Can I send a fax using Iridium?

Yes, by connecting the uniHub (an Iridium specialized product offered by On-Go) to your Iridium phone and fax machine it is possible to send and receive faxes over the Iridium network. The Iridium end user can choose to subscribe to the On-Go fax service which will allow the Iridium end user to send faxes to and receive faxes from any fax machine; in this configuration, only the Iridium end user needs to have a uniHub. Or if both parties have Iridium phones, then both parties can simply install the uniHub; in this configuration, it is not necessary to subscribe to the On-Go fax service, but each party needs to have a uniHub and an Iridium phone.
