Started moving to Element/Matrix this weekend when I attended a protest and wanted to have some kind of communication, but also wanted to leave my primary phone at home. I was using a de-googled android fork and an e-sim, but being a data-only e-sim, I couldn't use Signal due to the phone number requirement.

Annoying to have try to get contacts to get another app, but at least it's decentralized and comes with the option of being self-hosted once I'm ready to tackle that.
