IsatPhone PRO current firmware: 5.17.2
For users of firmware 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 service, including the network and the IsatPhone Pro handset. The 5.17.2 update is mandatory only for users covered by the MEAS (I4-F2) satellite region.
If your IsatPhone PRO satellite phone's firmware version is lower than 5.3.0, your phone will NOT operate properly. You must update to the latest firmware in order to use your Inmarsat Pro phone and service.
To check your phone's firmware version, go to Menu > Settings > About > Firmware version.
You can download the firmware update tool and instructions at Inmarsat's support webpage.
Please note that Inmarsat discontinued any further customer support and firmware updates for IsatPhone Pro in October 2019.
