Do you want to add or remove a friend form your friends list in Line?
There are many ways by which you can add a new friend.
Open the application on your gadget and click on the specified symbol shown below.
The easiest way is to have the operator number of your friends saved on your gadget's contact list, so that you will be notified as soon as your friends join any networks. If the person you want to add has not signed up for Line yet, you can send an invitation to him/her via text message or email.
Of course, if your friend is sitting near you, you can both shake your phones at the same time to be added to each other's friend list.
Or ask for the person's Line user ID and add her/him directly.
