Telegram is a cloud-based mobile and desktop messaging app with a focus on security and speed.
Telegram is in my opinion the best messaging service in the world, crazy features developed by highly skilled developers and awesome apps for mobile, desktop, web, and more.
Telegram allows you to have huge groups where to put your fans for instance, with no limits, premium features, and free features.
Telegram is amazing, fast, and secure, the only thing is that is not as private as Session but still way more private than Whatsapp.
Telegram allows you to make calls and video calls and you can use it to call your fans or family members.
