Iridium 9555 — firmware

Firmware updates for the Iridium 9555 handset. The 9555 is a long-lived device and most firmware updates address minor compatibility and battery issues.

Checking your version

From the 9555 home screen:

  1. Menu → Setup → About
  2. Note the Software version

How to update

Use Iridium Update Manager on Windows with the supplied USB cable. The process is the same as for the 9575 Extreme — installation, connection, follow prompts, do not interrupt.
