It doesn't seem to be on Elon Musk's radar (no pun intended) but if his or Amazon's reusable launch platform really does make commodity launches possible then it would make sense for Elon or someone to put up Iridium 2.0. Maybe Google or Facebook will do it to bring internet to the masses.
There is currently a company called Globalstar seeking permission from the FCC to offer satellite based internet services. The stock dropped 60% last week on rumors that they won't be approved but nothing has been confirmed.
SpaceX are working on a low orbit constellation to provide low latency satellite internet (for consumers). Presumably that could serve the purpose of an "Iridium 2"?
Oh I stand corrected then. In my opinion between a lower cost competitor to BGAN, extending higher speed internet to undeveloped and underdeveloped areas I believe there is a great deal of pent-up demand. That's before things like mandatory internet-connected aviation transponders as mooted elsewhere in this thread.
