Well, no.
No “ability” - since SK is, IIRC, one of the most “wired” countries in the world, and the US is still lacking in even adequate Internet service in a good many places (as Anymouse can, and frequently does, attest); and cellphone usage is FAR from universal, in any case.
I was wondering how far from universal so I did a little lookup. There are nearly 280 million cell phone subscriptions in the US. When you take out young children of which there are about 50 million, that is pretty ubiquitous. I know there are some folks who have a work and personal phone
Apparently 96% of US adults have either a smart phone or basic cell phone.
