How to save numbers from phone to phone SIM-Xiaomi

Switching to a new Xiaomi or Redmi smartphone often involves moving important information, and contacts are the first thing to keep. Device owners often wonder how to copy a phone book to a physical one. SIM-So you can use a map to keep your data from being lost when you change your gadget. MIUI HyperOS can hide some options, making the process unobvious to beginners.

It’s worth noting right away that the standard Android mechanism places limits on the number of characters in the contact name when saved to the SIM card, usually no more than 255 characters, and sometimes less. In addition, it’s impossible to copy additional data to the SIM card, such as avatars, email addresses or home addresses. Only the phone number and name will be transferred without distortion, so backing up to the cloud remains a more reliable method, but a physical medium is sometimes necessary.

In this article, we will take a detailed look at the algorithm for different firmware versions used in Xiaomi smartphones, learn how to avoid common errors and why some contacts may not show up after copying. Proper data preparation ensures that your phone book will remain intact under all circumstances.

Preparation of contacts for transfer and format limitations

Before you start the copying procedure, you need to understand the technical features of data storage on the computer. SIM-Unlike the internal memory of a phone or Google account, a SIM card has a very limited capacity and structure, usually containing 200 to 500 numbers, depending on the operator and year of release of plastic.

If you try to copy a contact whose name contains special characters or emojis, the system can automatically crop the name or replace the character with a space. This is the standard behavior of the GSM protocol, which is used to encode text on SIM cards, so it is recommended to pre-check the contact list and simplify complex names.

It is also important to consider that when you transfer from Google contacts to a SIM card, if one person has multiple numbers (mobile, work, home), several separate entries with the same name can be created on the SIM card, or only the main number will remain, which can lead to duplicate entries in the phone book.

• 📱 The maximum length of the contact name is limited by technical standard and is often cut to the length of the contact name. 10-15 symbolism.
• 🔢 A single SIM card can usually be written with no more. 250-500 numbers depending on the operator.
• ⚠️ Additional fields (address, notes, photos) are irrevocably deleted when copying to the SIM card.

⚠️ Warning: Before starting mass copying, make sure that your SIM card has enough free cells. If the memory is full, the process will interrupt, and some contacts may not last.

For users who store contacts exclusively in the Google or Mi Cloud cloud, migrating to a SIM card can be an intermediate step in migrating to a button phone or a device of another platform, in which case it is important to be aware of the loss of information.

Instructions: Copying through the standard Contacts app

The most common way to migrate data is to use the built-in Contacts app in the MIUI shell. The interface may vary slightly depending on the Android version, but the logic of action remains the same for most Xiaomi, Redmi and POCO models.

First, open the Contacts app on the home screen or in the Tools folder. In the upper right corner, you'll see a three-dot icon or a gear, which is the settings menu. Click on it to reveal the list of available operations.

In the menu that opens, find Import/Export contacts. This is where all the phone book management functions are concentrated. The system will suggest you choose the data source and the destination device. In this case, the source is the phone or the device, and the target is the phone or the device — SIM-map.

Once you select the source, the system will ask you to confirm the action, you can select all the contacts at once or check only the ones you want, and when you select all the contacts, it can take a few minutes, if they are large.

If you have two SIM cards installed on your phone, Android will ask which one (SIM 1 or SIM 2) you want to record your numbers. Be careful when choosing, as canceling the operation after recording starts will be difficult.

Alternative method through system settings

Sometimes the contact app is not working properly or the menu item is hidden, and in such cases you can use the system settings of the Xiaomi smartphone itself, which is a deeper method that allows you to manage contacts at the system level, bypassing the phone book interface.

Go to the main Settings menu and scroll down to the App section. Here, select System Apps to see the full list of embedded services. Find Contacts and click on it.

Inside the app menu, select Contact Recovery or Import/Export. Here, the functionality duplicates the capabilities of the main application, but sometimes works more stable when the interface crashes. SIM-map.

The system will warn you that some data may be lost due to storage format limitations, a standard Android warning that you can't ignore if you care about full contact profiles, and the copying process will begin once confirmed.

• 🛠 This method is useful if the standard contact application freezes or does not open.
• 📂 Allows you to manage contacts even when the call screen is blocked.
• 🔄 Ensures the use of system synchronization protocols without third-party interventions.

In some older versions of MIUI, this path might look like Additional Settings -> Contacts. If you don't find an item in the apps, try searching the global SIM settings search.

Working with several SIM-maps and source selection

Xiaomi smartphones often support two SIM cards at the same time, which creates additional confusion when copying contacts.

When you export contacts from your phone to your SIM card, the phone will suggest you select a target card. If you insert a new SIM card only into the second slot, make sure you choose SIM 2 in the export menu. Otherwise, you can try to write data to the already filled main card.

The reverse is importing from a SIM card to your phone. If you just inserted an old SIM card with numbers, go to the same Import/Export menu and select the source. SIM-The phone counts all available records and offers to save them in the memory of the device or in the Google account.

The format constraints remain throughout the information.

Problem Solving: Contacts are not copied or cropped

A common problem faced by Xiaomi owners is that the copying process is completed by an error or contacts are saved with cropped names, which can be due to overflowing memory of the SIM card or incompatibility of encoding.

If you have received a message that the memory SIM-The card is full, you have to delete some of the old entries directly from the SIM card or copy the contacts in small groups. Go to the contact menu, select the display only from the SIM card and delete unnecessary numbers.

The problem with encoding (where Russian letters are replaced by question marks or characters) is solved by changing the settings of the input language, but at the SIM card level this is difficult to do, in such cases it is better to use the intermediate stage: export to the.vcf file for internal memory, and then import this file through another phone or PC.

• 🚫 The “Insufficient Memory” Error Is Solved by Cleaning Up SIM arch-record.
• 🔤 Coding problems require manual renaming of contacts after transfer.
• ⏳ Copying process 500+ numbers may take up to 5-10 minutes, don't interrupt him.

⚠️ Warning: Do not remove the SIM card during the writing process, which can damage the file structure of the card and completely lose all the numbers recorded on it.

If none of the standard methods work, try using third-party apps from Google Play, such as "Copy My Contacts." These often have more flexible settings and can bypass some of the system limitations of MIUI.

Comparison of Storage Methods: SIM, Phone or Cloud

In the era of cloud technology, storing contacts on a physical SIM card is considered outdated, but still has its advantages. Let's compare three main ways so you can choose the best one for yourself.

SIM-The card provides maximum independence from the Internet and accounts. If your phone breaks, you just move the SIM card to any other device and the numbers will be with you.

The phone’s memory allows you to store full profiles with photos and sounds, but if you reset or break the device, the data will be lost forever unless you make a separate backup.

Google accounts are the gold standard, they provide full synchronization between your phone, tablet, and computer, and when you lose your phone, your numbers are restored instantly after you enter your login and password, and for Xiaomi owners, this is the most recommended option.

💡

Use a hybrid approach: store your main contacts in Google for sync, and SIM-Copy only the most important numbers in case of complete loss of access to the Internet or account.

If you change your phones often, the cloud is more convenient. If you use the same device for years or change SIM cards between different devices (for example, a navigator and a phone), a SIM card can be more practical.
