Allow whatever methods that allow the most people to contact them. Preferably a few. If WhatsApp + SMS get to 95% of the target population, I don't see why not. I'd personally prefer Signal for this sort of thing, but there's like 0.23% of people using it, so it seems kind of dumb to devote a lot of resources for Phil's Ideologically Blessed Methods.
