I'm not sure about the US but in Canada it's certainly not true that everyone has data plans (in fact as far as I can tell unless you have a company sponsored phone, data plans are in the minority), and SMS remains a cheap communication method that is more or less guaranteed to work.

I live in Canada, and I don't know anyone who lives here that doesn't have a data plan of some kind, although I'm sure they definitely do exist and there are definitely people without a ton of data.

I'm not sure where you are but I find it quite uncommon for university students.

Really? I don't know many university students that don't have the latest smartphone(or at least a fairly recent one) which usually implies they have a data plan of some kind since most of them don't have $800+ to pay outright.

But to be fair at my university there are also a lot of students that drive brand new or fairly new cars too and I've parked beside too many Porsches the student parking lot.
