In my country (Mexico) it'll be pretty much impossible, everyone uses WA/Messenger (both FB owned) many businesses/stores have support via those channels (and that support is almost always faster than calling them)
Also my appartament building has a WA group where people notifies important stuff.
And to add insult to perjury most data plans include WA/Messenger/FB free.
I tried years ago (2014-15) to stay telegram only and eventually I had to give up.
