LINE: Free Calls & Messages — it is a service of sending free messages and calls which is very much on Skype or Viber. It will allow you to communicate using your phone with your friends and acquaintances without forcing you to spend a cent, if you have a stable Internet connection.
The messaging system will allow you to send not only text messages, but also images, videos, and even audio files that will come directly to the user with whom you are trying to communicate.
To make a phone call the user on the other end must also install the application on your computer. Once this is done, Line will inform you that your friend is also using the program and you will be able to call him for free.
