But I'm still interested whether this 777 is equipped with Satphones...
The aircraft appears to have been fitted with an Inmarsat Aero L package which works through an omni-directional antenna in the global beams of the I-3 series of satellites.
Aero L is used for low speed (600 - 1200 bps) real-time, packet data comms used mainly for ATC (CPDLC) and ACARS services.
In short, no SatPhone services.
