Telegram

Telegram is a messaging app created by former VK creators with a focus on speed and security. It’s superfast, simple and free. It is like SMS, but more powerful. You can send messages, photos and videos to people who are in your phone contacts (and have Telegram). You can also create groups for up to 20000 people or channels for unlimited subscribers. Your chats are not encrypted by default, which enables other people to see what you are writing.
