Inmarsat has asked Roadpost to inform all customers of a critical firmware update that must be completed by November 28th 2014. If your device is not updated you will no longer obtain a satellite signal with your IsatPhone Pro.
The latest firmware version 5.6.1 is available and can be found on the Roadpost Support Center: http://support.roadpost.com/kb/articles/244-isatphone-pro-firmware-version-5-6-1. This update will ensure that you will be able to continue service beyond the November 28th deadline.
Thank you for your co-operation in this matter.
