During 23-29 May 2010 Iridium will run its fourth annual “Test Your Satellite Phone” Week. Some satellite phones are used for emergencies only and so are not regularly tested. To avoid problems when you need the phone at that critical moment Iridium advise you to complete a call to their free number (00-1-480-752-5105) from your Iridium sat phone. Callers will hear a recorded voice message confirming they completed the call successfully and offering refresher tips for using the phones. Sat phone users subscribed to networks other than Iridium can also use this procedure but they may be charged for the call. For more information visit www.testyoursatellitephone.com.
