Surviving without a smartphone I do believe will be possible in Israel at least for many years. There’s enough of a population here that is not willing to touch one with a ten foot pole that forces the government and institutions to make sure they can access things without a smartphone.
Even so as crazy at it sounds, there’s lots of other groups and people living in the USA that don’t own smartphones and who aren’t Jewish. Everyone has their own reasons, but their are lots of non-jews who dislike the affects of smartphone use too. When I was trying to get rid of mine finding other people who weren’t Jewish and had no push from anyone or any community or religion nor knew anyone living without a smartphone besides for themselves really gave me chizuk.
