LINE usage environment
A phone number, email address, or Facebook account cannot be registered to more than one LINE account at the same time. When you register the same information to a new account, it is removed from the account it was previously used with.
A LINE account needs to be registered with a phone number or Facebook account at all times. If an account is no longer linked with either of these after information has been removed, it will become inaccessible.
Note: When an account becomes inaccessible, its friends, chats, and other data is deleted and cannot be recovered.
Take care not to use the same information registered to an account you're currently using if you make an account on another device. If you want to create multiple LINE accounts, you need to register them with different information and use them on separate devices.
Note: Only one LINE account is meant to be used per device.
All of LINE's basic features can be used for free.
Note: Some items, such as Coins and Stickers, must be purchased to use in LINE.
Please understand that you will need to pay for any data usage fees that you may be charged depending on the data plan you have with your mobile phone carrier. You may be charged every time you connect to the service if you are paying for only the amount of data you use. For this reason, we recommend signing up for a flat-rate data plan if you don't already have one.
All of LINE's features can be used for free, even when used from another country. If you use LINE with a friend living overseas, you will not be charged any fees for international use.
Please understand that you will need to pay for any data usage fees that you may be charged depending on the data plan you have with your mobile phone carrier, even if you are using the app overseas.
If you plan to use your device outside of the country you are contracted in, international data usage fees may differ. Please refer to your mobile contract, or contact your mobile carrier for further information about international data usage fees.
