    Telegram review by Hanna L.
    "Telegram is an application that we should all know. : Every day communication offers us different ways to reach it, what was previously limited to radio, press and television today comes to us from a large number of different ways. One of the most used at the moment is instantaneously by means of applications of the different means, applications of the different social networks like for example Twitter or the applications of instantaneous mail, as it is the case of Telegram, besides offering instantaneous mail it offers us, between others, content hosting, files, content search, calls, supergroups (with a capacity of up to 100,000 users), is available for almost all existing platforms, both for smartphones and tablets and computers, we can have secret chats, this option has an exclusive encryption for the sender and the receiver, having to be previously accepted by the receiver, which guarantees that what is sent or written in that chat can only be read by the members of the chat. Telegram is not only the most secure instant messaging application, it also allows you to share files, a nice interface and it's free, I use it to communicate and share information with clients and colleagues.
