@dancefighter69 conversations or blabber.im (a fork of conversations) for Android. Dino for desktop. If using windows, there's a fork/port of Dino for windows too.

You can probably find some asso like that in your country and donate to them until you can self-host.
For people who care about, support, or build Free, Libre, and Open Source Software (FLOSS).
