[2025 Full Guide] How to Transfer LINE to a New Phone

Upgrading to a new smartphone is exciting, but the thought of losing your precious chat history and LINE data can be daunting. LINE, like any messaging app, requires a specific process to ensure a smooth transition of your account, friends, stickers, and especially your conversations to your new device. Don't worry, it's easier than you might think, as long as you know the right steps.

This comprehensive guide will walk you through everything you need to know about how to transfer LINE to a new phone, covering both iOS and Android devices, and addressing the critical differences when moving between operating systems.

Part 1. Before You Begin: Essential Preparations for a Smooth LINE Transfer

A successful LINE transfer starts with a little preparation on your old phone. Taking these crucial steps will help prevent data loss and ensure a hassle-free migration.

• Update LINE and Your Phone's OS

Before doing anything else, make sure both your old and new phones have the latest version of the LINE app installed. Also, ensure their operating systems (iOS or Android) are up-to-date. This helps prevent compatibility issues during the transfer process.

• Link Your LINE Account

For a seamless transfer, your LINE account needs to be linked to easily verifiable credentials. To do this, you often need to connect it to your phone number, email address, and, if you like, your Google Account or Apple ID. On your old phone, go to Settings > Account in LINE and confirm your phone number and email address are registered and up-to-date. Set a password if you haven't already.

• Ensure Stable Internet Connection and Sufficient Battery

Both your old and new devices should be connected to a stable Wi-Fi network and have sufficient battery life (preferably charged to 80% or higher). Data transfer can consume battery and requires a consistent connection.

• Back Up Your LINE Chat History

This is perhaps the most critical step, especially if you want to keep chat history older than 14 days. LINE's chat backup primarily relies on your phone's cloud service (iCloud for iOS, Google Drive for Android).

How to Back Up on iOS (iCloud Drive)

Step 1. On your old iPhone, open LINE and go to Home > Settings (gear icon) > Chats.
Step 2. Tap on Chat history backup > Back up now.
Step 3. Ensure iCloud Drive is enabled for LINE in your iPhone's system settings.

How to Back Up on Android (Google Drive)

Step 1. On your old Android phone, open LINE and go to Home > Settings (gear icon) > Chats.
Step 2. Tap on Backup and restore chat history > Back up to Google Drive.
Step 3. Select the Google Account you wish to use for the backup.

Part 2. How to Transfer LINE to a New Phone via QR Code [Android & iOS]

This is LINE's most straightforward and recommended method for transferring your account and the last 14 days of chat history to a new phone. It works seamlessly even when moving between iOS and Android.

Step 1. Open LINE on your old phone. Ensure your old phone is still active and connected to the internet.
Step 2. On your old phone, open LINE, go to Home > Settings (gear icon) > Easy transfer. Tap on "Generate QR code". A QR code will appear on your screen. Keep this screen open.
Step 3. Install and launch the LINE app on your new phone. Tap "Log in", then select "Log in with QR code". Allow camera access if prompted, then use your new phone to scan the QR code displayed on your old phone.
Step 4. Follow the on-screen prompts. You might be asked to verify your identity by entering your LINE password or a verification code sent to your registered phone number. Your account and the last 14 days of conversation history will sync with your new phone after verification. Your old device will automatically be logged out.

Part 3. How to Transfer LINE to a New Phone via Backup [iOS-to-iOS or Android-to-Android]

If you're moving from one iPhone to another iPhone, or one Android to another Android, and you want to restore all your chat history (older than 14 days), this is the method for you. It relies on your cloud backup.

Step 1. Perform a full chat history backup to iCloud (for iOS) or Google Drive (for Android) on your old phone, just like the tutorial shown in Part 1.
Step 2. Download the LINE app from the App Store (iOS) or Google Play Store (Android) and launch it.
Step 3. On your new phone, tap "Log in". Do not use the QR code option if you intend to restore your full chat history from cloud backup. Instead, choose to log in using your:
▪ Phone Number: Enter your registered phone number and password. You'll likely receive a verification code.
▪ Email: Enter your registered email and password.
▪ Apple ID / Google Account: If previously linked, select this option.

Step 4. After successfully logging in, LINE will detect your cloud backup and ask if you want to restore your chat history. Tap "Back up and restore chat history" or similar to begin the process. Ensure you're connected to Wi-Fi.
Step 5. Once the restoration is complete, follow any remaining prompts to finalize your LINE setup. Verify that your chat history, friend list, stickers, and other data have successfully transferred.

Part 4. How to Transfer LINE to a New Phone without Backup [iOS Only]

While official LINE methods are limited for cross-OS chat history, and the 14-day rule applies to the QR method, if you are looking to transfer all your LINE chat history specifically between iOS devices, or to back up your iOS LINE data to a computer, third-party software can offer more robust solutions.

TunesKit WhatsApp Transfer is an example of a desktop application that has expanded its capabilities to support LINE data for iOS users. It allows you to move your entire LINE chat history directly from one iPhone/iPad to another iPhone/iPad.

How to use TunesKit WhatsApp Transfer to transfer LINE to a new iPhone

After TunesKit WhatsApp Transfer installation, connect your two iPhones to your computer via USB cables. Within the TunesKit software interface, you would typically select the LINE option.

Step 2Transfer LINE data to your new iPhone

Select the Transfer feature and check if your destination device and source device are correct. After that, click the Transfer button to start moving your LINE chat history from your old iPhone to the new one.

Part 5. Conclusion

Transferring LINE to a new phone doesn't have to be a headache by following these steps and understanding the nuances of chat history migration. For cross-OS transfer, the QR code login method would be your best choice. If you have LINE backup in advance, you can transfer LINE data with the help of iCloud or Google Drive. If you don't have a backup, you can use TunesKit WhatsApp Transfer to move LINE chat history in one click.
