Telegram is a free Instant Messaging application that boasts simplicity, speed and security. Telegram supports iOS, Android and Windows Phone. It also extends support for computers with its desktop applications for macOS, Windows and Linux. Telegram has some of the most well-connected data centres worldwide allowing for speedy messaging, high reliability and high performance. You can create groups of up to 200,000 people, share extremely large files and even create bots to perform certain tasks. Telegram is extremely secure and employs state of the art encryption methods to protect your information. Telegram also has a “Secret Chats” feature where messages can be programmed to self-destruct automatically from both devices after a set period of time. Telegram was one of the first instant messaging applications to bring file sharing into mainstream messaging applications. It even had GIF and stickers long before Whatsapp or Facebook Messenger adopted it.
