Making Calls With Iridium Satellite Phones

All calls made from an Iridium satellite phone are considered ‘International’ calls. If you’ve never made one before, it can be a bit confusing. This tutorial will help you make your first call and show you how to call an Iridium phone from anywhere.

Every Iridium phone is assigned a 9-digit international telephone number along with a 3-digit country code. The country code for all Iridium phones is 881. Iridium phone numbers can be called from any phone on the planet. If you don’t know your Iridium phone number, please contact your Iridium service provider or Ground Control. Or you can just call any phone with caller ID, which will show the Iridium number.

While the Iridium account will not be charged for any incoming calls placed to it, the calling party will pay for satellite Iridium phone rates. Charges vary widely between phone providers, from $1 to $10 U.S. per minute, and some phone providers block international calling. The calling party can ask their phone provider for their international plan rate to ‘Iridium’, which has its own country code of 881. Phone providers often have inexpensive international plans that can be added to avoid paying any exorbitant per-minute fees. Also consider adding a local number for the Iridium phone.
