Changing a smartphone is often accompanied by the fear of losing important information, and SMS correspondence is one of the most vulnerable areas. Messengers like Telegram or WhatsApp can synchronize history via the cloud, but standard text messages are tied to the local memory of the device. If you simply insert a SIM card into a new gadget, you will only see new messages, and all archived correspondence will remain in the old phone.
Fortunately, the ecosystem Android offers many tools for data migration, from built-in Google functions to specialized software. The transfer process may vary depending on the operating system version and your device model. In this article, we will analyze in detail all the current methods that will help you save your communication history without losing a single character.
Before you begin active actions, you need to make sure that both devices are charged at least 50-60%. Interruption of the data transfer process due to low battery may damage the backup files. Also check that you have a stable internet connection if you plan to use cloud services.
Using Google's built-in recovery when setting up for the first time
The easiest and most reliable way to transfer SMS is to use the built-in backup mechanism from Google. This feature is activated by default on most modern smartphones, but it is worth checking its status in advance. The system automatically creates backups of messages, call logs and application settings in your account.
To activate the function on your old device, go to Settings → System → Backup. Make sure the Backup Data switch is enabled and Messages is checked in the list of items to save. Here you can also click the “Start copying” button to create a fresh recovery point before purchasing a new phone.
When you turn on a new smartphone for the first time, log in to the same account Google. The system will offer to restore data from the latest backup. Select the required backup by date and confirm the action. The process may take from 10 minutes to an hour depending on the amount of data and network speed.
⚠️ Attention: Restoring via Google only works when setting up your phone for the first time. If you have already set up a new device and skipped this step, you will have to perform a hard reset (Factory Reset) to activate the recovery wizard.
It is important to understand that this method transfers messages in a “batch”. You will not be able to selectively restore only correspondence with a specific contact - the entire history will be returned at once. In addition, multimedia attachments (MMS) may not transfer correctly or take up significantly more space in the cloud storage.
Check the date of the last backup in the settings of your old phone. If it is a week old, new messages will not get to the new device until the next automatic backup.
Transfer via the SMS Backup & Restore application
If the built-in Google tools do not seem flexible enough to you or you want to transfer messages to an already configured phone without resetting, third-party software will be the best solution. The leader in this niche is a free application SMS Backup & Restore from the developer SyncTech. It allows you to create local copies and transfer them directly between devices.
Install the application from Google Play on both smartphones. Launch the app on your old device and click the “Create a backup” button. In the settings, select what exactly you want to save: only SMS, call logs, or all together. The application will create an XML file that can be saved in the phone's memory or directly sent to the cloud.
Next, you need to transfer this file to the new phone. The fastest way is to use the Transfer feature within the app itself, which creates a local Wi-Fi network between devices. Select “Send” on the old phone and “Accept” on the new one, then scan the QR code to connect.
- 📱 The method works without the Internet, using a direct Wi-Fi connection between phones.
- 💾 Ability to save a copy to Google Drive, Dropbox or local memory.
- 🔄 Support for scheduling automatic backups on a schedule.
- 📂 Ability to view the contents of the backup before restoring.
After completing the file transfer to the new device, start the restore process. The application will offer to replace current messages with data from the archive or merge them. It is usually recommended to choose a replacement to avoid duplication if you have already started using a new phone.
Using proprietary utilities of smartphone manufacturers
Large vendors, such as Samsung, Xiaomi, Huawei and others, are developing their own tools for data migration. These utilities often work faster and more stable than universal solutions, as they have deep access to the system. For example, Samsung owners use the application Smart Switch, and Xiaomi users use Mi Mover.
Let's look at the process using an example Samsung Smart Switch. Install the application on both devices (newer models have it pre-installed). Launch it, select the device role: “Sender” on the old phone and “Recipient” on the new one. Connect the phones with a USB-C to USB-C cable or via Wi-Fi Direct.
In the data selection menu, be sure to check the “Messages” box. You can also select specific dialogs if you don't want to transfer the entire amount of information. After confirmation, the transfer will begin, the progress of which is displayed on the screen in real time.
| Manufacturer | Name of the utility | Connection type | Features |
|---|---|---|---|
| Samsung | Smart Switch | Cable / Wi-Fi | Transfer home screen and alarm settings |
| Xiaomi / Redmi | Mi Mover | Wi-Fi Direct | High speed, works without the Internet |
| Huawei / Honor | Phone Clone | Wi-Fi Direct | Support for iOS and Android |
| OnePlus / OPPO | Clone Phone | Cable / Wi-Fi | Integration with OPPO Cloud |
The main advantage of proprietary utilities is the ability to transfer not only SMS, but also the desktop layout, Wi-Fi passwords and system settings. This allows you to make a new phone an almost complete copy of the old one, saving time on the initial setup.
Proprietary utilities often require that the same version of the application be installed on both devices for the transfer protocol to work correctly.
Manual export and import via Bluetooth
For users who do not trust cloud services or want transfer only a few important correspondences, there is a manual export method. The standard Messages application in pure Android (and in the shells of many manufacturers) allows you to save individual dialogs to a file.
Open the desired conversation in the messages application. Tap the three dots in the corner of the screen or hold your finger on a message to bring up the menu. Select "Advanced" or "More" and then look for the "Save to storage" or "Export" option. The message will be saved as a text file .txt or .vcf.
After saving the file, turn on Bluetooth on both devices and pair. Find the saved file in your old phone's file manager, tap Share and select Bluetooth. On the new device, accept the file and open it.
⚠️ Attention: This method is only suitable for archiving correspondence in readable form. You cannot import such a file back into the Messages application so that it becomes part of an active conversation using standard means. This is only a digital archive.
Some third-party launchers and SMS applications may support import from .xml or .json, but there is no universal standard for manual import via Bluetooth. Therefore, this method should be considered solely as a way to create a paper (digital) copy of important data, such as confirmation codes or legal notices.
Why is Bluetooth slow?
Bluetooth technology has low bandwidth compared to Wi-Fi Direct. Transferring 1000 messages can take up to 20-30 minutes, whereas via cable it will take a couple of seconds.
Problems with encoding and special characters during migration
One of the hidden problems when migrating data is different text encoding. Older phones may have used the GSM 7-bitstandard, while modern systems work with Unicode (UTF-8). When transferred through some converters, Russian letters may turn into “crazy words” or question marks.
To avoid text distortion, always select the saving format XML instead of CSV or TXT, if the application provides such a choice. The XML format contains metadata about the encoding, which allows the importing application to correctly interpret the characters. The CSV format often loses this information when transferred between different systems.
If you notice that messages are not displayed correctly after recovery, try changing the font in the settings of the new phone or updating the Messages app to the latest version through the store Play Market. Sometimes the problem lies not in the file, but in the font renderer of the new shell.
Particular attention should be paid to emoji. Emoji sent 5 years ago may appear as empty squares on a new phone if their code is not supported by the current version Android. This is normal system behavior, and it is technically impossible to restore their “native” appearance without emulating the old OS.
☑️ Checking data integrity
What to do if the transfer was not successful the first time
Technical failures occur even when using proven methods. If after recovery you see an empty list of messages or the process is stuck in the middle, do not panic. Often the problem can be resolved by simply clearing the Messages app cache on the new device before re-importing.
Go to Settings → Applications → Messages → Storage and click "Clear Cache". Do not confuse this with Data Wipe, which will delete everything that has already been transferred. After cleaning, try starting the recovery procedure again.
In cases where the built-in Google tools refuse to see the backup, check your account region. Sometimes backups created in one country are not visible when logging in from another region due to differences in server data storage policies. Try temporarily changing the region in your Google account settings.
⚠️ Attention: Settings interfaces and menu item names may differ depending on the version of Android and the manufacturer's shell (MIUI, OneUI, ColorOS). If you do not find the specified item, use the search in the phone settings.
If none of the software methods helped, the last option remains - using a computer. Connect your old phone to your PC, find the folder /data/data/com.android.providers.telephony/databases/ (Root access required) or use apps like Android Data Recovery to create a complete system image, which can then be deployed on a new device via ADB.
Before complex manipulations with root access, be sure to make a full backup of the system via TWRP or a similar recovery in order to be able to roll back changes in case of an error.
Is it possible to transfer SMS without Internet?
Yes, it is possible. Use applications such as SMS Backup & Restore with transmission over a local Wi-Fi network or proprietary utilities (Smart Switch, Mi Mover) working via Wi-Fi Direct. Connecting with a cable between phones or via a computer is also suitable.
Will deleted messages be saved during transfer?
No, only those messages that are physically in the phone’s memory at the time the backup is created are included in the backup copy. It is impossible to recover deleted messages through standard transfer tools, only through specialized data recovery software with deep memory scanning.
Will SMS take up a lot of space in Google Drive?
Text messages take up negligible space. Even 10,000 messages weigh only a few megabytes. The main place in Google's quota (15 GB) is occupied by photos, videos and files from mail, and not SMS archives.
Do I need to insert an old SIM card into a new phone?
To transfer correspondence history, a SIM card is not needed, since SMS are stored in the device’s memory, and not on the card. A SIM card is only needed to receive new messages and confirm the number when logging into accounts.
