Transfer phone data without a PC

This year, the Apple event for the iPhone 15 will happen on 12 September 2023. The smartphones will then hit the market from 22 September.

After the excitement of the new iPhone devices, users have to deal with the challenge of transferring data to the new iPhone. For technical users, this may not be a problem. But for regular people, it is. Especially transferring data from specific applications like LINE.

LINE is one of the largest social messaging apps in the world with 84 million active monthly users. After getting a new phone like the iPhone 15, LINE users would want a secure way to transfer their data from their LINE app without losing it.

Thankfully, there are several official ways to do it through the LINE app platform but the two most popular ways are through the QR code and using your phone number.

Users transferring LINE by QR code require 3 things;

  • Active LINE account and access to both devices.
  • An updated LINE version 12.10.0 or later
  • A stable network connection.

Here are the steps to transfer your LINE using an easy transfer QR code:

1. Download and open the LINE app on your new device. Then tap Login.

 open line on your mobile

2. Next, Tap Log in with QR code > Scan QR code.

Note: If the app requests that you allow video or photo access, then please do so to proceed.

4. Use your new device to scan the QR code on your old device to verify your identity.

5. After that, a pop-up will appear "Did you just scan this QR code?". Simple check Yes, I scanned the QR code myself and tap Continue.

Note: If you had a passcode or unlock method set on your old device, you may need to verify your identity on it.

6. Still on your new device, log in as [your profile name] screen.

7. If you are transferring to the same OS and you had previously backed up your chat history, you can choose whether to restore your chat history or not.

Note: If your new device is not running the same OS as the old one, tap Skip for now.

8. Ensure you're logged in to the LINE app on your new device and wait for a while. Your data will sync, and once the process is complete, you will be logged out of LINE on your old device.

With these 8 steps, you are ready to use your LINE app in your new iPhone 15. But the QR code method requires you to have both your old and new devices. So, what if you sold your old device or traded in for the new iPhone 15? In cases where you have only your new device, you can transfer your LINE data using your mobile number.

Transferring LINE by phone number

This method is also popular since everyone using LINE already has a phone number. It restores LINE data that is linked to your mobile number. The LINE app will recognize your number on the new iPhone 15 and it will prompt you to restore your chat history.

To use this option, you must have registered your LINE account with a phone number and password.

Follow the below steps to transfer your LINE data using your phone number:

1. Open the LINE app on your new iPhone 15 and tap Log in.

2. Then tap Login with phone number.

3. Next, select your country and enter your mobile number. Then tap ‘>’ to Send.

4. You receive a verification code via SMS, enter the verification code.

5. To confirm your account, tap Yes, that's my account.

6. Then enter your password and tap the arrow to proceed.

7. On the next page, Tap Yes, restore my chats > Continue.

Note: Clicking on Continue will disable the LINE account on your old device.

8. Next click on Restore chat history.

9. Then enter your backup PIN.

Note:If you had set a backup PIN on your old device, the backup PIN entry screen will appear on the new one.

10. Next, choose whether you want to add friends from your contacts, then tap the arrow.

11. Finally, the "Regarding Usage of Your Information" screen will pop up, confirm it.

Note: In some cases, it may not appear.

The official methods from LINE works well because you can use the QR code option directly from the LINE app, and for the second option, everyone has a phone number. But there are some cases where another option may be more suitable for you.

Method 2: Transfer LINE to New iPhone 15 with MobileTrans

Transferring LINE via the official QR code takes 8 steps. By phone number, it takes 10 steps. With MobileTrans, you only need about 4 steps to transfer your LINE data. So, using MobileTrans is faster and less technical.
