stop, in which case break the operation into stages or use intermediate storage in the memory of the phone.

Organization and security of the telephone book

After successfully migrating numbers to Redmi 9, it is important to properly organize their storage. Local storage in the phone’s memory (Phone Only) is convenient for speed, but dangerous if you lose your device. It is recommended to use a hybrid model: the main contacts are kept in Google, and service or temporary numbers can be left locally.

Backups regularly. Contacts has a function to export to.vcf. You can upload the entire phone book to internal memory or to the computer. SD-This file can be sent to your messengers or mail as an archive.

💡

The golden rule of security: Never keep a single copy of important contacts only on the Internet. SIM-Chips have the ability to suddenly fail, and their memory is limited and does not allow you to save complete contact profiles.

Use the sorting and grouping capabilities of MIUI. You can create groups (Family, Work, Friends) and assign unique ringtones to them, which is not only convenient, but also helps you visually structure a list of hundreds of numbers, making navigation quick and enjoyable.

Following these guidelines, you can quickly and without loss transfer your entire phone book to the new Redmi 9. Proper data organization from the very beginning of using the smartphone will save you a lot of problems in the future and ensure the safety of important connections.
