Anyone wishing to call an Iridium phone from a landline should use the Two-Stage Dialing platform, which will save you from paying the very high long-distance rates often charged for calls to satellite systems. Dial +1-480-768-2500 and enter their Iridium phone number (a 12-digit number beginning with 8816XXXXXXXX). Note: The Iridium subscriber will also incur an incoming charge for this call.

It doesn't matter where the satellite phone is located; the dialing pattern is the same. From the landline, dial: (your country's International Direct Dial access code) + 8816 + XXX XXXXX (phone number).

From the satellite phone, dial: 00 + 8816 + XXX XXXXX (phone number).

No, Caller ID is not optional. Like mobile and terrestrial networks, Caller ID is a feature that users expect and we’ve enabled it for them at no additional charge. 

The ability to dial a toll free number is determined by provider of the toll free number.
