We are pleased to inform you that a new IsatPhone Pro firmware version 5.6.1 has been released and is available for download from the Inmarsat website at:
http://www.inmarsat.com/support/isatphone-pro-support/
For users of 5.3.0 firmware 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 5.6.1 is considered ‘mandatory’ to avoid the phone becoming non-operational.
For any questions you may have please contact us.
