Yes, you can. The coverage areas of all of the satellite networks differ so it is worthwhile checking the appropriate coverage map:

Iridium Coverage Map

Inmarsat Coverage Map

Thuraya Coverage

Globalstar Coverage

If you are connected on the Inmarsat network, and using your service outside of US, the cost to call back to US will be the same as when you make a local call from within US. Incoming calls to your Inmarsat phone when traveling outside of the US are free on most handset plans.

If you are connected to the Iridium satellite network and are using your service outside of US your call rates will be different to those that apply when inside the US.

Before a phone call can be made, the phone needs a GPS fix so it can be located by the satellite. This happens automatically, but if a new GPS fix is needed the GPS fix icon will be displayed on the screen. The phone should be kept in the open with a clear view of the sky until the icon on the screen disappears. Once this is done the phone is now ready to register with the network.
