About main and sub devices:
Main device
Your main device (typically your 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. To change your main device and use the same LINE account when you change devices, you need to transfer your LINE account.
warning icon  Be advised
If you register a new account using a phone number, Apple ID, or Google Account that is already verified on another main device, your previous LINE account will be automatically deleted. Please understand that we cannot restore an account after it is deleted.

Sub device
When you use the same LINE account as your main device on other devices (typically PCs or tablets), those devices are referred to as sub devices. By logging into a sub device with the LINE account information you registered on your main device, you'll be able to use the same account on both devices.
