    How can I configure SOS settings on an Iridium GO!?
    You must configure the SOS button in order for the SOS to send an emergency message to a designated Call Recipient and Message Recipient. Failure to configure the SOS button may result in no message being sent when the SOS button is pressed. This could prevent or delay an emergency response and result in serious injury or death. Using the Settings menu in the Iridium GO! application, you may configure SOS while paired to the Iridium GO! device. Only one SOS emergency contact setting can be stored per Iridium GO! device, so multiple users will all share the same SOS settings. It is important to plan accordingly. The SOS settings will provide the option to use or not use the GEOS service. To support the SOS feature, Iridium has contracted with GEOS Travel Safety Group to provide an emergency response coordination service for your Iridium GO! at no additional charge. Standard airtime charges will apply to SOS mode messages and/or calls to GEOS; a valid Iridium SIM subscription and online registration at is required.

This is a free service for Pulsar Iridium customers.
    How do I make a satellite phone call?
    Pulsar satellite phones generally include a truly local number that works just like your cell phone to make and receive calls and text messages.

    How do I obtain a GPS fix on an iSatPhone?
    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.
