Iridium 9555 - Re-Epoch Time and Date

If you have an Iridium 9555 that has not been used for an extended period of time, you may notice the time and date are incorrect and do not update automatically, even after connecting to the satellite network.

On March 3, 2015, Iridium completed an Epoch that required phones to follow the procedure below to display the correct time.
