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 that who have not yet upgraded to version 5.3.0 or higher, this upgrade to 5.17.2 is considered to be ‘mandatory’ to avoid the phone becoming non-operational.
To check you have the latest version on your IsatPhone Pro, go to Menu > Settings > About > Firmware version.
