Real time mobile chat
Telegram is a cloud-based instant messaging service. Telegram clients exist for both mobile (Android, iOS, Windows Phone, Ubuntu Touch) and desktop systems (Windows, OS X, Linux). Users can send messages and exchange photos, videos, stickers and files of any type. Telegram also provides optional end-to-end-encrypted messaging, which has been criticized by security experts because of its custom nature. The service also has group chats that can be private or public.
