Tell users international text messaging is coming

Users might be interested in international SMS. And when it’s fully
available, they’ll probably be able to control whether it’s on/off for
their service.

Until they point, the only way of getting it is to ask us. So let’s
make an in-the-meantime page that directs them to ask us, from the place
where they’d be able to do it themselves.
