Why does it need always-on receive? Any number of data acquisition apps can just wake-up on a set schedule, power that modem on, send their data, and get any action/responses at the same time then power everything back down. So the W/h numbers could still be quite trivial. And presumably much of the power is as you mention transmit, because its talking to a satellite, not a device 1/2 a mile away.
