Inmarsat IsatPhone Pro drivers and firmware officially lost support on October 1, 2019, when Inmarsat ended customer support, firmware upgrades, repairs, and warranty coverage for the IsatPhone Pro. Existing phones continued to function with active SIM cards and subscriptions, but no further official software or driver updates were released after firmware version 5.17.2. Following Inmarsat’s acquisition, support resources were later moved under Viasat.
