I'm so disappointed in this. Whatsapp is a functional tool. It was successful since it worked. Facebook has entirely failed to utilise it - to allow external systems to connect in so that businesses can do business on there. The voice calls are also a disaster. They've now come along to start messing with the privacy to start selling ads. It is insane that they're able to make such a mess of this. Is there a word for…
Whatsapp voice calls are pretty much the only way I can communicate with foreign family. Actually even locally, sometimes whatsapp calls are much better over wifi than cell calls over towers, it's kind of ridiculous. I don't even bother calling frequent contacts over cell any more.
With Whatsapp I would often get lag, echo and generally poor voice quality, with Signal it just works perfectly, even better than regular phone calls.
Give it a try and check if it's worth it for you.
