You can send messages, photos, videos and files of any type with a focus on speed and security with Telegram Messenger.
Telegram feels in many ways like a straight-up clone from its green double-checkmark read receipts to its cartoonish wallpapers.
There’s also the usual gamut of messaging app features including the ability to see a friend's online status and attach photos, videos, your location, contacts, and documents to messages.
But where it lacks originality, Telegram Messenger makes up for it in speed and security features.
Telegram is the fastest and most secure mass market messaging system in the world," the company claims, which it attributes in part to Nikolai Durov’s open-sourced MTProto protocol. Telegram was in fact built as a testing bed for MTProto, Reuters reported when the app launched back in August.
In the process of testing out this functionality of the App, I called a friend of mine in the UK with whom I had not spoken to for the past three years. He didn’t have the Messenger app installed, but we were able to talk for several minutes without any problem.
This is an unofficial application and it is not endorsed by the creators of Telegram or Telegram Messenger customer service.
