Whatsapp is really a very good application. I don't know if this app is suitable for learning or not. I use WhatsApp to communicate with my friends and with my relatives who live very far away. This application allows you to transfer large files or send a message to a large number of people. These are much needed features and after the update Softgoza they are even better.
To be honest, I don't know much about messengers, but if I were to download a messenger, I would download Instagram. I think it's one of the most convenient and beautiful.
I found zoom to be the go to standard for conferences and it contains a messenger. But for group correspondence, text messages via SMS still seems the most universal. Nothing to install, and nobody is excluded.
