The cheapest plan on that page is $30. I get unlimited MMS on my $17 plan in Europe, so I don't see how the pricing would make MMS more prevalent in the US than in Europe.
Do you have a reference supporting the idea that MMS is mostly relevant to the US and not the rest of the world? It doesn't match up with my experience, but maybe my family and friends are atypical.
