You can download Signal APK directly from their website.

In some different countries, WhatsApp is how people conduct business. I am anti WhatsApp in my regular life, but I used it with a VOIP number when I was traveling abroad.

I miss flip phones for similar reasons. I loved flicking them open and snapping them shut.
