New IsatPhone Pro Firmware available

6 October, 2015 Inmarsat IsatPhone Pro

Inmarsat just released a firmware upgrade for IsatPhone Pro handset: version 5.11.0.

Firmware version 5.11.0 supersedes the firmware version 5.8.0 that was released in March 2015.


  • For users of 5.3.0 or higher this is a recommended upgrade, meaning that the features introduced by the firmware are important but not critical for the GSPS service, including the network and the IsatPhone Pro handset.
  • For users who have not yet upgraded to version 5.3.0 or higher, this upgrade to 5.8.0 is considered ‘mandatory’ to avoid the phone becoming non-operational.
