What messengers are you talking about? I only know a few messengers. One of them is viber. Previously, I used this application all the time, but recently something special has appeared. This is the Whatsapp app. This application is very good for those who make a lot of calls abroad and communicate a lot with relatives and friends. WhatsApp has a lot of useful features, and the best of them is the possibility of delayed sending messages. This became possible after installing the gbwhatsapp update
