Telegram is like SMS, but more powerful. You can send messages, photos, videos and documents to people who are in your phone contacts (and have Telegram). You can also create groups for up to 200 people. Telegram is pretty similar to WhatsApp, but has some advantages.

Telegram is free: Protocols are open and clients are GPLv2. Communications are encrypted, and also end to end encryption is supported. You can use it on Android and iOS devices, but there are also unofficial clients for PC’s.
