here's a rate sheet from a different vendor
http://www.deltawavecomm.com/Files/IsatPhonePro/DWSATPHONEPROPOSTPAIDPREPAID.pdf$15 per month, you pay $1 per minute when you use it. This kills every Iridium plan or prepaid deal if you need it for a month or more per year.
There are no prepaid plans available in the US, so the $15 per month are there. Given I paid $150 for SPOT with tracking, this is no change for me. I pay more for my son's phone data plan ($30 per month)
