How to clean the SIM card on the phone xiomy

Modern Xiaomi smartphones that work on the shell MIUI HyperOS, or HyperOS, has a huge internal memory that allows you to store thousands of contacts without restrictions, but if you switched from a button phone or used an old method of saving for a long time, your numbers can be directly on the phone. SIM-Not only does this limit the number of characters in the contact name, it also prevents full synchronization with your Google account.

Many users face a situation where, after installing a new SIM card in the device, the phone offers to copy contacts, but does not explain how to remove the originals from the chip. Cleaning the SIM card storage is an important step in optimization, which eliminates duplicates and speeds up the phone book. In this guide, we will examine all the nuances of working with contacts on devices of the Chinese brand.

The process of deleting data does not require root rights or third-party software installation. All the necessary tools are built into the standard application "Contacts", which is a system component of the MIUI shell. Proper management of the database of numbers ensures that when you change your device, you do not lose important connections and can easily restore them from the cloud.

Why it is important to transfer contacts to your phone memory

Storing numbers directly on a carrier chip is considered an outdated approach that was relevant in the days of phones with minimal internal memory, a major drawback of this method is the rigid limit on the length of the contact name, which is often cut to the limit of the length of the contact name. 10-15 symbols, and the inability to add an email, address or photo, SIM-The card has a limited amount of memory for records, usually not exceeding 250 contact.

When using Xiaomi smartphones and the Google ecosystem, the best solution is to store data in the cloud or internal memory of the device, which provides instant synchronization between the tablet, phone and computer. If you lose or break your phone, contacts will not be lost, since they are tied to your account, not to a physical plastic chip.

⚠️ Note: Before any manipulation of the database is initiated, it is strongly recommended to create a backup copy, which will allow you to recover information in the event of a failure or mistaken deletion of the desired numbers.

Another important aspect is speed, because with a lot of SIM card entries, it can take longer to load the phone book when the device is turned on, and it can take longer to find contacts, and moving the records to internal memory takes that load off the communications controller and speeds up the interface response.

Preparation for cleaning and backup

Before you start deleting data from your SIM card, you need to make sure that all important numbers are stored elsewhere. Xiaomi smartphones use the “Contacts” app by default, which allows you to flexibly manage storage sources. First, check where the new numbers are stored to avoid confusion in the future.

To create a reliable copy, use the import and export function. This action will create a.vcf file that can be saved to internal memory or sent to yourself by email. This file is universal and opens on any device, including iPhone and Android from other manufacturers.

If you're using a Mi Account or Google account, make sure that sync is enabled. Go to your system settings, find Accounts and Sync and check your status. If the slider is active, your contacts are already safe in the cloud, and clean up the physical media painlessly.

Save the backup file to your computer or cloud storage (such as Mi Drive or Google Drive) so you can access it even in the event of a total loss of your phone.

Removal of duplicates and consolidation of records

Often, after transferring data, users face the problem of duplication, the same number can be displayed twice: once as a write on a SIM card, the second as a write in the memory of the phone. The MIUI shell offers an automatic tool to solve this problem, which greatly simplifies life.

In Contacts, click on the menu (three dots) and select Clear Duplicates. The system will analyze the database and suggest combining the repeated entries, which does not delete information, but merges two contacts into one, storing all the associated data: photos, addresses, additional numbers.

• 🔍 Select "Clear duplicates" in the tool list.
• ✅ Confirm the combination of the proposed pairs of contacts.

⚠️ Warning: Don't choose the option"SIM-map as default save location, which will result in the loss of additional fields (email, address) and the length of the contact name.

Changing this setting also affects call behavior, so when you get a call from an unfamiliar number and you want to save it, the phone will immediately suggest the account you've chosen, saving you time and eliminating unnecessary clicks every time you save it.

For enterprise users or those who use multiple SIM cards, it is helpful to know that settings can be applied globally. However, in some dual-SIM use cases, the system may ask for a save location each time unless a strict priority is given.
