What countries can I use LINE Stickers Premium in?
LINE Stickers Premium can only be used with LINE accounts that have been registered with an Indonesian, Japanese, Taiwanese or Thai phone number.
Also, if you change your phone number (e.g. because you moved), you can continue using LINE Stickers Premium as long as your new number is for Indonesia, Japan, Taiwan, or Thailand.
Note: You may no longer be able to use stickers, emoji, and themes that can only be purchased/downloaded in certain regions after changing your phone number. For details, see the following Help article.
