Lo ho comprato su Amazon. Fortunatamente non ho avuto il piacere di provare i servizi di GEOS. Ecco cosa dicono le FAQ:
First, the IERCC has an extensive database and relationships with first response agencies and Rescue Coordination Centers around the Globe. The IERCC will contact the appropriate responsible agency based on incident information such as incident location coordinates, aviation or maritime incident, or other information available to the IERCC.
Second, when the IERCC receives and alert from your device, information that you have entered into your profile is immediately available to them, such as emergency contacts. You have the ability in your profile to enter up to two of them and we strongly advise you to do so. It is up to you to a) keep the emergency contact information updated and b) ensure, if you are taking a trip, your emergency contacts have information about where you are going, for how long and information about the number in your party. This can all help to expedite a response in case of emergency.
