About main and sub devices
Main device
Your main device (primarily a smartphone) is the device you used to create your LINE
account.
On your main device, you can manage your LINE account
information, such as your phone number, email address, and password.
If you want to change
your main device (e.g. due to getting a new smartphone), you need to transfer your LINE account.
Be advised
- If you register a new account using the phone number, Apple ID, or Google account that is already verified on another main device, your previous LINE account will be automatically deleted.
- Deleted LINE accounts cannot be restored.
Sub device
Using the same LINE account on another device as you do on your main device makes that device a sub
device.
You can use the same LINE account on a sub device by logging in with the account information
you registered on your main device.
