LEO activity picks up, that may change, because maintaining good contact
with LEO spacecraft using ground stations is difficult -- the coverage
line-of-sight region of a single station is too small. However, there's
no need to launch your own satellites: people like Inmarsat will happily
sell you communications services. Back when Spacehab was proposing a
commercial ISS module, for example, it was going to have its own Inmarsat
antenna.

In theory, a Globalstar or Iridium phone could provide a low bandwidth
connection anywhere in LEO at a pretty nominal cost. I suspect that
their tracking, routing and Doppler shift software would get pretty
confused by a phone going 18,000 mph,
