Signal experience isn't that good. Alien from the platform they run on. For example, no system recommendations to send this person a message or share something with them through signal.. Telegram is more a platform native and integrated into the system.
Also there is the issue of messages arriving late (not minutes but hours late, sometimes days late)
Signal is honestly fantastic as a SMS-replacement app. It sends Signal messages to contacts with Signal and normal SMS to contacts without (Telegram might do the same thing, being able to set it as your default SMS app, I'm not sure).
In fact phone operators for a while tried to ban whatsapp here, SMS prices in Brazil are just nuts (it is normal for an SMS cost fifty cents or so, sometimes even more, a full SMS conversation can cost you several days worth of food).
Everyone here just uses whatsapp, because of how ridiculous SMS prices are.
That's what I love about these forums, is getting the cultural experiences of other people and finding out they're not always the same as your experiences. Very eye-opening.
