SMS is not an option because, again outside of the US, people pay by SMS sent.
There are plans for Whatsapp interop but probably only in the EU.

Countries like Mexico or Spain have adopted it as the default form of messaging. Only today I used it to chat with our lawn maintenance guy, our car washer, and someone who's repairing our espresso machine.
I could maybe try to convince friends and family to use another app but I won't be convincing an entire country.
I just don't think anyone can be using Facebook/IG, especially persistent mobile apps, while have any real concern about tracking.
Does FB still run their Tor onion service? That seemed to be the only possible way to use these products in the past without being subject to extreme tracking.
Which is why there is a role for gov in regulating privacy and mandating interop between platforms. Asking people to “just stop using them” isn’t a realistic ask.
Facebook solves this problem extremely well. I still remember the “good old days” of poorly managed Wordpress sites, shared Google calendars, mailing lists, and texts, and I’m not particularly keen on going back to that.
The sad truth is that there is nothing on the market today that solves this problem in a combined package, and you can add discoverability to the mix. If you’re interested in X you can search for it on Facebook and 9/10 times you’ll find what you’re looking for, from menus for restaurants to opening hours. Yes, Google does this as well but somehow people (here) are more aware of the feature on Facebook.
Now a lot of that stuff is on WhatsApp.
I dumped Meta probably a decade ago, and anyone who wants to get in touch with me does so through e-mail.
But I still have two relatives stuck on FB Messenger. Even if I contact them via SMS, they still respond to my dormant account in FB Messenger, because Messenger is where all of their friends are. To them, it's the only messaging app, and have no idea why it doesn't work sending messages to me.
Imagine living without a phone, or whatever is equally important in your area. Sure, it is possible, if you're at the right level of masochism.
