Messenger provides a comprehensive set of communication features, including text messaging, voice and video calls, and group chats. Users can share photos, videos, and voice messages. The platform supports GIFs, stickers, and emojis to enhance expressiveness. It also offers real-time location sharing and integrates seamlessly with Facebook for social networking.

Messenger is free to download and use for messaging, calls, and media sharing. Data charges may apply when using it on a mobile network; using Wi-Fi is recommended to avoid extra costs. There are no hidden fees, although the app offers optional in-app purchases for certain features or upgrades.

Yes, Messenger can be used independently of Facebook. Users can register with their phone number and access the same features as those linked to Facebook. This allows individuals who prefer not to be on Facebook to still utilize Messenger's communication tools.

Messenger incorporates multiple security measures to safeguard user privacy and data. It features end-to-end encryption for secret conversations, ensuring only participants can read those messages. Users can activate two-factor authentication for enhanced security. However, standard chats are not end-to-end encrypted, so caution is advised when sharing sensitive information.

Messenger is compatible with most iOS and Android devices. It requires iOS 10.0 or later and Android 4.4 or higher. Keeping the app updated ensures access to all features and improvements. There is also a desktop version available for Windows and macOS users.
