All IsatPhone Pro users must ensure that they update their firmware to version v 5.3.0 before network enhancements are carried out in early 2014.
Features introduced in firmware v 5.3.0 are vitally important for continued use of the IsatPhone Pro service, and users who have not upgraded to the new firmware by the time network enhancements take place, will not be able to register on the network to make or receive calls.
The network enhancements are scheduled to take place on the following dates:
13th January – I-4 Alphasat (EMEA)
27th January – I-4 F3 (Asia-Pacific)
10th February – I-4 F1 (Americas)
No service outages are expected during the network changes.
Firmware version v 5.3.0 is available for download from the Support section of the Inmarsat website:
