Iridium System Time Change on March 3, 2015: Impact for Satellite Phone Users

On March 3, 2015 at 18:00:00 UTC, Iridium will change the Iridium L-Band system time count from “ERA1” to “ERA2”. As part of standard satellite network operations and maintenance Iridium periodically resets the Iridium L-Band count.

For Iridium Satellite Phone users:  (Excludes Iridium GO! and devices shipped after February 23, 2015)

The planned epoch time change will have no impact to service availability and the ability to successfully complete phone calls, SMS messages, or data services however; display time will revert to December 29, 2007 7:26:29 UTC if no action is taken.

Iridium 9555 and Iridium Extreme® customers can restore the correct time settings by following these steps:

1. Dial *#99#2014051114235500#

2. Press the green key

3. Turn off/on their phone

For Iridium 9500, 9505 and 9505A customers, they will need to set the updated time and date from their phone menu. The extended phone set-up menu must be set to “On” (see page 137 of Iridium 9505A user guide, page 149 of the Iridium 9500 user guide, or page 139 of the Iridium 9505 user guide), then follow these instructions to set time and date:
