Line App Walkthrough: Message Friends & Family Anytime

Mobile Apps

With all the available messaging apps for both iOS and Android, choosing the one for you is tricky. But, among those getting a lot of attention is the LINE app from Japan. 

Let’s have a quick rundown of the Line App.

What Is LINE?

Line is a free messaging app offering unique features like stickers, games, video calling, and a bunch of other individual apps connected to the services. Although it is from Japan, it is owned by Naver, a Korean company. They chose Japan as the primary market because of the tight competition with Kakao.

Line has over 218 million monthly active users scattered in Asian countries such as Thailand, Indonesia, and Taiwan. It has more than 35 apps available to download, including the leading messaging app. Apps include music streaming, on-demand car service, cartoon app, and payment services.

The user base of Line is not as huge as other iOS and Android messaging apps like Facebook Messenger and Whatsapp, but it pioneered on messenger trends specifically in monetization. 

Let’s deep dive into how the LINE app works and discover why it is one of the most essential mobile apps you must download.


How to Register with LINE?

Like Whatsapp and Viber, Line also requires you to register using your mobile number. You need to verify your registration using a code from the SMS sent to your mobile phone. 

  1. Go to the App Store or Google Play to download and install the LINE app.
  2. Launch the app/ 
  3. Enter your mobile number.
  4. Enter the verification code.
  5. Add your friends or skip it.
  6. Start using the app.

For step #6, Line asks to access your contacts to add friends that have the app installed automatically; you can disallow access if you want. 

If you register first via your computer, then the app will ask for your email address. Line will send an email with a code to verify the email address you added. To download: 

  1. Go to
  2. Click Download from the menu.
  3. Choose PC/Mac (the website automatically detects your OS).
  4. Enter your email address.
  5. Wait for the verification code in your email. 
  6. Use the code to verify your email.

You can relaunch the app should there be an error message during the verification process. Other times, the app prompts you with an error message especially when you stay on the verification screen for too long.

If the verification screen didn’t prompt, then it means that your account is verified.


Another Verification Process

Call Me Instead 

Line gives you another way to verify your phone number in case you did not receive the verification code of your phone number. By tapping Call Me Instead, Line will automatically call you and provide your one-time verification code to complete your sign-up process. You should enter that code into the LINE app to get your account verified.

Line is also available on Chrome as a browser extension. Both registrations will ask you to add a display name if you want others to add you through your username or disable it so they won’t be able to find your account. The display name is limited to 20 characters only. 

In addition to their free user-to-user messages and calls, like Skype, Line offers paid calls to mobile devices and landline users. It also added a feature to call users that are not Line users, plus domestic and international calls for free.
