My parents went to Costa Rica recently and were told in advance that basically the entire country used WhatsApp as their VoIP/messaging system. So I took it upon myself to get it going on their phones and mine as a result. And you know what? It's pretty good. It solved the Android vs iOS interoperability issues and I was able to tell my parents that no matter where they are, as long as they can connect to wifi, they can send messages. I'm not thrilled that it's a Meta product, but I'm inclined to believe them when they tell me it's end-to-end encrypted, so I've more or less adopted it as the neutral messaging app I'd recommend.
