My favorite means of communication is telegram. I like telegram because it's confidential. All messages are securely encrypted with protocols and various encryptions.The most interesting thing about this messenger is that in conversations, no one will know anything about each other if you configure privacy in the settings.Also in this Messenger free music and stickers.At any time, you can share your mood with the other person with various stickers.
