$12 activation and $10 per month plus calls (contact OCENS for rates for your satellite system).
VOCO local calling allows you to set up a local number for someone to use to get in touch with your satellite phone. Rather than having the caller make a International call (which can be very expensive) to your satellite phone, they would be making a local call. It is also much simpler than making a two stage call each time.
Incoming calls to your Iridium phone via your VOCO number are billed to you at only $1.75 per minute. Calls to your Inmarsat phone via your VOCO number are billed to you at just $3.99 per minute.
VOCO can be added to any new or existing satellite account.
