Chapter 1: Function

The core function of LINE: Calls & Messages is to facilitate real-time communication. It enables users to send text messages, images, videos, and voice notes to individuals or groups instantly. The app supports high-quality voice and video calls over Wi-Fi or mobile data, allowing for face-to-face conversations regardless of location. It integrates LINE's signature feature of a vast library of stickers and emojis to enrich expressive communication. Furthermore, the app provides essential management tools for contact lists and chat histories, ensuring that the basic framework for staying in touch is robust and accessible. All these functions are tied to the user's LINE account, synchronizing conversations across devices where the app is installed.

Chapter 2: Value

The primary value proposition of LINE: Calls & Messages lies in its dedication to providing a stable, high-quality, and free communication channel for a global user base. Its key advantage is the reliability of its call and message delivery system, which is built upon a robust technological infrastructure. Unlike the full-featured LINE app, this version focuses purely on communication, offering a potentially more streamlined and performance-optimized experience for users who prioritize calls and messaging over additional services like Timeline or LINE Games. The value is further enhanced by its cross-platform compatibility, allowing seamless interaction between iOS and Android users without cost barriers for standard calls and messages. It leverages LINE's established ecosystem, meaning users can communicate with an enormous existing network of friends, family, and colleagues. The app's emphasis on expressive communication through stickers and smooth video calls adds a layer of emotional value, making interactions feel more personal and engaging than traditional telephony. It represents a cost-effective solution for international communication, turning a smartphone into a powerful tool for maintaining relationships across borders.

Chapter 3: Scenarios

The primary target users are individuals with an existing social or professional network on LINE who seek a dedicated tool for core communication. It is immensely popular among friends and families separated by geography, such as international students keeping in touch with home or expatriates connecting with friends abroad. Small business teams or freelance collaborators who use LINE for quick project updates and virtual meetings also find it highly practical. Everyday use cases include making free video calls to grandparents, sharing daily moments via instant messages and photos in family group chats, coordinating event plans with friends through group messaging, and conducting brief check-in calls with remote team members. The app is particularly valuable in scenarios where traditional SMS or paid international calling plans are cost-prohibitive, providing a reliable and rich alternative that works over any data connection.

It also provides desktop applications for Windows and macOS, and a web version accessible through major browsers.

How does LINE protect my privacy and message security?

LINE employs end-to-end encryption for its one-on-one text messages, photos, videos, and voice messages through a feature called 'Letter Sealing,' which is enabled by default. For voice and video calls, encryption is also applied. User data protection policies are outlined in its privacy policy. The app requires permissions like contacts for friend discovery and storage for saving media.

What happens to my chats if I change my phone or number?

If you change your device but keep the same phone number, you can transfer your chat history using a move account feature or backup/restore function (availability varies by OS). However, if you change your registered phone number, you must change it in the app's settings first to retain your account and data. Failing to do so may result in losing access to your original account and chats.
