Not sure about Signal. I remember times when it was phone number focused. Having visible phone number in Russia means FSB might knock on your door.
The only thing better than telegram I can think of and relatively popular is Matrix. But even in my university I don’t know about anyone else, who uses it.
Is signal not a viable option? Or can you still not use it without leaking your phone-number?
