Making Calls With Iridium Satellite Phones

When using an Iridium satellite phone, all calls are classified as 'International' calls. If you're unfamiliar with this process, it can be somewhat confusing.  This guide aims to assist you in testing your sat phone and demonstrating how to make a call to an Iridium phone from any location to anywhere around the globe.

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 ISS representative. Or you can simply call any phone with caller ID, which will reveal the Iridium number.


To make a call from an Iridium phone into the United States, dial the United States country code (001), then the area code, and then the phone number.

For calling a US phone number from an Iridium Phone – example number: 001 805 783 4600
In this example, 805 is an area code in the U.S.

For calling into another country:

From outside the US, please use this tool to help you find the correct number sequence (detailed instructions follow below).

Example 2 – Calling an Iridium phone from Afghanistan: 00 881 672520732

Each country is different, but many countries do use 00 plus the country code. We also recommend using this tool to help you find the correct number sequence. If this doesn’t work, you can ask for assistance from an operator to help connect. You only need to know the 870 country code and the 9-digit Iridium phone number for the operator to connect you.

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.
