Granted I did a little bit of work to convince them, but "you can use it on your computer and do video calls with your phone number" was good enough, even if vaguely inaccurate. It's much more functional than SMS.
But that's also in the US, I think other apps are more popular plenty of places which are just as much better than SMS anyway. Signal I think has good adoption in the US because the competitor was so terrible.
> The most common apps chosen as alternatives were Telegram and Signal, mostly because of their privacy and security features. However, almost a third of the participants that tried to switch chose to move to either Facebook Messenger or Instagram.
> 25.97% of participants wanted to switch to other apps but only 0.5% uninstalled WhatsApp ... If we translated this result to the entire population of WhatsApp users (approx. 2 billion), we’d be talking about 500 million users trying to flee from WhatsApp, and only 10k uninstalling it.
In this researcher's own words: "It looks like WhatsApp is the place to chat with anybody, making it particularly hard to leave."

For instance I switched to signal and use it regularly, but keep whatsapp on my phone for a few contacts I might need a few times per year. Whether it is uninstalled seems like the wrong metric and does not say anything about signal usage.
