Agree with Allan B re the $4/min call cost via Iridium/Telstra and balancing call cost against standing cost. We have a dedicated SIM on the Telstra Mobile Accelerate Casual Plan ($10/mo) for our Iridium 9555. (If we had a regular Telstra mobile service on a plan we'd SIM-swap from that, but there isn't one that suits our regular life usage). Apart from our winter
treks in Oz, took it to US and Canada for some of our remote stuff there in cellphoneless territory.
$120/year, and no calls made/received to date except testing. Carry an Optus-based cellphone and one on a (short-term) Telstra plan when travelling out there, as Optus have done a LOT of infill in the last three years so you really need both.
We keep abreast of evolving coverage on both those networks (VFAU are useless away from big smoke) so if there is a domestic emergency requiring those back
home to call us, we would advise when we are next in cellphone coverage and keep the call duration short, returning the call later if appropriate.
May not be everyone's best solution, as I know some feel the need for daily checkins - a Pivotel plan may work out best with that sort of calling pattern. But the amount we save on our "daily" plan (also $10/mo, on Telstra wholesale) compared to regular T plans more than covers the satphone SIM standing cost.
